shiro 的基本使用

1. maven 依赖的引入

 <dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-core</artifactId>
    <version>1.4.0</version>
</dependency>
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.4.0</version>
</dependency>

2. shiro 的配置

#### 1. SecurityManager 的配置

@Bean
public SecurityManager securityManager( ) {
   DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
   securityManager.setRealm(myShiroRealm());
   return securityManager;
}

2 myShiroRealm的配置

@Bean
public MyShiroRealm myShiroRealm() {
   MyShiroRealm myShiroRealm = new MyShiroRealm();
   return myShiroRealm;
}

 public class MyShiroRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
  User user = ((User) principalCollection.getPrimaryPrincipal());
        System.out.println(user);
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
        //添加角色
        simpleAuthorizationInfo.addRole(user.getUsername());
        //添加权限
        simpleAuthorizationInfo.addStringPermission("create");
        return simpleAuthorizationInfo;
    }
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        String username = token.getUsername();
        char[] password = token.getPassword();
        User user = ...; //  查询数据库
        System.out.println(user.getUsername());
        SimpleAuthenticationInfo simpleAuthenticationInfo =
                new SimpleAuthenticationInfo(user, user.getPassword(), getName());
        return simpleAuthenticationInfo;
    }
     

3. Filter工厂的配置

  //Filter工厂，设置对应的过滤条件和跳转条件
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(SecurityManager securityManager) {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        Map<String,String> map = new HashMap<String, String>();
        //登出
        map.put("/logout","logout");
        map.put("/doLogin", "anon");//对所有用户认证
        map.put("/**","authc");
        //登录
        shiroFilterFactoryBean.setLoginUrl("/login.html");
        //首页
        shiroFilterFactoryBean.setSuccessUrl("/index");
        //错误页面，认证不通过跳转
        shiroFilterFactoryBean.setUnauthorizedUrl("/error");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(map);
        return shiroFilterFactoryBean;
    }

4. @RequiresRoles @RequiresPermissions 注解的配置

@Bean
public DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator(){
    DefaultAdvisorAutoProxyCreator advisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator();
    advisorAutoProxyCreator.setProxyTargetClass(true);
    return advisorAutoProxyCreator;
}
@Bean
public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager) {
    AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
    authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
    return authorizationAttributeSourceAdvisor;
}
