ssm框架与shiro的整合小demo，用idea开发+maven管理

shiro安全框架是目前为止作为登录注册最常用的框架，因为它十分的强大简单，提供了认证、授权、加密和会话管理等功能 。

　　shiro能做什么？

　　　　　　　认证：验证用户的身份

　　　　　　　授权：对用户执行访问控制：判断用户是否被允许做某事

　　　　　　　会话管理：在任何环境下使用 Session API，即使没有 Web 或EJB 容器。

　　　　　　　加密：以更简洁易用的方式使用加密功能，保护或隐藏数据防止被偷窥

　　　　　　　Realms：聚集一个或多个用户安全数据的数据源

　　　　　　　单点登录（SSO）功能。

　　　　　　　为没有关联到登录的用户启用 "Remember Me“ 服务

　　Shiro 的四大核心部分

　　　　　　Authentication(身份验证)：简称为“登录”，即证明用户是谁。

　　　　　　Authorization(授权)：访问控制的过程，即决定是否有权限去访问受保护的资源。

　　　　　　Session Management(会话管理)：管理用户特定的会话，即使在非 Web 或 EJB 应用程序。

　　　　　　Cryptography(加密)：通过使用加密算法保持数据安全

　　shiro的三个核心组件：　　　　　

　　　　　　Subject ：正与系统进行交互的人，或某一个第三方服务。所有 Subject 实例都被绑定到（且这是必须的）一个SecurityManager 上。

　　　　　　SecurityManager：Shiro 架构的心脏，用来协调内部各安全组件，管理内部组件实例，并通过它来提供安全管理的各种服务。当 Shiro 与一个 Subject 进行交互时，实质上是幕后的 SecurityManager 处理所有繁重的 Subject 安全操作。

　　　　　　Realms ：本质上是一个特定安全的 DAO。当配置 Shiro 时，必须指定至少一个 Realm 用来进行身份验证和/或授权。Shiro 提供了多种可用的 Realms 来获取安全相关的数据。如关系数据库(JDBC)，INI 及属性文件等。可以定义自己 Realm 实现来代表自定义的数据源。

到这一步，配置文件都基本准备好了，接下来要写Realm方法了，新建realm包，在包下新建MyRealm.java文件继承AuthorizingRealm

package com.xingshang.realm;

import com.xingshang.dao.UserDao;
import com.xingshang.entity.User;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.springframework.beans.factory.annotation.Autowired;
import org.apache.shiro.util.ByteSource.Util;

import java.util.HashSet;
import java.util.List;
import java.util.Set;

public class MyRealm extends AuthorizingRealm {

    @Autowired
    private UserDao userDao;

    /**
     * 1、登入认证
     * thenticationInfo：获取认证消息，如果数据库中没有，返回null，如果得到正确的用户名和密码
     * 2、AuthenticationInfo  可用simpleAuthenticationInfo实现类，封装获取到的正确的账号和密码
     * 返回正定类型的对象
     *
     * @param authenticationToken
     * @return
     * @throws AuthenticationException
     */
    protected SimpleAuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        //1、将token转换为UserNamePasswordToken
        UsernamePasswordToken uptoken = (UsernamePasswordToken) authenticationToken;

        //2、获取用户名
        User user = new User();
        user.setUsername(uptoken.getUsername());
        user.setPassword(uptoken.getPassword().toString());

        User us = userDao.login(user);
        if (us != null) {
            SimpleAuthenticationInfo authenticationInfo
                    = new SimpleAuthenticationInfo(us.getUsername(), us.getPassword(), "a");
            authenticationInfo.setCredentialsSalt(Util.bytes(us.getSalt()));
            return authenticationInfo;
        } else {
            throw new ExcessiveAttemptsException("账号密码错误");
        }
    }

    /**
     * 权限角色认证
     *
     * @param principalCollection
     * @return
     */
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        String username = principalCollection.getPrimaryPrincipal().toString();

        List<String> roles = userDao.selectRole(username);
        List<String> permissions = userDao.selectPermission(username);

        Set<String> ro = new HashSet<String>();
        Set<String> per = new HashSet<String>();

        for (String role : roles) {
            ro.add(role);
        }
        for (String permission : permissions) {
            per.add(permission);
        }

        SimpleAuthorizationInfo sim = new SimpleAuthorizationInfo();
        sim.setRoles(ro);
        sim.setStringPermissions(per);

        return sim;
    }
}

好了，接下来我们写一个简单的controller来通过shiro登录验证。

package com.xingshang.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class LoginController {

    @RequestMapping("/login")
    public String login(@RequestParam("username") String username,@RequestParam("password") String password){
        Subject subject = SecurityUtils.getSubject();
        if (!subject.isAuthenticated()){
            UsernamePasswordToken token = new UsernamePasswordToken(username,password);
            try {
　　　　　　　　　　//执行认证操作
                subject.login(token);
            }catch (Exception e){
                return e.getMessage();
            }
        }
        return "success";
    }

    @RequestMapping("/test1")
    @ResponseBody
    public String test1(){
        Subject subject = SecurityUtils.getSubject();
        try {
            subject.checkRole("admin");
        }catch (Exception e){
            return "不拥有admin角色";
        }
        return "拥有admin角色";
    }

    @RequestMapping("/test2")
    @ResponseBody
    public String test2(){
        Subject subject= SecurityUtils.getSubject();
        try {
            subject.checkRole("CEO");
        }catch (Exception e){
            return "不拥有CEO角色";
        }
        return "拥有admin角色";
    }
}
