复制提示
1.1 需求
在web工程的基础上实现ssh工程的创建，规范依赖管理。
1.2 数据库环境
使用之前学习hibernate创建的数据库：
1.3 创建父工程
选择创建Maven Project
点击next，进入下一个页面。在这个页面中选中create a simple project，这样创建的工程就会给我们自动生成目录。
点击next，进入下一个页面。注意此处：packaging类型为pom类型。
点击finish，完成父工程的创建。
1.4 定义父工程的pom.xml
maven工程首先要识别依赖，web工程实现SSH整合，需要依赖struts2.3.24、 spring4.2.4、hibernate5.0.7等，在pom.xml添加工程如下依赖：
分两步：
1）锁定依赖版本
2）添加依赖

注意：此处的pom.xml的内容读者可以直接复制使用便可以满足ssh框架所需要的全部jar包，但是这里面的<modules>标签的内容应该根据用户创建的子模块来定。读者可以不用将<modules>标签的内容粘贴进去，在创建子模块的时候，pom.xml会自动填写<modules>标签中的值。
1.5 dao1.5.1 创建ssh-dao子模块
创建Maven Module:
点击next进入下一个页面。选中create a simple project，子模块的名称为ssh-dao，父工程通过点击Browse按钮，然后选择ssh-parent.
点击next，进入下一个页面。这里由于dao层并不是web项目，所以packaging类型为jar类型。
点击finish即完成子模块的创建。
1.5.2 需求
在src/main/java中定义dao接口，实现查询全部用户的信息。
1.5.3 包结构
基本方法放在src/main/java中：
配置文件放在src/main/resources中：
test文件放在src/test/java中：
1.5.4 domain模型类
在src/main/java创建模型类：
package com.huida.domain;import java.io.Serializable;public class User implements Serializable{ /*
* 持久层规范
* po对象：（Persisent Object 持久化对象）
* 1.共有类
* 2.私有属性
* 3.公有的getter和Setter
* 4.不能使用final修饰
* 5.提供默认的无参构造
* 6.如果是基本类，就写它对应的包装类
* 7.一般都要事先java.io.Serialiable
*/
Integer uid;
String username;
String password;
public Integer getUid() {
return uid;
}
public void setUid(Integer uid) {
this.uid = uid;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}}
持久层规范
* po对象：（Persisent Object 持久化对象）
* 1.共有类
* 2.私有属性
* 3.公有的getter和Setter
* 4.不能使用final修饰
* 5.提供默认的无参构造
* 6.如果是基本类，就写它对应的包装类
* 7.一般都要事先java.io.Serialiable
1.5.5 dao接口函数
package com.huida.dao;import java.util.List;import com.huida.domain.User;public interface UserDao { /*
* 查询出user表中的所有记录
*/
public List<User> findAll();
}
1.5.6 dao实现函数
package com.huida.daoimpl;import java.util.List;import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;import com.huida.dao.UserDao;
import com.huida.domain.User;public class UserDaoImpl implements UserDao { SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
} @Override
public List<User> findAll() { Session session=sessionFactory.openSession();
Query query=session.createQuery("from User");
return query.list();
}}
1.5.7 配置文件
1.5.7.1 User.hbm.xml
在 src/main/resources创建com.huida.domain包，在改包下创建user对应的配置文User.hbm.xml。（因为User.hbm.xml要与我们的user类在同一包下，所以我们也就需要在src/main/resources创建com.huida.domain包）

1.5.7.4 log4j.properties
在src/main/resources配置log4j.properties
### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.logger.org.hibernate.type=TRACEs
1.5.8 单元测试
在src/test/java创建单元测试类
package com.huida.test;import java.util.List;import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;import com.huida.dao.UserDao;
import com.huida.domain.User;public class UserTest { @Test
public void testFindAll() {
ApplicationContext ac=new ClassPathXmlApplicationContext("classpath:applicationContext-dao.xml");
UserDao userDao=(UserDao) ac.getBean("userDao");
List<User> list=userDao.findAll();
System.out.println(list.size());
}
}
1.6 service1.6.1 创建ssh-service子模块
创建过程见ssh-dao的创建过程，同样由于service模块不是web工程，所以packaging类型也应该为jar类型。
1.6.2 在pom.xml中以jar的形式引入dao层
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

1.6.3 包结构
1.6.4 service接口函数
package com.huida.service;import java.util.List;import com.huida.domain.User;public interface UserService { public List<User> findAll();
}
1.6.5 service实现函数
package com.huida.serviceimpl;import java.util.List;import com.huida.dao.UserDao;
import com.huida.domain.User;
import com.huida.service.UserService;public class UserServiceImpl implements UserService{ private UserDao userDao; public void setUserDao(UserDao userDao) {
this.userDao = userDao;
} @Override
public List<User> findAll() { return userDao.findAll();
}}
1.6.6 配置文件
在applicationContext-service.xml中配置service
在这里注意一定要写：<import resource="classpath:applicationContext-dao.xml"></import>才可以将dao层的配置文件引入到service层。
<?xml version="1.0" encoding="UTF-8"?>

}
}
1.7 action1.7.1 创建ssh-web子模块
创建Maven Module
点击next进入下一个页面。选中create a simple project，父工程选为ssh-parent.
点击next，进入下一个页面。由于ssh-web是一个Web工程，所以packaging类型应该选为war。
点击finish完成工程的创建。
1.7.2 创建web.xml
由于这是一个web工程，所以需要创建web.xml。在Deployed Resources文件夹下的webapp包下创建WEB-INF包，在这个包下创建web.xml。
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

1.7.7 JSP文件
在Deployed Resources文件夹下的webapp包下创建suc.jsp。
<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
执行成功了
</body>
</html>
1.7.8 测试与调试
将ssh-Web子模块部署到tomcat服务器上，然后启动服务器，在浏览器中输入:http://localhost:8080/ssh-web/userAction_execute。
可以在浏览器上看到页面跳转到sus.jsp页面，并输出"执行成功了"，同时在控制台输出“2”,也就是访问数据库成功，数据库中记录条数为2条。这样三层便打通了。
