我正在尝试运行 dbtest,但出现以下错误:

"Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [root-context.xml]: Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;"

因此,我还收到以下错误:

"Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'personRepository' defined in class path resource [root-context.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [root-context.xml]: Invocation of init method failed; nested exception is java.lang.AbstractMethodError: org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

所以我们必须看看我的根上下文文件,它看起来如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

<!-- Root Context: defines shared resources visible to all other web components

-->

<bean id="personRepository" class="se.lowdin.civilforsvaret.webapp.repositories.PersonRepositoryJpa" />


<!-- Database -->
<bean id="datasource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="url" value="jdbc:mysql://localhost/civilforsvaret11" />
<property name="username" value="bla" />
<property name="password" value="bla" />
</bean>

<!-- Entity Manager -->
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="datasource" />
<property name="persistenceUnitName" value="civilforsvaret" />
</bean>

<!-- Transaction Manager -->
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>

</beans>

persisence.xml 如下所示:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">

<persistence-unit name="civilforsvaret" transaction-type="RESOURCE_LOCAL">

<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect" />
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
<property name="hibernate.show_sql" value="true"/>
</properties>
</persistence-unit>

</persistence>

这是我的 pom.xml 文件:

我完全是 Spring MVC 的菜鸟,找不到问题。

最佳答案

这听起来像是 ClassLoader 冲突。我敢打赌你的类路径上有 javax.persistence api 1.x,而 Spring 正试图访问 ValidationMode ,仅在 JPA 2.0 中引入。

由于你使用Maven,做mvn dependency:tree,找到 Artifact :

<dependency>
<groupId>javax.persistence</groupId>
<artifactId>persistence-api</artifactId>
<version>1.0</version>
</dependency>

并将其从您的设置中删除。 (见 Excluding Dependencies)

AFAIK 没有针对 JPA 2 的通用发行版,但您可以使用这个特定于 Hibernate 的版本:

<dependency>
<groupId>org.hibernate.javax.persistence</groupId>
<artifactId>hibernate-jpa-2.0-api</artifactId>
<version>1.0.1.Final</version>
</dependency>

好的,因为这不起作用,您似乎仍然在某个地方有一些 JPA-1 版本。在测试方法中,添加以下代码:

System.out.println(EntityManager.class.getProtectionDomain()
.getCodeSource()
.getLocation());

查看指向您的位置并摆脱该工件。


啊,现在我终于看到了问题所在。摆脱这个:

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jpa</artifactId>
<version>2.0.8</version>
</dependency>

替换成

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>3.2.5.RELEASE</version>
</dependency>

另外,您应该将所有测试库(spring-test、easymock 等)设置为

<scope>test</scope>
