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>

这个 java.lang.NoSuchFieldError: NULL 是关于什么的?3.0.5 没有问题.

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——很可能与 spring 类有关.因此，请确保您所有的弹簧罐都是 3.1.0.特别是spring-expression.(如果修复 spring 后不起作用，还要升级您的 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)
