目录
🍁整合SpringMVC
- 1.先创建个SpringBoot项目，导入依赖
<parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.2.RELEASE</version></parent><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies>
- 创建个启动类
@SpringBootApplication
public class Application {
public staticvoidmain(String[] args){
SpringApplication.run(Application.class,args);}}
- 创建实体类User
public class User {
private String username ;
private String password ;
private Integer age ;
private String sex ;
public String getUsername(){return username;}
public voidsetUsername(String username){
this.username = username;}
public String getPassword(){return password;}
public voidsetPassword(String password){
this.password = password;}
public Integer getAge(){return age;}
public voidsetAge(Integer age){
this.age = age;}
public String getSex(){return sex;}
public voidsetSex(String sex){
this.sex = sex;}
@Override
public String toString(){return"User{"+"username='"+ username +'\''+", password='"+ password +'\''+", age="+ age +", sex='"+ sex +'\''+'}';}}
- 编写Controller类
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping("/findAll")
@ResponseBody
public List<User>findAll(){//查询所有
List<User> users = new ArrayList<User>();
User user1 = new User();
user1.setUsername("xfx");
user1.setPassword("123456");
user1.setAge(20);
user1.setSex("男");
User user2 = new User();
user2.setUsername("mks");
user2.setPassword("234567");
user2.setAge(34);
user2.setSex("女");
User user3 = new User();
user3.setUsername("ls");
user3.setPassword("34567");
user3.setAge(34);
user3.setSex("女");
users.add(user1);
users.add(user2);
users.add(user3);return users;}}
- 测试
🍁静态资源目录
- 在springboot中有一个叫做ResourceProperties的类，里面就定义了静态资源的默认查找路径：
- 默认的静态资源路径为： • classpath:/META-INF/resources/ • classpath:/resources/ • classpath:/static/ • classpath:/public
- 在项目中创建路径进行测试
- 在static目录下创建index.html文件
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>static目录下的静态页面</title></head><body><h1>static目录下的静态页面</h1></body></html>
- 在public目录下创建public.html文件
<!DOCTYPE html><html lang="en"><head><meta charset="UTF-8"><title>public目录下的静态页面</title></head><body><h1>public目录下的静态页面</h1></body></html>
🍁自定义拦截器
- SpringMVC中配置拦截器的步骤 : - 编写一个拦截器(实现HandlerInterceptor接口)- 注册拦截器(mvc:interceptors)
- SpringBoot实现拦截器的具体步骤: - 编写一个拦截器
@Component
public class MyInterceptor implements HandlerInterceptor {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
System.out.println("preHandle方法执行....");return false;}
@Override
public voidpostHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
System.out.println("postHandle方法执行....");}
@Override
public voidafterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
System.out.println("afterCompletion方法执行....");}}
- 通过WebMvcConfigurer注册拦截器
@Configuration
public class MVCConfig implements WebMvcConfigurer {
@Autowired
private MyInterceptor myInterceptor;
@Override
public voidaddInterceptors(InterceptorRegistry registry){
registry.addInterceptor(myInterceptor).addPathPatterns("/user/findAll").addPathPatterns("/public.html").excludePathPatterns("/index.html");}}
- 测试拦截效果
