博客的代码是基于 SSM 环境编写的，而SSM环境的搭建不是本次的重点，所以还不会的搭建环境的可以看下我另外一篇博客：
一、配置文件
在 spring 的配置中，扫描 aop 的包，还有打开注解扫描。
<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"
xmlns:context="http://www.springframework.org/schema/context"
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
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd" >
<!-- 扫描 aop 包 -->
<context:component-scan base-package="com.yyzheng.aop" />
<!-- 打开注解扫描 -->
<aop:aspectj-autoproxy proxy-target-class="true" />
</beans>二、新建一个日志实体类Log
可根据的需求修改实体类参数。
package com.yyzheng.pojo;
import java.io.Serializable;
import java.util.Date;
public class TLog implements Serializable {
private static final long serialVersionUID = 1L;
/**
* 日志id
*/
private Integer id;
/**
* 管理员id
*/
private String adminId;
/**
* 管理员姓名
*/
private String adminName;
/**
* 操作
*/
private String operation;
/**
* 操作方法名
*/
private String method;
/**
* 参数
*/
private String params;
/**
* 消耗时间
*/
private Integer time;
/**
* ip地址
*/
private String ip;
/**
* 操作时间
*/
private Date createTime;
//省略 get and set
}三、编写 service 层
package com.yyzheng.service;
import com.yyzheng.pojo.TLog;
public interface LogService {
public void insertLogInfo(TLog log);
}
四、编写 service 层的实现 serviceimpl
package com.yyzheng.service.impl;
import com.yyzheng.dao.mapping.TLogMapper;
import com.yyzheng.pojo.TLog;
import com.yyzheng.service.LogService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Service
public class LogServiceImpl implements LogService{
@Autowired
private TLogMapper tLogMapper;
@Override
public void insertLogInfo(TLog log) {
//这里调用的是mybatis的逆向工程生成的mapper
tLogMapper.insert(log);
}
}
五、自定义注解类
package com.yyzheng.aop;
import java.lang.annotation.*;
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
String value() default "";
}六、编写切面类
package com.yyzheng.aop;
import java.lang.reflect.Method;
import java.util.Date;
import com.yyzheng.pojo.TAdmin;
import com.yyzheng.pojo.TLog;
import com.yyzheng.service.LogService;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpServletRequest;
/**
* 系统日志，切面处理类
*
*/
@Aspect
@Component
public class SysLogAspect {
@Autowired
private LogService logService;
@Pointcut("@annotation(com.yyzheng.aop.SysLog)")
public void logPointCut() {}
@Around("logPointCut()")
public Object around(ProceedingJoinPoint point) throws Throwable {
long beginTime = System.currentTimeMillis();
//执行方法
Object result = point.proceed();
//执行时长(毫秒)
int time = (int)(System.currentTimeMillis() - beginTime);
//保存日志
saveSysLog(point, time);
return result;
}
private void saveSysLog(ProceedingJoinPoint joinPoint, long time) {
// 获取当前操作的方法
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
TLog log = new TLog();
SysLog syslog = method.getAnnotation(SysLog.class);
if(syslog != null){
//注解上的描述
log.setOperation(syslog.value());
}
//请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
log.setMethod(className + "." + methodName + "()");
// 获取 ip 地址
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
System.out.println("ip地址："+request.getRemoteAddr());
String ip = request.getRemoteAddr();
log.setIp(ip);
//请求的参数
Object[] args = joinPoint.getArgs();
try{
String params = args[0].toString();
log.setParams(params);
}catch (Exception e){
e.printStackTrace();
}
TAdmin admin = (TAdmin)request.getSession().getAttribute("user");
if( admin != null){
log.setAdminId(admin.getAdminId());
log.setAdminName(admin.getAdminName());
log.setCreateTime(new Date());
}
log.setTime((int)time);
// 保存日志
logService.insertLogInfo(log);
}
}
七、spring + aop 需要的 jar 包
<!-- Spring AOP 日志管理需要导入的包 -->
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjrt</artifactId>
<version>1.8.13</version>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.13</version>
</dependency>
<dependency>
