【问题描述】:
我正在将一个 ejb 1.0 应用程序迁移到 ejb 3.1 应用程序。当前应用程序在 WebLogic Server 版本中运行:jdk 8 上的 12.1.3.0.0。对于 POC,我选择了一个会话 bean 和一个实体 bean,并通过提供更新的 ejb-jar.xml、orm.xml 和持久性升级到 3.1 .xml(下)。
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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">
<persistence-unit name="myPersistenceUnit" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>java:/myDataSource</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="hibernate.show_sql" value="false"/>
<property name="useColumnNamesInFindColumn" value="true"/>
<property name="useOldAliasMetadataBehavior" value="true"/>
</properties>
</persistence-unit>
</persistence>
然而,我收到以下 xml 解析错误:
weblogic.application.ModuleException: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 6; The processing instruction target matching "[xX][mM][lL]" is not allowed.

Caused by: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 6; The processing instruction target matching "[xX][mM][lL]" is not allowed.
我已经确认persistence.xml 在我的ejb-jar/META-INF 目录中。如果我从我的 ejb.jar 中删除 persistence.xml,则错误消失,会话 bean 查找发生并且实体 bean 持久性失败。所以我假设错误与persistence.xml有关。我以 utf-8 格式保存了 persistence.xml。正如一些帖子所建议的那样,我还确保<? 之前没有空格。有什么指点吗?
