AOP 的 JoinPoint 参数方法详解
重要方法
/*获取参数的值数组*/
Object[] args = point.getArgs(); // [1] 参数的值
/*获取目标对象(被加强的对象)*/
Object target = point.getTarget();
/*获取signature 该注解作用在方法上,强转为 MethodSignature*/
MethodSignature signature = (MethodSignature) point.getSignature();
/*方法名*/
String signatureName = signature.getName(); // findById
/*参数名称数组(与args参数值意义对应)*/
String[] parameterNames = signature.getParameterNames(); // [i] 参数名称
/*获取执行的方法对应Method对象*/
Method method = signature.getMethod();
// public void com.jueee.test.service.UserService.findById(int)
/*获取返回值类型*/
Class returnType = signature.getReturnType(); // void
/*获取方法上的注解*/
OperationLog operationLog = method.getDeclaredAnnotation(OperationLog.class);
request / response
// 获取request/response(ThreadLocal模式)
RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) requestAttributes;
HttpServletRequest request = servletRequestAttributes.getRequest();
HttpServletResponse response = servletRequestAttributes.getResponse();
HttpSession session = request.getSession();
