idea搭建SSM项目（基于maven）

 

 

前言

博客描述：

本内容是基于idea和maven的一个SSM项目搭建的demo。创建项目时，记得联网（很重要）。

首先需要确定你的idea的maven，java环境是否正常。如下：

1 、创建项目

 

在上一步，点击Finish。完成创建。

2、完善目录结构

操作：选中main文件夹，创建Directory。并标记为相应的文件夹类型。

 

第一步：创建文件夹（目录）

选中main文件夹，使用快捷键（alt + inseert），使用键盘上、下键选中Dieectory。点击创建（名字分别是java、resources、test）。

第二步：标记指定的目录类型

标记成功时：发现头标，颜色发生了变化。

第三步：配置mysql数据库（可以不配）

本人建议，配置上，因为很好用，可以当做Nativcat来用，而且提示很多。（谁用谁知道）

 

到这里，如果测试成功，那恭喜你，配置好了。Apply -> ok 就可以去使用了。

第四步：pom.xml文件

第5步：数据库和表

-- auto-generated definition
create table user
(
  id       int auto_increment comment 'id'
    primary key,
  name     varchar(50)  not null comment '名字',
  password varchar(64)  not null comment '密码',
  birthday bigint(13)   null comment '生日（long类型，存储毫秒数）',
  info     varchar(255) null comment '备注'
);

第6步：java代码

• org.feng.entity

package org.feng.entity;

/**
 * Created by Feng on 2019/10/18 10:07
 * CurrentProject's name is ssm-demo
 */
public class User {
    private Integer id;
    private String name;
    private String password;
    private Long birthday;
    private String info;

    public User() {
    }

    public User(Integer id, String name, String password, Long birthday, String info) {
        this.id = id;
        this.name = name;
        this.password = password;
        this.birthday = birthday;
        this.info = info;
    }

    public Integer getId() {
        return id;
    }

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

    }

    public void setName(String name) {
        this.name = name;
    }

    }

    public void setInfo(String info) {
        this.info = info;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", password='" + password + '\'' +
                ", birthday=" + birthday +
                ", info='" + info + '\'' +
                '}';
    }

• resources/applicationContext-dao.xml

• resources/applicationContext-service.xml

• resources/applicationContext-transaction.xml

• resources/springmvc.xml

• resources/mybatis/sqlMapConfig.xml

• resources/org/feng/mapper/UserMapper.xml

此文件是对应了mybatis框架中的与Mapper接口对应的文件，在配置扫描包时，也是配置了它的路径。

    
    
        select id, name, birthday, info from user
    

第8步：index.jsp页面和web.xml文件

• web.xml文件

  Archetype Created Web Application

  
  
    contextConfigLocation
    classpath:applicationContext-*.xml
  

  
  
    log4jConfigLocation

    DispatcherServlet
    *.action
  

  
  
    DruidStatView
    /druid/*
  

  
  
    index.action
  

• index.jsp页面

本页面进行测试。

<%@ page contentType="text/html;charset=UTF-8"%>
<%@ page isELIgnored="false" %>


    
Hello World!
    

        ${sessionScope.userList}
    

第9步：配置Tomcat

第10步：运行Tomcat测试
