前言
大家好，本文是基于 SpringBoot 从0搭建一个企业级开发项目，基于SpringBoot 的项目，并集成MyBatis-Plus、Druid、Logback 等主流技术。希望对大家有所帮助~
目录
一、概述
随着技术栈的不断更新迭代，我们需要快速的在企业中搭建一个项目，并使用市面上前沿且稳定的技术栈。本期将跟大家一起从0到1搭建一个基于SpringBoot 的项目，并集成MyBatis-Plus、Druid、Logback 等主流技术。后续也会整合 Docker，自定义构建 Docker 项目，实现 Docker Compose 部署。源码附在文末。
二、创建统一的依赖管理
2.1、统一的依赖管理工程创建
创建一个名称为
my-project-dependencies
的项目，该项目负责统一的依赖管理
pom.xml
内容如下：

2.2、Maven托管
将其交给
Maven
托管
三、创建通用模块
3.1、创建通用模块工程
创建一个名称为
my-project-common
的项目，该项目负责通用的类库以及工具类
pom.xml
内容如下：
<?xml version="1.0" encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.micromaple</groupId><artifactId>my-project-dependencies</artifactId><version>1.0.0-SNAPSHOT</version><relativePath>../my-project-dependencies/pom.xml</relativePath></parent><artifactId>my-project-common</artifactId><packaging>jar</packaging><name>my-project-common</name><dependencies><!-- Commons Begin--><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId></dependency><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId></dependency><!-- Commons End--><!-- Environment Begin --><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId></dependency><dependency><groupId>com.google.guava</groupId><artifactId>guava</artifactId></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><dependency><groupId>commons-collections</groupId><artifactId>commons-collections</artifactId></dependency><!-- Environment End --><!-- Apache Http Begin --><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>fluent-hc</artifactId></dependency><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpmime</artifactId></dependency><!-- Apache Http End --></dependencies></project>
3.2、Maven托管
可以使用右侧的
Maven
的
+
号来进行项目的托管。
3.3、完善目录结构
创建
src/main/java
目录后，创建包名，包名为：
com.micromaple.my.project.common
此工程是放一些通用的类库或者是工具类之类的。
3.4、定义通用类库
3.4.1、返回状态码
创建常量包
constant
。
通用常量返回状态码
HttpStatus
packagecom.micromaple.my.project.common.constant;/**
* 返回状态码
* Title: HttpStatus
* Description:
*
* @author Micromaple
*/publicclassHttpStatus{/**
* 操作成功
*/publicstaticfinalint SUCCESS =200;/**
* 对象创建成功
*/publicstaticfinalint CREATED =201;/**
* 请求已经被接受
*/publicstaticfinalint ACCEPTED =202;/**
* 操作已经执行成功，但是没有返回数据
*/publicstaticfinalint NO_CONTENT =204;/**
* 资源已被移除
*/publicstaticfinalint MOVED_PERM =301;/**
* 重定向
*/publicstaticfinalint SEE_OTHER =303;/**
* 资源没有被修改
*/publicstaticfinalint NOT_MODIFIED =304;/**
* 参数列表错误（缺少，格式不匹配）
*/publicstaticfinalint BAD_REQUEST =400;/**
* 未授权
*/publicstaticfinalint UNAUTHORIZED =401;/**
* 访问受限，授权过期
*/publicstaticfinalint FORBIDDEN =403;/**
* 资源，服务未找到
*/publicstaticfinalint NOT_FOUND =404;/**
* 不允许的http方法
*/publicstaticfinalint BAD_METHOD =405;/**
* 资源冲突，或者资源被锁
*/publicstaticfinalint CONFLICT =409;/**
* 不支持的数据，媒体类型
*/publicstaticfinalint UNSUPPORTED_TYPE =415;/**
* 系统内部错误
*/publicstaticfinalint ERROR =500;/**
* 接口未实现
*/publicstaticfinalint NOT_IMPLEMENTED =501;}
3.4.2、通用返回结果
创建数据传输包
dto
。
通用数据传输返回结果
BaseResult
packagecom.micromaple.my.project.common.dto;importcom.micromaple.my.project.common.constant.HttpStatus;importjava.util.HashMap;/**
* 返回结果
* Title: BaseResult
* Description:
*
* @author Micromaple
*/publicclassBaseResultextendsHashMap<String,Object>{privatestaticfinallong serialVersionUID =1L;/**
* 状态码
*/publicstaticfinalString CODE_TAG ="code";/**
* 返回内容
*/publicstaticfinalString MSG_TAG ="msg";/**
* 数据对象
*/publicstaticfinalString DATA_TAG ="data";/**
* 初始化一个新创建的 BaseResult 对象，使其表示一个空消息。
*/publicBaseResult(){}/**
* 初始化一个新创建的 BaseResult 对象
*
* @param code 状态码
* @param msg 返回内容
*/publicBaseResult(int code,String msg){super.put(CODE_TAG, code);super.put(MSG_TAG, msg);}/**
* 初始化一个新创建的 BaseResult 对象
*
* @param code 状态码
* @param msg 返回内容
* @param data 数据对象
*/publicBaseResult(int code,String msg,Object data){super.put(CODE_TAG, code);super.put(MSG_TAG, msg);super.put(DATA_TAG, data);}/**
* 返回成功消息
*
* @return 成功消息
*/publicstaticBaseResultsuccess(){returnBaseResult.success("操作成功");}/**
* 返回成功数据
*
* @return 成功消息
*/publicstaticBaseResultsuccess(Object data){returnBaseResult.success("操作成功", data);}/**
* 返回成功消息
*
* @param msg 返回内容
* @return 成功消息
*/publicstaticBaseResultsuccess(String msg){returnBaseResult.success(msg,null);}/**
* 返回成功消息
*
* @param msg 返回内容
* @param data 数据对象
* @return 成功消息
*/publicstaticBaseResultsuccess(String msg,Object data){returnnewBaseResult(HttpStatus.SUCCESS, msg, data);}/**
* 返回错误消息
*
* @return
*/publicstaticBaseResulterror(){returnBaseResult.error("操作失败");}/**
* 返回错误消息
*
* @param msg 返回内容
* @return 警告消息
*/publicstaticBaseResulterror(String msg){returnBaseResult.error(msg,null);}/**
* 返回错误消息
*
* @param msg 返回内容
* @param data 数据对象
* @return 警告消息
*/publicstaticBaseResulterror(String msg,Object data){returnnewBaseResult(HttpStatus.ERROR, msg, data);}/**

创建好后，目录结构效果如下：
四、创建项目服务模块
4.1、创建项目服务模块工程
创建一个名称为
my-project-server
的项目，该项目负责实现具体业务，以及提供服务。
pom.xml
内容如下：
<?xml version="1.0" encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.micromaple</groupId><artifactId>my-project-dependencies</artifactId><version>1.0.0-SNAPSHOT</version><relativePath>../my-project-dependencies/pom.xml</relativePath></parent><artifactId>my-project-server</artifactId><packaging>jar</packaging><name>my-project-server</name><dependencies><!-- Project Begin --><dependency><groupId>com.micromaple</groupId><artifactId>my-project-common</artifactId><version>1.0.0-SNAPSHOT</version></dependency><!-- Project End --><!-- Spring Boot Begin --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid-spring-boot-starter</artifactId></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-validation</artifactId></dependency><!-- Spring Boot End --><!-- Junit --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><!-- Environment Begin --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><!-- Environment End --><!-- Common Begin --><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId></dependency><!-- Common End --></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><mainClass></mainClass></configuration></plugin></plugins></build></project>

Maven
的
+
号来进行项目的托管。
4.3、完善目录结构
创建
src/main/java
和
src/main/resource
目录
在
src/main/java
目录下创建包名，包名为：
com.micromaple.my.project.server
在
src/main/resource
目录下创建
application.yml
，内容如下：
# Spring配置spring:jackson:#时间戳统一转换为指定格式date-format: yyyy-MM-dd HH:mm:ss
# 时区修改为东8区time-zone: GMT+8
server:port:8899
4.4、创建 Application
这里使用 Spring 提供的 MyBatis 包扫面注解
packagecom.micromaple.my.project.server;importorg.mybatis.spring.annotation.MapperScan;importorg.springframework.boot.SpringApplication;importorg.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication@MapperScan(value ="com.micromaple.my.project.server.mapper")publicclassMyProjectServerApplication{publicstaticvoidmain(String[] args){SpringApplication.run(MyProjectServerApplication.class, args);}}
在
pom.xml
中的 mainClass 指定该 Application
<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><configuration><mainClass>com.micromaple.my.project.server.MyProjectServerApplication</mainClass></configuration></plugin></plugins></build>
4.5、整合 Logback
在
src/main/resource
目录下创建
logback-spring.xml
，内容如下：
<?xml version="1.0" encoding="UTF-8"?><configuration><substitutionPropertyname="logBase"value="./logs/"/><substitutionPropertyname="logName"value="my-project-server"/><substitutionPropertyname="logPatternExp"value="%date{YYYY-MM-dd HH:mm:ss.SSS} [%-5level] [%thread] %logger{9999} %L -=> %msg%n"/><appendername="console"class="ch.qos.logback.core.ConsoleAppender"><encoder><pattern>${logPatternExp}</pattern></encoder></appender><appendername="rollingFile"class="ch.qos.logback.core.rolling.RollingFileAppender"><file>${logBase}${logName}.log</file><rollingPolicyclass="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"><fileNamePattern>${logBase}${logName}-%d{yyyy-MM-dd}-%i.zip</fileNamePattern><maxHistory>180</maxHistory><timeBasedFileNamingAndTriggeringPolicyclass="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP"><maxFileSize>30MB</maxFileSize></timeBasedFileNamingAndTriggeringPolicy></rollingPolicy><encoder><pattern>${logPatternExp}</pattern></encoder></appender><!-- project default level --><loggername="com.micromaple.my.project.server"level="DEBUG"/><loggername="org.springframework"level="ERROR"/><!-- root --><rootlevel="DEBUG"><appender-refref="console"/><appender-refref="rollingFile"/></root></configuration>
在
application.yml
增加配置：
logging:config: classpath:logback-spring.xml
4.6、整合 Druid 数据库连接池
在
src/main/resource
目录下创建
application-druid.yml
，内容如下：
spring:datasource:type: com.alibaba.druid.pool.DruidDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://192.168.110.135:3306/my-project?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8username: root
password:123456druid:#连接池配置 初始化连接池的连接数量 大小，最小，最大initial-size:5min-idle:5max-active:20#配置获取连接等待超时的时间max-wait:60000#配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒time-between-eviction-runs-millis:60000# 配置一个连接在池中最小生存的时间，单位是毫秒min-evictable-idle-time-millis:30000validation-query: SELECT 1 FROM DUAL

reset-enable:true#设置监控页面的登录名和密码login-username: admin
login-password: admin
allow: 127.0.0.1
在
application.yml
增加配置，内容如下：
# Spring配置spring:# 启用指定配置文件#（文件名需满足application-{profile}.yml的格式）profiles:active: druid
application.yml
完整配置如下：
# Spring配置spring:jackson:#时间戳统一转换为指定格式date-format: yyyy-MM-dd HH:mm:ss
# 时区修改为东8区time-zone: GMT+8
# 启用指定配置文件#（文件名需满足application-{profile}.yml的格式）profiles:active: druid
server:port:8899logging:config: classpath:logback-spring.xml
最终项目效果图如下：
五、创建代码生成模块
5.1、创建代码生成模块工程
创建一个名称为
my-project-generator
的项目，该项目负责通过数据库自动生成通用的增删改查。
pom.xml
内容如下：
<?xml version="1.0" encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>com.micromaple</groupId><artifactId>my-project-dependencies</artifactId><version>1.0.0-SNAPSHOT</version><relativePath>../my-project-dependencies/pom.xml</relativePath></parent><artifactId>my-project-generator</artifactId><packaging>jar</packaging><name>my-project-generator</name><dependencies><!-- Project Begin --><dependency><groupId>com.micromaple</groupId><artifactId>my-project-common</artifactId><version>1.0.0-SNAPSHOT</version></dependency><!-- Project End --><!-- Spring Boot Begin --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId></dependency><!-- Spring Boot End --><!-- Junit --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><!-- Environment Begin --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-mail</artifactId></dependency><!-- Environment End --><!-- MP 代码生成工具需要的依赖1 velocity-engine-core 2 slf4j-api 3slf4j-log4j12 --><!-- Apache velocity --><dependency><groupId>org.apache.velocity</groupId><artifactId>velocity-engine-core</artifactId></dependency><!--freemarker模板--><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId></dependency><!-- Common End --><!--mybatis-plus代码生成器--><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-generator</artifactId></dependency></dependencies></project>
5.2、Maven托管
可以使用右侧的
Maven
的
+
号来进行项目的托管。
5.3、完善目录结构
创建
src/main/java
和
src/main/resource
目录
在
src/main/java
目录下创建包名，包名为：
com.micromaple.my.project.generator
。
创建代码生成类，内容如下：
packagecom.micromaple.my.project.generator;importcom.baomidou.mybatisplus.generator.FastAutoGenerator;importcom.baomidou.mybatisplus.generator.config.DataSourceConfig;importcom.baomidou.mybatisplus.generator.config.OutputFile;importcom.baomidou.mybatisplus.generator.config.StrategyConfig;importcom.baomidou.mybatisplus.generator.config.converts.MySqlTypeConvert;importcom.baomidou.mybatisplus.generator.config.querys.MySqlQuery;importcom.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;importcom.baomidou.mybatisplus.generator.keywords.MySqlKeyWordsHandler;importjava.util.Collections;/**
* 代码生成
* Title: GeneratorApplication
* Description:
*
* @author Micromaple
*/publicclassGeneratorApplication{publicstaticvoidmain(String[] args){String projectPath =System.getProperty("user.dir");String finalProjectPath = projectPath +"/my-project-generator";// 数据源配置DataSourceConfig.Builder dataSourceConfig =newDataSourceConfig
.Builder("jdbc:mysql://192.168.110.135:3306/my-project?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=false&serverTimezone=GMT%2B8","root","123456").dbQuery(newMySqlQuery()).typeConvert(newMySqlTypeConvert()).keyWordsHandler(newMySqlKeyWordsHandler());newStrategyConfig.Builder().serviceBuilder().formatServiceFileName("%sService").formatServiceImplFileName("%sServiceImp").build();FastAutoGenerator.create(dataSourceConfig).globalConfig(builder ->{
builder.author("Micromaple")//设置作者.commentDate("yyyy-MM-dd HH:mm:ss")//注释日期.outputDir(finalProjectPath +"/src/main/java");//指定输出目录}).packageConfig(builder ->{
builder.parent("com.micromaple.my.project.server").moduleName("")// 设置父包模块名.entity("domain")//设置entity包名//.other("model.dto") // 设置dto包名.pathInfo(Collections.singletonMap(OutputFile.mapperXml, finalProjectPath +"/src/main/resources/mapper"));// 设置mapperXml生成路径}).strategyConfig(builder ->{
builder.addInclude("sys_user")// 设置需要生成的表名.addTablePrefix("tb_");// 设置过滤表前缀
builder.entityBuilder().enableLombok();//开启 lombok 模型
builder.entityBuilder().enableTableFieldAnnotation();//开启生成实体时生成字段注解
builder.controllerBuilder().enableRestStyle();//开启生成@RestController 控制器}).templateEngine(newFreemarkerTemplateEngine())// 使用Freemarker引擎模板，默认的是Velocity引擎模板.execute();}}
5.4、测试代码生成
建表语句：
CREATETABLE`sys_user`(`id`intNOTNULLAUTO_INCREMENTCOMMENT'主键',`code`varchar(100)COLLATE utf8mb4_general_ci DEFAULTNULLCOMMENT'编号',`name`varchar(50)COLLATE utf8mb4_general_ci DEFAULTNULLCOMMENT'姓名',`sex`varchar(2)COLLATE utf8mb4_general_ci DEFAULTNULLCOMMENT'性别',`age`intDEFAULTNULLCOMMENT'年龄',`birthday`dateDEFAULTNULLCOMMENT'生日',`mail`varchar(50)COLLATE utf8mb4_general_ci DEFAULTNULLCOMMENT'邮箱',`created_date`datetimeDEFAULTCURRENT_TIMESTAMPCOMMENT'创建时间',`updated_date`datetimeDEFAULTNULLCOMMENT'更新时间',PRIMARYKEY(`id`))ENGINE=InnoDBAUTO_INCREMENT=2DEFAULTCHARSET=utf8mb4 COLLATE=utf8mb4_general_ci COMMENT='用户表'
新增数据：
insertinto`sys_user`(`code`,`name`,`sex`,`age`,`birthday`,`mail`,`created_date`,`updated_date`)values('admin','超级管理员','男','18','2004-01-01','[email protected]','2022-09-21 21:48:33',NULL);
执行
GeneratorApplication
类的 main 方法后，可以看到生成的代码，效果如下图：
将其拷贝到
my-project-server
工程模块中，完整效果如下：
5.5、测试生成效果
我们在
my-project-server
工程编写单元测试，测试生成的代码是否可用。
创建
src/test/java
目录，在该目录创建包
com.micromaple.my.project.server.service
；
接着创建测试类
SysUserServiceTest
，内容如下：
packagecom.micromaple.my.project.server.service;importcom.micromaple.my.project.server.MyProjectServerApplication;importcom.micromaple.my.project.server.domain.SysUser;importorg.junit.Test;importorg.junit.runner.RunWith;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.boot.test.context.SpringBootTest;importorg.springframework.test.context.junit4.SpringRunner;importjava.util.List;@SpringBootTest(classes =MyProjectServerApplication.class)@RunWith(SpringRunner.class)publicclassSysUserServiceTest{@AutowiredprivateISysUserService sysUserService;/**
* 测试新增
*/@TestpublicvoidaddTest(){SysUser sysUser =newSysUser();
sysUser.setCode("user");
sysUser.setName("用户");
sysUser.setSex("女");
sysUser.setAge(18);boolean save = sysUserService.save(sysUser);System.out.println(save);// 输出 true 代表插入成功}/**
* 测试查询
*/@TestpublicvoidselectTest(){List<SysUser> sysUsers = sysUserService.getBaseMapper().selectList(null);for(SysUser sysUser : sysUsers){System.out.println(sysUser.getName());}/**
* 输出内容如下：
* 超级管理员
* 用户
*/}}
5.6、测试 Controller 层
SysUserController 代码如下：
packagecom.micromaple.my.project.server.controller;importcom.micromaple.my.project.common.dto.BaseResult;importcom.micromaple.my.project.common.utils.MapperUtils;importcom.micromaple.my.project.server.domain.SysUser;importcom.micromaple.my.project.server.service.ISysUserService;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;importjava.util.List;/**
* <p>
* 用户表 前端控制器
* </p>
*
* @author Micromaple
* @since 2022-09-21 21:51:15
*/@RestController@RequestMapping("/sys-user")publicclassSysUserController{@AutowiredprivateISysUserService sysUserService;@GetMapping("/get/all")publicBaseResultgetAll(){List<SysUser> sysUsers = sysUserService.getBaseMapper().selectList(null);returnBaseResult.success(sysUsers);}}
启动
MyProjectServerApplication
服务，访问地址：
http://localhost:8899/sys-user/get/all
效果如下：
