springAOP(Aspect)权限访问页面

1、XML进行配置切面

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <bean id="jurisdictionAdvice" class="com.wbg.sums.web.aspect.jurisdictionAdvice"/>
        <aop:config>
            <!--定义切面-->
            <aop:aspect id="authAspect" ref="jurisdictionAdvice">
                <!-- 定义切入点-->
               <aop:pointcut id="jurisdictionPointCut" expression="
                 execution(* com.wbg.sums.web.*.deleteByPrimaryKey(..)) or
                 execution(* com.wbg.sums.web.*.updateByPrimaryKey(..))
                 "/>
                <!--方法环绕-->
               <aop:around method="readOnly" pointcut-ref="jurisdictionPointCut"/>
           </aop:aspect>
       </aop:config>
</beans>

2、定义切面和切点

package com.wbg.sums.web.aspect;

import com.wbg.sums.dto.Result;
import com.wbg.sums.entity.Jurisdiction;
import com.wbg.sums.service.JurisdictionService;
import com.wbg.sums.service.MemberInformationService;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.stereotype.Component;
import javax.servlet.http.HttpSession;

@Component
@Aspect
@EnableAspectJAutoProxy
public class jurisdictionAdvice {

    @Autowired
    HttpSession httpSession;
    //用户
    @Autowired
    private MemberInformationService memberInformationService;
    //权限
    @Autowired
    private JurisdictionService jurisdictionService;

    public Result readOnly(ProceedingJoinPoint pj){
        //方法
        String method = pj.getSignature().getName();
        System.out.println(method);
        //获取用户
       String user = (String) httpSession.getAttribute("user");
       //模拟updateByPrimaryKey
       if(method.equals("updateByPrimaryKey")){
           user="100010003";
       }else {
           user="100010004";
       }
        //查询根据用户查询权限
       int jid = memberInformationService.selectJid(user);
        //获取权限
        System.out.println(jid);
        Jurisdiction jurisdiction = jurisdictionService.selectByPrimaryKey(jid);
        System.out.println(jurisdiction);
        //如果是最高管理
        if(jid == 1){
            try {
                return (Result) pj.proceed();
            } catch (Throwable throwable) {
                throwable.printStackTrace();
            }
        }//如果是中级管理 并方法是修改
        else if( jid == 2 && method.equals("updateByPrimaryKey")){
            try {
                return (Result) pj.proceed();
            } catch (Throwable throwable) {
                throwable.printStackTrace();
            }
        }
            return new Result().error("权限不足");

    }
}

3、controller层

Result代码：

package com.wbg.sums.dto;

public class Result {

//    1203错误编码
//       1224正确编码，有返回数据
//       1028正确编码，无返回数据
//       1222 正确编码 无错误  用于判断删除成功或者失败

    /**
     * 当修改添加删除 成功的时候，统一使用successMessage方法   编码为1028  否则就是没有成功
     *
     */


    //状态码
    int code;
    //数据
    Object data;
    //消息提示
    String message;

    public Result() {
    }

    public Result(String message) {
        this.code=1222;
        this.message = message;
    }

    //数量
    int count;

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }

    public Result(int code, String message, Object data, int count) {
        this.code = code;
        this.data = data;
        this.message = message;
        this.count = count;
    }
    public Result(int code, String message) {
        this.code = code;
        this.message = message;
    }
    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public Object getData() {
        return data;
    }

    public void setData(Object data) {
        this.data = data;
    }

    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }

    /**
     * successMessage
     * 正常返回，携带消息
     * code:1028
     *
     * @param message 消息
     *                data:null
     *                count:0
     * @return
     */
    public static Result successMessage(String message) {
        return new Result(1028, message);
    }


    /**
     * success
     * 成功方法 带数据返回
     * code:1224
     *
     * @param data    数据
     * @param count     总数
     * @return
     */
    public static Result success(Object data, int count) {
        return new Result(1224, "success", data, count);
    }

    /**
     * success
     * 成功方法 带数据返回
     * code:1224
     * message: success
     *
     * @param data 数据
     *             count :0
     * @return
     */
    public static Result success(Object data) {
        return new Result(1224, "success", data, 0);
    }

    /**
     * error
     * code:203
     * data:null
     * count:0
     *
     * @param message 错误信息
     * @return
     */
    public static Result error(String message) {
        return new Result(1203, message);
    }

}
