4.SpringBoot入门教程之集成AOP

AOP为Aspect Oriented Programming的缩写，意为：面向切面编程，是Spring框架中的一个重要内容，基于AOP不会侵入或破坏程序中原有的业务逻辑，对业务逻辑代码进行了很好的隔离。AOP的应用场景通常是通过横向切入程序进行一些日志的记录，数据库连接的打开或则关闭，监控系统当前内存的状况，对请求的特殊字符进行过滤等，下面就是SpringBoot集成AOP的一个小Demo。

创建一个maven项目

这里我就不多说了，按照步骤来吧！！！
步骤1：

步骤2：

步骤3：

步骤4：

步骤5：

自此，一个maven项目创建完毕

配置pom.xml

程序目录结构

创建MyApplication启动类

说明:
1.不要直接在java目录下直接创建类，要新建一个package
2.类名可以随便取，但是要遵循命名规范

package com;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Created by Administrator on 2018/5/20 0020.
 */
@SpringBootApplication
public class MyApplication {
    public static void main(String[] args){
        SpringApplication.run(MyApplication.class, args);
    }
}

说明：@SpringBootApplication相当于添加@Configuration,@EnableAutoConfiguration,@ComponentScan三个注解

创建控制器MasterController类

package com.controller;

import com.service.MasterService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.Map;

/**
 * Created by Administrator on 2018/5/22 0022.
 */
@RestController
@RequestMapping("master")
public class MasterController {
    @Autowired
    private MasterService masterService;
    @RequestMapping("/master")
    private String getList(){
        List<Map> list = masterService.getList();
        return list.toString();
    }
}

创建控制器MasterController类

package com.controller;


import com.service.SlaveService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.Map;

/**
 * Created by Administrator on 2018/5/22 0022.
 */
@RestController
@RequestMapping("slave")
public class SlaveController {
    @Autowired
    private SlaveService slaveService;

    @RequestMapping("/slave")
    private String getList(){
        List<Map> list = slaveService.getList();
        return list.toString();
    }
}

创建MasterService业务类

package com.service;

import com.mapper.master.MasterMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Map;

/**
 * Created by Administrator on 2018/5/22 0022.
 */
@Service
public class MasterService{
    @Autowired
    private MasterMapper masterMapper;

    public List<Map> getList(){
        List<Map> list = masterMapper.getList();
        return list;
    }
}

创建SlaveService业务类

package com.service;

import com.mapper.slave.SlaveMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;

import java.util.List;
import java.util.Map;

/**
 * Created by Administrator on 2018/5/22 0022.
 */
@Service
public class SlaveService {
    @Autowired
    private SlaveMapper slaveMapper;

    public List<Map> getList(){
        List<Map> list = slaveMapper.getList();
        return list;
    }
}

创建MasterMapper类

package com.mapper.master;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;
import java.util.Map;

/**
 * Created by Administrator on 2018/5/22 0022.
 */
@Mapper
public interface  MasterMapper {

    @Select("select * from t_token")
    List<Map> getList();
}

创建SlaveMapper类

package com.mapper.slave;

import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;

import java.util.List;
import java.util.Map;

/**
 * Creay Administrator on 2018/5/22 0022.
 */
@Mapper
public interface SlaveMapper {

    List<Map> getList();
}

创建MyAspect类

package com;

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;

/**
 *  @Aspect注解将一个java类定义为切面类
 *  @Pointcut定义一个切入点，可以是一个规则表达式，比如下例中某个package下的所有函数，也可以是一个注解等
 *  @Before在切入点开始处切入内容
 *  @After在切入点结尾处切入内容
 *  @AfterReturning在切入点return内容之后切入内容（可以用来对处理返回值做一些加工处理）
 *  @Around在切入点前后切入内容，并自己控制何时执行切入点自身的内容
 *  @AfterThrowing用来处理当切入内容部分抛出异常之后的处理逻辑
 * Created by Administrator on 2018/5/23 0023.
 */

@Aspect
@Component
public class MyAspect{

    private Logger logger = Logger.getLogger(MyAspect.class);

    //申明一个切点 里面是 execution表达式
    @Pointcut("execution(public * com.controller..*(..))")
    public void webLog(){

    }
    //在切入点开始处切入内容
    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 接收到请求，记录请求内容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        // 记录下请求内容
        String url =  request.getRequestURL().toString();
        String method = request.getMethod();
        String ip = request.getRemoteAddr();
        String class_method = joinPoint.getSignature().getDeclaringTypeName();
        String name = joinPoint.getSignature().getName();
        String args = Arrays.toString(joinPoint.getArgs());
        logger.info("URL : " +url);
        logger.info("HTTP_METHOD : " + method);
        logger.info("IP : " + ip);
        logger.info("CLASS_METHOD : " + class_method + "." + name);
        logger.info("ARGS : " + args);
        System.out.println("URL : " +url);
        System.out.println("HTTP_METHOD : " + method);
        System.out.println("IP : " + ip);
        System.out.println("CLASS_METHOD : " + class_method + "." + name);
        System.out.println("ARGS : " + args);

    }
    //在切入点return内容之后切入内容,可以用来对处理返回值做一些加工处理
    @AfterReturning(returning = "ret", pointcut = "webLog()")
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容
        logger.info("RESPONSE : " + ret);
    }
}

创建MasterMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.mapper.master.MasterMapper" >


</mapper>

创建SlaveMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.mapper.slave.SlaveMapper" >
    <select id="getList" resultType="java.util.Map">
        select * from db
    </select>
</mapper>

修改Tomcat容器的启动端口

在resources目录下创建application.properties文件，并添加端口配置和数据源连接配置

spring.datasource.master.url=jdbc:mysql://39.108.86.136:3306/wechart
spring.datasource.master.username=root
spring.datasource.master.password=root
spring.datasource.master.driverClassName=com.mysql.jdbc.Driver


spring.datasource.slave.url=jdbc:mysql://39.108.86.136:3306/mysql
spring.datasource.slave.username=root
spring.datasource.slave.password=root
spring.datasource.slave.driverClassName=com.mysql.jdbc.Driver

server.port=9999

启动测试

1.启动项目：在MyApplication.java类中运行mian方法

2.检查日志

说明：如果需要打印出sql语句的执行情况，则需要在log4j.properties文件中将log4j.appender.stdout.threshold=INFO修改为log4j.appender.stdout.threshold=DEBUG即可

3.通过浏览器访问接口
http://localhost:9999/slave/slave

4.控制台打印信息

如果AOP的配置没有起到效果可能是因为Controller中的方法写成了private私有方法，可以尝试将private修饰修改public。以上是一个创建一个SpringBoot集成AOP的Demo，因作者水平有限，难免会有疏忽和错误，读者可以参考一些SpringBoot官方文档，如下：
