用idea搭建简单ssm框架

使用的IDEA作为IDE

一 创建 Maven Project

记得是 Maven Project

groupId : testSSM

artifactId: testSSM

二 配置Pom.xml

xml version="1.0" encoding="UTF-8"?>

三  创建数据库

创建表

CREATE TABLE `tb_user` (
  `UserID` int(11) NOT NULL AUTO_INCREMENT,
  `UserName` varchar(255) DEFAULT NULL,
  `RealName` varchar(255) DEFAULT NULL,
  `Password` varchar(255) DEFAULT NULL,
  `IsLock` int(11) DEFAULT NULL,
  `CreateTime` datetime DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`UserID`),
  UNIQUE KEY `id` (`UserName`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

新增数据

四 搭建SSM分层结构

注意，创建完上面5个包后，需要进行如下操作：

选择java，然后点击Sources，java文件夹会变蓝。

同样，选择resources，然后点击 Resources， resources会出现黄色横杠。

五 添加xml配置文件

先看一下配置文件

1 web.xml

    }

    public void setIslock(Integer islock) {
        this.islock = islock;
    }

    public Date getCreatetime() {
        return createtime;
    }

    public void setCreatetime(Date createtime) {
        this.createtime = createtime;
    }
}

3 dao

package dao;

import model.User;

public interface UserMapper {
    int deleteByPrimaryKey(Integer userid);

    int insert(User record);

    int insertSelective(User record);

    User selectByPrimaryKey(Integer userid);

    int updateByPrimaryKeySelective(User record);

    int updateByPrimaryKey(User record);
}

4 controller

（由于是测试，就不在创建 service和impl层了。直接调用通过就可以了。）

package controller;

import dao.UserMapper;
import model.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

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

/**

@Controller
@RequestMapping("test")
public class TestController {

    @Autowired
    protected UserMapper service;

    @RequestMapping(value = "test.do")
    public ModelAndView test1(HttpServletRequest request, HttpServletResponse response, ModelMap mode) throws Exception {
        User u =service.selectByPrimaryKey(1);

        return new ModelAndView("test/test");
    }
}

PS: protected UserMapper service; 如果这句报错，可以无视。运行没关系。

5 创建 page

webapp  -->  test  -->  test.jsp

最后运行一下页面就可以了。
http://localhost:8080/testssm/test/test.do
