Question

作为输出我收到错误：

org.hibernate.InvalidMappingException：无法从资源User.hbm.xml解析映射文档。

我尝试使用链接解决它：

Could not parse mapping document from resource Books.hbm.xml

Hibernate and maven: Could not parse mapping document from resource

我正在尝试使用pojo类

在数据库中输入值

User.hbm.xml

               <hibernate-mapping>
    <class name="com.program.User" table="user">
        <id name="ID" type="int" column="id">
            <generator class="increment" />
        </id>
        <property name="NAME" type="java.lang.String" column="name">
            <column name="name" />
        </property>
        <property name="AGE" type="int" column="age">
            <column name="age" />
        </property>
    </class>
</hibernate-mapping>

Program.java

            package com.program;

            import org.hibernate.Session;
            import org.hibernate.SessionFactory;
            import org.hibernate.cfg.Configuration;

            public class Program {

                public static void main(String[] args) {
                    try{
                        System.out.println("hello world");
                        SessionFactory factory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();;
                        Session session = factory.openSession();
                        session.beginTransaction();
                        User user = new User();
                        user.setID(1);
                        user.setNAME("Toral");
                        user.setAGE(21);
                        session.save(user);
                        session.getTransaction().commit();
                        session.close();
                    }catch(Exception e){
                        System.out.println(e);
                    }
                }

            }

的hibernate.cfg.xml

        <?xml version="1.0" encoding="utf-8"?>
        <!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        </hibernate-configuration>

Answer 1

我认为你错放了＆＃34; name＆＃34;的实际价值。属性＆＃34;列＆＃34;属性。

＆＃34;名称＆＃34; attribute表示POJO类的属性。

＆＃34;柱＆＃34; attribute表示表的列名。

试试这个：

<hibernate-mapping>
<class name="com.program.User" table="user">
    <id name="id" type="int" column="ID">
        <generator class="increment" />
    </id>
    <property name="name" type="java.lang.String" column="NAME"></property>
    <property name="age" type="int" column="AGE"></property>
</class>
