1.AOP的日志拦截类中，抛出异常：
2.代码如下：
package com.jimulian.iwuxi.common.aop;
import com.alibaba.fastjson.JSON;
import com.jimulian.iwuxi.common.annotation.OptLogAno;
import com.jimulian.iwuxi.mapper.OptLogMapper;
import com.jimulian.iwuxi.pojo.OptLog;
import com.jimulian.iwuxi.pojo.User;
import com.jimulian.iwuxi.pojo.module.WeChatUserBean;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
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;
import java.lang.reflect.Method;
import java.util.Date;
/**

@Aspect
@Component
public class OptLogAspect {
@Autowired
private OptLogMapper optLogMapper;
@Pointcut("@annotation(com.jimulian.iwuxi.common.annotation.OptLogAno)")
public void logPointCut(){
}
@AfterReturning("logPointCut()")
public void saveOptLog(JoinPoint joinPoint) {
OptLog optLog =new OptLog();
//从切面织入点处通过反射机制获取织入点处的方法
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
//获取切入点所在的方法
Method method = signature.getMethod();
//获取操作
OptLogAno optLogAno = method.getAnnotation(OptLogAno.class);
if (optLogAno != null) {
String module = optLogAno.module();
String methods = optLogAno.methods();
optLog.setModule(module);
optLog.setMethods(methods);
}
HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes())
.getRequest();
User user = (User) request.getSession().getAttribute("user_access");
if(user!=null){
optLog.setUsername(user.getUsername());
optLog.setCommite(1);
}
WeChatUserBean weChatUserBean = (WeChatUserBean) request.getAttribute("user");
if(weChatUserBean!=null){
optLog.setWechatuser(weChatUserBean.getName());
optLog.setCommite(2);
}
optLog.setDate(new Date());
// 获取访问真实IP
String ipAddress = request.getRemoteAddr();
optLog.setIp(ipAddress);
//获取请求路径
String actionUrl = request.getRequestURI();
optLog.setActionurl(actionUrl);
//接受客户端的数据
Object[] args = joinPoint.getArgs();
//将参数所在的数组转换成json
String params = JSON.toJSONString(args);
optLog.setContent(params);
if(optLog.getWechatuser()!=null ||optLog.getUsername()!=null){
optLogMapper.insert(optLog);
}
}
}
3.经过查询分析其主要原因：对方法的参数使用JSON.toJSONString(args[index])转换时，有异常抛出【如果参数类型是请求和响应的http，使用JSON.toJSONString()转换会抛异常】 解决方法：将不能进行序列化的入参过滤掉，只要留下我们需要记录的入参参数记录到日志中即可 如下图：
4.完成代码如下：

5.加入以上代码之后不报错了 如下图：
