Spring Security 拦截问题

Spring Security是干啥的我就不想解释了, 毕竟百度上面的讲解一大堆解说的可是会比我细致😄。

开发的时候我们经常需要对部分的@RequestMapping设置为 public api 不需要登陆也可以访问如登陆接口等等。偏爱Spring注解编程，那我们就基于注解的方式来忽略Spring Security的拦截吧。

  1. publicclassSecurityConfigurerextendsWebSecurityConfigurerAdapter{WebSecurity.IgnoredRequestConfigurer ignoring = web.ignoring();
  2.      ignoring.antMatchers("/login");
  3.      ignoring.antMatchers("/public api...");}

就如我们上面代码展示的一样，我们经常需要对Spring Security的忽略名单进行硬编码配置或者配置文件配置我都感觉挺繁琐的，Spring都已经提倡基于注解编程了，百度到的内容居然还是教我用硬编码所以下面我们就基于注解来实现Spring Security忽略拦截的实现吧。

一个注解搞定Spring Security 忽略拦截

本章节我们就用注解的方式来实现Spring Security忽略拦截吧。本章会分别介绍基于注解方式和配置文件方式

  • 注解主要针对@RequestMapping进行忽略
  • 配置文件主要针对静态文件（js，html，css，…）进行忽略

环境配置

  • Spring Boot 2.5.X - Spring MVC- Spring Security- lombok
  • Java 1.8

因为是单纯的演示一下如何基于注解忽略Spring Security拦截，所以只会使用最小demo而不是大篇长论的去魔改Spring Security（其实是我懒得写啦反正百度都有😄）
老规矩下面直接放代码吧。

代码就需要大家去start.spring.io生成一下啦，然后改一下Spring Boot的版本号，或者去我的GitHub直接clone代码： galaxy-sea/galaxy-blogs

SecurityConfiguration 配置类

  1. @Configuration@EnableWebSecuritypublicclassSecurityConfigurationextendsWebSecurityConfigurerAdapter{@Overridepublicvoidconfigure(WebSecurity web){WebSecurity.IgnoredRequestConfigurer ignoring = web.ignoring();
  2.     ignoring.antMatchers(HttpMethod.GET,"/hello/hardcode");}}

HelloController用于测试Spring Security拦截器

  1. importorg.springframework.web.bind.annotation.GetMapping;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RestController;/**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@RestController@RequestMapping("hello")publicclassHelloController{@GetMapping("/security")publicStringsecurity(){return"Hello, Security";}@GetMapping("/hardcode")publicStringhardcode(){return"Hello, hardcode";}}

测试结果

  1. # 测试结果1curl http://127.0.0.1:8080/hello/security -i
  2. HTTP/1.1 401 
  3. Content-Type: application/json
  5. {"timestamp":"2022-12-16T10:54:44.403+00:00","status":401,"error":"Unauthorized","path":"/hello/security"}# 测试结果2curl http://127.0.0.1:8080/hello/hardcode -i
  6. HTTP/1.1 200 
  7. Content-Type: text/plain;charset=UTF-8
  9. Hello, hardcod

基于注解形式

其实硬编码这种处理方式如果public api较少的情况下还是没有问题的，但是public api变多了就不是很友好了。
那么现在我们就基于注解的形式实现一下吧，代码量及其精简的哦。

首先我们创建一个

  1. IgnoreWebSecurity

注解用户将api设置为public api, 然后我们改造一下

  1. SecurityConfiguration

类。

IgnoreWebSecurity

  1. importjava.lang.annotation.Documented;importjava.lang.annotation.ElementType;importjava.lang.annotation.Inherited;importjava.lang.annotation.Retention;importjava.lang.annotation.RetentionPolicy;importjava.lang.annotation.Target;/**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/1/3
  4.  */@Target({ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Inherited@Documentedpublic@interfaceIgnoreWebSecurity{}

改造 SecurityConfiguration

  1. /**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@Configuration@EnableWebSecurity@RequiredArgsConstructorpublicclassSecurityConfigurationextendsWebSecurityConfigurerAdapter{privatefinalRequestMappingHandlerMapping requestMappingHandlerMapping;@Overridepublicvoidconfigure(WebSecurity web){WebSecurity.IgnoredRequestConfigurer ignoring = web.ignoring();
  5.     ignoring.antMatchers(HttpMethod.GET,"/hello/hardcode");this.ignoreAnnotation(ignoring,this.requestMappingHandlerMapping);}privatevoidignoreAnnotation(WebSecurity.IgnoredRequestConfigurer ignoring,RequestMappingHandlerMapping requestMappingHandlerMapping){Map<RequestMappingInfo,HandlerMethod> handlerMethods = requestMappingHandlerMapping.getHandlerMethods();for(Map.Entry<RequestMappingInfo,HandlerMethod> entry : handlerMethods.entrySet()){HandlerMethod handlerMethod = entry.getValue();if(handlerMethod.hasMethodAnnotation(IgnoreWebSecurity.class)){Set<String> patternValues = entry.getKey().getPatternValues();Set<RequestMethod> methods = entry.getKey().getMethodsCondition().getMethods();if(CollectionUtils.isEmpty(methods)){// RequestMapping没有指定method
  6.           ignoring.antMatchers(patternValues.toArray(newString[0]));}else{for(RequestMethod method : methods){// RequestMapping指定了method
  7.             ignoring.antMatchers(HttpMethod.resolve(method.name()), patternValues.toArray(newString[0]));}}}}}}

HelloController 增加一下测试方法

  1. /**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@RestController@RequestMapping("hello")publicclassHelloController{/** 注解方式 */@GetMapping("/annotation")@IgnoreWebSecuritypublicStringannotation(){return"Hello, annotation";}/** 测试PathVariable参数 */@GetMapping("/{path}/annotation")@IgnoreWebSecuritypublicStringannotationPath(@PathVariableString path){return"Hello, annotation. path: "+ path;}}

测试结果

  1. # 测试注解curl http://127.0.0.1:8080/hello/annotation -i
  2. HTTP/1.1 200 
  3. Content-Type: text/plain;charset=UTF-8
  4. Content-Length: 17
  5. Date: Sun, 18 Dec 202212:25:05 GMT
  7. Hello, annotatio
  9. # 测试注解curl http://127.0.0.1:8080/hello/public_api/annotation -i
  10. HTTP/1.1 200 
  11. Content-Type: text/plain;charset=UTF-8
  12. Content-Length: 35
  13. Date: Sun, 18 Dec 202212:25:35 GMT
  15. Hello, annotation. path: public_api

通过解析

  1. RequestMappingHandlerMapping

我们就可以将api设置为public api了。这种方式大大简便的配置。

基于配置形式

上一章我们通过注解的方式去将api设置为public api但是这种方式对静态资源（html，js，css等）并不是很友好，好需要通过配置的文件的方式将一些静态资源设置为public，所以本章节通过配置文件方式来实现public api的忽略拦截

创建一个配置文件

  1. IgnoreWebSecurityProperties

来配置

IgnoreWebSecurityProperties

  1. /**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@Data@ConfigurationProperties(prefix ="security.ignoring")publicclassIgnoreWebSecurityProperties{/** 需要忽略的 URL 格式，不考虑请求方法 */privateString[] pattern ={};/** 需要忽略的 GET 请求 */privateString[] get ={};/**  需要忽略的 POST 请求 */privateString[] post ={};/**  需要忽略的 DELETE 请求 */privateString[] delete ={};/**  需要忽略的 PUT 请求 */privateString[] put ={};/** 需要忽略的 HEAD 请求 */privateString[] head ={};/** 需要忽略的 PATCH 请求 */privateString[] patch ={};/** 需要忽略的 OPTIONS 请求 */privateString[] options ={};/** 需要忽略的 TRACE 请求 */privateString[] trace ={};}

改造 IgnoreWebSecurityProperties

  1. /**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@Configuration@EnableWebSecurity@RequiredArgsConstructor@EnableConfigurationProperties(IgnoreWebSecurityProperties.class)publicclassSecurityConfigurationextendsWebSecurityConfigurerAdapter{privatefinalIgnoreWebSecurityProperties ignoreWebSecurityProperties;privatefinalRequestMappingHandlerMapping requestMappingHandlerMapping;@Overridepublicvoidconfigure(WebSecurity web){WebSecurity.IgnoredRequestConfigurer ignoring = web.ignoring();
  5.     ignoring.antMatchers(HttpMethod.GET,"/hello/hardcode");this.ignoreAnnotation(ignoring,this.requestMappingHandlerMapping);this.ignoreProperties(ignoring,this.ignoreWebSecurityProperties);}...privatevoidignoreProperties(WebSecurity.IgnoredRequestConfigurer ignoring,IgnoreWebSecurityProperties ignoreWebSecurityProperties){
  6.     ignoring.antMatchers(HttpMethod.GET, ignoreWebSecurityProperties.getGet()).antMatchers(HttpMethod.POST, ignoreWebSecurityProperties.getPost()).antMatchers(HttpMethod.DELETE, ignoreWebSecurityProperties.getDelete()).antMatchers(HttpMethod.PUT, ignoreWebSecurityProperties.getPut()).antMatchers(HttpMethod.HEAD, ignoreWebSecurityProperties.getHead()).antMatchers(HttpMethod.PATCH, ignoreWebSecurityProperties.getPatch()).antMatchers(HttpMethod.OPTIONS, ignoreWebSecurityProperties.getOptions()).antMatchers(HttpMethod.TRACE, ignoreWebSecurityProperties.getTrace()).antMatchers(ignoreWebSecurityProperties.getPattern());}}

改造HelloController

  1. /**
  2.  * @author changjin wei(魏昌进)
  3.  * @since 2022/12/15
  4.  */@RestController@RequestMapping("hello")publicclassHelloController{/** 测试PathVariable参数 */@GetMapping("/properties")@IgnoreWebSecuritypublicStringproperties(){return"Hello, properties";}/** 测试PathVariable参数 */@GetMapping("/{path}/properties")@IgnoreWebSecuritypublicStringpropertiesPath(@PathVariableString path){return"Hello, properties. path: "+ path;}}

application.yml

  1. security:ignoring:get:- /hello/{path}/properties

测试结果

  1. # 配置文件测试curl http://127.0.0.1:8080/hello/properties -i
  2. HTTP/1.1 200 
  3. Content-Type: text/plain;charset=UTF-8
  4. Content-Length: 17
  5. Date: Sun, 18 Dec 202212:35:14 GMT
  7. Hello, properties
  9. # 配置文件测试curl http://127.0.0.1:8080/hello/public_api/properties -i
  10. HTTP/1.1 200 
  11. Content-Type: text/plain;charset=UTF-8
  12. Content-Length: 35
  13. Date: Sun, 18 Dec 202212:36:01 GMT
  15. Hello, properties. path: public_api

总结

其实无论是介于注解方式还是配置文件方式都各有优缺点看大家是否的选择了，通过这种方式可以减少代码硬编码的问题。
