在IntelliJ上使用OpenJPA进行手动动态增强

如何解决在IntelliJ上使用OpenJPA进行手动动态增强

我正在尝试使用openjpa和MysqL来保留单个类，真的没有什么戏剧性。

Attempt to cast instance "xxx" to PersistenceCapable Failed.  Ensure that it has been enhanced.

所以我环顾四周，发现了这个 https://openjpa.apache.org/builds/2.2.1/apache-openjpa/docs/ref_guide_pc_enhance.html 他们建议使用

java -javaagent:/home/dev/openjpa/lib/openjpa.jar com.xyz.Main

现在，我将其添加到我的intellij运行时配置中的VM-Options中：

-javaagent:/home/xxx/Downloads/apache-openjpa-3.1.2/openjpa-all-3.1.2.jar main.java.entity.Post

但是它似乎无法识别该类：

You have enabled runtime enhancement,but have not specified the set of persistent classes.  OpenJPA must look for Metadata for every loaded class,which might increase class load times significantly.

我认为javaagent的第二个参数是我指定了类，但我错了。

这是我的persistence.xml：

<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.2"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_2.xsd">
<!-- Define persistence unit -->
<persistence-unit name="post">
    <class>main.java.entity.Post</class>
    <properties>
        <property name="openjpa.DynamicEnhancementAgent" value="true"/>
    <property name="javax.persistence.jdbc.url" value="jdbc:MysqL://localhost:3306/DSTEST" />
    <property name="javax.persistence.jdbc.driver" value="com.MysqL.jdbc.Driver" />
    <property name="javax.persistence.jdbc.user" value="xxx" />
    <property name="javax.persistence.jdbc.password" value="xxx" />
    </properties>
</persistence-unit>

这是我的实体：

package main.java.entity;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity (name="post")
public class Post {
@Id
private Integer postid;

private String user;

private Integer datum;

private String inhalt;

public Integer getPostid() {
    return postid;
}

public void setPostid(Integer postid) {
    this.postid = postid;
}

public String getUser() {
    return user;
}

public void setUser(String user) {
    this.user = user;
}

public Integer getDatum() {
    return datum;
}

public void setDatum(Integer datum) {
    this.datum = datum;
}

public String getInhalt() {
    return inhalt;
}

public void setInhalt(String inhalt) {
    this.inhalt = inhalt;
}
}

我正在Ubuntu上使用Intellij。
