SSH整合（三）
前面已经配置好了spring配置文件，现在需要通过实例来验证spring和hibernate的整合是否成功。
1. 实现将用户信息保存至数据库
首先需要建立用户信息的实体类，并采用注解的方式实现与数据库的映射关系，代码如下：
package com.gyjx19e.om.bean;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
@Entity
@Table(name="USER_INFO")
public class Login {
private String id;
private String name;
private String password;
private String description;
private String groupId;
private String createDate;
private String delFlg;
public Login(){
}
public Login(String name,String password,String description,String createDate,String delFlg){
this.name = name;
this.password = password;
this.description = description;
this.createDate = createDate;
this.delFlg = delFlg;
}
@Id
@Column(name="ID",length=50)
@GeneratedValue(generator="idGenerator")
@GenericGenerator(name="idGenerator",strategy="uuid")
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@Column(name="NAME",unique=true,nullable=false,length=30)
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name="PASSWORD",nullable=false,length=30)
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
@Column(name="DESCRIPTION",length=100)
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
@Column(name="GROUP_ID",length=50)
public String getGroupId() {
return groupId;
}
public void setGroupId(String groupId) {
this.groupId = groupId;
}
@Column(name="CREATE_DATE",nullable=false)
public String getCreateDate() {
return createDate;
}
public void setCreateDate(String createDate) {
this.createDate = createDate;
}
@Column(name="DEL_FLG",nullable=false)
public String getDelFlg() {
return delFlg;
}
public void setDelFlg(String delFlg) {
this.delFlg = delFlg;
}
}
2. 需要建立业务逻辑层
接口代码：
package com.gyjx19e.om.service;
import com.gyjx19e.om.bean.Login;
public interface LoginService {
public void save(Login login);
}
实现类代码：
package com.gyjx19e.om.service.impl;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.gyjx19e.om.bean.Login;
import com.gyjx19e.om.service.LoginService;
@Service @Transactional
public class LoginServiceImpl implements LoginService{
@Resource SessionFactory sessionFactory; //注解注入
public void save(Login login) {
System.out.println("2222");
sessionFactory.getCurrentSession().persist(login);
}
}
3. 需要对上述代码进行单元测试，来确定spring和hibernate的集成是否正确
测试步骤如下：
a. 新建一个junit单元测试
右键-new-Junit Test Case- New Junit4 Test
点击click here 引入包
包名为junit.test
命名为LoginTest.java
b. 在LoginTest.java中加入
public class LoginTest{
private static LoginService loginservice;
@BeforeClass
public static void setUpBeforeClass() throws Exception{
try{
ApplicationContext act = new ClassPathXmlApplicationContext("beans.xml");
loginService = (LoginService)act.getBean("loginServiceImpl");
}catch(RuntimeException e){
e.printStackTrace();
}
}
@Test
public void save(){
loginService.save(new Login("w","w","w","w","w"));
}
@Test
public void list(){
loginService.list();
}
