Question

我正在尝试运行hibernate应用程序，但发生异常..这是我的代码..任何建议..提前感谢

hibernate.cfg.xml：

<?xml version='1.0' encoding='utf-8'?>
<hibernate-configuration>

<session-factory>

<!-- Related to the connection START -->
<property name="connection.driver_class">com.mysql.jdbc.Driver </property>
<property name="connection.url">jdbc:mysql://localhost:3306/mydb </property>
<property name="connection.user">root </property>
<property name="connection.password">root</property>
<!-- Related to the connection END -->

<!-- Related to hibernate properties START -->
<property name="show_sql">true</property>
<property name="dialet">org.hibernate.dialect.MYSQLDialect</property>
<property name="hbm2ddl.auto">create</property>
<!-- Related to hibernate properties END-->

<!-- Related to mapping START-->
<mapping resource="user.hbm.xml" />
<!-- Related to the mapping END -->

</session-factory>
</hibernate-configuration>

user.hbm.xml：

<?xml version="1.0" encoding="UTF-8"?>
<hibernate-mapping>

<class name="DataProvider" table="user_info">

<id name="user_id" column="id">
<genereator class="assigned" />
</id>

<property name="vuser_name" column="name"/>
<property name="user_address" column="address"/>
</class>

</hibernate-mapping>

DataProvider.java：

public class DataProvider {
    private int user_id;
    private String user_name;
    private String user_address;
    public int getUser_id() {
        return user_id;
    }
    public void setUser_id(int user_id) {
        this.user_id = user_id;
    }
    public String getUser_name() {
        return user_name;
    }
    public void setUser_name(String user_name) {
        this.user_name = user_name;
    }
    public String getUser_address() {
        return user_address;
    }
    public void setUser_address(String user_address) {
        this.user_address = user_address;
    }


}

DataInsertion.java：

public class DataInsertion {

    public static void main(String[] args) {
        new DataInsertion().insertInfo();

    }

    public void insertInfo(){
        Configuration con = new Configuration();
        con.configure("hibernate.cfg.xml");
        SessionFactory sf = con.buildSessionFactory();
        Session session = sf.openSession();

        DataProvider provider = new DataProvider();
        provider.setUser_id(121);
        provider.setUser_name("name");
        provider.setUser_address("adress");

        Transaction tr = (Transaction) session.beginTransaction();
        session.save(provider);
        System.out.println("Object Saved");
        try {
            tr.commit();
        } catch (SecurityException | HeuristicMixedException | HeuristicRollbackException | RollbackException
                | SystemException e) {
            e.printStackTrace();
        }
        session.close();
        sf.close();


    }

}

你的user.hbm.xml中有一个拼写错误。你写了＃34; genereator＆＃34;而不是＆＃34; generator＆＃34;。修复它，它应该工作。

运行hibernate应用程序
