我配置了hibernate ,并生成实体类,但是在操作数据时,感觉生成的语句很奇怪都不像正常的语句的。
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>
<session-factory name=”test”>
<property name=”hibernate.connection.driver_class”>com.mysql.jdbc.Driver</property>
<property name=”hibernate.connection.password”>root</property>
<property name=”hibernate.connection.url”>jdbc:mysql://localhost:3306/test</property>
<property name=”hibernate.connection.username”>root</property>
<property name=”hibernate.default_catalog”>test</property>
<property name=”hibernate.default_schema”>test</property>
<property name=”hibernate.dialect”>org.hibernate.dialect.MySQLDialect</property>
<property name=”show_sql”>true</property>
<mapping resource=”com/medical/model/Test.hbm.xml”/>
</session-factory>
</hibernate-configuration>

Test.java:
package com.medical.model;

// Generated 2015-6-21 22:55:21 by Hibernate Tools 3.4.0.CR1

/**

public class Test implements java.io.Serializable {

private String test;

public Test() {
}

public Test(String test) {
this.test = test;
}

public String getTest() {
return this.test;
}

public void setTest(String test) {
this.test = test;
}

}

MyResource.java:
Test t=new Test();
Configuration config = new Configuration().configure();
SessionFactory sessionFactory=config.buildSessionFactory();
Session session=sessionFactory.openSession();
t.setTest(“abc”);
//TestHome th=new TestHome();
//th.attachDirty(t);
session.beginTransaction(); //启动事务
//session.save(t);
session.save(t);//.saveOrUpdate(t);
session.getTransaction().commit(); //提交事务
return “Got it!”;

感觉生成的构思sql语句相当奇怪:””.test (test) values (“”abc””)””

40分

cfg 文件中catalog ,schema 去掉,加入hibernate .format sql 设为true .针对此问题,没必要的属性不需要加入。确保jar 以及测试类没有问题。你在试试吧。
