由于延迟初始化异常，我的 webService 没有返回正确的 SOAP 响应答案

【问题标题】：my webService doesn't return a correct response for SOAP because of a lazy initialize exception由于延迟初始化异常，我的 webService 没有返回正确的 SOAP 响应
【发布时间】：2019-01-31 12:07:24
【问题描述】：

我有一个正在运行的网络服务，我可以在正确的 url 上阅读我的 wsdl。我也有我的服务、模型和消费者，因为当我使用调试模式发送请求时，我会从我的数据库中看到结果。但是，当我的 WebMethod 返回结果时，我只有一个空响应和 glassfish 日志中的错误，它说：未能延迟初始化角色集合：p3.model.book.Book.borrowing，无法初始化代理 - 没有会话

我认为这是我借用的延迟加载，但似乎不是那样。

我的模型：

在我的调试模式下，我遇到了这个问题，我不知道如何解决它：

debug before response returned

有人有想法吗？

感谢您阅读并帮助我。

【问题讨论】：

“我认为这是我借用的延迟加载，但似乎不是那样。”异常消息会提示其他情况。
最后，经过多次尝试，我发现我的 f..g 麻烦。这是我的模型，它有注释 OneToMany 和 ManyToOne，当我问一些问题时，下载了一个列表，但我没有 SOAP 的良好格式，所以客户端不理解正确的数据格式。（如果我不清楚，我仍然发布我的解决方案）
避免此类麻烦的最佳方法是在 manytoOne 或 oneToMany 两侧的属性询问上添加 @JsonIgnoreProperties

【解决方案1】：

我解决了像这样修改模型的问题：（删除注释）

package p3.model.book;

import p3.model.work.Work;

import java.io.Serializable;
import java.util.List;

import javax.persistence.*;
import javax.xml.bind.annotation.XmlType;

@Entity
@Table(name = "book")
//@XmlType(name = "Book")
public class Book implements Serializable {

    @Id
    @GeneratedValue(generator = "gen_book", strategy = GenerationType.IDENTITY)
    @SequenceGenerator(name = "gen_book", sequenceName = "seq_book", allocationSize = 1)
    Integer id;

    private String referenceCode;

    private boolean isAvailable;



    public Book(String referenceCode, boolean isAvailable) {
        this.referenceCode = referenceCode;
        this.isAvailable = isAvailable;
    }

    public Book() {
    }

    public Integer getId() {
        return id;
    }

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

    public String getReferenceCode() {
        return referenceCode;
    }

    public void setReferenceCode(String referenceCode) {
        this.referenceCode = referenceCode;
    }

    public boolean isAvailable() {
        return isAvailable;
    }

    public void setAvailable(boolean isAvailable) {
        this.isAvailable = isAvailable;
    }


}
