SSM练习小项目 简易学生管理系统
目的
在学习完SSM框架之后感觉还是不太会使用，需要做一个简单的demo来熟练巩固一下，下一步准备试着做一做仿天猫的项目
一起加油！
使用技术：
-
java基础
-
基本前端知识 【HTML JSP CSS Jquery…】
-
框架：
Spring Springmvc Mybatis
-
javaee:
tomcat servlet Filter
-
数据库：
- Mysql8.0
-
开发工具：
-
IDEA2021.1
-
Maven3.5.2
-
需求分析：
这是一个极其简单的SSM练手项目 其实就是对学生信息的增删改查
数据库搭建
DROP DATABASE IF EXISTS student;
CREATE DATABASE student DEFAULT CHARACTER SET utf8
CREATE TABLE student(
id INT(11) NOT NULL AUTO_INCREMENT,
student_id INT(11) NOT NULL UNIQUE,
NAME VARCHAR(255) NOT NULL,
age INT(11) NOT NULL,
sex VARCHAR(255) NOT NULL,
birthday DATE DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=INNODB DEFAULT CHARSET=utf8;
环境搭建
-
创建maven项目
-
点击next
输入项目名
直接finish即可 -
-
搭建项目目录结构
-
配置pom.xml

配置web.xml
配置编码过滤器和DispatcherServlet <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <!--配置编码过滤器--> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置DispatcherServlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 配置springMVC需要加载的配置文件--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-*.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <!-- <async-supported>true</async-supported>--> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 匹配所有请求 --> <url-pattern>/</url-pattern> </servlet-mapping> </web-app> -
在【spring-mybatis.xml】中完成 spring 和 mybatis 的配置：

在【spring-mvc.xml】中完成 Spring MVC 的相关配置：

在【jdbc.properties】中配置 c3p0 数据库连接池：
这里注意：还是数据库版本的问题 因为我引入的数8.0的驱动 这里<mark>jdbc.driver=com.mysql.cj.jdbc.Driver</mark>如果是5.5版本的则没有。cj而且不需要再jdbc.url中设置时区serverTimezone=UTC
jdbc.driver=com.mysql.cj.jdbc.Driver #数据库地址 jdbc.url=jdbc:mysql://localhost:3306/student?useUnicode=true&serverTimezone=UTC&characterEncoding=utf8 #用户名 jdbc.username=root #密码 jdbc.password=ROOT6562 #最大连接数 c3p0.maxPoolSize=30 #最小连接数 c3p0.minPoolSize=10 #关闭连接后不自动commit c3p0.autoCommitOnClose=false #获取连接超时时间 c3p0.checkoutTimeout=10000 #当获取连接失败重试次数 c3p0.acquireRetryAttempts=2
编写代码
编写实体类
package com.libin.entity;
import java.util.Date;
/** * @author 李斌 * @date 2021/4/16 13:29 */
public class Student {
private int id;
private int student_id;
private String name;
private int age;
private String sex;
private Date birthday;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getStudent_id() {
return student_id;
}
public void setStudent_id(int student_id) {
this.student_id = student_id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
}
编写Dao
package com.libin.dao;
import com.libin.entity.Student;
import java.util.List;
public interface StudentDao {
int getTotal();
void addStudent(Student student);
void deleteStudent(int id);
void updateStudent(Student student);
Student getStudent(int id);
List<Student> list(int start, int count);
}
然后在【resources/mapper】下创建好对应的映射文件【StudentDao.xml】：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!-- 将namespace的值设置为DAO类对应的路径 -->
<mapper namespace="com.libin.dao.StudentDao">
<!-- 查询数据条目 -->
<select id="getTotal" resultType="int">
SELECT COUNT(*) FROM student
</select>
<!-- 增加一条数据 -->
<insert id="addStudent" parameterType="Student">
INSERT INTO student VALUES(NULL, #{
student_id}, #{
name}, #{
age}, #{
sex}, #{
birthday})
</insert>
<!-- 删除一条数据 -->
<delete id="deleteStudent" parameterType="int">
DELETE FROM student WHERE id = #{
id}
</delete>
<!-- 更新一条数据 -->
<update id="updateStudent" parameterType="Student">
UPDATE student SET student_id = #{
student_id}, name = #{
name},
age = #{
age}, sex = #{
sex}, birthday = #{
birthday} WHERE id = #{
id}
</update>
<!-- 查询一条数据 -->
<select id="getStudent" resultMap="student" parameterType="int">
SELECT * FROM student WHERE id = #{
id}
</select>
<resultMap id="student" type="student">
<id column="id" property="id"/>
<result column="student_id" property="student_id"/>
<result column="name" property="name"/>
<result column="age" property="age"/>
<result column="sex" property="sex"/>
<result column="birthday" property="birthday" javaType="java.sql.Date"/>
</resultMap>
<!-- 查询从start位置开始的count条数据-->
<select id="list" resultMap="student">
SELECT * FROM student ORDER BY student_id desc limit #{
param1}, #{
param2}
</select>
</mapper>
编写业务类
先创建service接口
package com.libin.service;
import com.libin.entity.Student;
import java.util.List;
public interface StudentService {
/** * 获取到 Student 的总数 * @return */
int getTotal();
/** * 增加一条数据 * @param student */
void addStudent(Student student);
/** * 删除一条数据 * @param id */
void deleteStudent(int id);
/** * 更新一条数据 * @param student */
void updateStudent(Student student);
/** * 找到一条数据 * @param id * @return */
Student getStudent(int id);
/** * 列举出从 start 位置开始的 count 条数据 * @param start * @param count * @return */
List<Student> list(int start, int count);
}
再编写实现类：
package com.libin.service;
import com.libin.dao.StudentDao;
import com.libin.entity.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/** * @author 李斌 * @date 2021/4/16 13:29 */
@Service
public class StudentServiceImpl implements StudentService{
@Autowired
StudentDao studentDao;
public int getTotal() {
return studentDao.getTotal();
}
public void addStudent(Student student) {
studentDao.addStudent(student);
}
public void deleteStudent(int id) {
studentDao.deleteStudent(id);
}
public void updateStudent(Student student) {
studentDao.updateStudent(student);
}
public Student getStudent(int id) {
return studentDao.getStudent(id);
}
public List<Student> list(int start, int count) {
return studentDao.list(start, count);
}
}
工具类编写
package com.libin.util;
/** * @author 李斌 * @date 2021/4/16 13:29 */
public class Page {
int start; // 开始数据
int count; // 每一页的数量
int total; // 总共的数据量
public Page(int start, int count) {
super();
this.start = start;
this.count = count;
}
public boolean isHasPreviouse(){
if(start==0)
return false;
return true;
}
public boolean isHasNext(){
if(start==getLast())
return false;
return true;
}
public int getTotalPage(){
int totalPage;
// 假设总数是50，是能够被5整除的，那么就有10页
if (0 == total % count)
totalPage = total /count;
// 假设总数是51，不能够被5整除的，那么就有11页
else
totalPage = total / count + 1;
if(0==totalPage)
totalPage = 1;
return totalPage;
}
public int getLast(){
int last;
// 假设总数是50，是能够被5整除的，那么最后一页的开始就是40
if (0 == total % count)
last = total - count;
// 假设总数是51，不能够被5整除的，那么最后一页的开始就是50
else
last = total - total % count;
last = last<0?0:last;
return last;
}
// 各种 setter 和 getter
public int getStart() {
return start;
}
public void setStart(int start) {
this.start = start;
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public int getTotal() {
return total;
}
public void setTotal(int total) {
this.total = total;
}
}
业务开发 controller类编写
package com.libin.controller;
import com.libin.entity.Student;
import com.libin.service.StudentService;
import com.libin.util.Page;
import org.springframework.beans.factory.annotation.Autowired;
