问题描述

我正在使用Spring 4.2.2.RELEASE休眠5.0.2.Final开发一个项目，并将其部署在jboss应用服务器7.1.1上。 我必须使用jboss进行部署，这是硬性要求。

我不想使用注释来配置JPA实体（这是一个硬要求），因此我定义了一个orm.xml文件映射。 

<?xml version="1.0" encoding="UTF-8" ?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
                 version="2.0">

    <description>OR Mapping</description>
    <persistence-unit-metadata>
        <xml-mapping-metadata-complete />
    </persistence-unit-metadata>
    <mapped-superclass class="com.lba.backend.rest.models.IdentifiableEntity">
        <attributes>
            <id name="id" />
        </attributes>
    </mapped-superclass>

    <entity class="com.company.rest.models.User">
        <table name="MyUser" />
        <attributes>
            <id name="id" />
            <basic name="username" />
            <basic name="firstName" />
            <basic name="lastName" />
            <basic name="image" />
        </attributes>
    </entity>

定义此映射后，将war文件部署到jboss 7.1.1应用服务器时，服务器启动时出现异常。

我什至查看了休眠源代码，这是引发异常的行AnnotationProxy＃L87-89 

if ( processedValuesFromDescriptor != descriptor.numberOfElements() ) {
            throw new RuntimeException( "Trying to instanciate " + annotationType + " with unknown elements" );
        }

当我从xml文件中删除表格元素时，它可以正常工作，但会抛出相同的异常 

<join-column name="roleId" insertable="false" updatable="false" />

我为控制器和服务编写了Junit4测试用例，但这种情况并没有发生。 我使用spring mvc测试框架使用SpringJUnit4ClassRunner类编写单元测试。

有人知道我为什么要得到这个例外吗？

Syed，正如您所发布的链接所暗示的那样，问题在于混合了JPA 2.0和JPA 2.1库。 您的测试可能正在工作，因为在类路径上首先显示了2.1库。 在您的应用服务器上，首先显示2.0库（可能是hibernate-jpa-2.0-api），您会​​收到错误消息

我有同样的问题，但设置不同。 我的解决方案是从pom.xml中排除对旧的hibernate-jpa-2.0-api lib的传递依赖： 

<dependency>
    <groupId>com.querydsl</groupId>
    <artifactId>querydsl-jpa-codegen</artifactId>
    <version>4.1.2</version>
    <exclusions>
        <exclusion>
            <groupId>org.hibernate.javax.persistence</groupId>
            <artifactId>hibernate-jpa-2.0-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>
