一篇文章学会Spring+SpringMVC+Mybatis+Maven搭建和部署，记一次Spring+SpringMVC+Mybatis+Maven的整合

之前一直没有用过maven和Mybatis最近自己搭建一个基于Maven的Spring+SpringMVC+Mybatis开发环境。

注：有的时候没有自己动手真正搭过环境（脱离教学的方式），可能有些地方的问题注意不到的。

会在介绍搭建的同时记录一些遇见的坑和一些知识点。

首先放上Maven配置文件。

1、POM.xml(至于maven里面支持的一些服务插件什么的可以自己另行百度)

注：

①、pom文件要放到项目根目录下

②、maven的文件结构

src/main/java 该source floder用来存放java代码

src/test/java 该source floder用来存放测试代码

src/main/webapp 该source floder用来存放jsp和web配置文件，相当于web项目的webroot

target 用来存放maven打包编译的文件

注：普通项目如何改为maven项目

①、将项目更改为maven结构

②、然后在该项目下执行mvn命令：mvn eclipse:eclipse 项目根目录必须有pom.xml否则maven无法生成相应目录结构

③、执行成功后在.project中相应位置添加如下配置

    <buildCommand>
      <name>org.eclipse.m2e.core.maven2Builder</name>
    </buildCommand>

    <nature>org.eclipse.m2e.core.maven2Nature</nature>

④、在项目的properties选项中，找到Deployment Assembly选项更改项目发布时的路径（看是否如下图，如果上面一切顺利，一般不用手动修改）

至此，你的项目就转化为了maven项目了。

maven所需要的jar包可以在这里进行搜索，还能看到其依赖包

Spring+SpringMVC的配置：

注：写在前面的话

一、在配置web.xml的时候寻找spring相关的配置文件：

1、没有手动指定（contextConfigLocation）路径的话，则默认去web-info下去找（spring默认找applicationContext.xml，springmvc默认找XXX-servlet.xml）。

2、如果我们把配置文件放到src下面，或者自定义包路径下的时候，可以使用classpath方式寻找。（classpath:后跟配置文件所在包的路径，可以使用通配符）

3、classpath会在当前项目去找，而classpath* 则会连所引用的包中也搜索

4、具体配置介绍请移步这里:点击打开链接

①、Web.xml

  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath*:config/spring-context.xml</param-value>
  </context-param>
  
  <servlet>
  	<servlet-name>SpringMVC</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath*:config/spring-mvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>SpringMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>

②Spring配置

	<context:property-placeholder location="classpath:jdbc.properties"/>

</beans>

③、SpringMVC配置

<?xml version="1.0" encoding="UTF-8" ?>
<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:mvc="http://www.springframework.org/schema/mvc"
    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/mvc
	    http://www.springframework.org/schema/mvc/spring-mvc.xsd">  

    <!-- 默认的注解映射的支持，自动注册DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter -->  
    <mvc:annotation-driven />
    <!-- 自动扫描的包名 -->  
    <context:component-scan base-package="com.scarecrow.elearning.uac.controller">
    	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>

    <!-- 视图解释类 -->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/jsp/"/>  
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

Mybatis的注意：

因为Mybatis的配置（包括mapper代理生成，mapper扫描等操作）交给了Spring进行管理（）

SqlSessionFactoryBean--------->用来扫描mapper.xml文件的，以及对entity生成别名，以供mapper sql文件使用。

MapperScannerConfigurer-------->用来扫描mapper接口，并给其注入sqlsession

mybatisMapper配置：

注：mybatis的mapper.xml和对应的接口可以不放在同一个包目录下，在spring对其进行扫描的时候会根据 namespace 指定的接口去生成实例代理对象。所以，namespace，在这里不止是为了sql的隔离作用，更重要的是和对应接口关联起来。

<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.scarecrow.elearning.uac.dao.UserMapper">

	<select id="getUserById" parameterType="int" resultType="User">
		select * from user where id = #{id}
	</select>
	
</mapper>

其他：因为在用mysql6.0+的开发包的时候出现了server time zone 错误，设置serverTimeZone一直乱码无法解决所以换成了5的开发包。mysql用的是5.7的，需要指定ssl为false，不过不指定也不影响开发。

jdbc.url=jdbc:mysql://localhost:3306/elearning?useUnicode=true&characterEncoding=UTF-8&serverTimeZone=GMT&useSSL=false
