Spring 3.1 entityManagerFactory java.lang.NoSuchFieldError：NULL错误
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
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 ...

<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？ 3.0.5没有问题。
这意味着有一个版本不匹配 – 最有可能与春季class。 所以确保你所有的弹簧jar都是3.1.0。 尤其是spring-expression 。 （如果修复弹簧后不工作，也升级您的JPA提供程序（hibernate？））
它可以帮助你。 从Spring 3.0.3.RELEASE的结果升级：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>
然后我补充说
<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>
