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

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

这意味着版本不匹配——很可能是 spring 类。所以确保你所有的 spring jar 都是 3.1.0。特别是spring-expression。（如果在修复 spring 后它不起作用，还升级您的 JPA 提供程序（休眠？））

它可能会帮助你。 从 Spring 3.0.3.RELEASE 升级会导致：java.lang.NoSuchFieldError: USER_DECLARED_METHODS

早些时候我有这样的

<dependencies>
<!-- Spring 3 dependencies -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.1.2.RELEASE</version>
</dependency>
...
</dependencies>

然后我加了

<dependencies>
<!-- Spring 3 dependencies -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.1.2.RELEASE</version>
    <exclusions>
        <exclusion>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
        </exclusion>
    </exclusions>
</dependency>
...

</dependencies>
