Spring AOP获取拦截方法的参数名称跟参数值

开始:

<aop:aspectj-autoproxy expose-proxy="true" />

2.具体代码:

import org.apache.commons.lang3.ArrayUtils;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.reflect.MethodSignature;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
* 请求参数拦截校验
*/
@Aspect
public class AopParamVerify {
private static Logger log = LoggerFactory.getLogger(AopParamVerify.class);

@Around(value = "execution(* com.website.controller..*.*(..))")
public Object invoke(ProceedingJoinPoint joinPoint) {

/**
* 时间戳校验,超过一分钟,拦截
*/
//返回结果封装类
HzlqswReqResult rst = new HzlqswReqResult();
//1.这里获取到所有的参数值的数组
Object[] args = joinPoint.getArgs();
Signature signature = joinPoint.getSignature();
MethodSignature methodSignature = (MethodSignature) signature;
//2.最关键的一步:通过这获取到方法的所有参数名称的字符串数组
String[] parameterNames = methodSignature.getParameterNames();
try {
//3.通过你需要获取的参数名称的下标获取到对应的值
int timeStampIndex = ArrayUtils.indexOf(parameterNames, "timeStamp");
if (timeStampIndex != -1) {
long timeStamp = (Long) args[timeStampIndex];
if (System.currentTimeMillis() - timeStamp > 60000) {
rst.setResultCode(rst.resultCode_hashCode_overdue);
rst.setReturnMsg("时间戳过期");
rst.setReturnObject("时间戳过期");
return rst;
}
}
return joinPoint.proceed();
} catch (Throwable throwable) {
log.error("时间戳校验异常");
throwable.printStackTrace();
rst.setResultCode(rst.resultCode_error);
rst.setReturnMsg("AOP校验异常");
rst.setReturnObject("AOP校验异常");
return rst;
}
}
}
