1.导入依赖

 1　　　　 <!--集成shiro-->
 2         <dependency>
 3             <groupId>org.apache.shiro</groupId>
 4             <artifactId>shiro-spring</artifactId>
 5             <version>1.5.3</version>
 6         </dependency>
 7         <!--shiro整合thymeleaf  shiro前端标签  -->
 8         <dependency>
 9             <groupId>com.github.theborakompanioni</groupId>
10             <artifactId>thymeleaf-extras-shiro</artifactId>
11             <version>2.0.0</version>
12         </dependency>
13

2.配置

创建对象的顺序是自定义的Realm对象然后是DefaultWebSecurityManager ，最后是ShiroFilterFactoryBean

 1 import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
 2 import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
 3 import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
 4 import org.springframework.beans.factory.annotation.Qualifier;
 5 import org.springframework.context.annotation.Bean;
 6 import org.springframework.context.annotation.Configuration;
 7 
 8 import java.util.LinkedHashMap;
 9 import java.util.Map;
10 
11 @Configuration
12 public class ShiroConfig {
13     /**
14      * 3大对象  ShiroFilterFactoryBean DefaultWebSecurityManager 自定义的Realm对象
15      * 创建步骤   3                     2                               1
16      */
17 
18     @Bean
19     public ShiroFilterFactoryBean getShiroFilterFactoryBean(DefaultWebSecurityManager t){
20         ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
21         //Shiro的核心安全接口,这个属性是必须的
22         shiroFilterFactoryBean.setSecurityManager(t);
23 
24         //对没有登录的请求进行拦截   全部返回json信息. 覆盖掉shiro原本的跳转login.jsp的拦截方式
25 //        Map<String, Filter> filterMap = new LinkedHashMap<>();
26 //        filterMap.put("authc", new AjaxPermissionsAuthorizationFilter());
27 //        shiroFilterFactoryBean.setFilters(filterMap);
28 
29         //对没有登录的请求进行拦截   设置跳转的页面
30         shiroFilterFactoryBean.setLoginUrl("/toLogin");
31         //未授权页面
32         shiroFilterFactoryBean.setUnauthorizedUrl("/noauth");
33 
34         /**
35          * 添加shiro的内置过滤器
36          * anon：无需认证就能访问
37          * authc：必须认证才能访问
38          * user: 必须拥有 记住我 功能才能使用
39          * perms: 拥有对某个资源的权限才能访问
40          * role: 拥有某个角色权限
41          */
42         /*定义shiro过滤链  Map结构
43          * Map中key(xml中是指value值)的第一个\'/\'代表的路径是相对于HttpServletRequest.getContextPath()的值来的
44          * 由于是链式的，推荐使用LinkedHashMap
45          */
46         Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
47          /* 过滤链定义，从上向下顺序执行，一般将 / ** 放在最为下边:这是一个坑呢，一不小心代码就不好使了;
48           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 */
49 //        filterChainDefinitionMap.put("/", "anon");
50 //        filterChainDefinitionMap.put("/add", "authc");
51           filterChainDefinitionMap.put("/add", "perms[user:add]");
52         shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
53 
54 
55 
56         return shiroFilterFactoryBean;
57     }
58 
59     //使用Qualifier添加别名
60     //public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm){
61     @Bean
62     public DefaultWebSecurityManager getDefaultWebSecurityManager(){
63         DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
64         defaultWebSecurityManager.setRealm(getUserRealm());
65         return defaultWebSecurityManager;
66     }
67 
68     // @Qualifier("userRealm")  也可以使用Qualifier添加别名
69     @Bean
70     public UserRealm getUserRealm(){
71         //自定义的Realm对象
72         return new UserRealm();
73     }
74 
75     //用于整合 shiro整合thymeleaf   shiro前端标签   前台未设权限的菜单不显示
76     @Bean
77     public ShiroDialect getShiroDialect(){
78         return  new ShiroDialect();
79     }
80 }

自定义的realm

16 
17     //授权
18     @Override
19     protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
20         System.out.println("授权");
21         SimpleAuthorizationInfo simpleAuth = new SimpleAuthorizationInfo();
22         //授予user:add的权限
23         //simpleAuth.addStringPermission("user:add");
24 
25         //获取当前登录对象
26         Subject subject = SecurityUtils.getSubject();
27         //认证方法里  创建SimpleAuthorizationInfo  传入的第一个参数
28         Object principal = subject.getPrincipal();
29         // 认证方法里 传入的是userName  所以打印出来是admin
30         System.out.println(principal);
31 
32         return simpleAuth;
33     }
34     //认证
35     @Override

39         // 获取用户密码
40         String loginName = (String) authcToken.getPrincipal();
41         String password = new String((char[]) authcToken.getCredentials());
42         //后台数据库查询user

50         }
51         if(!user.getString("password").equals(password)){
52             //没找到帐号
53             throw new IncorrectCredentialsException();
54         }
55         //交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，如果觉得人家的不好可以自定义实现
56         SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
57                 user.getString("userName"),
58                 user.getString("password"),
59                 //ByteSource.Util.bytes("salt"), salt=username+salt,采用明文访问时，不需要此句
60                 getName()
61         );
62         //session中不需要保存密码
63         user.remove("password");
64         //将用户信息放入session中
65         SecurityUtils.getSubject().getSession().setAttribute("userInfo", user);
66         return authenticationInfo;
67     }
68 }

后台Controller
