mule - 标题更改为：Mule JPA 模块的问题

Question

我正在尝试将 Hibernate 与 Mule 集成。Mule 是否支持休眠传输？

嗨@大卫，

我曾尝试使用 Mule JPA 模块。但我面临以下问题。请帮助我。

这是我的 applicationContect.xml

这是我的实体类

package com.test.entities;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Table;
import javax.persistence.Transient;

import javax.persistence.*;
import com.test.vo.Contact;
import com.test.vo.ContactVO;

@Entity
@Table(name="contact")

public class ContactEO implements Contact{

    @Transient
    Contact contact;

    @Transient
    public Contact getContact() {
        return contact;
    }

    public void setContact(Contact contact) {
        this.contact = contact;
    }

    public ContactEO(){
        contact = new ContactVO();
    }

    public ContactEO(Contact contact){
        this.contact = contact;
    }

    @Column(name="FIRSTNAME")
    public String getFirstName() {
        return contact.getFirstName();
    }

    public void setFirstName(String firstName) {
        contact.setFirstName(firstName);
    }

    @Column(name="LASTNAME")
    public String getLastName() {
        return contact.getLastName();
    }

    public void setLastName(String lastName) {
        contact.setLastName(lastName);
    }

    @Column(name="EMAIL")
    public String getEmail() {
        return contact.getEmail();
    }
    public void setEmail(String email) {
        contact.setEmail(email);
    }

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name="ID")
    public long getId() {
        return contact.getId();
    }

    public void setId(long id) {
        contact.setId(id);
    }



}
