Shiro授权
1.shiro授权角色、权限
授权
Mapper接口
Set<String> getRolesByUserId(@Param("userid") Integer userid); Set<String> getPersByUserId(@Param("userid") Integer userid);
Mapper.xml
<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
public Set<String> getRolesByUserId(Integer userId); public Set<String> getPersByUserId(Integer userId);
ShiroUserServiceImpl
@Service("shiroUserService") public class ShiroUserServiceImpl implements ShiroUserService { @Autowired private ShiroUserMapper shiroUserMapper; @Override public Set<String> getRolesByUserId(Integer userId) { return shiroUserMapper.getRolesByUserId(userId); } @Override public Set<String> getPersByUserId(Integer userId) { return shiroUserMapper.getPersByUserId(userId); } }
重写自定义realm中的授权方法
/** * 授权 * * @param principalCollection * @return */ @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { String uname = principalCollection.getPrimaryPrincipal().toString(); ShiroUser shiroUser = this.shiroUserService.queryByName(uname); Set<String> perids = this.shiroUserService.getPersByUserId(shiroUser.getUserid()); Set<String> roleIds =this.shiroUserService.getRolesByUserId(shiroUser.getUserid()); SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); info.setRoles(roleIds); info.setStringPermissions(perids); 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
注解的使用
@RequiresUser
@ResponseBody
@RequestMapping("/passUser")
public String passUser() {
return "身份认证成功";
}
@RequiresRoles(value={"1","4"},logical = Logical.OR)
@ResponseBody
@RequestMapping("/passRole")
public String passRole() {
return "角色认证成功";
}
@RequiresPermissions(value={"user:update","user:create"},logical = Logical.AND)
@ResponseBody
@RequestMapping("/passPer")
public String passPer() {
return "权限认证成功";
}
