SpringSecurity和Shiro是两大权限框架，前者属于Spring家族，功能比较强，重量级的存在，新手搞的时候可能会经常遇到坑。后者比较轻量级，上手相对比较简单。这两个我都写过权限管理的博客。

前填有个朋友让我帮他把他的一个 SpringSecurity 项目改造成通过URL检查权限，之前他在控制器每个方法上加上如下注解来实现的，该方法通常是初学者使用的，但是用于公司的大型项目肯定不行，比较蠢，代码冗余，不能扩展，不利于维护。
  1. @PreAuthorize("hasAnyAuthority('ROLE_ADMIN'")  // 指定角色权限才能操作方法

现在的目标就是剔除所有的该注解，通过拦截器来判断该用户是否有该URL的权限。

在这之前先讲一下Spring Security实现权限管理吧！


一、数据库设计


主要包括用户表，角色表，权限表，用户和角色关联表，角色和权限关联表

重要字段我都用红线标明了

其中权限表(t_permission)其实也充当了菜单表的作用，其中的path字段就是请求路径，如 /post，/psot/new，/post/edit/* （我们以正则表达式的方式写，后面不限字符串以*表示），到时候比对的时候用正则表达式判断







实体类这里就不给了，这里主要还是讲核心思想

主要关注第二节的配置


二、核心文件


1.SpringSecurity的配置文件

WebSecurityConfig.java
  1. package com.liuyanzhao.sens.config.security;
  3. import com.liuyanzhao.sens.common.utils.SecurityUtil;
  4. import com.liuyanzhao.sens.config.security.jwt.AuthenticationFailHandler;

  18. import org.springframework.security.config.annotation.web.configurers.ExpressionUrlAuthorizationConfigurer;
  19. import org.springframework.security.config.http.SessionCreationPolicy;
  20. import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
  21. import org.springframework.security.web.access.intercept.FilterSecurityInterceptor;
  23. /**

  28. @Slf4j
  29. @Configuration
  30. @EnableGlobalMethodSecurity(prePostEnabled=true)
  31. public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

  51.     @Autowired

  54.     @Autowired
  55.     private SecurityUtil securityUtil;
  57.     @Override

  60.     }
  62.     @Override
  63.     protected void configure(HttpSecurity http) throws Exception {
  65.         ExpressionUrlAuthorizationConfigurer<HttpSecurity>.ExpressionInterceptUrlRegistry registry = http
  66.                 .authorizeRequests();
  68.         //除配置文件忽略路径其它所有请求都需经过认证和授权
  69.         for(String url:ignoredUrlsProperties.getUrls()){
  70.             registry.antMatchers(url).permitAll();
  71.         }
  73.         registry.and()
  74.                 //表单登录方式
  75.                 .formLogin()

  84.                 .and()
  85.                 //允许网页iframe
  86.                 .headers().frameOptions().disable()

  99.                 //前后端分离采用JWT 不需要session

  101.                 .and()
  102.                 //自定义权限拒绝处理类
  103.                 .exceptionHandling().accessDeniedHandler(accessDeniedHandler)
  104.                 .and() //添加自定义权限过滤器
  105.                 .addFilterBefore(myFilterSecurityInterceptor, FilterSecurityInterceptor.class);
  106.     }
  107. }

addFilterBefore 作用就是当执行权限验证前执行，我们需要在这之前判断即可。



2.自定义拦截器

  29.         super.setAccessDecisionManager(myAccessDecisionManager);
  30.     }
  32.     @Override

  41.         invoke(fi);
  42.     }
  44.     public void invoke(FilterInvocation fi) throws IOException, ServletException {
  46.         InterceptorStatusToken token = super.beforeInvocation(fi);
  47.         try {
  48.             fi.getChain().doFilter(fi.getRequest(), fi.getResponse());
  49.         } finally {
  50.             super.afterInvocation(token, null);
  51.         }
  52.     }
  54.     @Override
  55.     public void destroy() {
  57.     }
  59.     @Override

3.自定义权限资源管理器

4.自定义角色决断器

MyAccessDecisionManager.java

四、匿名访问的URL通过application.yml配置


上面 WebSecurityConfig 中我们通过读取 application.yml 中的配置，允许匿名访问这些路径。

公司通常也是这样做的。
