基于spring boot实现空属性赋值和aspect日志

1. 空属性赋值问题

新增工具类
MyBeanUtils

package com.zr0726.news.util;

import org.springframework.beans.BeanWrapper;
import org.springframework.beans.BeanWrapperImpl;

import java.beans.PropertyDescriptor;
import java.util.ArrayList;
import java.util.List;

public class MyBeanUtils {

public static String[] getNullPropertyName(Object source){

BeanWrapper beanWrapper = new BeanWrapperImpl(source);
PropertyDescriptor[] pds = beanWrapper.getPropertyDescriptors();
List<String> nullPropertyName = new ArrayList<>();
for (PropertyDescriptor pd:pds){
String propertyName = pd.getName();
if (beanWrapper.getPropertyValue(propertyName)==null){
nullPropertyName.add(propertyName);
}
}
return nullPropertyName.toArray(new String[nullPropertyName.size()] );
}
}

2.aspect日志

新建aspect包
LogAspect

package com.zr0726.news.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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
@Component
public class LogAspect {

private final Logger logger = LoggerFactory.getLogger(this.getClass());

@Pointcut("execution(* com.zr0726.news.web.*.*(..))")
public void log(){
}

@Before("log()")
public void doBefore(JoinPoint joinPoint){
//获取request
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = attributes.getRequest();
//获得url和ip
String url = request.getRequestURL().toString();
String ip = request.getRemoteAddr();
String classMethod = joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignature().getName();
Object[] args = joinPoint.getArgs();
RequestLog requestLog = new RequestLog(url,ip,classMethod,args);
logger.info("Request : {}",requestLog);
logger.info("--------doBefore--------");
}

@After("log()")
public void doAfter(){
logger.info("--------doAfter--------");
}

@AfterReturning(returning = "result",pointcut = "log()")
public void adAfterReturn(Object result){
logger.info("Result : {}",result);
}

private class RequestLog{
private String url;
private String ip;
private String classMethod;
private Object[] args;

public RequestLog(String url, String ip, String classMethod, Object[] args) {
this.url = url;
this.ip = ip;
this.classMethod = classMethod;
this.args = args;
}

@Override
public String toString() {
return "RequestLog{" +
"url='" + url + '\'' +
", ip='" + ip + '\'' +
", classMethod='" + classMethod + '\'' +
", args=" + Arrays.toString(args) +
'}';
}
}
}
