     </dependency>
     </dependencies>

**3、**application.properties

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
    spring.datasource.driver-class-name=com.mysql.jdbc.Driver
    spring.datasource.url=jdbc:mysql:///#
    spring.datasource.username=#
    spring.datasource.password=#
    ## mybatis ##
    mybatis.mapper-locations=mappers/*.xml
    mybatis.type-aliases-package=com.zhu.shiro.entity
    ## 视图解析器 ##
    spring.mvc.view.prefix=/pages/
    spring.mvc.view.suffix=.jsp

三、项目设计

**注: **spring整合shiro中是只有User实体类，在UserDao中定义了三个方法，通过表的关键关系查询Role和Permission;这里将采用另一种方式，三个实体类，设置实体类的关联关系。

**1、**entity层

User.java

public class User {
     private Integer uid;
     private String username;
     private String password;
     private Set<Role> roles = new HashSet<>();
    }

Role.java

public class Role {
     private Integer rid;
     private String name;
     private Set<Permission> permissions = new HashSet<>();
    }

Permission.java

public class Permission {
     private Integer pid;
     private String name;
    }

**2、**dao层

UserDao.java

public interface UserDao {
     User findByUsername(String username);
    }

UserDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE mapper
     PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
     "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="com.zhu.shiro.dao.UserDao">
     <resultMap id="userMap" type="com.zhu.shiro.entity.User">
      <id property="uid" column="uid"/>
      <result property="username" column="user_name"/>
      <result property="password" column="pass_word"/>
     <collection property="roles" ofType="com.zhu.shiro.entity.Role">
      <id property="rid" column="rid"/>
      <result property="name" column="role_name"/>
     <collection property="permissions" ofType="com.zhu.shiro.entity.Permission">
      <id property="pid" column="pid"/>
      <result property="name" column="permission_name"/>
     </collection>
     </collection>
     </resultMap>
     <select id="findByUsername" parameterType="string" resultMap="userMap">
     SELECT *
     FROM tb_user u,tb_role r,tb_permission p
     WHERE u.rid=r.rid
     AND p.rid=r.rid
     AND u.user_name=#{username}
     </select>
     
    </mapper>

**3、**service层

@Service
    public class UserServiceImpl implements UserService {
     @Autowired
     private UserDao userDao;
     @Override
     public User findByUsername(String username) {
     return userDao.findByUsername(username);
     }
    }

**4、**junit测试

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class UserServiceImplTest {
     @Autowired
     private UserService userService;
     @Test
     public void findByUsername() {
     User u = userService.findByUsername("tom");
     Set<Role> roleSet = u.getRoles();
     for (Role role : roleSet){
     Set<Permission> permissionSet = role.getPermissions();
     for (Permission permission : permissionSet){
     System.out.println(permission.getName());
     }
     System.out.println(role.getName());
     }
     }
    }

*运行结果:*

数据库中tom是admin角色，有增删改查权限，符合预期，测试通过。

**5、**controller层

TestController.java

@Controller
    public class TestController {
     //用户登录
     @RequestMapping("/loginUser")
     public String loginUser(@RequestParam("username") String username,
     @RequestParam("password") String password,
     HttpSession session) {
     //把前端输入的username和password封装为token
     UsernamePasswordToken token = new UsernamePasswordToken(username, password);
     Subject subject = SecurityUtils.getSubject();
     try {
     subject.login(token);
     session.setAttribute("user", subject.getPrincipal());
     return "index";
     } catch (Exception e) {
     return "login";
     }
     }
     //退出登录
     @RequestMapping("/logout")
     public String logout() {
     Subject subject = SecurityUtils.getSubject();
     if (subject != null) {
     subject.logout();
     }
     return "login";
     }
     //访问login时跳到login.jsp
     @RequestMapping("/login")
     public String login() {
     return "login";
     }
     //admin角色才能访问
     @RequestMapping("/admin")
     @ResponseBody
     public String admin() {
     return "admin success";
     }
     //有delete权限才能访问
     @RequestMapping("/edit")
     @ResponseBody
     public String edit() {
     return "edit success";
     }
     @RequestMapping("/test")
     @ResponseBody
     @RequiresRoles("guest")
     public String test(){
     return "test success";
     }
    }

**说明:**这里用户登录方法用到了shiro，但是这里还没配置shiro，所以暂时不能使用，先搭起整个骨架，然后再加入shiro。

**6、**jsp页面

(登录页面)

%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
     <title>Login</title>
    </head>
    <body>
     <h1>欢迎登录！</h1>
     <form action="/loginUser" method="post">
     <input type="text" name="username"><br>
     <input type="password" name="password"><br>
     <input type="submit" value="提交">
     </form>
    </body>
    </html>

index.jsp

(登录成功跳转的页面)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
     <title>Title</title>
    </head>
    <body>
     <h1>欢迎登录，${user.username}</h1>
    </body>
    </html>

unauthorized.jsp

(无权访问跳转的页面)

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
     <title>unauthorized</title>
    </head>
    <body>
    unauthorized!
    </body>
    </html>

**现在说一下要求:**

admin路由要求只有具有admin角色的用户才能访问，edit路由需要有delete权限的用户才能访问，test路由要guest角色才能访问，login、loginUser都不做拦截，本文讲解两种拦截方式，对test的拦截是在controller对应的方法上加注解，其他是拦截是写在shiro的配置类中。

**预期分析:**

tom是有admin角色和所有权限，所以用tom登录后，可以访问edit和admin，但是不能访问guest;

而cat是guest角色，只有create和query权限，所以不能访问admin和edit，但是可以访问guest。

四、配置shiro

由于springboot还没有集成shiro，所以不能直接在application.properties中配置，需要通过类的方式配置。

核心配置类:

ShiroConfiguration.java

@Configuration
    public class ShiroConfiguration {
     /**
     * 密码校验规则HashedCredentialsMatcher
     * 这个类是为了对密码进行编码的 ,
     * 防止密码在数据库里明码保存 , 当然在登陆认证的时候 ,
     * 这个类也负责对form里输入的密码进行编码
     * 处理认证匹配处理器：如果自定义需要实现继承HashedCredentialsMatcher
     */
     @Bean("hashedCredentialsMatcher")
     public HashedCredentialsMatcher hashedCredentialsMatcher() {
     HashedCredentialsMatcher credentialsMatcher = new HashedCredentialsMatcher();
     //指定加密方式为MD5
     credentialsMatcher.setHashAlgorithmName("MD5");
     //加密次数
     credentialsMatcher.setHashIterations(1024);
     credentialsMatcher.setStoredCredentialsHexEncoded(true);
     return credentialsMatcher;
     }
     @Bean("authRealm")
     @DependsOn("lifecycleBeanPostProcessor")//可选
     public AuthRealm authRealm(@Qualifier("hashedCredentialsMatcher") HashedCredentialsMatcher matcher) {
     AuthRealm authRealm = new AuthRealm();
     authRealm.setAuthorizationCachingEnabled(false);
     authRealm.setCredentialsMatcher(matcher);
     return authRealm;
     }
     /**
     * 定义安全管理器securityManager,注入自定义的realm
     * @param authRealm
     * @return
     */
     @Bean("securityManager")
     public SecurityManager securityManager(@Qualifier("authRealm") AuthRealm authRealm) {
     DefaultWebSecurityManager manager = new DefaultWebSecurityManager();
     manager.setRealm(authRealm);
     return manager;
     }
     /**
     * 定义shiroFilter过滤器并注入securityManager
     * @param manager
     * @return
     */
     @Bean("shiroFilter")
     public ShiroFilterFactoryBean shiroFilter(@Qualifier("securityManager") SecurityManager manager) {
     ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
     //设置securityManager
     bean.setSecurityManager(manager);
     //设置登录页面
     //可以写路由也可以写jsp页面的访问路径
     bean.setLoginUrl("/login");
     //设置登录成功跳转的页面
     bean.setSuccessUrl("/pages/index.jsp");
     //设置未授权跳转的页面
     bean.setUnauthorizedUrl("/pages/unauthorized.jsp");
     //定义过滤器
     LinkedHashMap<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
     filterChainDefinitionMap.put("/index", "authc");
     filterChainDefinitionMap.put("/login", "anon");
     filterChainDefinitionMap.put("/loginUser", "anon");
     filterChainDefinitionMap.put("/admin", "roles[admin]");
     filterChainDefinitionMap.put("/edit", "perms[delete]");
     filterChainDefinitionMap.put("/druid/**", "anon");
     //需要登录访问的资源 , 一般将/**放在最下边
     filterChainDefinitionMap.put("/**", "authc");
     bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
     return bean;
     }
     /**
     * Spring的一个bean , 由Advisor决定对哪些类的方法进行AOP代理 .
     * @return
     */
     @Bean
     public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() {
     DefaultAdvisorAutoProxyCreator creator = new DefaultAdvisorAutoProxyCreator();
     creator.setProxyTargetClass(true);
     return creator;
     }
     /**
     * 配置shiro跟spring的关联
     * @param securityManager
     * @return
     */
     @Bean
     public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(@Qualifier("securityManager") SecurityManager securityManager) {
     AuthorizationAttributeSourceAdvisor advisor = new AuthorizationAttributeSourceAdvisor();
     advisor.setSecurityManager(securityManager);
     return advisor;
     }
     /**
     * lifecycleBeanPostProcessor是负责生命周期的 , 初始化和销毁的类
     * (可选)
     */
     @Bean("lifecycleBeanPostProcessor")
     public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() {
     return new LifecycleBeanPostProcessor();
     }
    }

**注:**这个类每个bean的作用都已在代码中注释说明，这个类就相当于spring整合shiro的spring-shiro.xml中对shiro的配置。

自定义realm:

AutuRealm.java

public class AuthRealm extends AuthorizingRealm{
     @Autowired
     private UserService userService;
     /**
     * 为用户授权
     * @param principals
     * @return
     */
     @Override
     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
     //获取前端输入的用户信息，封装为User对象
     User userweb = (User) principals.getPrimaryPrincipal();
     //获取前端输入的用户名
     String username = userweb.getUsername();
     //根据前端输入的用户名查询数据库中对应的记录
     User user = userService.findByUsername(username);
     //如果数据库中有该用户名对应的记录，就进行授权操作
     if (user != null){
     SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
     //因为addRoles和addStringPermissions方法需要的参数类型是Collection
     //所以先创建两个collection集合
     Collection<String> rolesCollection = new HashSet<String>();
     Collection<String> perStringCollection = new HashSet<String>();
     //获取user的Role的set集合
     Set<Role> roles = user.getRoles();
     //遍历集合
     for (Role role : roles){
     //将每一个role的name装进collection集合
     rolesCollection.add(role.getName());
     //获取每一个Role的permission的set集合
     Set<Permission> permissionSet = role.getPermissions();
     //遍历集合
     for (Permission permission : permissionSet){
     //将每一个permission的name装进collection集合
     perStringCollection.add(permission.getName());
     }
     //为用户授权
     info.addStringPermissions(perStringCollection);
     }
     //为用户授予角色
     info.addRoles(rolesCollection);
     return info;
     }else{
     return null;
     }
     }
     /**
     * 认证登录
     * @param token
     * @return
     * @throws AuthenticationException
     */
     @Override
     protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
     //token携带了用户信息
     UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
     //获取前端输入的用户名
     String userName = usernamePasswordToken.getUsername();
     //根据用户名查询数据库中对应的记录
     User user = userService.findByUsername(userName);
     //当前realm对象的name
     String realmName = getName();
     //盐值
     ByteSource credentialsSalt = ByteSource.Util.bytes(user.getUsername());
     //封装用户信息，构建AuthenticationInfo对象并返回
     AuthenticationInfo authcInfo = new SimpleAuthenticationInfo(user, user.getPassword(),credentialsSalt, realmName);
     return authcInfo;
     }
    }

**注:**这个类也有详细的注释说明。

**这样就完成了springboot对shiro的整合，接下来就可以进行测试了！**

五、测试

![降龙十八掌之 springboot整合shiro(含MD5加密)][springboot_shiro_MD5 9]

图片发自简书App

**测试结果与预期相符，测试通过，springboot整合shiro成功！**

特别说明:

由于设置了MD5加密，所以数据库中存储的用户密码应该是加密后的密文，否则在登录页面输入明文会验证不通过。假如1234的密文为asdfghjkl，数据库中存储的应该是asdfghjkl，在登录时输入1234就能验证通过。

**附上明文转密文的代码:**

public static void main(String[] args) {
     String hashAlgorithName = "MD5";
     String password = "登录时输入的密码";
     int hashIterations = 1024;//加密次数
     ByteSource credentialsSalt = ByteSource.Util.bytes("登录时输入的用户名");
     Object obj = new SimpleHash(hashAlgorithName, password, credentialsSalt, hashIterations);
     System.out.println(obj);
     }

若不使用MD5加密

**1、**添加一个类

public class CredenttiaMatcher extends SimpleCredentialsMatcher{
     @Override
     public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
     UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
     String password = new String(usernamePasswordToken.getPassword());
     String dbPassword = (String) info.getCredentials();
     return this.equals(password,dbPassword);
     }
    }

**2、**将ShiroConfiguration.java中名为"hashedCredentialsMatcher"的bean替换成:

*@Bean("credenttiaMatcher")
     public CredenttiaMatcher credenttiaMatcher() {
     return new CredenttiaMatcher();
     }

将名为"authRealm"的bean替换成:

@Bean("authRealm")
     @DependsOn("lifecycleBeanPostProcessor")//可选
     public AuthRealm authRealm(@Qualifier("credenttiaMatcher") CredenttiaMatcher matcher) {
     AuthRealm authRealm = new AuthRealm();
     authRealm.setCredentialsMatcher(matcher);
     return authRealm;
     }

**3、**AuthRealm.java中的doGetAuthenticationInfo方法里面的内容替换成:

//=========================未加密版==========================
     //token携带了用户登录的信息
     UsernamePasswordToken usernamePasswordToken = (UsernamePasswordToken) token;
     //获取前端输入的用户名
     String username = usernamePasswordToken.getUsername();
     //根据前端输入的用户名查询数据库中的记录
     User user = userService.findByUsername(username);
     //校验密码，验证登录
     return new SimpleAuthenticationInfo(user,user.getPassword(),this.getClass().getName());

**完成以上3步就去掉了MD5加密。**
