TomEE 抛出无效的生命周期转换
TomEE throws An invalid Lifecycle transition
我正在使用 Maven 多模块方法对 Web 应用程序进行重大重构。
一开始只有 1 个模块。
我一直在慢慢地分解功能并创建主模块所依赖的依赖链。
其他值得一提的相关信息：
我们正在使用以下内容：
- TomEE（Apache TomEE-JAXRS 1.5.1）
- OpenEJB
- 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 没有其他模块依赖项。
持久化模块的 pom 具有以下依赖项：
common
导出模块的 pom 具有以下依赖项：
common
persistence
主模块的pom有以下依赖：
common
persistence
export
父模块的 pom 指定 REACTOR 构建顺序如下：
common
persistence
export
main
在创建 export 模块之前，一切都可以正常构建和部署；然而，现在我已经从 main 中分离出额外的东西并将其放入导出模块中，构建很好，但是当我部署生成的 WAR 文件时，以下堆栈跟踪显示在启动时:

注意堆栈跟踪中提到的 TaskDataAccessServices。此 class 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。
今日问题：调试此问题的最佳方法是什么？
我考虑过一项一项地撤消更改并将 classes 放回主模块中 --- 但这可能需要一段时间...
想知道是否有灵丹妙药来解决这个问题？
干杯。
我会打开你的神器，看看里面是否真的有 com.myapp.cde.persistence.ejb.TaskDataAccessServices。
这就是堆栈跟踪告诉您的内容：

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>
我几乎不知道 ehcache 有它自己对 slf4j 的依赖。
将 ehcache <dependency> 更改为以下为我解决的问题：
<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>
要弄清楚这一点，我需要一次一个地解决问题，直到问题停止为止。
这里的经验教训：少做，多做。
