本文介绍了创建名为“entityManagerFactory"的 bean 时出错的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试运行 dbtest，但出现以下错误:

I am trying to run a dbtest but I get the following error :

"导致:org.springframework.beans.factory.BeanCreationException:使用在类中定义的名称entityManagerFactory"创建 bean 时出错路径资源[root-context.xml]:调用init方法失败；嵌套异常是 java.lang.AbstractMethodError:org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;"

"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，我也收到以下错误:

And because of that I also get the following error:

"导致:org.springframework.beans.factory.BeanCreationException:使用在类路径中定义的名称personRepository"创建 bean 时出错资源 [root-context.xml]:bean 初始化失败；嵌套例外是 org.springframework.beans.factory.BeanCreationException:使用在类中定义的名称entityManagerFactory"创建 bean 时出错路径资源[root-context.xml]:调用init方法失败；嵌套异常是 java.lang.AbstractMethodError:org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;

"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:

So we have to take alook at my root-context file and it look the following : 

<?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="personService" class="se.lowdin.civilforsvaret.webapp.services.PersonServiceImpl" />
     -->

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


    <!-- Database -->
        <bean id="datasource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <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">
                <provider>org.hibernate.ejb.HibernatePersistence</provider>
                <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:

我是 Spring MVC 的完全菜鸟，找不到问题.

I am a complete noob with Spring MVC and cant find the problem.

推荐答案

这听起来像是 ClassLoader 冲突.我敢打赌你在类路径上的某个地方有 javax.persistence api 1.x，而 Spring 正在尝试访问 ValidationMode，仅在 JPA 2.0 中引入.

This sounds like a ClassLoader conflict. I'd bet you have the javax.persistence api 1.x on the classpath somewhere, whereas Spring is trying to access ValidationMode, which was only introduced in JPA 2.0.

既然你用Maven，做mvn dependency:tree，找到神器:

Since you use Maven, do mvn dependency:tree, find the 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.(请参阅排除依赖项)

And remove it from your setup. (See Excluding Dependencies)

AFAIK JPA 2 没有这样的通用发行版，但您可以使用此特定于 Hibernate 的版本:

AFAIK there is no such general distribution for JPA 2, but you can use this Hibernate-specific version:

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

好的，既然这不起作用，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:

OK, since that doesn't work, you still seem to have some JPA-1 version in there somewhere. In a test method, add this code:

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

看看它指向哪里并摆脱那个神器.

See where that points you and get rid of that artifact.

啊，现在我终于看到问题了.摆脱这个:

Ahh, now I finally see the problem. Get rid of this:

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

并将其替换为

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

另外一个注意事项，您应该将所有测试库(spring-test、easymock 等)设置为

On a different note, you should set all test libraries (spring-test, easymock etc.) to

<scope>test</scope>
