Question

我正在使用Maven构建应用程序。我在本地MySql中有一个数据库，当它仍然在Eclipse环境中时，一切似乎都没问题。应用程序和数据库之间的连接功能齐全，无需担心。在Maven，我设定了目标＆＃34; package＆＃34;到目前为止没有出现任何问题，但是当应用程序想要进行SELECT ALL查询时，会遇到此错误：

第28行是：

session = HibernateSessionFact.getSessionFactory().openSession();

任何人都知道为什么我会收到这个例外？

Answer 1

这不是一个确切的答案。但请尝试以下步骤找出问题。

使用类名 ServiceRegistry 在日食中执行Ctrl + Alt + T.如果您获得该类，则将其跟踪到它所在的jar文件。还要记下版本。
使用此命令获取您的依赖关系树 mvn依赖：树
检查依赖关系树结果中是否有步骤1中具有确切版本的jar。

正如您所说，您使用包作为maven目标。您可能在部署目标的类路径中缺少依赖的hibernate-core jar。例如，对于Web应用程序。 jar应该位于服务器中webapps文件夹的 WEB-INF / lib 文件夹中。

Answer 2

我终于设法回答了我的问题。这个问题实际上很明显，正是因为缺乏经验。在POM文件中，我需要向清单添加一个类路径，我这样做：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-jar-plugin</artifactId>
        <version>2.4</version>
        <configuration>
            <archive>
                <manifest>
                    <mainClass>main.java.festival.ArtFestivals</mainClass>
                    <addClasspath>true</addClasspath>
                    <classpathPrefix>lib/</classpathPrefix>
                </manifest>
            </archive>
        </configuration>
  </plugin>

并且有效。
