Question

我正在学习JPA并遇到问题，我在我的persistance文件中使用实体生成的东西（太累了，不能想到这个名字），所以我的实体是最好的。但我加入他们时遇到了问题。

我的问题是我不认为我正确加入实体

调用From（将em注入bean中）

public Department getDepartment(int id){
  Department dep = null;
  dep = em.find(Department.class,id);
 return dep;
}

部门

package com.test1;

import java.util.List;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.OrderBy;

@Entity
public class Department {

 @Id
 private int id;
 private String name;

 @OneToMany(mappedBy="department")
 @OrderBy("name ASC")
 private List<Employee> employees;

 public int getId() {
  return id;
 }

 public void setId(int id) {
  this.id = id;
 }

 public String getName() {
  return name;
 }

 public void setName(String name) {
  this.name = name;
 }

 public List<Employee> getEmployees() {
  return employees;
 }

 public void setEmployees(List<Employee> employees) {
  this.employees = employees;
 }
}

员工

package com.test1;

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

@Entity
public class Employee {
 @Id private int id;

如果有人能给我一个令人惊奇的牌再次感谢乔恩

Answer 1

您的主键（标有@Id）为int，并且您尝试将Long传递给em.find(..) - 改为通过int。

Answer 2

看起来您正在使用Web Service，并且响应的内容与WSDL不匹配。

引起：com.sun.xml.ws.streaming.XMLStreamReaderException：意外的XML标记。预期：{http://test.com/} getDepartmentResponse但找到：{http://schemas.xmlsoap.org/soap/envelope/}信封

您是如何构建响应的？

JPA实体加入问题（我认为）
