shiro （java安全框架）
Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。
主要功能
三个核心组件：Subject, SecurityManager 和 Realms.
Subject
：即“当前操作用户”。但是，在Shiro中，Subject这一概念并不仅仅指人，也可以是第三方进程、后台帐户（Daemon Account）或其他类似事物。它仅仅意味着“当前跟软件交互的东西”。
Subject代表了当前用户的安全操作，SecurityManager则管理所有用户的安全操作。
SecurityManager
：它是Shiro框架的核心，典型的Facade模式，Shiro通过SecurityManager来管理内部组件实例，并通过它来提供安全管理的各种服务。
Realm：
Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说，当对用户执行认证（登录）和授权（访问控制）验证时，Shiro会从应用配置的Realm中查找用户及其权限信息。
从这个意义上讲，Realm实质上是一个安全相关的DAO：它封装了数据源的连接细节，并在需要时将相关数据提供给Shiro。当配置Shiro时，你必须至少指定一个Realm，用于认证和（或）授权。配置多个Realm是可以的，但是至少需要一个。
Shiro内置了可以连接大量安全数据源（又名目录）的Realm，如LDAP、关系数据库（JDBC）、类似INI的文本配置资源以及属性文件等。如果缺省的Realm不能满足需求，你还可以插入代表自定义数据源的自己的Realm实现。

数据库建表：
数据库有用户（user）、角色（role）、权限（permission）三个实体，除了实体表以外，为了实现表间用户与角色、角色与权限多对多的表间关系，所以产生了user_role、role_permission两张关系表。在下图中，使用红线将表的外键标记了出来，但为了方便并没有在表中创建外键，我们手动进行维护。
参考：
user：
role：
permission：
user_role:
role_permission:
编写sql语句：根据用户id查询出对应的权限：
SELECT DISTINCT
*
FROM
permission
WHERE
id IN (
SELECT
rp.pid
FROM
USER u
LEFT JOIN user_role ur ON u.id = ur.uid
LEFT JOIN role_permission rp ON ur.rid = rp.rid
WHERE
u.id = 1
)
结果：
生成实体类，mapper，mapperxml：
package com.liuxi.entity;
public class User {
private Integer id;
private String username;
private String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username == null ? null : username.trim();

this.password = password == null ? null : password.trim();

IndexController编写登陆登出等等逻辑和权限控制
package com.liuxi.controller;

import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpSession;
@Controller
public class IndexController {
@RequestMapping("index")
public String index(){
System.out.println(666);
return "index";
}
@RequestMapping("login")
public String login(String user, String pwd, ModelMap map, HttpSession session) throws Exception {

try {

User user2 = (User) subject.getPrincipal();
session.setAttribute("user", user2);
return "redirect:/";
} catch (Exception e) {
return "login";// 返回登录页面
}
}
@RequestMapping("/logout")
public String logout(HttpSession session) {

}
@RequestMapping("toLogin")
public String toLogin(){

@RequiresPermissions("/insert") // @RequiresPermissions("添加权限的url")使用来添加权限的
@RequestMapping("insert")
