Java org.hibernate.HibernateException:无法实例化默认元组化程序

我在配置我的第一个hibernate程序时遇到了一个问题，但是我被困在了过程的最后一步。 以下是stacktrace：

我将student类student.hbm.xml放在edu.aspire.li中，将insert student类放在edu.aspire.daos中，将hibernate.cfg.xml放在默认包中

提前谢谢。

谢谢@cpiercworld，我宣布我的学生为

package edu.aspire.li;

import java.io.Serializable;

public class Student implements Serializable{
    private int sno;
    private String name;
    private String email;
    private long mobile;    

    public Student(){
        System.out.println("This is to construct student");
    }
    public int getSno() {
        return sno;
    }
    public void setSno(int sno) {
        this.sno = sno;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public long getMobile() {
        return mobile;
    }
    public void setMobile(long mobile) {
        this.mobile = mobile;
    }


}

与student.hbm.xml存在名称冲突

<property name ="sname" column="SNAME" type="string" length="100"/>

您是否在JDK 11上运行Spring Boot？ 当我切换到JDK 11时，我遇到了同样的问题。

---

我通过更改Spring引导版本解决了这个问题。

我通过更改Spring Boot版本解决了这个问题。

我在使用JDK11运行Spring Boot 2.0.5时遇到了这个错误。为了修复它，我必须更新javassist库版本（Gradle是我的构建工具）：

有关迁移到JDK11的更多信息，我发现博客文章很有用。或者，.

它会抱怨您的“学生”课程中没有“getSname（）”。在“Student.hbm.xml”文件中，您将列“SNAME”映射到一个名为“SNAME”的JavaBean属性，需要一个“getSname（）/setSname（）”。从示例“main（）”，看起来该属性只是名为“name”，而不是“SNAME”。它抱怨“Student”类中没有“getSname（）”。在“Student.hbm.xml”文件中，您将列“SNAME”映射到一个名为“SNAME”的JavaBean属性，需要一个“getSname（）/setSname（）”。根据前面的注释（@cstroe about Gradle），从示例“main（）”，该属性看起来只是名为“name”，而不是“SNAME”）添加此依赖项应该解决此问题：org.javassist javassist 3.23.1-GA根据前面的评论（@cstroe about Gradle），添加此依赖项应该解决此问题：org.javassist javassist 3.23.1-GA

<property name ="sname" column="SNAME" type="string" length="100"/>

compile('org.javassist:javassist:3.23.1-GA') {force = true}
