创建名为'entityManagerFactory的bean时出错

我试图运行dbtest但我收到以下错误：

“引起：org.springframework.beans.factory.BeanCreationException：在类路径资源[root-context.xml]中定义名称为'entityManagerFactory'的bean创建错误：init方法的调用失败;嵌套异常是java.lang.AbstractMethodError ：org.springframework.orm.jpa.persistenceunit.SpringPersistenceUnitInfo.getValidationMode（）Ljavax / persistence / ValidationMode;“

因此，我也得到以下错误：

“引起：org.springframework.beans.factory.BeanCreationException：在类路径资源[root-context.xml]中定义名称为'personRepository'的bean创建错误：bean的初始化失败;嵌套异常是org.springframework.beans . factory.BeanCreationException：在类路径资源[root-context.xml]中定义名称为'entityManagerFactory'的bean时出错：init方法的调用失败;嵌套异常是java.lang.AbstractMethodError：org.springframework.orm.jpa.persistenceunit . SpringPersistenceUnitInfo.getValidationMode（）Ljavax /持久/ ValidationMode;

所以我们必须对我的root-context文件进行监视，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"

    <!-- 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 看起来如下：

<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">

                        <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>

我是Spring MVC的完整菜鸟，无法找到问题所在 .

    这听起来像是ClassLoader冲突 . 我敢打赌你在类路径上有javax.persistence api 1.x，而Spring试图访问ValidationMode，这只是在JPA 2.0中引入的 .

    由于您使用Maven，请执行 mvn dependency:tree ，找到工件：

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

    并从您的设置中删除它 . （见Excluding Dependencies）

    AFAIK没有JPA 2的这种通用发行版，但你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>

    好吧，因为那不起作用，你似乎仍然在那里有一些JPA-1版本 . 在测试方法中，添加以下代码：

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

    看看它指向你的地方并摆脱那件神器 .

    啊，现在我终于看到了问题 . 摆脱这个：

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

    并替换它

    <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>

    添加依赖项并没有解决我的问题 .

    这个问题发生在我的最后，因为“附加”字段是“@Entity”类的一部分，并且在数据库中不存在 .

    我从@Entity类中删除了其他字段并且它有效 .
