在Maven使用中，已经添加好SSM所需的各类包，接下来便需要把SSM所需的配置文件新增好，首先添加SpringMVC相关配置，分别是applicationContext.xml配置、log4j.properties配置文件和spring-mvc.xml配置文件，applicationContext.xml配置如下:

<?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:p="http://www.springframework.org/schema/p" 
	xmlns:context="http://www.springframework.org/schema/context" 
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx" 
	xmlns:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="
	http://www.springframework.org/schema/tx
	http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
	http://www.springframework.org/schema/aop
	http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.1.xsd
	http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
	http://www.springframework.org/schema/task 
	http://www.springframework.org/schema/task/spring-task-3.1.xsd " >
	
	<!-- 开启注解 -->
	<context:annotation-config />
	
	<!-- 开启定时任务 -->
	<task:annotation-driven/>
	
	<!-- 自动扫描(service)，(mapper) -->
	<context:component-scan base-package="com.gx.mapper,com.gx.service,com.gx.job">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Service"></context:include-filter>
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"></context:include-filter>
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Component"></context:include-filter>
	</context:component-scan>
</beans>

log4j.properties配置如下:

#\u914d\u7f6e\u6839 Logger
log4j.rootLogger = INFO , appender1

#\u914d\u7f6e\u65e5\u5fd7\u4fe1\u606f\u8f93\u51fa\u76ee\u7684\u5730\uff08appender\uff09
#appender1 \u8f93\u51fa\u5230\u63a7\u5236\u53f0
log4j.appender.appender1 = org.apache.log4j.ConsoleAppender
log4j.appender.appender1.Threshold=INFO
log4j.appender.appender1.Target=System.err
log4j.appender.appender1.layout=org.apache.log4j.TTCCLayout

spring-mvc.xml配置如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:p="http://www.springframework.org/schema/p" 
	xmlns:context="http://www.springframework.org/schema/context" 
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="
	http://www.springframework.org/schema/beans
	http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
	http://www.springframework.org/schema/context
	http://www.springframework.org/schema/context/spring-context-3.1.xsd
	http://www.springframework.org/schema/aop   
	http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
	http://www.springframework.org/schema/mvc
	http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd ">
	
	<!-- 日期转换 必须放在<mvc:annotation‐driven />前面 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
</bean>
	<!-- 注解方式 -->
	<mvc:annotation-driven></mvc:annotation-driven>
	<!-- 自动扫描且只扫描@Controller Component -->
	<context:component-scan base-package="com.gx.web,com.gx.aop">
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
		<context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
	</context:component-scan>
	
	<aop:aspectj-autoproxy proxy-target-class="true" />
	
	<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
	<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/jsp"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
	
	<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" >
		<property name="defaultEncoding" value="utf-8"/>
		<!-- 指定所上传文件的总大小不能超过2MB。注意maxUploadSize属性的限制不是针对单个文件，而是所有文件的容量之和 -->
		<property name="maxUploadSize" value="2097152" />
		<property name="maxInMemorySize" value="40960" />
	</bean>
</beans>

然后是mybaits相关配置，分别是jdbc.properties配置文件、mybatis-config.xml配置文件和spring-mybatis.xml配置文件，jdbc.properties配置文件如下:

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/bookmanagement?useUnicode=true&amp;characterEncoding=utf-8
username=root
password=root
validationQuery=SELECT 1

mybatis-config.xml配置文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<settings>
		<!-- 打印查询语句 -->
		<setting name="logImpl" value="STDOUT_LOGGING" />
	</settings>
</configuration>

spring-mybatis.xml配置文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

以上配置文件都应添加到src.main.resources下，如下图:
