开发环境
使用IDEA，利用Maven管理项目，整合SSM框架搭建书籍管理系统
- IntelliJ IDEA 2021.1.1
- JDK：1.8.0
- MySQL：8.0.21 可视化工具：Navicat Premium 15
- SpringVersion:5.0.2.RELEASE
- Maven 3.3.9
- Apache-tomcat-9.0.37
完整工程结构
Java代码部分
此项目需要的SQL建表语句
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
-- ----------------------------
-- Table structure for paper

CREATE TABLE `paper` (

SET FOREIGN_KEY_CHECKS = 1;
首先在src/main/java目录下新建几个包分别为：
- controller：代表控制层，此层业务层与视图层打交道的中间层，负责传输VO对象和调用BO层的业务方法，负责视图层请求的数据处理后响应给视图层.
- dao：代表数据访问对象的意思,负责持久层的操作,定义接口，包含与数据库进行交互的功能.
- pojo： 存放自定义的java类 如：paper类等，每个类的属性设为private，并提供public属性的getter/setter方法让外界访问.
- service：定义接口，包含系统所提供的功能.
- test：这里放一些测试类，可加可不加.

新建 Paper 实体类-设置私有属性-Getter And Setter没啥好说的一键生成即可
Paper
package com.liu.pojo;
/**
* Create with IDEA
*
* @ClassName: Paper
* @Author : Liu Xingyu
* @Create: 6/4/2021
* @Description: Paper实体类
*/
public class Paper {
private long paperId;
private String paperName;
private int paperNum;
private String paperDetail;
public long getPaperId() {
return paperId;
}
public void setPaperId(long paperId) {
this.paperId = paperId;
}
public String getPaperName() {
return paperName;
}
public void setPaperName(String paperName) {
this.paperName = paperName;
}
public int getPaperNum() {
return paperNum;
}
public void setPaperNum(int paperNum) {
this.paperNum = paperNum;
}
public String getPaperDetail() {
return paperDetail;
}
public void setPaperDetail(String paperDetail) {
this.paperDetail = paperDetail;
}
}
service
PaperService
在service包中新建PaperService接口
package com.liu.service;
import com.liu.pojo.Paper;
import java.util.List;
public interface PaperService {
// 查找所有
List<Paper> queryAllPaper();
// 添加
int addPaper(Paper paper);
// 根据ID删除
int deletePaperById(long id);
// 更新
int updatePaper(Paper paper);
// 根据ID查找
Paper queryById(long id);
}
PaperServiceImpl
实现前面 PaperService 接口
package com.liu.service;
import com.liu.pojo.Paper;
import com.liu.dao.PaperDao;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class PaperServiceImpl implements PaperService {
@Autowired
private PaperDao paperDao;
@Override
public int addPaper(Paper paper) {
return paperDao.addPaper(paper);
}
@Override
public int deletePaperById(long id) {
return paperDao.deletePaperById(id);
}
@Override
public int updatePaper(Paper paper) {
return paperDao.updatePaper(paper);
}
@Override
public Paper queryById(long id) {
return paperDao.queryById(id);
}
@Override
public List<Paper> queryAllPaper() {
return paperDao.queryAllPaper();
}
}
dao
PaperDao
package com.liu.dao;
import com.liu.pojo.Paper;
import java.util.List;
public interface PaperDao {
int addPaper(Paper paper);
int deletePaperById(long id);
int updatePaper(Paper paper);
Paper queryById(long id);
List<Paper> queryAllPaper();
}
controller
在controller包中新建
PaperController
package com.liu.controller;
import com.liu.pojo.Paper;
import com.liu.service.PaperService;
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 java.util.List;
/**
* Create with IDEA
*
* @ClassName: PaperController
* @Author : Liu Xingyu
* @Create: 6/4/2021
* @Description:
*/
@Controller
@RequestMapping("/paper")
public class PaperController {
@Autowired
private PaperService paperService;
@RequestMapping("/allPaper")
public String list(Model model) {
List<Paper> list = paperService.queryAllPaper();
model.addAttribute("list", list);
return "allPaper";
}
@RequestMapping("toAddPaper")
public String toAddPaper() {
return "addPaper";
}
@RequestMapping("/addPaper")
public String addPaper(Paper paper) {
paperService.addPaper(paper);
return "redirect:/paper/allPaper";
}
@RequestMapping("/del/{paperId}")
public String deletePaper(@PathVariable("paperId") Long id) {
paperService.deletePaperById(id);
return "redirect:/paper/allPaper";
}
@RequestMapping("toUpdatePaper")
public String toUpdatePaper(Model model, Long id) {
model.addAttribute("paper", paperService.queryById(id));
return "updatePaper";
}
@RequestMapping("/updatePaper")
public String updatePaper(Model model, Paper paper) {
paperService.updatePaper(paper);
paper = paperService.queryById(paper.getPaperId());
model.addAttribute("paper", paper);
return "redirect:/paper/allPaper";
}
}
@Autowired 注释，它可以对类成员变量、方法及构造函数进行标注，完成自动装配的工作。 通过 @Autowired的使用来消除 set ，get方法。
@RequestMapping 来映射请求，也就是通过它来指定控制器可以处理哪些URL请求。
resources部分
在src/main/resources下新建两个文件夹 mapper 和 spring

到这里就是所有的代码了
最后配置Tomcat就可以启动了
有可能出现的错误
第二个页面报错 500
可能是数据库版本低，我的是8.0.21；然后在jdbc.properties里，将jdbc.driver改成com.mysql.cj.jdbc.Driver，加个cj；然后在jdbc.url的链接后面加上&useSSL=false&serverTimezone=UTC
