当模块类加载器顺序时，罗马0.9无法正常工作：父级最后

Question

项目描述： WebSphere Application Server 7.Maven项目，它使用Rome0.9。

我正在解决log4j没有记录的问题。问题是log4j.properties已在父项目中设置。 这就是我将模块的类加载器顺序更改为Parent Last的原因。 它修复了log4j的问题，但是应用程序现在抛出以下异常：

<dependency>
    <groupId>rome</groupId>
    <artifactId>rome</artifactId>
    <version>0.9</version>
</dependency> 

我检查了父加载的库，它们包含相同版本的Rome - 0.9。

似乎我在项目中遗漏了一些依赖项。我想知道是否有办法找出哪些库丢失了？

也许你可以建议任何其他解决方案？

Answer 1

我没有搜索丢失的已加载库的解决方案。 但是这个解决方法对我有用： 我在主servlet类的静态块中重新配置了log4j。

static Logger logger = LoggerFactory.getLogger(FeedAggregatorServlet.class);
static {
     Properties p = new Properties();
     ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
     try {
         p.load(classLoader.getResourceAsStream("/FeedAggregatorlog4j.properties"));
     } catch (IOException e) {
         e.printStackTrace();             
     }
    PropertyConfigurator.configure(p);
}
