Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError：NULL错误 [英] Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError: NULL Error

问题描述

我刚刚将Spring 3.0.5迁移到3.1 GA。我在初始化期间遇到运行时错误：

I have just migrated Spring 3.0.5 to 3.1 GA. I faced runtime error during initialization:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/spring/infrastructure-config.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL

这是我的xml。

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
    <property name="persistenceUnitName" value="MyPersistenceUnit" />
  </bean>

这是什么 java.lang.NoSuchFieldError：NULL 关于？没有3.0.5的问题。

What is this java.lang.NoSuchFieldError: NULL about? Have no issue with 3.0.5.

推荐答案

这意味着版本不匹配 - 最有可能是spring类。所以确保你所有的弹簧罐都是3.1.0。特别是 spring-expression 。 （如果在修复弹簧后它不起作用，还要升级你的JPA提供程序（休眠？）

This means there is a version mismatch--most likely with spring classes. So make sure all your spring jars are 3.1.0. Especially spring-expression. (Also upgrade your JPA provider (hibernate?) if it doesn't work after fixing spring)
