javaee实验，SSM整合开发综合实例

news2025/8/8 6:49:53

由于不能使用maven管理，只能导入jar包做实验，最下面有截图展示所用到的jar包，可以自己搜索文档maven导入依赖；

SSM整合开发综合实例

实验目的：
（1）掌握SSM项目整合的原则；
（2）掌握SSM框架的整合步骤；
（3）掌握综合开发实例的实现；

实验要求：
（1）完成SSM框架的整合搭建；
（2）完成SSM项目的配置；
（3）完成相关代码的编写；
（4）完成jsp页面的编码；

实验内容：
根据给定的数据库，完成一个SSM框架的项目搭建，要求最终实现在一个页面中输入学校名称和学校人数，点击按钮，将数据插入到数据库中，要求在过程中使用SSM 框架完成。

由于配置和代码中含有路径的原因，先展示一下目录：
在这里插入图片描述
1.配置文件代码：

2.业务逻辑功能代码
实体类School.java：

package com.ldu.pojo;

public class School {
	private Integer id;
	private String name;
	private int persons;
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getPersons() {
		return persons;
	}
	public void setPersons(int persons) {
		this.persons = persons;
	}
	@Override
	public String toString() {
		return "school [id=" + id + ", name=" + name + ", persons=" + persons + "]";
	}
}

Dao层 SchoolDao.java：

package com.ldu.dao;
import org.apache.ibatis.annotations.Insert;
import org.springframework.stereotype.Repository;

@Repository
public interface SchoolDao {
	
	@Insert("insert into t_school(name, persons) values(#{param1},#{param2})")
	int InsertSchool(String name, Integer persons);
}

Service层 SchoolService.java：

package com.ldu.service;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.ldu.dao.SchoolDao;

@Service
public class SchoolService {
	
	@Resource
	private SchoolDao schoolDao;
	
	public int insertSchool(String name, Integer persons) {
		return schoolDao.InsertSchool(name, persons);
	}	
}

Controller层 SchoolController.java：

package com.ldu.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.ldu.service.SchoolService;
import com.ldu.pojo.School;

@Controller
@RequestMapping("/school")
public class SchoolController {
	
	@Resource
	private SchoolService schoolService;
	
	@RequestMapping(value="/add", method=RequestMethod.POST)
	public String add(School school,Model model) {
		if(schoolService.insertSchool(school.getName(), school.getPersons())>0) {
			model.addAttribute("msg", "添加成功！");
		}
		else {
			model.addAttribute("msg", "添加失败！");
		}
		return "msg";
	}

}

3.Jsp页面的代码：

index.jsp：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML">
<html>
<head>
  <title>新增学校</title>
</head>
  
 <body>
	<form action="${pageContext.request.contextPath }/school/add" method="post">
		校名：<input name="name"><br/>
		人数：<input name="persons"><br/>
		<input type="submit" value="新增学校">
	</form>
 </body>
</html>

msg.jsp：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<!DOCTYPE HTML">
<html>
<head>
  <title>反馈信息</title>
</head>
  
 <body>
	<h3>${msg}</h3>
 </body>
</html>
