使用spring aop + 注解完成对业务操作的日志记录

话不多说直接上代码，不喜勿喷
@After("@annotation(com.你的路径.service.LogAntn)")
public void afterAdvice(JoinPoint joinPoint) throws ClassNotFoundException, InstantiationException, IllegalAccessException, NoSuchFieldException, SecurityException{

Map<String, String> paramsMap = null;
for (Object object : args) {
if(object instanceof User){

}else if(object instanceof Map){
paramsMap = (Map<String, String>)object;
}
}
LogAntn logAntn = getAntn(joinPoint);
String signature = joinPoint.getSignature().toString(); // 获取目标方法签名
String methodName = signature.substring(signature.lastIndexOf(".") + 1,signature.indexOf("("));
String clazzName = joinPoint.getTarget().getClass().getName();
Class<?> clazz = Class.forName(clazzName);
Method[] methods = clazz.getDeclaredMethods();
for (Method method : methods) {
if (method.isAnnotationPresent(LogAntn.class)&& method.getName().equals(methodName)) {
opObj opObjType = logAntn.opObjType();
String objVal = opObjType.getValue();//操作对象
opType type = logAntn.type();
String opVal = type.getValue();//操作类型
//添加入库操作
}
}
logger.info("aop log ... this is after Advice......");
}
