IntelliJ IDEA 創建Spring+SpringMVC+mybatis+mybatis項目

 參考自:https://www.cnblogs.com/hackyo/p/6646051.html

第一步: 創建maven項目

   輸入項目名和工程id

   選擇maven

   預設就可以了

  剛開始時間比較長,可以看到,用了有7分多鐘, 還是很快的

  maven包下載好後,項目結構如下

第二步： 創建java包

  可以看到, 缺少java包,在main上右鍵新建包

  建完java後的目錄

第三步：創建層級結構

  到這裡先不要修改java包的狀態, 接著創建其他目錄結構,這麼做的主要目的是方便創建分級結構。

  當改變java包的狀態後，service.impl會變成一個包的名字，這時候需要Rename以下這個包，先變成service,然後創建PersonService.java, 在創建impl包, 就好了

  如果覺得麻煩可以在創建目錄的時候先不創建impl包

  然後修改java包的狀態,右鍵java包

第四步：創建需要的文件

  接下來創建一系列的文件, 然後在進行配置,先把骨架搭起來

  以上就是所有用到的文件，現在開始一個一個文件填充， 現在的目的是搭建起來能運次的項目，如果想知道配置原理請自行查閱資料

第五步：填充文件

   被標稱黃色的部分是需要註意的, 如果更改了需要做相應的改動, 如果項目目錄跟這個一樣,就不需要改動

PersonController.java

package com.ssm.demo.controller;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.ssm.demo.entity.Person;
import com.ssm.demo.service.PersonService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Controller
@RequestMapping("/person")
public class PersonController {

    @Autowired
    private PersonService personService;
    @RequestMapping("/selectPerson")
    public void selectPerson(HttpServletRequest request, HttpServletResponse response) throws IOException {

        request.setCharacterEncoding("utf-8");
        response.setCharacterEncoding("utf-8");

        long personId = Long.parseLong(request.getParameter("id"));
        Person person =personService.findPersonById(personId);

        ObjectMapper mapper = new ObjectMapper();

        response.getWriter().write(mapper.writeValueAsString(person));
        response.getWriter().close();
    }
}

PersonMapperDao.java

package com.ssm.demo.dao;

import com.ssm.demo.entity.Person;
import org.springframework.stereotype.Repository;

@Repository
public interface PersonMapperDao {
    Person findPersonById(long id);
}

Person.java

package com.ssm.demo.entity;

public class Person {
    private long id;
    private String name;
    private String email;
    private int status;

   //getter  setter

    @Override
    public String toString(){
        return this.getId()+"---"+this.getName()+"---"+
                this.getEmail()+"---"+this.getStatus();
    }
}

PersonService.java

package com.ssm.demo.service;

import com.ssm.demo.entity.Person;

public interface PersonService {
     Person findPersonById(long id);
}

PersonServiceImpl.java

package com.ssm.demo.service.impl;

import com.ssm.demo.dao.PersonMapperDao;
import com.ssm.demo.entity.Person;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class PersonServiceImpl implements PersonService {
    @Autowired
    private PersonMapperDao personMapperDao;
    public Person findPersonById(long id) {
        return personMapperDao.findPersonById(id);
    }
}

第六步: 配置tomcat

   先clean一下, 然後package一下

  打包成功後,控制台顯示

   會多一個包,和一個war文件

  配置tomcat

  選擇deployment, 點擊右邊加號

     輸入請求的跟地址, 項目名

 
  還有一種是點擊右邊加號,可以添加artifact的, 沒弄明白怎麼整的, 求鏈接.

第七步: 資料庫創建, 表的建立, 插入數據

navicat 圖形化界面創建資料庫,然後修改jdbc.properties文件的資料庫名稱為自己創建的資料庫,然後創建表

CREATE TABLE person (
  id int(11) NOT NULL AUTO_INCREMENT,
  email varchar(255) NOT NULL,
  name varchar(255) NOT NULL,
  status int(1) NOT NULL,
  PRIMARY KEY (id),
  UNIQUE KEY email (email) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

INSERT INTO person VALUES ('1', '123456qq.com', 'zzz', '0');
SET FOREIGN_KEY_CHECKS=1;

第八步: 啟動tomcat, 彈出頁面點擊按鈕, 會出現查詢內容
