一、使用元注解：
/**
* 系统日志注解
*
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
String value() default "";
1
}
二、编写系统日志，切面处理类：
package com.jianqiao.tslm.common.aspect;
import com.jianqiao.tslm.common.annotation.SysLog;
import com.jianqiao.tslm.common.utils.KeyUtil;
import com.jianqiao.tslm.entity.SysLogEntity;
import com.jianqiao.tslm.service.SysLogService;
import lombok.Data;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
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 com.google.gson.Gson;
import javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;
import java.util.Date;
import com.jianqiao.tslm.common.utils.HttpContextUtils;
import com.jianqiao.tslm.common.utils.IPUtils;
/**
* 系统日志，切面处理类
*/
@Aspect
@Component
public class SysLogAspect {
@Autowired
private SysLogService sysLogService;
@Pointcut("@annotation(com.jianqiao.tslm.common.annotation.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)
long time = System.currentTimeMillis() - beginTime;
//保存日志
saveSysLog(point, time);
return result;
}
@AfterReturning("logPointCut()")
public void after(JoinPoint point) throws Throwable{
MethodSignature signature = (MethodSignature) point.getSignature();
Method method = signature.getMethod();
SysLog syslog = method.getAnnotation(SysLog.class);
if(syslog != null){
}
String className = point.getTarget().getClass().getName();
String methodName = signature.getName();
System.out.println(className + "." + methodName + "()" + syslog.value());
}
private void saveSysLog(ProceedingJoinPoint joinPoint, long time) {
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
Method method = signature.getMethod();
SysLogEntity sysLog = new SysLogEntity();
SysLog syslog = method.getAnnotation(SysLog.class);
if(syslog != null){
//注解上的描述
sysLog.setOperation(syslog.value());
}
//设置id
sysLog.setId(KeyUtil.genUniquekey());
//请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
sysLog.setMethod(className + "." + methodName + "()");
//请求的参数
Object[] args = joinPoint.getArgs();
try{
String params = new Gson().toJson(args[0]);
sysLog.setParams(params);
}catch (Exception e){
}
//获取request
HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
//设置IP地址
sysLog.setIp(IPUtils.getIpAddr(request));
//用户名
