TomEE抛出无效的生命周期转换

标签： java maven tomee multi-module openejb

我正在使用maven多模块方法进行Web应用程序的主要重构。 在一开始，只有一个模块。 我慢慢地打破了功能并创建了主模块依赖的依赖链。

值得一提的其他相关信息： 我们正在使用以下内容：

  • TomEE（Apache TomEE-JAXRS 1.5.1）
  • OpenEJB的
  • Apache Maven
  • JDK 1.7.x

目前我的网络应用程序结构如下：

parent
  pom.xml  
     |
     common
       pom.xml
     |
     persistence
       pom.xml
     | 
     export
       pom.xml
     |
     main
       pom.xml

所以... 公共模块的pom没有其他模块依赖。

持久性模块的pom具有以下依赖关系：

common

导出模块的pom具有以下依赖项：

common
persistence

主模块的pom具有以下依赖关系：

common
persistence
export

父模块的pom指定REACTOR Build Order，如下所示：

common
persistence
export
main

在创建export模块之前，所有内容都可以构建和部署;但是，既然我已经从main中分解了其他内容并将其放入导出模块，那么构建就可以了，但是当我部署生成的WAR文件时，启动时会显示以下堆栈跟踪：

注意堆栈跟踪中提到的TaskDataAccessServices。该类位于persistence模块中。奇怪的是，我刚刚创建的export模块中根本没有使用它。

当天的问题：调试此问题的最佳方法是什么？

我已经考虑逐个退出更改并将类放回主模块---但这可能需要一段时间......

想知道是否有解决这个问题的银弹方法？

干杯。

我打开你的工件，看看它是否真的存在com.myapp.cde.persistence.ejb.TaskDataAccessServices。

这就是这个堆栈跟踪告诉你的：

Caused by: java.lang.NoClassDefFoundError: Could not initialize class com.myapp.cde.persistence.ejb.TaskDataAccessServices at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:274) at org.apache.openejb.assembler.classic.EnterpriseBeanBuilder.load(EnterpriseBeanBuilder.java:425) at org.apache.openejb.assembler.classic.EnterpriseBeanBuilder.loadClass(EnterpriseBeanBuilder.java:405) at org.apache.openejb.assembler.classic.EnterpriseBeanBuilder.build(EnterpriseBeanBuilder.java:81) at org.apache.openejb.assembler.classic.EjbJarBuilder.build(EjbJarBuilder.java:66) ... 19 more

在main pom.xml文件中，我有以下<dependency>：

<dependency>
   <groupId>net.sf.ehcache</groupId>
   <artifactId>ehcache</artifactId>
   <version>2.8.3</version>
</dependency>

在export pom.xml文件中，我有以下<dependency>：

<dependency>
   <groupId>org.slf4j</groupId>
   <artifactId>slf4j-api</artifactId>
   <version>1.7.21</version>
 </dependency>

我很少知道ehcache拥有slf4j的依赖关系。

将ehcache <dependency>更改为以下修复内容：

<dependency>
   <groupId>net.sf.ehcache</groupId>
   <artifactId>ehcache</artifactId>
   <version>2.8.3</version>
   <exclusions>
      <exclusion>
         <groupId>org.slf4j</groupId>
         <artifactId>slf4j-api</artifactId>
      </exclusion>
   </exclusions>
</dependency>

解决这个问题需要我一次退出一件事，直到事情停止。

这里学到的经验：提交小，经常提交。
