我有StudentGroup.class:

 package com.grades.model;

    import javax.persistence.Column;
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.Id;
    import javax.persistence.Table;
    import javax.persistence.UniqueConstraint;

    @Entity
    @Table(name = "StudentGroup", uniqueConstraints = { @UniqueConstraint(columnNames = "group_number") })
    public class StudentGroup {

        @Id
        @GeneratedValue
        @Column(name = "id")
        private int id;
        @Column(name = "group_number")
        private int groupNumber;

        public StudentGroup() {

        }

        public StudentGroup(int groupNumber) {

            this.groupNumber = groupNumber;
        }

        public int getId() {
            return id;
        }

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

        public int getGroupNumber() {
            return groupNumber;
        }

        public void setGroupNumber(int groupNumber) {
            this.groupNumber = groupNumber;
        }

        @Override
        public String toString() {
            return "StudentGroup [id=" + id + ", groupNumber=" + groupNumber + "]";
        }
    }


在我的数据库中,我有一个名为“ student_group”的表,当我尝试使用休眠插入一行时,在Tomcat中收到以下异常:SEVERE:Servlet [mvc-dispatcher]的Servlet.service(),路径为[/应用程序]引发异常[请求处理失败;嵌套的异常是org.hibernate.exception.SQLGrammarException:无法插入:[com.grades.model.StudentGroup]],其根本原因是
    com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException:表'db.studentgroup'不存在

有人可以帮我解决这个问题吗?

最佳答案

此“ @Table(name =“ StudentGroup”“)表示您的数据库表应命名为“ StudentGroup”,并相应地更改注释或表名。
