基于SSM框架学生管理系统的实现

这是我一年前做的项目的，算是SSM框架入门的实例，maven管理工具所用到的仓库私服为阿里云的仓库。

整个项目的目录：

jdbc.properties是对数据库信息的配置：

#mysql version database setting
jdbc.driver=com.mysql.jdbc.Driver
jdbc.username=root
jdbc.password=
jdbc.url=jdbc\:mysql\://127.0.0.1\:3306/test?useUnicode=true&characterEncoding=UTF-8

service-context.xml：

	Spring-database配置
	
	
		
	
	
	
		
			
				classpath*:jdbc.properties
			
		
	

	
	

	
	
		
		
		
		
		

		
		
		
		
		
		
		
	

	
	
		
		
	
	
	
	
		
	

	
		
	

	
		
			
			
			
			
			
		
	

servlet-context.xml：

	Spring-web MVC配置
	
	
	
		
	
	
	
	

	
	
	
	
	
		
		
		
		
		
		
		
		
		
		
		
		
		
		
		
	

	
		
		
		
		
		
		
			
				
				5

				
				zh_CN
			
			
		
	
	

mybatis-config.xml：

StudentMapper.xml，SQL语句编写的地方：

	
	    id,name,chinese,math,english
	
	
	
		select 
		
		from student
	
	
	
		select 
		
		from student where id = #{id}
	

	
	
		INSERT INTO student(name,chinese,math,english) VALUES (#{name}, #{chinese},#{math},#{english});
	
	
	
		update student
		
			
				name = #{name},
				chinese =#{chinese},
				math =#{math},
				english=#{english}
			
		
		where id = #{id}
	

	
		delete from student where id = #{id}
	

MyBatis的Dao基类:

package com.HelloWorld.orm.mybatis;

import java.io.Serializable;
import java.util.List;

import org.mybatis.spring.support.SqlSessionDaoSupport;

/**
 * MyBatis的Dao基类
 * @author 
 */
public class MyBatisDao extends SqlSessionDaoSupport{
	
	public void save(String key, Object object) {
		getSqlSession().insert(key, object);
	}
	
	public void delete(String key, Serializable id) {
		getSqlSession().delete(key, id);
	}

	public void delete(String key, Object object) {
		getSqlSession().delete(key, object);
	}
	

	public  T get(String key, Object params) {
		return (T) getSqlSession().selectOne(key, params);
	}
	

	public  List getList(String key) {
		return getSqlSession().selectList(key);
	}

	public  List getList(String key, Object params) {
		return getSqlSession().selectList(key, params);
	}
}

entity实体类：

package com.HelloWorld.examples.base.entity;

public class Student {
	private Integer id;
	private String name;
	private float chinese;
	private float  math;
	private float english;
	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 float getChinese() {
		return chinese;
	}
	public void setChinese(float chinese) {
		this.chinese = chinese;
	}
	public float getMath() {
		return math;
	}
	public void setMath(float math) {
		this.math = math;
	}
	public float getEnglish() {
		return english;
	}
	public void setEnglish(float english) {
		this.english = english;
	}


	
	
}

Service层

package com.HelloWorld.examples.base.service;

import java.io.Serializable;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


import com.HelloWorld.examples.base.entity.Student;
import com.HelloWorld.orm.mybatis.MyBatisDao;


@Service
public class StudentService {
	@Autowired
	private MyBatisDao myBatisDao;
	
	public List getStudent(){
		return myBatisDao.getList("StudentMapper.selectByEntity");
	}
	
	public Student getStudent(Serializable id){
		return myBatisDao.get("StudentMapper.selectByPrimaryKey",id);
	}
	
	public void save(Student student){
		   
		if(student.getId()==null)
			myBatisDao.save("StudentMapper.insert", student);
		else
			myBatisDao.save("StudentMapper.update",student);
	}

	
	public void delete(Serializable id){
		myBatisDao.delete("StudentMapper.delete", id);
	}
}

controller层：

package com.HelloWorld.examples.base.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import com.HelloWorld.examples.base.entity.Student;
import com.HelloWorld.examples.base.service.StudentService;

@Controller
@RequestMapping("/student")
public class StudentController {
	@Autowired
	private StudentService studentService;
	
	@RequestMapping(method = RequestMethod.GET)
	public String list(Model model){
		model.addAttribute("list", studentService.getStudent());
		return "base/student_list";
	}
	
	@RequestMapping(value="/new", method = RequestMethod.GET)
	public String create(Model model, Student student){
		model.addAttribute("entity",student);
		return "base/student_new";
	}
	
	@RequestMapping(value="/edit/{id}", method = RequestMethod.GET)
	public String edit(Model model, @PathVariable Integer id){
		model.addAttribute("entity", studentService.getStudent(id));
		return "base/student_edit";
	}
	
	@RequestMapping(value="/save", method = RequestMethod.POST)
	public String save(Model model, Student student){
		studentService.save(student);
		return "redirect:/student";
	}
	
	@RequestMapping(value="/view/{id}", method = RequestMethod.GET)
	public String view(Model model, @PathVariable Integer id){
		model.addAttribute("entity", studentService.getStudent(id));
		return "base/student_view";
	}
	
	@RequestMapping(value="/delete/{id}", method = RequestMethod.GET)
	public String delete(Model model, @PathVariable Integer id){
		studentService.delete(id);
		return "redirect:/student";
	}
}

执行结果：
