Error creating entityManagerFactory due to error tying to scan <jar-file>
提问by Chad
I am following http://spring.io/guides/tutorials/data/3; I am not sure what I did wrong, but I keep on getting exceptions that I don't understand. I tried searching for questions with the same exceptions to no avail.
我正在关注http://spring.io/guides/tutorials/data/3；我不确定我做错了什么，但我不断收到我不理解的异常。我尝试搜索具有相同例外情况的问题，但无济于事。

The error:
错误：
invalid constant type: 18
Indicates that you have built the Jars with Java 8, but are attempting to run the application in a lower version.
表示您已使用 Java 8 构建了 Jars，但正在尝试以较低版本运行该应用程序。
From what I have seen elsewhere, you probably need to switch to a newer version of javassist (which is raising the error), as the version you are using is not compatible with Java 8.
从我在其他地方看到的情况来看，您可能需要切换到较新版本的 javassist（这会引发错误），因为您使用的版本与 Java 8 不兼容。

You do not need to provide beans for EntityManagerFactory and EntityManager. Just provide a bean LocalContainerEntityManagerFactoryBean
您不需要为 EntityManagerFactory 和 EntityManager 提供 bean。只需提供一个 bean LocalContainerEntityManagerFactoryBean

I had the same problem while migrating one of my projects to Java 8. Fixed it by updating the hibernate-entitymanager artifact version from 4.2.0.Final to 4.3.8.Final.
我在将我的一个项目迁移到 Java 8 时遇到了同样的问题。通过将 hibernate-entitymanager 工件版本从 4.2.0.Final 更新到 4.3.8.Final 来修复它。

First, get the version of javassistthat works with Java 8:
首先，获取javassist适用于 Java 8的版本：
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.18.2-GA</version>
</dependency>
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.18.2-GA</version>
</dependency>
If you use maven, exclude all others javassistdependencies:
如果您使用 maven，请排除所有其他javassist依赖项：
`<exclusions>
<exclusion>
<artifactId>javassist</artifactId>
<groupId>org.javassist</groupId>
</exclusion>
</exclusions>`
回答by gmode
I had similar issue. My problem was that I had another dependency (in my case jboss weld) that used different version of javassist. Excluding did not help.
我有类似的问题。我的问题是我有另一个依赖项（在我的例子中是 jboss 焊缝），它使用了不同版本的 javassist。排除没有帮助。
<dependency>
<groupId>org.jboss.weld</groupId>
<artifactId>weld-se</artifactId>
<version>1.0.1-Final</version>
<scope>test</scope>
<exclusions>
<exclusion>
<artifactId>javassist</artifactId>
<groupId>org.javassist</groupId>
</exclusion>
</exclusions>
</dependency>
So, above exclusion does not work. I had to find a workaround for jboss weld.
因此，上述排除不起作用。我不得不为 jboss 焊接找到一个解决方法。
回答by Akvel
If you use 3.6.10-Final you need exclude javassist (without org.prefix)
如果您使用 3.6.10-Final，则需要排除 javassist（不带org.前缀）
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>3.6.10.Final</version>
<scope>compile</scope>
<exclusions>
<exclusion>
<artifactId>javassist</artifactId>
<groupId>javassist</groupId>
</exclusion>
</exclusions>
</dependency>
<!-- javassist with fixed https://issues.jboss.org/browse/JASSIST-174 -->
<dependency>
<groupId>org.javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.18.2-GA</version>
