跟着我的步骤：先运行起来再说

一：导包

        <!-- Shiro安全框架 -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-core</artifactId>
            <version>1.4.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-web</artifactId>
            <version>1.4.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.0</version>
        </dependency>

二：ShiroConfig配置


import cn.zyzpp.shiro.CustomRealm;
import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
import org.apache.shiro.spring.LifecycleBeanPostProcessor;
import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.CookieRememberMeManager;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.servlet.SimpleCookie;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;
import java.util.Map;

/** * Create by yster@foxmail.com 2018/5/17/017 20:18 */
@Configuration
public class ShiroConfig {
    /** * 记住我：自动登录-1 */
    @Bean
    public SimpleCookie getSimpleCookie(){
        SimpleCookie simpleCookie = new SimpleCookie();
        simpleCookie.setName("rememberMe");
        simpleCookie.setMaxAge(20000000);
        return simpleCookie;
    }

    /** * 记住我：自动登录-2 */
    @Bean
    public CookieRememberMeManager getCookieRememberMeManager(){
        CookieRememberMeManager cookieRememberMeManager = new CookieRememberMeManager();
        cookieRememberMeManager.setCookie(getSimpleCookie());
        return cookieRememberMeManager;
    }

    /** * 开启MD5加密 * @return */
    @Bean
    public HashedCredentialsMatcher getMatcher(){
        HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
        matcher.setHashAlgorithmName("md5");
        matcher.setHashIterations(1);
        return matcher;
    }

    /** * 自定义Realm密码验证与加密 * @return */
    @Bean
    public CustomRealm getCustomRealm(){
      CustomRealm customRealm = new CustomRealm();
      customRealm.setCredentialsMatcher(getMatcher());
      return customRealm;
    }

    /** * 创建SecurityManager环境 * @return */
    @Bean
    public DefaultWebSecurityManager getSecurityManager(){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(getCustomRealm());
        securityManager.setRememberMeManager(getCookieRememberMeManager());
        return securityManager;
    }

    /** * Shiro在Web项目中的过滤 * @return */
    @Bean
    public ShiroFilterFactoryBean getfilterFactoryBean(){
        ShiroFilterFactoryBean filterFactoryBean = new ShiroFilterFactoryBean();
        filterFactoryBean.setSecurityManager(getSecurityManager());
        /** * 只有在下面配置路径访问权限，Shiro才会执行自动跳转。 * 如果使用Shiro注解权限，就只会报异常， * 就只能采用统一异常处理的方法。 */
        //拦截器.
        Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String,String>();
        // 配置不会被拦截的链接 顺序判断
        filterChainDefinitionMap.put("/static/**", "anon");
        //配置退出 过滤器,其中的具体的退出代码Shiro已经替我们实现了
        filterChainDefinitionMap.put("/user/exit", "logout");
        //<!-- 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;
        //<!-- 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-->
        filterChainDefinitionMap.put("/user/user", "authc");
        // 如果不设置默认会自动寻找Web工程根目录下的"/login.jsp"页面
        filterFactoryBean.setLoginUrl("/user/login");
        // 登录成功后要跳转的链接
        filterFactoryBean.setSuccessUrl("/");
        //未授权界面;
        filterFactoryBean.setUnauthorizedUrl("/user/login");
        filterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        return filterFactoryBean;
    }


    /** * 保证Shiro的声明周期 * @return */
    @Bean
    public LifecycleBeanPostProcessor lifecycleBeanPostProcessor(){
        return new LifecycleBeanPostProcessor();
    }

    /** * 开启Shiro授权生效 * @return */
    @Bean
    public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(){
        return new AuthorizationAttributeSourceAdvisor();
    }

}

三：自定义授权类

import cn.zyzpp.service.user.UserService;
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 org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Lazy;

import java.util.Set;

/** * Create by yster@foxmail.com 2018/5/17/017 20:38 */
public class CustomRealm extends AuthorizingRealm {

    private String ClassName =this.getClass().getName();

    @Autowired
    @Lazy   //必须懒加载，否则Ehcache缓存注解及事务管理注解无效
    private UserService userService;

    {
        super.setName(ClassName);
    }

    /** * 权限处理 * @param principals * @return */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        String username = (String) principals.getPrimaryPrincipal();
        // 从数据库或者缓存中获得角色数据
        Set<String> roles = userService.getRolesByUserName(username);
        Set<String> permissions = userService.getPermissionsByRoles(roles);
        //上面的service层方法需要自己写
        SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo();
        simpleAuthorizationInfo.setStringPermissions(permissions);
        simpleAuthorizationInfo.setRoles(roles);

        return simpleAuthorizationInfo;
    }

    /** * 认证处理 * @param token * @return * @throws AuthenticationException */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        // 1.从主体传过来的认证信息中，获得用户名
        String username = (String) token.getPrincipal();

        // 2.通过用户名到数据库中获取凭证
        String password = userService.getPasswordByUsername(username);
        if(password == null) {
            return null;
        }
        SimpleAuthenticationInfo simpleAuthenticationInfo = new SimpleAuthenticationInfo(username, password, ClassName);
        return simpleAuthenticationInfo;
    }

}

四：使用

1）登录验证：

    @RequestMapping(value = "/login/result", method = RequestMethod.POST)
    public String userLogin(User user) {
        String error = null;
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(user.getMail(), user.getPassword());
        try {
            token.setRememberMe(user.isRememberMe());//记住我
            subject.login(token);
        } catch (UnknownAccountException e) {
            error = "用户名/密码错误";
        } catch (IncorrectCredentialsException e) {
            error = "用户名/密码错误";
        } catch (AuthenticationException e) {
            //其他错误，比如锁定，如果想单独处理请单独catch处理
            error = "其他错误：" + e.getMessage();
        }
        if(error != null) {//出错了，返回登录页面

        } else {//登录成功

        }
    }

2）权限验证：

  • 可以在配置文件中配置Url权限等，参考步骤二。

  • 使用诸如 @RequiresRoles(“user”) 注解在controller层的方法上，进行角色验证，或者使用@RequiresPermissions(“index:hello”)进行权限验证，不过使用注解Shiro就只抛出异常，无法使用shiro设置自动跳转到页面等。针对这个问题，可以用@ControllerAdvice统一异常处理。

    @RequiresRoles("user")
    @RequestMapping(value = "/up")
    public String up(){

    }
