java app log4j 配置_Java-未加载log4j2配置

您能帮我找出配置中缺少的步骤吗？

我试图将记录器添加到我非常简单的Web应用程序中：为此,我使用了log4j2(beta9).

我写下了我的log4j2.xml如下

并将其放在WEB-INF文件夹中.

然后,我有一个简单的servlet,它可以执行以下操作

response.setContentType("text/html;charset=UTF-8");

PrintWriter out = response.getWriter();

try {

/* TODO output your page here. You may use following sample code. */

out.println("");

out.println("");

out.println("

");

out.println("

Servlet TestLogger");

out.println("");

out.println("

");

out.println("

Servlet TestLogger at " + request.getContextPath() + "

");

out.println("");

out.println("");

logger.error("error");

logger.info("info");

logger.trace("trace");

logger.debug("debug");

} finally {

out.close();

}

如您所见,这只是尝试查看记录器是否按预期工作,但事实并非如此.

通过在这里阅读web app,我不需要配置应用程序的web.xml,因为它运行的是Servlet 3.0,实际上,如果我尝试添加配置,则会出现以下错误

javax.servlet.UnavailableException: In a Servlet 3.0+ application, you must not define a log4jServletFilter in web.xml. Log4j 2 defines this for you automatically.

但是似乎不加载log4j2配置文件,因为我期望的输出类似于

10:57:55.490 [http-bio-8084-exec-5] ERROR servletstest.TestLogger - error

10:57:55.490 [http-bio-8084-exec-5] INFO servletstest.TestLogger - info

10:57:55.490 [http-bio-8084-exec-5] TRACE servletstest.TestLogger - trace

10:57:55.490 [http-bio-8084-exec-5] DEBUG servletstest.TestLogger - debug

相反,我只得到

10:57:55.490 [http-bio-8084-exec-5] ERROR servletstest.TestLogger - error

似乎无法加载xml文件,并且默认情况下将记录器级别设置为仅错误.

在同一网页中编写

In Tomcat 7 <7.0.43 you will need to change catalina.properties and remove “log4j*.jar” from the jarsToSkip property. You may need to do something similar on other containers if they skip scanning Log4j JAR files.

所以我编辑catalina.properties,因为我正在运行tomcat 7.0.41,并且从jartoskip属性中删除了log4j * .jar.

我究竟做错了什么？

顺便说一下,在web.xml中,我有这个

test

Jersey REST Service

org.glassfish.jersey.servlet.ServletContainer

jersey.config.server.provider.packages

TestLogger

servletstest.TestLogger

Jersey REST Service

/rest/*

TestLogger

/TestLogger

org.apache.logging.log4j.core.web.Log4jServletContextListener

您会注意到版本是2.5,而不是3.0,也许这在某种程度上影响了我？还是球衣配置？

编辑：

我再次尝试将web.xml更改为以下内容,以使Web应用程序版本为3.0,但它不会加载配置..我在做什么错？
