新建一个com.imooc.o2o.entity的包
新建一个Area类，创建5个成员变量

package com.imooc.o2o.entity;

import java.util.Date;

public class Area {
    // ID
    private Integer areaId;
    // 名称
    private String areaName;
    // 权重
    private Integer priority;
    // 创建时间
    private Date createTime;
    // 更新时间
    private Date lastEditTime;

    public Integer getAreaId() {
        return areaId;
    }

    public void setAreaId(Integer areaId) {
        this.areaId = areaId;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public Integer getPriority() {
        return priority;
    }

    public void setPriority(Integer priority) {
        this.priority = priority;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }
}

使用Navicat创建数据表tb_area数据表

use o2o;
create table `tb_area`(
  `area_id` int(2) NOT NULL AUTO_INCREMENT,
  `area_name` varchar(200) NOT NULL,
  `priority` int(2) NOT NULL DEFAULT '0',
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  primary key(`area_id`),
  unique key `UK_AREA`(`area_name`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

使用InnoDB引擎，自增为1，设置默认编码格式为utf8

创建PersonInfo类

package com.imooc.o2o.entity;

import java.util.Date;

public class PersonInfo {
    private Long userId;
    private String name;
    private String profileImg;
    private String email;
    private String gender;
    private Integer enableStatus;
    // 1表示顾客  2表示店家  3表示管理员
    private Integer userType;
    private Date createTime;

    public Long getUserId() {
        return userId;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    public String getName() {
        return name;
    }

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

    public String getProfileImg() {
        return profileImg;
    }

    public void setProfileImg(String profileImg) {
        this.profileImg = profileImg;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public Integer getEnableStatus() {
        return enableStatus;
    }

    public void setEnableStatus(Integer enableStatus) {
        this.enableStatus = enableStatus;
    }

    public Integer getUserType() {
        return userType;
    }

    public void setUserType(Integer userType) {
        this.userType = userType;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }

    private Date lastEditTime;
}

创建tb_person_info数据表

use o2o;
create table `tb_person_info`(
  `user_id` int(10) NOT NULL AUTO_INCREMENT,
  `name` varchar(32) DEFAULT NULL,
  `profile_img` varchar(1024) DEFAULT NULL,
  `email` varchar(1024) DEFAULT NULL,
  `gender` varchar(2) DEFAULT NULL,
  `enable_status` int(2) NOT NULL DEFAULT '0' COMMENT '0:禁止, 1:允许',
  `user_type` int(2) NOT NULL DEFAULT '1' COMMENT '1代表顾客, 2代表商家, 3代表超级管理员',
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  primary key (`user_id`)
 )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

openId是微信号与本地账号绑定的唯一标识
新建一个WechatAuth类，用于微信登入

package com.imooc.o2o.entity;

import java.util.Date;

public class WechatAuth {
    private Long WechatAuthId;
    private String openId;
    private Date createtime;
    private PersonInfo personInfo;

    public PersonInfo getPersonInfo() {
        return personInfo;
    }

    public void setPersonInfo(PersonInfo personInfo) {
        this.personInfo = personInfo;
    }

    public Long getWechatAuthId() {
        return WechatAuthId;
    }

    public void setWechatAuthId(Long wechatAuthId) {
        WechatAuthId = wechatAuthId;
    }

    public String getOpenId() {
        return openId;
    }

    public void setOpenId(String openId) {
        this.openId = openId;
    }

    public Date getCreatetime() {
        return createtime;
    }

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

新建一个本地账号

package com.imooc.o2o.entity;

import java.util.Date;

public class LocalAuth {
    private Long localAuthId;
    private String username;
    private String password;
    private Date createTime;
    private Date lastEditTime;
    private PersonInfo personInfo;

    public Long getLocalAuthId() {
        return localAuthId;
    }

    public void setLocalAuthId(Long localAuthId) {
        this.localAuthId = localAuthId;
    }

    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;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getLastEditTime() {
        return lastEditTime;
    }

    public void setLastEditTime(Date lastEditTime) {
        this.lastEditTime = lastEditTime;
    }

    public PersonInfo getPersonInfo() {
        return personInfo;
    }

    public void setPersonInfo(PersonInfo personInfo) {
        this.personInfo = personInfo;
    }
}

创建tb_wechat_auth数据表

use o2o;
create table `tb_wechat_auth`(
  `wechat_auth_id` int(10) NOT NULL AUTO_INCREMENT,
  `user_id` int(10) NOT NULL,
  `open_id` varchar(1024) NOT NULL,
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  primary key(`wechat_auth_id`),
  constraint `fk_wechatauth_profile` foreign key(`user_id`) references `tb_person_info`(`user_id`)
  )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

创建tb_local_auth数据表

use o2o;
create table`tb_local_auth`(
  `local_auth_id` int(10) NOT NULL AUTO_INCREMENT,
  `user_id` int(10) NOT NULL,
  `username` varchar(128) NOT NULL,
  `password` varchar(128) NOT NULL,
  `create_time` datetime DEFAULT NULL,
  `last_edit_time` datetime DEFAULT NULL,
  primary key(`local_auth_id`),
  unique key `uk_local_profile`(`username`),
  constraint `fk_localauth_profile` foreign key(`user_id`) references `tb_person_info`(`user_id`)
  )ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

我们要个open_id增加一个唯一索引

alter table tb_wechat_auth add unique index(open_id);

添加索引能增加查询的性能

测试dao

向数据库中添加数据

image.png
在dao中新建AreaDao类

package com.imooc.o2o.dao;

import com.imooc.o2o.entity.Area;

import java.util.List;

public interface AreaDao {
    List<Area> queryArea();
}

在mapper文件中新建AreaDao.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.imooc.o2o.dao.AreaDao">
    <select id="queryArea" resultType="com.imooc.o2o.entity.Area">
        SELECT
        area_id,
        area_name,
        priority,
        create_time,
        last_edit_time
        FROM
        tb_area
        ORDER BY
        priority DESC
    </select>
</mapper>

如图新建基类BaseTest类

package com.imooc.o2o;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * 配置spring和junit整合，junit启动时加载springIOC容器 spring-test,junit
 */
@RunWith(SpringJUnit4ClassRunner.class)
// 告诉junit spring配置文件
@ContextConfiguration({ "classpath:spring/spring-dao.xml",
        "classpath:spring/spring-service.xml" })
public class BaseTest {

}

测试类

package com.imooc.o2o.dao;

import static org.junit.Assert.assertEquals;

import java.util.List;

import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runners.MethodSorters;
import org.springframework.beans.factory.annotation.Autowired;

import com.imooc.o2o.BaseTest;
import com.imooc.o2o.entity.Area;

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class AreaDaoTest extends BaseTest {
    @Autowired
    private AreaDao areaDao;

    @Test
    public void testBQueryArea() throws Exception {
        List<Area> areaList = areaDao.queryArea();
        assertEquals(2, areaList.size());
    }
}

测试成功

说明文件配置正确

测试service

image.png
在service目录下新建AreaService接口

package com.imooc.o2o.service;

import com.imooc.o2o.entity.Area;

import java.util.List;

public interface AreaService {
    List<Area> getAreaList();
}

在service目录下新建impl目录，用于实现service接口的实现类

新建AreaServiceImpl类

package com.imooc.o2o.service.impl;

import com.imooc.o2o.dao.AreaDao;
import com.imooc.o2o.entity.Area;
import com.imooc.o2o.service.AreaService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class AreaServiceImpl implements AreaService {

    @Autowired
    private AreaDao areaDao;

    @Override
    public List<Area> getAreaList() {
        return areaDao.queryArea();
    }
}

测试类

package com.imooc.o2o.service;

import com.imooc.o2o.BaseTest;
import com.imooc.o2o.entity.Area;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import java.util.List;

import static org.junit.Assert.assertEquals;

public class AreaServiceTest extends BaseTest {
    @Autowired
    private AreaService areaService;
    @Test
    public void testGetAreaList() {
        List<Area> areaList = areaService.getAreaList();
        assertEquals("东苑", areaList.get(0).getAreaName());
    }
}

测试成功

测试Controller

我们从超级管理员的维度来编写我的controller
新建web.superadmin包

image.png

package com.imooc.o2o.web.superadmin;

import com.imooc.o2o.entity.Area;
import com.imooc.o2o.service.AreaService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Controller
@RequestMapping("superadmin")
public class AreaController {
    @Autowired
    private AreaService areaService;

    @RequestMapping(value = "/listareas", method = RequestMethod.GET)
    // 转化为json对象
    @ResponseBody
    private Map<String, Object> listArea() {
        Map<String, Object> modelMap = new HashMap<String, Object>();
        List<Area> list = new ArrayList<Area>();
        try {
            list = areaService.getAreaList();
            modelMap.put("rows", list);
            modelMap.put("total", list.size());
        } catch (Exception e) {
            e.printStackTrace();
            modelMap.put("success", false);
            modelMap.put("errMsg", e.toString());
        }
        return modelMap;
    }
}

测试
我使用google插件Postman发送请求
路由使用下面3个组成
http://localhost:8080/project2/superadmin/listareas

SSM重点

SpringMVC：DispatcherServlet
是整个MVC框架中最核心一块，主要拦截符合要求的请求，并把请求分发到不同的控制中，根据控制器处理后的结果生成相应的响应，发送到客户端
Spring：IOC和AOP
IOC：依赖注入
AOP：面向切面编程，实现通过动态代理
MyBatis：ORM
对象关系映射(Object Relational Mapping)，将程序中的对象自动持久化到数据库
