今天中午闲来没有事。就来熟悉了一下用Maven搭建SSH。。。。。


先上目录结构：


添加需要的jar包pom.xml:

接下来就是测试的代码：

UserAction.java：

package cn.java68.action;

import javax.annotation.Resource;

import cn.java68.model.User;
import cn.java68.service.UserService;

public class UserAction {
	
	User user;
	UserService userService;
	
	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}

	public UserService getUserService() {
		return userService;
	}

	@Resource
	public void setUserService(UserService userService) {
		this.userService = userService;
	}

	public String add() {
		userService.add(user);
		return "success";
	}
}

UserDaoImpl.java:

package cn.java68.dao.impl;

import javax.annotation.Resource;

import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Component;

import cn.java68.dao.UserDao;
import cn.java68.model.User;

@Component
public class UserDaoImpl implements UserDao{

	HibernateTemplate hibernateTemplate;
	
	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}

	@Resource
	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}

	public void add(User user) {
		// TODO Auto-generated method stub
		hibernateTemplate.save(user);
	}

}

UserDao.java:

package cn.java68.dao;

import cn.java68.model.User;

public interface UserDao {

	public void add(User user);
}

User.java:

package cn.java68.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class User {

	@Id
	@GeneratedValue(strategy=GenerationType.IDENTITY)
	private int id;
	private String 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;
	}
	
	
}

UserServiceImpl.java:

package cn.java68.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import cn.java68.dao.UserDao;
import cn.java68.model.User;
import cn.java68.service.UserService;

@Component
public class UserServiceImpl implements UserService {

	UserDao userDaoImpl;
	
	public UserDao getUserDaoImpl() {
		return userDaoImpl;
	}

	@Resource
	public void setUserDaoImpl(UserDao userDaoImpl) {
		this.userDaoImpl = userDaoImpl;
	}

	public void add(User user) {
		// TODO Auto-generated method stub

		userDaoImpl.add(user);
	}

}

UserService.java:

package cn.java68.service;

import cn.java68.model.User;

public interface UserService {

	public void add(User user);
}

index.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>

<form method="post" action="save">
	姓名：<input type="text" name="user.name">
	<br>
	<input type="submit" value="提交">
</form>
</body>
</html>

success.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>
写入成功！！！！！
</body>
</html>

最后就是创建数据库：

CREATE DATABASE test；

运行结果：
