详解手把手Maven搭建SpringMVC+Spring+MyBatis框架(超级详细版)

SSM（Spring+SpringMVC+Mybatis），目前较为主流的企业级架构方案。标准的MVC设计模式，将整个系统划分为显示层、Controller层、Service层、Dao层四层，使用SpringMVC负责请求的转发和视图管理，Spring实现业务对象管理, MyBatis作为数据对象持久化引擎。

一. 框架详情

Spring是一个轻量级的Java开发框架，它是为了解决企业应用开发的复杂性而创建的。Spring的用途不仅限于服务器端的开发。从简单性、可测试性和松耦合的角度而言，任何Java应用都可以从Spring中受益。 简单来说，Spring是一个轻量级的控制反转（IoC）和面向切面（AOP）的容器框架

SpringMVC属于SpringFrameWork的后续产品，分离了控制器、模型对象、分派器以及处理程序对象的角色，这种分离让它们更容易进行定制

MyBatis是一个基于Java的持久层框架。MyBatis提供的持久层框架包括SQL Maps和Data Access Objects（DAO）它消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映射，将接口和 Java映射成数据库中的记录

二. 创建Maven项目

1、Eclipse中用Maven创建项目

2、按默认Next

3、找到maven-archetype-webapp后，点击next

4、填写相应的信息，GroupID是项目组织唯一的标识符，实际对应JAVA的包的结构。ArtifactID就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。Package填了默认给你建一个包，不写也可以。

5、刚建好的目录如下

6、Maven规定必须添加以下Source Folder：

src/main/resources
src/main/java
src/test/resources
src/test/java

在这步之前最好先项目上右键选择properties，然后点击java build path，在Librarys下，编辑JRE System Library，选择workspace default jre。

7、分别修改输出路径为，对应关系如下：

8、将项目转换成Dynamic Web Project，在项目上右键Properties，在左侧选择 Project Facets。

9、设置部署时的文件发布路径，删除test的两项，因为test是测试使用，并不需要部署。

设置将Maven的jar包发布到lib下。Add -> Java Build Path Entries -> Maven Dependencies -> Finish

三. Maven引入需要的JAR包

为了代替手工使用 SqlSessionDaoSupport 或 SqlSessionTemplate 编写数据访问对象 (DAO)的代码,MyBatis-Spring 提供了一个动态代理的实现:MapperFactoryBean。这个类 可以让你直接注入数据映射器接口到你的 service 层 bean 中。当使用映射器时,你仅仅如调 用你的 DAO 一样调用它们就可以了,但是你不需要编写任何 DAO 实现的代码,因为 MyBatis-Spring 将会为你创建代理。

 五. 利用MyBatis Generator自动创建实体类、映射文件以及DAO接口

MyBatis属于一种半自动的ORM框架，所以主要的工作就是配置Mapping映射文件，但是由于手写映射文件很容易出错，所以可利用MyBatis生成器自动生成实体类、DAO接口和Mapping映射文件。这样可以省去很多的功夫，将生成的代码copy到项目工程中即可。

生成代码需要的文件和jar并建立如下目录结构：

在generatorl.xml中配置相关的数据库连接，已经数据库表：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 数据库驱动 -->
<classPathEntry location="mysql-connector-java-5.1.34.jar" />
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true" />
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!--数据库链接URL，用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://192.168.1.194:3306/noc"
userId="root" password="root">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 生成模型的包名和位置 -->
<javaModelGenerator targetPackage="com.yingjun.test.model"
targetProject="src">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成映射文件的包名和位置 -->
<sqlMapGenerator targetPackage="com.yingjun.test.mapping"
targetProject="src">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 生成DAO的包名和位置 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.yingjun.test.dao"
targetProject="src">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名 -->
<table tableName="other_list" domainObjectName="OtherList"
enableCountByExample="fasle" enableUpdateByExample="false"
enableDeleteByExample="false" enableSelectByExample="false"
selectByExampleQueryId="false" >
</table>
</context>
</generatorConfiguration>

打开CMD窗口 进入该目录结构，输入命令行：

java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite

运行完成后会生成相应的dao mapper 和model，是不是很爽。

六. 建立Service层以及conrorller层

package com.yingjun.test.service;
public interface OtherServiceI {
public String getOterList();
}

package com.yingjun.test.service;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.yingjun.test.dao.OtherListMapper;
import com.yingjun.test.model.OtherList;
import com.yingjun.test.model.OtherListDomain;
@Service
public class OtherServiceImpl implements OtherServiceI {
@Autowired
private OtherListMapper otherListMapper;
@Override
public String getOterList() {
Set<String> set=new HashSet<String>();
List<OtherList> list=otherListMapper.selectAll();
List<OtherListDomain> jsonList=new ArrayList<OtherListDomain>();
for(OtherList other:list){
String title=other.getTitle();
if(set.contains(title)){
continue;
}else{
List<OtherList> t_list=new ArrayList<OtherList>();
for(OtherList data:list){
if(title.equals(data.getTitle())){
t_list.add(data);
}
}
OtherListDomain domain=new OtherListDomain();
domain.setTitle(title);
domain.setItems(t_list);
jsonList.add(domain);
set.add(other.getTitle());
}
}
return JSON.toJSONString(jsonList, SerializerFeature.WriteMapNullValue);
}
}

package com.yingjun.test.controller;
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.ResponseBody;
import com.alibaba.fastjson.JSON;
import com.yingjun.test.service.OtherServiceI;
import com.yingjun.test.service.StockStatusServiceI;
@Controller
@RequestMapping(value = "/")
public class TSSController {
@Autowired
private OtherServiceI otherService;
@RequestMapping(value="/getOtherList",produces="text/html;charset=UTF-8" )
@ResponseBody
private String getOtherList(){
String json=otherService.getOterList();
return json;
}
}

七. 建立测试类

import java.util.List;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring.xml"})
public class TestMybatis {
@Autowired
private OtherServiceI service;
@Test
public void test() {
String list=service.getOterList();
logger.info(list);
}
}

八. 通过浏览器进行验证

http://localhost:8080/TzyjStateService/getOtherList

至此，测试成功，SSM三大框架的整合就完成了，有什么其他需求可以在此基础继续添
