1、shiro授权角色、权限
2、Shiro的注解式开发
shiro权限思路
授权
ShiroUserMapper中定义两个方法
// 通过用户ID查询角色
Set<String> getRolesByUserId(Integer userId);
// 通过用户ID查询权限
Set<String> getPersByUserId(Integer userId);在ShiroUserMapper.xml中新增内容
<select id="getRolesByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
select r.roleid from t_shiro_user u,t_shiro_user_role ur,t_shiro_role r
where u.userid = ur.userid and ur.roleid = r.roleid
and u.userid = #{userId}
</select>
<select id="getPersByUserId" resultType="java.lang.String" parameterType="java.lang.Integer">
select p.permission from t_shiro_user u,t_shiro_user_role ur,t_shiro_role_permission rp,t_shiro_permission p
where u.userid = ur.userid and ur.roleid = rp.roleid and rp.perid = p.perid
and u.userid = #{userId}
</select>Service层

}重写自定义MyRealm中的授权方法
/**
* 授权
* @param principals
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
// 当前登录的用户
ShiroUser shiroUser = this.shiroUserService.queryByName(principals.getPrimaryPrincipal().toString());
Set<String> rolrids = this.shiroUserService.getRolesByUserId(shiroUser.getUserid());
Set<String> perdis = this.shiroUserService.getPersByUserId(shiroUser.getUserid());
SimpleAuthorizationInfo info =new SimpleAuthorizationInfo();
info.setRoles(rolrids);
info.setStringPermissions(perdis);
return info;
}注解式开发
常用注解介绍
@RequiresAuthenthentication:表示当前Subject已经通过login进行身份验证;即 Subject.isAuthenticated()返回 true
@RequiresUser:表示当前Subject已经身份验证或者通过记住我登录的
@RequiresGuest:表示当前Subject没有身份验证或者通过记住我登录过，即是游客身份
@RequiresRoles(value = {"admin","user"},logical = Logical.AND):表示当前Subject需要角色admin和user
@RequiresPermissions(value = {"user:delete","user:b"},logical = Logical.OR):表示当前Subject需要权限user:delete或者user:b
ShiroUserController
/**
* 身份认证的注解
* @param req
* @param resp
* @return
*/
@RequiresUser
@RequestMapping("/passUser")
public String passUser(HttpServletRequest req, HttpServletResponse resp){
return "admin/addUser";
}
/**
* 角色认证的注解
* @param req
* @param resp
* @return
* 当前方法必须同时具备1、4的角色ID才能被访问
*/
@RequiresRoles(value = {"1","4"},logical = Logical.OR)
@RequestMapping("/passRole")
public String passPole(HttpServletRequest req, HttpServletResponse resp){
return "admin/listUser";
}
/**
* 权限认证的注解
* @param req
* @param resp
* @return
*/
@RequiresPermissions(value = {"user:update","user:view"},logical = Logical.OR)
@RequestMapping("/passPer")
public String passPer(HttpServletRequest req, HttpServletResponse resp){
return "admin/resetPwd";

shiro注解测试
<li>
<a href="https://zhishitu.com" style="color: #800000;">"${pageContext.request.contextPath}/passUser">身份认证</a>
</li>
<li>
<a href="https://zhishitu.com" style="color: #800000;">"${pageContext.request.contextPath}/passRole">角色认证</a>
</li>
<li>
<a href="https://zhishitu.com" style="color: #800000;">"${pageContext.request.contextPath}/passPer">权限认证</a>

</ul>效果： 没通过验证会跳到 unauthorized.jsp页面通过验证：
