商铺项目（项目设计和框架搭建）

系统功能模块划分：

实体类设计（注意使用包装类，因为基础类型有默认值，而不是null）与表创建：

实体类：

package com.ouyan.o2o.entity;

import java.util.Date;

public class Area {
    private Long areaId;
    private String areaName;
    private String areaDesc;
    private Integer priority;
    private Date createTime;
    private Date lastEditTime;

    public Long getAreaId() {
        return areaId;
    }

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

    public String getAreaName() {
        return areaName;
    }

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

    public String getAreaDesc() {

    }

 实体类和表的设计已经完成了。

接下来，配置Maven：

新建两个源文件：

然后在web-app下新建一个folder，命名为：resources，用于存放静态资源。（注意WEB-INF下的文件是无法直接访问的）

创建如下package：

接下来配置pom.xml（注意如果没有<scope></scope>的话，默认是compile），也就是依赖包：

另外注意：这个是给填充值。

Spring需要八个jar包，此外还依赖三个jar：和

继续完成配置文件：

在src/main/resources目录下新建jdbc.properties文件（注意useUnicode=true是因为需要存储中文）：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/o2odb?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=admin

这样我们的程序就和mysql能够通讯了。

    <!-- 配置SpringMVC -->
    <!-- 1.开启SpringMVC注解模式 -->
    <!-- 简化配置： (1)自动注册DefaultAnootationHandlerMapping,AnotationMethodHandlerAdapter 
        (2)提供一些列：数据绑定，数字和日期的format @NumberFormat, @DateTimeFormat, xml,json默认读写支持 -->
    <mvc:annotation-driven />

    <!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理：js,gif,png (2)允许使用"/"做整体映射 -->
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <mvc:default-servlet-handler />

    <!-- 3.定义视图解析器 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/html/"></property>

        <property name="defaultEncoding" value="utf-8"></property>
        <property name="maxUploadSize" value="10485760000"></property><!-- 最大上传文件大小 -->
        <property name="maxInMemorySize" value="10960"></property>
    </bean>
    <!-- 在spring-mvc.xml文件中加入这段配置后，spring返回给页面的都是utf-8编码了 -->
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">

    <!-- 4.扫描web相关的bean -->

下面测试一下：

<?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.ouyan.o2o.dao.AreaDao">
    <select id="queryArea" resultType="com.ouyan.o2o.entity.Area">
        SELECT
        area_id,
        area_name,
        priority,
        create_time,
        last_edit_time
        FROM
        tb_area
        ORDER BY
        priority DESC
    </select>
</mapper>

 

package com.ouyan.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
 * @author think
 *
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring/spring-dao.xml"})
public class BaseTest {

}

package com.ouyan.o2o.dao;

import static org.junit.Assert.assertEquals;

import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

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

public class AreaDaoTest extends BaseTest{
    @Autowired
    private AreaDao areaDao;
    
    @Test
    public void testQueryArea(){
        List<Area> areaList = areaDao.queryArea();
        assertEquals(2,areaList.size());
    }
}

右键Run as ------->JUnit Test

到此dao验证结束！

接下来验证service：

package com.ouyan.o2o.service;

import java.util.List;

import com.ouyan.o2o.entity.Area;

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

package com.ouyan.o2o.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.ouyan.o2o.dao.AreaDao;
import com.ouyan.o2o.entity.Area;
import com.ouyan.o2o.service.AreaService;

@Service
public class AreaServiceImpl implements AreaService{
    @Autowired
    private AreaDao areaDao;
    @Override
    public List<Area> getAreaList() {
        // TODO Auto-generated method stub
        return areaDao.queryArea();
    }
    
}

做下修改：

package com.ouyan.o2o.service;

import static org.junit.Assert.assertEquals;

import java.util.List;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

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

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

然后测试。

package com.ouyan.o2o.web.superadmin;

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

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 com.ouyan.o2o.entity.Area;
import com.ouyan.o2o.service.AreaService;

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

    @RequestMapping(value = "/listarea", method = RequestMethod.GET)
    @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("errMs", e.toString());
        }
        return modelMap;
    }

}
