我刚开始使用log4j2.但我发现log4j2包含stacktrace中的库名.我怎么能禁用它？
这是一个例子:
java.lang.NullPointerException
at com.sev.controllers.UserController.login(UserController.java:35) ~[UserController.class:?]
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_31]

我在[]括号中谈论这个名字.
这是我的log4j配置
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n"/>

<Loggers>

<Logger name="org.springframework" level="INFO"/>
<Root level="debug">

</Root>
</Loggers>
</Configuration>
这是我的版本:

</dependency> …我正在Facebook上开发一个应用程序,我需要有可能将我的应用程序集成到其他网站上(通过Facebook JavaScript API连接到Facebook).
在Facebook上,我可以使用Facebook Credits在应用程序上购买一些东西,但在其他网站上,当我调用Facebook购买对话框时,我收到此错误:
API Error Code: 1151
API Error Description: Sorry, but this app may not be eligible to accept Facebook Credits.
If this app has accepted credits before, please try again.
Error Message: Invalid Application
或者是否有我们只能在Facebook上使用的Facebook购买对话框？
我有jstl代码,它由maven很好地构建......但Eclipse有编译错误"Unknown tag(c:foreach)."
代码在这里:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<body>
<ul>
<c:forEach items="${listOfMyFriends}" var="friend">
<c:out value="${friend}"></c:out>
</c:forEach>
</ul>
</body>
</html>
有人可以帮助我避免这个问题吗？

控制器在MyController.java中
@Controller
public class MyController {

LinkedList<String> listOfMyFriends = new LinkedList<String>();
listOfMyFriends.add("friend1");
