2、测试

public void test() {
    //连接druid数据池
    DruidDataSource dataSource=new DruidDataSource();
    dataSource.setUrl("jdbc:mysql://localhost:3306/shiro?characterEncoding=utf8");
    dataSource.setUsername("root");
    dataSource.setPassword("240010");

    //自定义realm放入数据池并设置权限查找
    JdbcRealm jdbcRealm=new JdbcRealm();
    jdbcRealm.setPermissionsLookupEnabled(true);
    jdbcRealm.setDataSource(dataSource);

    //securityManager获取并设置realm
    DefaultSecurityManager defaultSecurityManager=new DefaultSecurityManager();
    defaultSecurityManager.setRealm(jdbcRealm);
    SecurityUtils.setSecurityManager(defaultSecurityManager);

    //getSubject和获取token
    Subject ssub = SecurityUtils.getSubject();
    UsernamePasswordToken toke = new UsernamePasswordToken("zhangsan", "123");

    //使用login方法登陆   使用isAuthenticated验证  使用isPermitted看授权
    try {
        ssub.login(toke);
        if(ssub.isAuthenticated()){
            System.out.println("成功");
        }
        if(ssub.isPermitted("userList")){
            System.out.println("有userList权限");
        }else{
            System.out.println("没有这个userList权限");
        }
    } catch (UnknownAccountException uae) {
        System.out.println(uae.getMessage());
        uae.printStackTrace();
    } catch (IncorrectCredentialsException ice) {
        System.out.println(ice.getMessage());
        ice.printStackTrace();
    }
}
