Eclipse-建立一個Dynamic Web Project,目錄結構如下:

包結構功能說明:
(1)entity包:放置項目中的實體類(一個表一個類)
(2)util工具包:各種工具類(StringHelper類)
----------M層-----------
(3)dao接口包:各種操作接口類(ICRM_UserDao)
(4)dao.impl 實作接口包:各種實作操作接口的實作類(CRM_UserDaoImpl)
(5)service接口包:業務實作的接口(ICRM_UserService)
(6)service.impl實作業務接口的實作類(CRM_UserServiceImpl)
(7)controller包:控制器實作類(CRM_UserController)(C層)
架構項目包之間的引用關系:
使用者請求-->controller-->service包-->dao包-->db
搭建ssh架構
1.下載下傳SpringMVC和Hibernate架構:Spring架構和SpringMVC架構,他們是天然內建。
springmvc官網http://projects.spring.io/spring-framework/改版後不可以直接下載下傳,可利用maven下載下傳,或者去csdn或github上下載下傳
hibernate下載下傳位址:http://hibernate.org/orm/downloads/
線上安裝SpringMVC插件
http://dist.springsource.com/release/TOOLS/update/e4.4/
線上安裝Hibernate Tools插件
http://download.jboss.org/jbosstools/neon/stable/updates/

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

</context:component-scan>
5.3配置資料源
<!-- 配置資料源 -->

<!-- 配置Hibernate的事務管理器 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
6.SSH整合測試
6.1建立test測試包
6.2建立一個Junit測試類
(test包右擊-new -other-JUnit-JUnit Test Case-TestSSH)
package com.myFlows.test;
import static org.junit.Assert.*;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestSSH {
@Test
public void test() {
fail("Not yet implemented");
}
private ApplicationContext ctx = null;
@Test
public void testDataSource() {
ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
System.out.println(ctx);
}
}
運作測試一下:
備注1:報錯Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception i...
經檢查是配置檔案applicationContext.xml檔案的hibernate 的版本不對,去網上下載下傳了hibernate-release-4.3.11.Final.zip這個版本,把以前5版本的jar包替換成4版本的,解決問題。
備注2:報錯java.sql.SQLException: The server time zone value '�й���ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
解決方法:db.properties檔案中jdbc.jdbcUrl=jdbc:mysql://localhost:3306/myflow改為jdbc.jdbcUrl=jdbc:mysql://localhost:3306/myflow?serverTimezone=UTC ,解決問題
最終正确運作:
6.3測試資料源
@Test
public void testDataSource() {
ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
System.out.println(ctx);
DataSource datasource=ctx.getBean(DataSource.class);
System.out.println(datasource);
try {
System.out.println(datasource.getConnection().toString());
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
運作結果:
6.4測試SessionFactory
SessionFactory sessionFactory= ctx.getBean(SessionFactory.class);
System.out.println(sessionFactory);
運作結果:
[email protected]
6.5測試操作資料庫表(session)
根據資料庫表寫實體類:(User.java為例)
注:表中屬性id為自動生成的,故設定alter table `user` change `id` `id` int auto_increment
其中構造函數可以用點選Source->Generate Constructor using Fields....自動生成
get函數和set函數可以用點選Source->Generate Getters and Setters.....自動生成
package com.myFlows.entity;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
//注解實體類,資料庫表名為user
@Entity
@Table(name="user")
public class User implements Serializable{
//注解id表示自動生成的
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;
private String user_id;
private String user_pass;
private String user_name;
private String user_email;
private String user_phone;
private int created_time;
public User() {
}
public User(String user_id, String user_pass, String user_name, String user_email, String user_phone,
int created_time) {
super();
this.user_id = user_id;
this.user_pass = user_pass;
this.user_name = user_name;
this.user_email = user_email;
this.user_phone = user_phone;
this.created_time = created_time;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUser_id() {
return user_id;
}
public void setUser_id(String user_id) {
this.user_id = user_id;
}
public String getUser_pass() {
return user_pass;
}
public void setUser_pass(String user_pass) {
this.user_pass = user_pass;
}
public String getUser_name() {
return user_name;
}
public void setUser_name(String user_name) {
this.user_name = user_name;
}
public String getUser_email() {
return user_email;
}
public void setUser_email(String user_email) {
this.user_email = user_email;
}
public String getUser_phone() {
return user_phone;
}
public void setUser_phone(String user_phone) {
this.user_phone = user_phone;
}
public long getCreated_time() {
return created_time;
}
public void setCreated_time(int created_time) {
this.created_time = created_time;
}
}
TestSSH.java中添加資料庫測試
Session session= sessionFactory.openSession();
Transaction tx=session.beginTransaction();
//資料庫的操作
User user=new User("bbb","123456","zhouge","[email protected]","12344444",121);
session.save(user);
tx.commit();
session.close();
運作結果:
同時檢視資料庫表:(我多運作了幾次)
此時測試操作資料庫表成功!!!
