2. 集成SSH
2.1 新建 Dynamic Web Project
a. 打开 Eclipse
-> 打开 Java EE Perspective (Window -> Open Perspective -> Other... -> Java EE)
-> 打开 Package Explorer View (Window -> Show View -> Other... -> Package Explorer)
b. 新建 Project
File -> New -> Dynamic Web Project -> 输入 Project name: SSH，单击 Next
-> 修改 Default output folder: WebContent/WEB-INF/classes，单击 Finish
c. 设置项目编码 utf-8
选中 SSH -> Project -> Properties -> Resource -> Text file encoding
-> Other: UTF-8 -> Apply
d. 设置编译级别
选中 SSH -> Project -> Properties -> Java Compiler
-> 选择 Compiler compliance level: 1.5
e. 添加 JUnit 支持
选中 SSH -> Project -> Properties -> Java Build Path -> Libraries -> Add Library...
-> 选择JUnit，单击 Next -> 选择 JUnit Library version: JUnit 4 -> Finish
f. 添加 Spring, Hibernate, jdbc driver及 Apache commons的所需 jar
将需要的jar 复制到 WebContent/WEB-INF/lib 目录中
-> 选中 SSH -> Project -> Properties -> Java Build Path -> Libraries
-> 展开Web App Libraries -> 确认所需 jar 文件已在 build path 中

2.2 编写测试代码
2.2.1 新建 databean
// org.demo.bean.Person.java
package org.demo.bean;
/**
* databean:Person
* @author
* @date 2010-7-17
* @file org.demo.bean.Person.java
*/
public class Person {
private int id;
private String name;

public Person(){
}
public Person(String name){
this.name = name;
}

public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

@Override
public String toString() {
return "Person [id=" + id + ", name=" + name + "]";
}

}

2.2.2 编写 hibernate 映射文件
// org.demo.bean.Person.hbm.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"
<hibernate-mapping package="org.demo.bean">
<class name="Person" table="PERSON">
<id name="id">
<generator class="native" />
</id>
<property name="name" length="50" not-null="true"/>
</class>
</hibernate-mapping>
注：hibernate 映射文件的模板参见hibernate-distribution-3.5.3-Final
/documentation/manual/zh-CN/pdf/hibernate_reference.pdf
第5章对象/关系数据库映射基础（Basic O/R Mapping）

2.2.3 编写业务bean
// org.demo.service.PersonService.java
package org.demo.service;

import java.util.List;

import org.demo.bean.Person;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

/**
* 业务层:PersonService
* @author
* @date 2010-7-20
* @file org.demo.service.PersonService.java
*/
public interface PersonService {

/**
* 保存
* @param person
*/
public abstract void save(Person person);

/**
* 修改
* @param person
*/
public abstract void update(Person person);

/**
* 删除
* @param personId
*/
public abstract void delete(int personId);

/**
* 删除所有
*/
public abstract void deleteAll();

/**
* 获取
* @param personId
* @return
*/
@Transactional(readOnly = true, propagation = Propagation.NOT_SUPPORTED)
public abstract Person get(int personId);

/**
* 分页查询 [startRow < rowNum <= startRow + maxResult]
* @param startRow
* @param maxResult
* @return
*/
@Transactional(readOnly = true, propagation = Propagation.NOT_SUPPORTED)
public abstract List<Person> get(int startRow,int maxResult);

/**
* 获取全部
* @return
*/
@Transactional(readOnly = true, propagation = Propagation.NOT_SUPPORTED)
public abstract List<Person> getAll();

}

//org.demo.service.impl.PersonServiceImpl.java
package org.demo.service.impl;

import java.util.List;

import org.demo.bean.Person;
import org.demo.service.PersonService;
import org.hibernate.Query;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

/**
* 业务层:PersonBeanImpl
* @author
* @date 2010-7-20
* @file org.demo.service.impl.PersonServiceImpl.java
*/
@Transactional
public class PersonServiceImpl implements PersonService {

@Autowired //@Resource //[在 jdk1.6下]
private SessionFactory sessionFactory;
/**
* 保存
* @param person
*/
public void save(Person person){
sessionFactory.getCurrentSession().persist(person);
}
/**
* 修改
* @param person
*/
public void update(Person person){
sessionFactory.getCurrentSession().merge(person);
}
/**
* 删除
* @param personId
*/
public void delete(int personId){
Object bean = sessionFactory
.getCurrentSession().load(Person.class,personId);
sessionFactory.getCurrentSession().delete(bean);
}
/**
* 删除所有
*/
public void deleteAll(){
List<Person> list = getAll();
for (int i=0; i<list.size(); i++){
sessionFactory.getCurrentSession().delete(list.get(i));
}
}
/**
* 获取
* @param personId
* @return
*/
@Transactional(readOnly=true,propagation=Propagation.NOT_SUPPORTED)
public Person get(int personId){
return (Person)sessionFactory.getCurrentSession()
.get(Person.class,personId);
}
/**
* 分页查询 [startRow < rowNum <= startRow + maxResult]
* @param startRow
* @param maxResult
* @return
*/
@SuppressWarnings("unchecked")
@Transactional(readOnly=true,propagation=Propagation.NOT_SUPPORTED)
public List<Person> get(int startRow,int maxResult){
Query query = sessionFactory.getCurrentSession()
.createQuery("from Person");
query.setFirstResult(startRow);
query.setMaxResults(maxResult);
return query.list();
}
/**
* 获取全部
* @return
*/
@SuppressWarnings("unchecked")
@Transactional(readOnly=true,propagation=Propagation.NOT_SUPPORTED)
public List<Person> getAll(){
return sessionFactory.getCurrentSession()
.createQuery("from Person").list();
}
}

2.2.4 编写 Spring 配置文件
// src/beans.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>
注：Spring 配置文件的模板参见
http://static.springsource.org/spring/docs/2.5.x/reference/xsd-config.html#xsd-config-body

2.2.5 编写 JUnit 测试代码
// test.junit.PersonServiceTest.java
package test.junit;

import java.util.List;

import org.demo.bean.Person;
import org.demo.service.PersonService;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
* JUnit测试类:PersonServiceTest
* @author
* @date 2010-7-20
* @file test.junit.PersonServiceTest.java
*/
public class PersonServiceTest {

private static PersonService bean = null;

@BeforeClass
public static void setUpBeforeClass() throws Exception {
try {
ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
bean = (PersonService)ctx.getBean("personService");
} catch (Exception e){
e.printStackTrace();
}

}

@Test
public void testAllMethods(){
System.out.println("+----------save---------+");
testSave();
testGetAll();
System.out.println("+----------update-------+");
testUpdate();
testGetAll();
System.out.println("+----------get----------+");
testGet();
System.out.println("+----------getAll-------+");
testGetAll();
System.out.println("+----------delete-------+");
testDelete();
testGetAll();
System.out.println("+----------deleteAll----+");
testDeleteAll();
testGetAll();
}

@Test
public void testSave() {
bean.save(new Person("Zhangsan"));
bean.save(new Person("Lisi"));
}

@Test
public void testUpdate() {
Person person = new Person("Zhangsan_uu");
// 注：此处 id 须修改
person.setId(1);
bean.update(person);
}

@Test
public void testDelete() {
// 注：此处 id 须修改
bean.delete(1);
}

@Test
public void testDeleteAll() {
bean.deleteAll();
}

@Test
public void testGet() {
// 注：此处 id 须修改
Person person = bean.get(1);
System.out.println(person);
}

@Test
public void testGetPage(){
List<Person> list = bean.get(10,10);
for(int i=0; i<list.size(); i++){
System.out.println(list.get(i));
}
}

@Test
public void testGetAll() {
List<Person> list = bean.getAll();
for(int i=0; i<list.size(); i++){
System.out.println(list.get(i));
}
}

}

运行 testAllMethods()方法，输出如下：
+----------save---------+
Person [id=1, name=Zhangsan]
Person [id=2, name=Lisi]
+----------update-------+
Person [id=1, name=Zhangsan_uu]
Person [id=2, name=Lisi]
+----------get----------+
Person [id=1, name=Zhangsan_uu]
+----------getAll-------+
Person [id=1, name=Zhangsan_uu]
Person [id=2, name=Lisi]
+----------delete-------+
Person [id=2, name=Lisi]
+----------deleteAll----+

2.3 集成 struts2
2.3.1 引入struts2 依赖 jar
将 struts2 需要的 jar 复制到 WebContent/WEB-INF/lib 目录中
-> 选中 SSH -> Project -> Properties -> Java Build Path -> Libraries
