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"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
             http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
    <persistence-unit name="MyProject">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
        <class>al.das.MyProject.Entities.Entity1</class>
        <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.jdbc.SchemaFactory" value="native(ForeignKeys=true)"/>
            <property name="openjpa.jdbc.MappingDefaults" value="ForeignKeyDeleteAction=restrict, JoinForeignKeyDeleteAction=restrict"/>
            <property name="openjpa.ConnectionURL" value="jdbc:mysql://localhost:3306/myproject"/>
            <property name="openjpa.ConnectionDriverName" value="com.mysql.jdbc.Driver"/>
            <property name="openjpa.ConnectionUserName" value="user"/>
            <property name="openjpa.ConnectionPassword" value="password"/>
            <property name="openjpa.Log" value="DefaultLevel=WARN, Runtime=INFO, Tool=INFO, SQL=TRACE"/>
        </properties>
    </persistence-unit>
</persistence>

有谁知道我做错了什么？
