            <param-name>targetFilterLifecycle</param-name>

    </filter>

        <filter-name>shiroFilter</filter-name>

五、自定义Realm去写登录判断和授权

/**
 * @author Administrator
 * @date 2020/6/11
 */
@Component
public class CustomerRealm extends AuthorizingRealm {

    @Autowired
    private UserService userService;

    {
        HashedCredentialsMatcher hashedCredentialsMatcher=new HashedCredentialsMatcher();
        hashedCredentialsMatcher.setHashAlgorithmName("MD5");
        this.setCredentialsMatcher(hashedCredentialsMatcher);
    }
    /**
     * 授权
     * @param principalCollection
     * @return
     */
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection)
{
        LoginUserVO loginUserVO=(LoginUserVO) principalCollection.getPrimaryPrincipal();
        List<Role> roles = userService.getRoleByUserName(loginUserVO.getUsername());



        SimpleAuthorizationInfo authorizationInfo=new SimpleAuthorizationInfo();
        if(!CollectionUtils.isEmpty(roles))
        {
            for(Role role:roles) {
                authorizationInfo.addRole(role.getRname());
            }
        }
        List<Resource> ress = userService.getResourceByUserName(loginUserVO.getUsername());
        if(!CollectionUtils.isEmpty(ress))
        {
            for(Resource res:ress) {
                authorizationInfo.addStringPermission(res.getCode());
            }
        }
        return authorizationInfo;
    }
    /**
     * 认证
     * @param authenticationToken
     * @return
     * @throws AuthenticationException
     */
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        UsernamePasswordToken token=(UsernamePasswordToken) authenticationToken;
        String username = token.getUsername();
        User user = userService.checkUser(username);
        if(!ObjectUtils.isEmpty(user))
        {
            List<Resource> level0Resouces = userService.getResour0ce0LevelByUserName(username);
            LoginUserVO userVO=new LoginUserVO();
            userVO.setUsername(username);
            userVO.setLevel0(level0Resouces);
            //顶级菜单的第一个的子菜单 也要在这里查询
            AuthenticationInfo authenticationInfo=new SimpleAuthenticationInfo(userVO,user.getPassword(), ByteSource.Util.bytes(user.getSalt()) ,this.getName());
            return authenticationInfo;
        }

        return null;
    }
}

六、获取用户信息并关联shiro

Subject subject = SecurityUtils.getSubject();
       try {
           if (!ObjectUtils.isEmpty(user)) {
               UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(user.getUsername(), user.getPassword());
               subject.login(usernamePasswordToken);
               LoginUserVO loginUserVO= (LoginUserVO) subject.getPrincipal();
               model.addAttribute("loginUserVO",loginUserVO);
               return "index";
           }
       }catch (UnknownAccountException exception)
       {
           model.addAttribute("error","用户不存在");
       }catch (IncorrectCredentialsException exception)
       {
           model.addAttribute("error","用户名或者密码不正确");
       }

七、在JSP页面加入shiro标签

<%@taglib prefix="shiro" uri="http://shiro.apache.org/tags" %

使用shiro标签判断用户权限（根据前缀判断）的模板如下：

<shiro:hasPermission name="moods:manager">
                <li class="layui-nav-item layui-nav-itemed">
                    <a class="" href="javascript:;">商品管理</a>
                    <dl class="layui-nav-child">
                        <shiro:hasPermission name="goods:manager:gtype">
                        <dd><a href="javascript:;">商品分类</a></dd>
                        </shiro:hasPermission>
                        <dd><a href="javascript:;">品牌管理</a></dd>
                        <dd><a href="javascript:;">类型管理</a></dd>
                        <dd><a href="javascript:;">规格管理</a></dd>
                        <dd><a href="javascript:;">商品管理</a></dd>
                    </dl>
                </li>
 </shiro:hasPermission>
