Question

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的内容是什么？对3.0.5没有任何问题。

Answer 1

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spring之后它不起作用，还要升级你的JPA提供程序（休眠？）

Answer 2

它可能对你有所帮助。 Upgrading from Spring 3.0.3.RELEASE results in: java.lang.NoSuchFieldError: USER_DECLARED_METHODS

早些时候我喜欢这个

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

然后我添加了

<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>
