Eclipse下SSH集成（JPA）

SSH-JPA环境搭建
JPA环境的搭建：
1. 新建Web工程
项目名：shop
ContentPath：/
2. JPA环境的搭建
文件：hibernate-distribution-3.3.2.GA-dist.zip，
hibernate-entitymanager-3.4.0.GA.zip
mysql-connector-java-5.1.12.zip
   所需Jar文件：
2.1 Hibernate的Jar文件：
hibernate3.jar，antlr-2.7.6.jar， commons-collections-3.1.jar，dom4j-1.6.1.jar，javassist-3.9.0.GA.jar，jta-1.1.jar，slf4j-api-1.5.8.jar，c3p0-0.9.1.jar，oscache-2.1.jar，
slf4j-log4j12.jar，log4j.jar
2.2 entitymanager的jar文件：
hibernate-entitymanager.jar，hibernate-annotations.jar，
hibernate-commons-annotations.jar，hibernate-core.jar，ejb3-persistence.jar
2.3 MySQL驱动包
mysql-connector-java-5.1.12-bin.jar

3. JPA配置文件
在类路径下新建文件夹META-INF，在该文件夹下新建persistence.xml文件：

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">

org.hibernate.ejb.HibernatePersistence



value="jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=UTF-8" />











4. JPA测试
4.1 新建Entity类：
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class ProductType implements Serializable {
private Integer typeId;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
public Integer getTypeId() {
return typeId;
}

public void setTypeId(Integer typeId) {
this.typeId = typeId;
}
}

4.2  新建Junit测试类：
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;

import org.junit.Test;

import cn.zlj.shop.bean.product.ProductType;

public class ProductTest {

@Test
public void testRun() {
EntityManagerFactory factory = Persistence
.createEntityManagerFactory("shop");
EntityManager em = factory.createEntityManager();
em.getTransaction().begin();
em.persist(new ProductType());
em.getTransaction().commit();
em.close();
factory.close();
}
}

4.2 运行JUnit
4.2.1 Console:
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.
Hibernate:
    insert
    into
        ProductType
       
    values
        ( )

4.2.2 MySQL数据库
mysql> use shop;
Database changed
mysql> show tables;
+----------------+
| Tables_in_shop |
+----------------+
| producttype    |
+----------------+
1 row in set (0.00 sec)

mysql> select * from producttype;
+--------+
| typeId |
+--------+
|      1 |
+--------+
1 row in set (0.00 sec)

JPA环境搭建成功。

destroy-method="close">














class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">


class="org.springframework.instrument.classloading.InstrumentationLoadTimeWeaver" />











3. 修改persistence.xml
将以下配置项删除：
hibernate.connection.driver_class,
hibernate.connection.username,
hibernate.connection.password,
hibernate.connection.url



项目源文件夹下新建文件：jdbc.properties
driverClassName= com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=UTF-8
username=root
password=root
initialSize=1
maxActive=100
maxIdle=8
minIdle=1

集成测试：

4. 业务的接口类ProductTypeService.java

public interface ProductTypeService {
public void save(ProductType type);
}

5. 业务的具体实现类ProductTypeServiceBean.java

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

@Service
@Transactional
public class ProductTypeServiceBean implements ProductTypeService {

@PersistenceContext

public void save(ProductType type) {
em.persist(type);
}
}

6. JUnit测试类ProductTest.java

public class ProductTest {
@Test
public void testRun() {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
ProductTypeService productTypeService = (ProductTypeService) ctx
.getBean("productTypeServiceBean");
productTypeService.save(new ProductType());
}
}

7. 运行JUnit测试类
log4j:WARN No appenders could be found for logger (org.springframework.context.support.ClassPathXmlApplicationContext).
log4j:WARN Please initialize the log4j system properly.
Hibernate:
    insert
    into
        ProductType
       
    values
        ( )

8. 数据库
mysql> select * from producttype;
+--------+
| typeId |
+--------+
|      1 |
|      2 |
+--------+
2 rows in set (0.00 sec)

集成成功。

config
/WEB-INF/struts-config.xml




struts
*.do


4. 在WEB-INF/中添加struts的配置文件struts-config.xml

          "http://struts.apache.org/dtds/struts-config_1_3.dtd">


value="org.springframework.web.struts.DelegatingRequestProcessor" />



5. 测试
5.1 编写控制器类: ProductTypeAction.java

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.stereotype.Controller;

import cn.shop.bean.product.ProductType;
import cn.shop.service.product.ProductTypeService;

@Controller("/control/product/type/list")
public class ProductTypeAction extends Action {

@Resource(name = "productTypeServiceBean")
private ProductTypeService productTypeService;

@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
productTypeService.save(new ProductType());
request.setAttribute("msg", "成功！！");
return mapping.findForward("success");
}

}

5.2 修改struts配置文件






5.3 在/WEB-INF/page/下，新建jsp文件message.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"%>







消息：${msg}



5.4 启动Web服务器
启动成功后，通过浏览器访问control/product/type/list.do
url: http://localhost:8080/control/product/type/list.do
浏览器输出结果：
消息：成功！！

5.5 数据库

mysql> select * from producttype;
+--------+
| typeId |
+--------+
|      1 |
|      2 |
|      3 |
+--------+
3 rows in set (0.00 sec)

集成完成。
