从JavaEE中的EJB模块进行日志记录，maven配置
我已经尝试了好几个小时来让我的项目工作，但EJB部分仍然失败，出现java.lang.ClassNotFoundException：org.slf4j.LoggerFactory（我想在EJB中输出一些日志）。
该项目的布局如下：
|-- nnWeb-ear | |-- pom.xml | `-- src | `-- main | |-- application | | `-- META-INF | | `-- MANIFEST.MF | `-- java |-- nnWeb-ejb | |-- pom.xml | `-- src | |-- main | | |-- java | | | `-- com | | | `-- test | | | `-- packaging | | | `-- SimpleStateLess.java | | `-- resources | | |-- logback.xml | | `-- META-INF | | `-- MANIFEST.MF | `-- test | `-- java | `-- com | `-- test | `-- packaging |-- nnWeb-web | |-- pom.xml | `-- src | |-- main | | |-- java | | | `-- com | | | `-- test | | | `-- packaging | | | |-- SimpleEJB.java | | | `-- SimpleServlet.java | | |-- resources | | | `-- logback.xml | | `-- webapp | | |-- index.jsp | | `-- WEB-INF | | `-- sun-web.xml | `-- test | `-- java `-- pom.xml

和SimpleStateless.java EJB：
package com.test.packaging;
import javax.ejb.Stateless;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@Stateless
public class SimpleStateLess {
private static Logger logger = LoggerFactory.getLogger(SimpleStateLess.class);
public void constructLog(){
logger.debug("Finally got logging working in ejb module :)");
}
}
一旦打包，ear文件看起来像：
|-- APP-INF | `-- lib | |-- aopalliance-1.0.jar | |-- guice-2.0.jar | |-- logback-classic-0.9.18.jar | |-- logback-core-0.9.18.jar | |-- slf4j-api-1.5.11.jar | |-- slf4j-jdk14-1.5.10.jar | |-- sli4j-core-2.0.jar | `-- sli4j-slf4j-jdk14-2.0.jar |-- META-INF | |-- application.xml | |-- MANIFEST.MF | `-- maven | `-- com.test.packaging | `-- nnWeb-ear | |-- pom.properties | `-- pom.xml |-- ngWeb-web.war `-- nnWeb-ejb.jar
和ejb.jar清单是：
Manifest-Version: 1.0 Archiver-Version: Plexus Archiver Created-By: Apache Maven Built-By: dev Build-Jdk: 1.6.0_21 Class-Path: APP-INF/lib/logback-classic-0.9.18.jar APP-INF/lib/logback -core-0.9.18.jar APP-INF/lib/slf4j-api-1.5.11.jar
请注意，从war包中记录工作（使用WEB-INF / lib目录的Servlet日志记录+ EJB日志记录）并根据我的发现，在部署耳朵时（如果清单正确），登录EJB应该可以工作。
我究竟做错了什么 ？
查看爆炸ear包装和ejb.jar清单，
nnWeb-ejb.jar与APP-INF层次结构相同。
因此，以下Class-Path条目变为无效......
Class-Path: APP-INF/lib/logback-classic-0.9.18.jar APP-INF/lib/logback
-core-0.9.18.jar APP-INF/lib/slf4j-api-1.5.11.jar
他们需要成为
Class-Path: ../APP-INF/lib/logback-classic-0.9.18.jar ../APP-INF/lib/logback
-core-0.9.18.jar ../APP-INF/lib/slf4j-api-1.5.11.jar
