SSM項目搭建--數據庫的增刪改查

文章目錄

本文章將介紹如何搭建一個簡單的基於SSM的Java項目。

配置環境

IntelliJ IDEA 2019.2
Maven 3.6.1
jdk 1.8
tomcat 7.0
mysql 5.5

創建項目

打開IDEA，右側選擇Maven–導入jdk包–選擇“Create from archetype”–選擇webapp–下一步。
如果右側沒有Maven選擇，可能是沒有破解–>破解IDEA請移步
GroupId和ArtifactId填寫無要求
選擇自己安裝好的Mevan庫的路徑。
選擇1按鈕，如果.m2文件下沒有setting.xml文件，就選擇安裝Maven目錄下的conf下的setting.xml文件。選擇2的“+”，新建一個Mevan Property。設置Name爲archetypeCatalog，Value爲internal。點擊下一步。
填寫項目名和所存放的文件夾，點擊“finsh”完成maven工程的創建。
進入該工程後，將會進行自動配置導包。選擇Enable Auto-import進行自動導包。若出現BUILD SUCCESS代表項目創建成功。

項目結構和源代碼

項目結構如下：紅色標記的爲代碼部分，我會給出所有代碼，並給出相關解釋

源代碼獲取路徑：
鏈接：https://pan.baidu.com/s/1A8O1crBFsq_XhUun2gWNJw
提取碼：qmu3
複製這段內容後打開百度網盤手機App，操作更方便哦

項目結構

mysql中的表結構

表名爲userinfo，表結構如下：

Userinfo類

package com.suelta.bean;

public class Userinfo {
    private int id;
    private String username;
    private String password;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "Userinfo{" +
                "id=" + id +
                ", username='" + username + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

UserController 類

package com.suelta.controller;

import com.suelta.bean.Userinfo;
import com.suelta.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
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 org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.util.List;

//決定跳轉到哪裏
@Controller //Spring註解，相當於servlet的作用
@RequestMapping("user")
public class UserController {

    @Autowired
    private IUserService userService;

    @RequestMapping("/findAll.do")
    public ModelAndView findAll(){
        List<Userinfo> userinfos = userService.findAll();
        ModelAndView mv = new ModelAndView();	//用來傳數據給前端，也就是jsp文件
        mv.addObject("ui",userinfos);
        mv.setViewName("allUser");
        return mv;
    }

    @RequestMapping(value = "/save.do", method = RequestMethod.POST)
    public String addUser(HttpServletRequest request, HttpSession session,Userinfo userinfo){
        userService.addUser(userinfo);
        return "redirect:/user/findAll.do"; //重定向
    }

    @RequestMapping("toAddUser")
    public String toAddUser(){
        return "addUser";  
    }
    @RequestMapping("toUpdate")
    public String toUpdate(Model model,Long id){
        model.addAttribute("userInfo",userService.findOne(id)); //往前臺傳數據
        return "updateUser";   
    }

    @RequestMapping(value = "/update.do", method = RequestMethod.POST)
    public String updateUser(Model model,Userinfo userinfo){    
        userService.update(userinfo);
        return "redirect:/user/findAll.do";
    }

    @RequestMapping("/delete.do")
    public String deleteUser(Long id){  
        userService.deleteUser(id);
        return "redirect:/user/findAll.do";
    }
}

IUserDao 接口

package com.suelta.dao;

import com.suelta.bean.Userinfo;

import java.util.List;

public interface IUserDao {
    public List<Userinfo> findAll();
    public Integer addUser(Userinfo userinfo);
    public Integer deleteUser(Long id);
    public Integer updateUser(Userinfo userinfo);
    public Userinfo findOne(Long id);
}

UserServiceImpl 類

package com.suelta.service.impl;

import com.suelta.bean.Userinfo;
import com.suelta.dao.IUserDao;
import com.suelta.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements IUserService {

    @Autowired
    IUserDao userDao;
    @Override
    public List<Userinfo> findAll() {
        return userDao.findAll();
    }

    @Override
    public Integer addUser(Userinfo userinfo) {
        return userDao.addUser(userinfo);
    }

    @Override
    public Integer deleteUser(Long id) {
        return userDao.deleteUser(id);
    }

    @Override
    public Integer update(Userinfo userinfo) {
        return userDao.updateUser(userinfo);
    }

    @Override
    public Userinfo findOne(Long id) {
        return userDao.findOne(id);
    }
}

IUserService 接口

package com.suelta.service;

import com.suelta.bean.Userinfo;

import java.util.List;

public interface IUserService {
    public List<Userinfo> findAll();
    public Integer addUser(Userinfo userinfo);
    public Integer deleteUser(Long id);
    public Integer update(Userinfo userinfo);
    public Userinfo findOne(Long id);

使用tomcat啓動項目

在頂部找到run->Edit Configurations

進入環境配置後，點擊左上角的"+"->tomcat->local
填寫name(如tomcat7)->選擇configure
在Tomcat Home中選擇安裝的tomcat所在的文件，點擊ok
選擇Deplogment->點擊右側的“+”號->選擇Artficat…
選擇exploded包，點擊ok。
7. 到此配置完tomcat環境，在index.jsp頁面右鍵run即可。
