IDEA+Maven 搭建spring-Spring Mvc-MyBatis环境

最近想把之前学过的Maven、Spring、Spring Mvc、MyBatis框架的零散的东西整合一下。正好想要和同学一起开发一个有关校园info的微信小程序。借此机会，整合一下之前的知识，顺便学习下Restful Api的构建。

一、搭建项目

1、打开IDEA新建有个项目，选择maven-archetype-webapp

2、填写groupId和artifactId

groupId：项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。
ArtifactID：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。

3、Maven home directory：填写本地Maven目录，建议更改IDE的默认设置为自己安装的Maven，其他值默认即可

4、之后IDE会自动生成一个标准的Maven Java Web项目，结构如图

5、File->Project Structure选择Model，配置文件夹的结构和属性，如图配置即可

二、配置文件

1、配置pom.xml文件，这个文件中主要配置标签

    <groupId>junitgroupId>
      <artifactId>junitartifactId>
      <version>4.12version>
      <scope>testscope>

      <groupId>org.springframeworkgroupId>
      <artifactId>spring-testartifactId>
      <version>4.3.4.RELEASEversion>
    dependency>

2、配置：spring-dao.xml

resources/spring/spring-dao.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    
    <context:property-placeholder location="classpath:jdbc.properties"/>
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        
        <property name="driverClass" value="${driver}"/>
        <property name="jdbcUrl" value="${url}"/>
        <property name="user" value="${username}"/>
        <property name="password" value="${password}"/>
        
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        
        <property name="autoCommitOnClose" value="false"/>
        
        <property name="checkoutTimeout" value="1000"/>

        <property name="dataSource" ref="dataSource"/>
        
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        
        <property name="typeAliasesPackage" value="com.neuq.info.entity;com.neuq.info.dto"/>
    bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        
        <property name="basePackage" value="com.neuq.info.dao"/>
    bean>
    beans>

3、jdbc.properties 数据库连接属性配置

resources/jdbc.properties

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

4、配置：spring-service.xml

resources/spring/spring-service.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd">

    
    <context:component-scan base-package="com.neuq.info.service"/>
    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        
        <property name="dataSource" ref="dataSource"/>
        

    bean>
    <tx:annotation-driven transaction-manager="transactionManager"/>
    beans>

5、mybatis-config.xml

<configuration>
    
    <settings>
        
        <setting name="useGeneratedKeys" value="true"/>
        
        <setting name="useColumnLabel" value="true"/>
        
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    settings>
configuration>

6、配置：spring-web.xml

resources/spring/spring-web.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    
    
    <mvc:annotation-driven />
    
   <mvc:default-servlet-handler/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    bean>

    <context:component-scan base-package="org.seckill.web"/>
    beans>

7、配置web.xml

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                      http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
         version="3.1"
         metadata-complete="true">

  <servlet>
    <servlet-name>seckill-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-*.xml</param-value>
    </init-param>
  </servlet>

  <servlet-mapping>
    <servlet-name>seckill-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  </web-app>

7、logback.xml最简单的logback配置，复杂配置可以从官方文档获取

<configuration debug="true">
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%npattern>
        encoder>
    appender>

    <root level="debug">
        <appender-ref ref="STDOUT" />
    root>
configuration>
