我遇到了 OpenJPA 的另一个问题。即使我在我的 pom.xml 中插入了 openjpa-maven-plugin,我的实体似乎也没有得到增强。
这里是错误代码:
<openjpa-2.4.2-r422266:1777108 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: This configuration disallows runtime optimization, but the following listed types were not enhanced at build time or at class load time with a javaagent: "
al.das.MyProject.Entities.Entity1
al.das.MyProject.Entities.Entity2
al.das.MyProject.Entities.Entity3".
这是我的 pom.xml

我首先认为我可能在插件部分注册了我的实体类的错误路径,但我想出的替代方法没有奏效。
我是否需要在我的工作区文件夹或我的 tomcat 的目录结构中指定我的类文件的路径?
在 tomcat 中,路径是:
wtpwebapps/MyProject/WEB-INF/classes/al/das/MyProject/Entities
在我的工作区中:
MyProject/target/classes/al/das/MyProject/Entities
为了安全起见,我当前的 persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<class>al.das.MyProject.Entities.Entity2</class>
<class>al.das.MyProject.Entities.Entity3</class>
<properties>
<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"/>

<property name="openjpa.ConnectionPassword" value="password"/>
<property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE"/>

</persistence-unit>
</persistence>
有谁知道我做错了什么?
