需求
系统中的部分业务方法在被调用到时,需要向log表插入日志,业务方法名没有规律。
代码
注解代码
package com.esurer.common.annotation;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
/**
* 系统日志注解
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
String value() default "";
}
切面代码

import com.google.gson.Gson;
import com.esurer.common.annotation.SysLog;
import com.esurer.common.utils.HttpContextUtils;
import com.esurer.common.utils.IPUtils;
import com.esurer.modules.sys.entity.SysLogEntity;
import com.esurer.modules.sys.entity.SysUserEntity;
import com.esurer.modules.sys.service.SysLogService;
import org.apache.shiro.SecurityUtils;
import org.aspectj.lang.ProceedingJoinPoint;

/**

*/
@Aspect
@Component
public class SysLogAspect {
@Autowired
private SysLogService sysLogService;
@Pointcut("@annotation(com.esurer.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;
}
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());
}
//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
String username = ((SysUserEntity) SecurityUtils.getSubject().getPrincipal()).getUsername();
sysLog.setUsername(username);
sysLog.setTime(time);
sysLog.setCreateDate(new Date());
//保存系统日志
sysLogService.save(sysLog);
}
}
使用切面的代码
@SysLog("修改密码")
@RequestMapping("/password")
public R password(String password, String newPassword){
Assert.isBlank(newPassword, "新密码不为能空");
//sha256加密
password = new Sha256Hash(password, getUser().getSalt()).toHex();
//sha256加密
newPassword = new Sha256Hash(newPassword, getUser().getSalt()).toHex();
//更新密码
int count = sysUserService.updatePassword(getUserId(), password, newPassword);
if(count == 0){
return R.error("原密码不正确");
}
return R.ok();
}
