我得到以下建议:-
@Before(value="@annotation(loggable)", argNames="joinPoint, loggable")
public void before(JoinPoint joinPoint, Loggable loggable) {
Class<? extends Object> clazz = joinPoint.getTarget().getClass();
MethodSignature methodSignature = (MethodSignature) joinPoint
.getSignature();
Method method = methodSignature.getMethod();
String methodName = joinPoint.getSignature().getName();
Object[] args = joinPoint.getArgs();
RequestMapping myAnnotation = method
.getAnnotation(RequestMapping.class);
CodeSignature codeSignature = (CodeSignature) joinPoint
.getSignature();
String[] argNames = codeSignature.getParameterNames();
logger.info(".....");
}
在类 LoggerAspect 中:

}
}
long endTime = System.currentTimeMillis();
logger.debug( " <<<==== Leaving {} in {} ms returnValue: {}", new Object[] {methodName,(startTime-endTime),constructArgumentsString(clazz, returnValue)} );
}
public void afterThrowing(JoinPoint joinPoint, Throwable throwable) {
String methodName = joinPoint.getSignature().getName();
logger.error(" Exception in method:"+methodName, throwable);
}
private String constructArgumentsString(Class<?> clazz, Object... arguments) {
StringBuffer buffer = new StringBuffer();
for (Object object : arguments) {
if (object instanceof byte[]) {
//do nothig
}else {
buffer.append(object);
buffer.append(", ");
}
}
return buffer.toString();
}
private String constructRequestMappingString(RequestMapping myAnnotation) {
StringBuffer buffer = new StringBuffer();
for (String requestURL : myAnnotation.value()) {
buffer.append(requestURL);
}
for (RequestMethod requestMethod : myAnnotation.method()) {
buffer.append(", ");
buffer.append(requestMethod.name().toString());
}
return buffer.toString();
}
private String arguments(String[] argNames, Object[] arguments) {
for (int i = 0; i < arguments.length; i++) {
if ("model".equalsIgnoreCase(argNames[i])) {
String modelInfo = arguments[i].toString();
String[] tokens = modelInfo.split(", ");
for (String token : tokens) {
if (token.startsWith("quoteNumber")) {
return token;
}
}
}
}
return "";
}
}
和这个注解:
package net.prcins.esales.log.annotation;

import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

public @interface Loggable {

我得到错误:java.lang.IllegalArgumentException:错误类型引用不是注释类型:可记录
为什么Loggable没有Annotation？它被标记为@interface
最佳答案
我通过刷新和更新依赖关系解决了这个问题。它在某处没有引用正确的 Loggable 注释。只需确保它指向注释，它正在引用。

我早就知道Ruby中的“常量”(即大写的变量名)不是真正常量。与其他编程语言一样，对对象的引用是唯一存储在变量/常量中的东西。(侧边栏:Ruby确实具有“卡住”引用对象不被修改的功能，据我所知，许多其他语言都没有提供这种功能。)所以这是我的问题:当您将一个值重新分配给常量时，您会收到如下警告:>>FOO='bar'=>"bar">>FOO='baz'(irb):2:warning:alreadyinitializedconstantFOO=>"baz"有没有办法强制Ruby抛出异常而不是打印警告？很难弄清楚为什么有时会发生重新分配。 最佳答案

HashMap中为什么引入红黑树，而不是AVL树呢1.概述开始学习这个知识点之前我们需要知道，在JDK1.8以及之前，针对HashMap有什么不同。JDK1.7的时候，HashMap的底层实现是数组+链表JDK1.8的时候，HashMap的底层实现是数组+链表+红黑树我们要思考一个问题，为什么要从链表转为红黑树呢。首先先让我们了解下链表有什么不好？？？2.链表上述的截图其实就是链表的结构，我们来看下链表的增删改查的时间复杂度增：因为链表不是线性结构，所以每次添加的时候，只需要移动一个节点，所以可以理解为复杂度是N(1)删：算法时间复杂度跟增保持一致查：既然是非线性结构，所以查询某一个节点的时候
SPI接收数据左移一位问题目录SPI接收数据左移一位问题一、问题描述二、问题分析三、探究原理四、经验总结最近在工作在学习调试SPI的过程中遇到一个问题——接收数据整体向左移了一位（1bit）。SPI数据收发是数据交换，因此接收数据时从第二个字节开始才是有效数据，也就是数据整体向右移一个字节（1byte）。请教前辈之后也没有得到解决，通过在网上查阅前人经验终于解决问题，所以写一个避坑经验总结。实际背景：MCU与一款芯片使用spi通信，MCU作为主机，芯片作为从机。这款芯片采用的是它规定的六线SPI，多了两根线：RDY和INT，这样从机就可以主动请求主机给主机发送数据了。一、问题描述根据从机芯片手
