Question

我有一个正在运行的Web服务，并且可以在正确的URL上阅读我的wsdl。我也有可以使用的服务，模型和使用者，因为当我以调试模式发送请求时，我从数据库中看到了结果。但是，当我的WebMethod返回结果时，我只有一个空响应，并且在glassfish日志中显示一条错误：无法懒惰地初始化角色集合：p3.model.book.Book.borrowing，无法初始化代理-没有会话

我觉得这是我借钱的懒惰，但事实并非如此。

我的模特：

package p3.model.book;

import p3.model.borrowing.Borrowing;

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;

}

在调试模式下，我遇到了麻烦，我不知道如何解决：

debug before response returned

有人有主意吗？

谢谢您的阅读和帮助。

我解决了这样修改模型的麻烦：（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;
    }


}

由于延迟初始化异常，我的webService未针对SOAP返回正确的响应
