Question

我已将Hibernate 4.3.4迁移到Maven 3.2.1项目。我用maven-shade-plugin创建了一个jar文件，但是当我启动它时，我有以下异常：

我已经调试过，我发现引发异常的类是org.apache.logging.log4j.core.appender.db.jpa.converter.ContextMapAttributeConverter。

在我的pom中，我依赖log4j 2.0-rc1作为依赖：

  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.0-rc1</version>
  </dependency>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.0-rc1</version>
  </dependency>

在我尝试将所有内容集成到Maven之前，它运行良好。

有什么想法吗？

提前致谢！

正如aaronfc已经提到的，hibernate JIRA上有一张开放票：https://hibernate.atlassian.net/browse/HHH-8804

所以问题是与Log4j2转换器碰撞，更详细的是db appender JPA转换器。

然而，只有“胖”罐才会出现问题...

解决方法：如果您使用 maven-shade-plugin 打包jar - 并且不需要任何log4j2 db appender，则可以排除碰撞的Converter类：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.3</version>
    <executions>
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <shadedArtifactAttached>true</shadedArtifactAttached>
                <shadedClassifierName>jar-with-dependencies</shadedClassifierName> 
                <filters>
                    <filter>
                        <artifact>org.apache.logging.log4j:*</artifact>
                        <excludes>
                            <exclude>org/apache/logging/log4j/core/appender/db/jpa/converter/*</exclude>
                        </excludes>
                    </filter>
                </filters>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 2

我也偶然发现了这一点。 https://hibernate.atlassian.net/browse/HHH-8804

上有一张开放票

我通过降级到Hibernate 4.2.12.Final和JPA2.0来“改变”它。希望它有所帮助！

编辑：对不起，没看到这是一个两个月大的帖子，无论如何希望它对某人有用：P

Answer 3

在扩展到@hartmut的答案时，如果您使用的是Gradle，请添加Gradle Shadow，并在build.gradle中执行以下操作：

shadowJar {
    exclude 'org/apache/logging/log4j/core/appender/db/jpa/converter/*'
}

然后，您可以运行gradle shadowJar来创建jar

Answer 4

我找到了一个有效的解决方法。而不是创建一个“胖”jar，我用我的项目创建了一个Jar，并在一个单独的“lib”文件夹中创建了一个依赖项（当然包括Hibernate）。

我不知道，但它现在有效。

Maven 3.2.1 + Hibernate 4.3.4 - 无法构建实体管理器工厂 - 引起：ParameterizedTypeImpl无法强制转换为java.lang.Class
