Question

所以我在运行我的Spring WS应用程序时遇到了这个问题，它实现了JPA（或应该实现..）我遇到运行WS的问题，看起来我的Spring上下文找不到文件{{ 1}}我能够相信，因为我的模板中没有生成persistence.xml文件夹（这是带有META-INF的Maven项目模板）我手动创建了archetype org.springframework.ws。

这是HTTP 500：

META-INF

这是我的persistence.xml

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'caChainDao' defined in file [E:\STS\vfabric-tc-server-developer-2.7.2.RELEASE\zz\wtpwebapps\FCAWSv4\WEB-INF\classes\pl\famoc\test\ws\db\dao\caChainDao.class]: 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-ws-servlet.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Cannot parse persistence unit from class path resource [persistence.xml]

这里是我正在寻找的地方

<?xml version="1.0" encoding="UTF-8" ?>
    <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" xmlns="http://java.sun.com/xml/ns/persistence">

    <persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL" />

</persistence>

这里是我的类路径中这个xml的路径：

<property name="persistenceXmlLocation" value="classpath:persistence.xml" />

有人能给我一个提示我缺少什么吗？

Answer 1

检查生成的jar和war文件。 webapp中的内容将存储在war文件中。并且war文件的META-INF目录不在webapp的类路径中。将META-INF目录存储在src / main / resources下，以使其最终位于webapp的WEB-INF / classes目标中，或者存储在WEB-INF / lib中的生成的jar文件中。

Answer 2

你只在类路径之后添加*，如：

<property name="persistenceXmlLocation" value="classpath*:persistence.xml" />

无法从类路径资源解析持久性单元
