所以我在运行实现 JPA 的 Spring WS 应用程序时遇到了这个问题（或者应该实现..）我在运行 WS 时遇到了问题，看起来我的 Spring 上下文找不到文件persistence.xml，因为我做到了我手动创建的模板中没有生成META-INF文件夹（这是 Maven 项目模板archetype org.springframework.ws） 。 这是 HTTP 500：META-INF

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]

这是我的persistence.xml

<?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>

这就是我要找的地方

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

这是我的类路径中此 xml 的路径：

src/main/webapp/META-INF/persistence.xml

谁能给我一个提示我错过了什么？

检查您生成的 jar 和 war 文件。webapp 内部的内容将存储在 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 目录存放在 src/main/resources 下，使其最终存放在 webapp 的 WEB-INF/classes 目录中，或者存放在 WEB-INF/lib 中生成的 jar 文件中。

您只在类路径之后添加 *，例如：

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