Shiro授权及注解式开发

Shiro授权

　　首先设计shiro权限表:

　　从图中我们也清晰的看出五张表之间的关系

ShiroUserMapper

    Set<String> getRolesByUserId(Integer uid);

    Set<String> getPersByUserId(Integer uid);

ShiroUserMapper.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 = #{uid}

</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 = #{uid}

</select>

Service层

ShiroUserService

    /**

     * 角色验证

     * @param uid

     * @return

     */

    Set<String> getRolesByUserId(Integer uid);

    /**

     * 权限判断

     * @param uid

     * @return

     */

    Set<String> getPersByUserId(Integer uid);

ShiroUserServiceIpml

@Service("shiroUserService")

public class ShiroUserServiceImpl implements ShiroUserService {

    @Autowired

    private ShiroUserMapper shiroUserMapper;

    @Override

    public ShiroUser queryByName(String userName) {

        return shiroUserMapper.queryByName(userName);

    }

    @Override

    public int insert(ShiroUser shiroUser) {

        return shiroUserMapper.insert(shiroUser);

    }

    @Override

    public Set<String> getRolesByUserId(Integer uid) {

        return shiroUserMapper.getRolesByUserId(uid);

    }

    @Override

    public Set<String> getPersByUserId(Integer uid) {

        return shiroUserMapper.getPersByUserId(uid);

    }

}

编写MyRealm中的授权方法去获取数据源

public class MyRealm extends AuthorizingRealm {

    private ShiroUserService shiroUserService;

    public ShiroUserService getShiroUserService() {

        return shiroUserService;

    }

    public void setShiroUserService(ShiroUserService shiroUserService) {

        this.shiroUserService = shiroUserService;

    }

    /**

     * 授权

     * @param principalCollection

     * @return

     */

    @Override

    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {

        ShiroUser shiroUser = this.shiroUserService.queryByName(principalCollection.getPrimaryPrincipal().toString());

        Set<String> roleids = this.shiroUserService.getRolesByUserId(shiroUser.getUserid());

        Set<String> perIds = this.shiroUserService.getPersByUserId(shiroUser.getUserid());

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        info.setRoles(roleids);

        info.setStringPermissions(perIds);

        return info;

    }

}

Shiro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

注意：必须将Shiro注解的开启放置到spring-mvc.xml中（即放在springMVC容器中加载），不然Shiro注解开启无效！

　　所以我们要在Springmvc文件中配置他

Springmvc.xml

<bean class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"

          depends-on="lifecycleBeanPostProcessor">

        <property name="proxyTargetClass" value="true"></property>

    </bean>

    <bean class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">

        <property name="securityManager" ref="securityManager"/>

    </bean>

    <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">

        <property name="exceptionMappings">

            <props>

                <prop key="org.apache.shiro.authz.UnauthorizedException">

                    unauthorized

                </prop>

            </props>

        </property>

        <property name="defaultErrorView" value="unauthorized"/>

    </bean>

再Controller中运用注解

/**

 * @author 黄大娘

 * @company dogsun

 * @oreata 2019-10-14 21:28

 */

@Controller

public class ShiroUserController {

    @Autowired

    private ShiroUserService shiroUserService;/**

     * 讲解身份认证的注释

     * @param req

     * @param resp

     * @return

     */

    @RequiresUser

    @RequestMapping("/passUser")

    public String passUser(HttpServletRequest req, HttpServletResponse resp){

        return "admin/addUser";

    }

    /**

     * 角色认证的注释

     * 此方法只有同时具备1.4两个角色id，才能访问

     * @param req

     * @param resp

     * @return

     */

    @RequiresRoles(value = {"1","4"},logical = Logical.AND)

    @RequestMapping("/passRole")

    public String passRole(HttpServletRequest req, HttpServletResponse resp){

        return "admin/listUser";

    }

    /**

     * 如果角色，身份，权限的认证失败后的处理方式

     * @param req

     * @param resp

     * @return

     */

    @RequestMapping("/unauthorized")

    public String ht(HttpServletRequest req, HttpServletResponse resp){

        System.out.print("处理错误的方式！！！");

        return "login";

    }

    /**

     * 权限认证的注释

     *

     * @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";

    }

}

main.jsp测试

<ul>

    shiro注解

    <li>

        <a href="${pageContext.request.contextPath}/passUser">身份认证</a>

    </li>

    <li>

        <a href="${pageContext.request.contextPath}/passRole">角色认证</a>

    </li>

    <li>

        <a href="${pageContext.request.contextPath}/passPer">权限认证</a>

    </li>

</ul>
