之前介绍了springboot使用security进行权限管理，这篇文件介绍一下springboot使用shiro进行安全管理。

简述本文的场景，本文使用springboot1.5.9+mysql+jpa+thymeleaf+shiro制作一个简单的验证，其中有2个角色，分别是admin和user，admin可以使用select和delete功能，user只能使用select功能。

新建项目，加入shiro依赖，pom文件如下：

配置文件如下：

##端口号
server.port=8888



##数据库配置
##数据库地址
spring.datasource.url=jdbc:mysql://localhost:3306/shiro?characterEncoding=utf8&useSSL=false
##数据库用户名
spring.datasource.username=root
##数据库密码
spring.datasource.password=root
##数据库驱动
spring.datasource.driver-class-name=com.mysql.jdbc.Driver


##validate  加载hibernate时，验证创建数据库表结构
##create   每次加载hibernate，重新创建数据库表结构，这就是导致数据库表数据丢失的原因。
##create-drop        加载hibernate时创建，退出是删除表结构
##update                 加载hibernate自动更新数据库结构
##validate 启动时验证表的结构，不会创建表
##none  启动时不做任何操作
spring.jpa.hibernate.ddl-auto=update

##控制台打印sql
spring.jpa.show-sql=true


# 建议在开发时关闭缓存,不然没法看到实时页面
spring.thymeleaf.cache=false
##去除thymeleaf的html严格校验
spring.thymeleaf.mode=LEGACYHTML5

创建了三个实体类，分别是
SysUser（用户表）

package com.dalaoyang.entity;

import org.hibernate.validator.constraints.NotEmpty;

import javax.persistence.*;
import java.io.Serializable;
import java.util.List;

/**

 */
@Entity
public class SysUser implements Serializable {

    @Id
    @GeneratedValue
    private Integer userId;
    @NotEmpty
    private String userName;
    @NotEmpty
    private String passWord;

    //多对多关系
    @ManyToMany(fetch= FetchType.EAGER)
    //急加载，加载一个实体时，定义急加载的属性会立即从数据库中加载
    //FetchType.LAZY：懒加载，加载一个实体时，定义懒加载的属性不会马上从数据库中加载
    @JoinTable(name = "SysUserRole", joinColumns = { @JoinColumn(name = "userId") },
            inverseJoinColumns ={@JoinColumn(name = "roleId") })
    private List<SysRole> roleList;// 一个用户具有多个角色


    public Integer getUserId() {
        return userId;
    }

    public void setUserId(Integer userId) {
        this.userId = userId;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassWord() {
        return passWord;
    }

    public void setPassWord(String passWord) {
        this.passWord = passWord;
    }

    public List<SysRole> getRoleList() {
        return roleList;
    }

    public void setRoleList(List<SysRole> roleList) {
        this.roleList = roleList;
    }
}

SysRole（角色表）

package com.dalaoyang.entity;

import org.hibernate.validator.constraints.NotEmpty;

import javax.persistence.*;
import java.io.Serializable;
import java.util.List;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn

 * @date 2018/5/2
 */
@Entity
public class SysRole implements Serializable {

    @Id
    @GeneratedValue
    private Integer roleId;
    private String roleName;

    //多对多关系
    @ManyToMany(fetch= FetchType.EAGER)
    @JoinTable(name="SysRoleMenu",joinColumns={@JoinColumn(name="roleId")},inverseJoinColumns={@JoinColumn(name="menuId")})
    private List<SysMenu> menuList;

    //多对多关系
    @ManyToMany
    @JoinTable(name="SysUserRole",joinColumns={@JoinColumn(name="roleId")},inverseJoinColumns={@JoinColumn(name="userId")})
    private List<SysUser> userList;// 一个角色对应多个用户

    public Integer getRoleId() {
        return roleId;
    }

    public void setRoleId(Integer roleId) {
        this.roleId = roleId;
    }

    public String getRoleName() {
        return roleName;
    }

    public void setRoleName(String roleName) {
        this.roleName = roleName;
    }

    public List<SysMenu> getMenuList() {
        return menuList;
    }

    public void setMenuList(List<SysMenu> menuList) {
        this.menuList = menuList;
    }

    public List<SysUser> getUserList() {
        return userList;
    }

    public void setUserList(List<SysUser> userList) {
        this.userList = userList;
    }
}

SysMenu（菜单表）

package com.dalaoyang.entity;

import javax.persistence.*;
import java.io.Serializable;
import java.util.List;

/**

@Entity
public class SysMenu implements Serializable {

    @Id
    @GeneratedValue
    private Integer menuId;
    private String menuName;

    @ManyToMany
    @JoinTable(name="SysRoleMenu",joinColumns={@JoinColumn(name="menuId")},inverseJoinColumns={@JoinColumn(name="roleId")})
    private List<SysRole> roleList;

    public Integer getMenuId() {
        return menuId;
    }

    public void setMenuId(Integer menuId) {
        this.menuId = menuId;
    }

    public String getMenuName() {
        return menuName;
    }

    public void setMenuName(String menuName) {
        this.menuName = menuName;
    }

    public List<SysRole> getRoleList() {
        return roleList;
    }

    public void setRoleList(List<SysRole> roleList) {
        this.roleList = roleList;
    }
}

创建一个UserRepository用于查询用户信息：

package com.dalaoyang.repository;

import com.dalaoyang.entity.SysUser;
import org.springframework.data.repository.CrudRepository;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.repository
 * @email yangyang@dalaoyang.cn
 * @date 2018/5/2
 */
public interface UserRepository extends CrudRepository<SysUser,Long> {

    SysUser findByUserName(String username);
}

创建几个前台页面进行测试，分别是：
login.html:

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
</head>
<body>
错误信息：<h4 th:text="${msg}"></h4>
<form action="" method="post">
    <p>账号：<input type="text" name="username" value="dalaoyang"/></p>
    <p>密码：<input type="text" name="password" value="123"/></p>
    <p><input type="submit" value="登录"/></p>
</form>
</body>
</html>

index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
index
<br/>
<form th:action="@{/logout}" method="post">
    <p><input type="submit" value="注销"/></p>
</form>
</body>
</html>

delete.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
delete
</body>
</html>

select.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
select
</body>
</html>

403.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
403
</body>
</html>

创建一个ShiroConfig，代码如下：

package com.dalaoyang.config;

import org.apache.shiro.mgt.SecurityManager;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.handler.SimpleMappingExceptionResolver;

import java.util.Date;
import java.util.LinkedHashMap;
import java.util.Map;
import java.util.Properties;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.config
 * @email yangyang@dalaoyang.cn
 * @date 2018/5/2
 */
@Configuration
public class ShiroConfig {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    @Bean
    public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager) {
        logger.info("启动shiroFilter--时间是：" + new Date());
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager);
        //shiro拦截器
        Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String,String>();
        //<!-- authc:所有url都必须认证通过才可以访问; anon:所有url都都可以匿名访问-->
        //<!-- 过滤链定义，从上向下顺序执行，一般将/**放在最为下边 -->

        // 配置不被拦截的资源及链接
        filterChainDefinitionMap.put("/static/**", "anon");
        // 退出过滤器
        filterChainDefinitionMap.put("/logout", "logout");

        //配置需要认证权限的
        filterChainDefinitionMap.put("/**", "authc");
        // 如果不设置默认会自动寻找Web工程根目录下的"/login"页面，即本文使用的login.html
        shiroFilterFactoryBean.setLoginUrl("/login");
        // 登录成功后要跳转的链接
        shiroFilterFactoryBean.setSuccessUrl("/index");

        //未授权界面
        shiroFilterFactoryBean.setUnauthorizedUrl("/403");
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return shiroFilterFactoryBean;
    }

    //自定义身份认证Realm（包含用户名密码校验，权限校验等）
    @Bean
    public MyShiroRealm myShiroRealm(){
        MyShiroRealm myShiroRealm = new MyShiroRealm();
        return myShiroRealm;
    }


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

    //开启shiro aop注解支持，不开启的话权限验证就会失效
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(SecurityManager securityManager){
        AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor();
        authorizationAttributeSourceAdvisor.setSecurityManager(securityManager);
        return authorizationAttributeSourceAdvisor;
    }

    //配置异常处理，不配置的话没有权限后台报错，前台不会跳转到403页面
    @Bean(name="simpleMappingExceptionResolver")
    public SimpleMappingExceptionResolver
    createSimpleMappingExceptionResolver() {
        SimpleMappingExceptionResolver simpleMappingExceptionResolver = new SimpleMappingExceptionResolver();
        Properties mappings = new Properties();
        mappings.setProperty("DatabaseException", "databaseError");//数据库异常处理
        mappings.setProperty("UnauthorizedException","403");
        simpleMappingExceptionResolver.setExceptionMappings(mappings);  // None by default
        simpleMappingExceptionResolver.setDefaultErrorView("error");    // No default
        simpleMappingExceptionResolver.setExceptionAttribute("ex");     // Default is "exception"
        return simpleMappingExceptionResolver;
    }
}

在配置一个MyShiroRealm用于登录认证和授权认证，代码如下：

package com.dalaoyang.config;

import com.dalaoyang.entity.SysMenu;
import com.dalaoyang.entity.SysRole;
import com.dalaoyang.entity.SysUser;
import com.dalaoyang.repository.UserRepository;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
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 javax.annotation.Resource;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.config
 * @email yangyang@dalaoyang.cn
 * @date 2018/5/2
 */
public class MyShiroRealm extends AuthorizingRealm {

    @Resource
    private UserRepository userRepository;

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
        SysUser userInfo  = (SysUser)principals.getPrimaryPrincipal();
        for(SysRole role:userInfo.getRoleList()){
            authorizationInfo.addRole(role.getRoleName());
            for(SysMenu menu:role.getMenuList()){
                authorizationInfo.addStringPermission(menu.getMenuName());
            }
        }
        return authorizationInfo;
    }

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token)
            throws AuthenticationException {
        //获得当前用户的用户名
        String username = (String)token.getPrincipal();
        System.out.println(token.getCredentials());
        //根据用户名找到对象
        //实际项目中，这里可以根据实际情况做缓存，如果不做，Shiro自己也是有时间间隔机制，2分钟内不会重复执行该方法
        SysUser userInfo = userRepository.findByUserName(username);
        if(userInfo == null){
            return null;
        }
        //这里会去校验密码是否正确
        SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
                userInfo, //用户名
                userInfo.getPassWord(),//密码
                getName()
        );
        return authenticationInfo;
    }
}

最后新建一个controller，其中本文使用了2种验证权限的方法，select方法使用@RequiresPermissions("select")来验证用户是否具有select权限，delete方法使用@RequiresRoles("admin")来验证用户是否是admin，代码如下：

package com.dalaoyang.controller;

import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authz.annotation.RequiresPermissions;
import org.apache.shiro.authz.annotation.RequiresRoles;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import java.util.Map;

/**
 * @author dalaoyang
 * @Description
 * @project springboot_learn
 * @package com.dalaoyang.controller
 * @email yangyang@dalaoyang.cn
 * @date 2018/5/2
 */
@Controller
public class TestController {

    @GetMapping({"/","/index"})
    public String index(){
        return"index";
    }

    @GetMapping("/403")
    public String unauthorizedRole(){
        return "403";
    }

    @GetMapping("/delete")
    //@RequiresPermissions("delete")
    @RequiresRoles("admin")
    public String delete(){
        return "delete";
    }

    @GetMapping("/select")
    @RequiresPermissions("select")
    public String select(){
        return "select";
    }

    @RequestMapping("/login")
    public String login(HttpServletRequest request, Map<String, Object> map) throws Exception{
        System.out.println("HomeController.login()");
        // 登录失败从request中获取shiro处理的异常信息。
        // shiroLoginFailure:就是shiro异常类的全类名.
        String exception = (String) request.getAttribute("shiroLoginFailure");
        String msg = "";
        //根据异常判断错误类型
        if (exception != null) {
            if (UnknownAccountException.class.getName().equals(exception)) {
                msg = "账号不存在";
            } else if (IncorrectCredentialsException.class.getName().equals(exception)) {
                msg = "密码不正确";
            } else {
                msg = "else >> "+exception;
            }
        }
        map.put("msg", msg);
        // 此方法不处理登录成功,由shiro进行处理
        return "/login";
    }

    @GetMapping("/logout")
    public String logout(){
        return "/login";
    }
}

为了方便测试，本人插入了几条初始数据，sql如下：

INSERT INTO `shiro`.`sys_menu`(`menu_id`, `menu_name`) VALUES (1, 'add');
INSERT INTO `shiro`.`sys_menu`(`menu_id`, `menu_name`) VALUES (2, 'delete');
INSERT INTO `shiro`.`sys_menu`(`menu_id`, `menu_name`) VALUES (3, 'update');
INSERT INTO `shiro`.`sys_menu`(`menu_id`, `menu_name`) VALUES (4, 'select');
INSERT INTO `shiro`.`sys_role`(`role_id`, `role_name`) VALUES (1, 'admin');
INSERT INTO `shiro`.`sys_role`(`role_id`, `role_name`) VALUES (2, 'user');
INSERT INTO `shiro`.`sys_role_menu`(`role_id`, `menu_id`) VALUES (1, 1);
INSERT INTO `shiro`.`sys_role_menu`(`role_id`, `menu_id`) VALUES (1, 2);
INSERT INTO `shiro`.`sys_role_menu`(`role_id`, `menu_id`) VALUES (1, 3);
INSERT INTO `shiro`.`sys_role_menu`(`role_id`, `menu_id`) VALUES (1, 4);
INSERT INTO `shiro`.`sys_role_menu`(`role_id`, `menu_id`) VALUES (2, 4);
INSERT INTO `shiro`.`sys_user`(`user_id`, `pass_word`, `user_name`) VALUES (1, '123', 'dalaoyang');
INSERT INTO `shiro`.`sys_user`(`user_id`, `pass_word`, `user_name`) VALUES (2, '123', 'xiaoli');
INSERT INTO `shiro`.`sys_user_role`(`role_id`, `user_id`) VALUES (1, 1);
INSERT INTO `shiro`.`sys_user_role`(`role_id`, `user_id`) VALUES (2, 2);

启动项目，我在这里就不一一截图了，口述一下，访问http://localhost:8888/select由于没有登录的原因，会自动跳转到http://localhost:8888/login，输入错误的用户名和密码会出现对应的提示。输入角色user的用户名xiaoli，密码123。访问http://localhost:8888/select页面会正常跳转，访问http://localhost:8888/delete会拦截到403页面。

如果使用角色为admin的用户dalaoyang密码123登录，以上请求全可以正常访问。
