在做一个web项目的时候接触到了ssm框架的整合，因此在这里将自己的整合过程及文件配置记录一下，以备以后自己查看。其中有些功能配置未在配置文件中注明，需要的时候再加入即可。

一、项目框架


               



二、maven 依赖

<properties>
  	<!-- spring版本号 -->
  	<spring.version>4.1.7.RELEASE</spring.version>

  </properties>
  
  <dependencies>
    <dependency>

	    <artifactId>junit</artifactId>
	    <version>4.12</version>
	    <scope>test</scope>
    </dependency>
    
    <!-- 补全项目依赖 -->
    <!-- 1:	引入日志实现包 
		    java日志：slf4j，log4j，logback，common-logging

        <artifactId>poi-scratchpad</artifactId>
        <version>3.8</version>
    </dependency>
    
  </dependencies>


三、DAO层整合（spring+mybatis）


3.1 mybatis全局文件配置：mybatis-config.xml


<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://www.mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<!-- 配置全局属性 -->
	<settings>
		<!-- 使用jdbc的getGeneratedKEYS 获取数据库自增主键 -->
		<setting name="useGeneratedKeys" value="true"/>
		<!-- 使用列别名替换列名 默认：true -->
		<setting name="useColumnLabel" value="true"/>
		<!-- 开启驼峰命名转换 -->
		<setting name="mapUnderscoreToCamelCase" value="true"/>
		<!--日志输出sql语句-->
		<setting name="logImpl" value="STDOUT_LOGGING"/>
	</settings>
	
</configuration>

3.2 spring—mybatis.xml配置文件


<?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"
	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">

	<!-- 配置整合mybatis过程 -->
	<!-- 1: 配置数据库相关参数 -->
	<context:property-placeholder location="classpath:jdbc.properties"/>
	<!-- 2: 配置数据库连接池 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<!-- 配置连接池属性 -->
		<property name="driverClass" value="${jdbc.driverClass}"/>
		<property name="jdbcUrl" value="${jdbc.url}"/>
		<property name="user" value="${jdbc.username}"/>
		<property name="password" value="${jdbc.password}"/>
		<!-- c3p0连接池的私有属性-->
		<property name="maxPoolSize" value="30"/>
		<property name="minPoolSize" value="10"/>
		<!-- 关闭连接后不自动commit -->
		<property name="autoCommitOnClose" value="false"/>
		<!-- 获取连接超时时间 -->
		<property name="checkoutTimeout" value="1000"/>
		<!-- 当获取连接失败重试的次数 -->
		<property name="acquireRetryAttempts" value="2"/>
	</bean>
	<!-- 3: 配置sqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 注入数据库连接池 -->
		<property name="dataSource" ref="dataSource"/>
		<!-- 配置mybatis全局配置文件：mybatis-config.xml -->
		<property name="configLocation" value="classpath:mybatis-config.xml"/>
		<!-- 扫描entity包 使用别名 -->
		<property name="typeAliasesPackage" value="com.tradingplatform.entity"/>
		<!-- 扫描sql配置文件：mapper需要的xml文件 -->
		<property name="mapperLocations" value="classpath:mapper/*.xml"/>
	</bean>
	<!-- 4: 配置扫描DAO接口包，动态实现Dao接口，注入到spring容器中 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!--注入sqlSessionFactory-->
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
		<property name="basePackage" value="com.tradingplatform.dao"/>
	</bean>
</beans>

3.4 jdbc.properties配置文件


##message about database
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/tradingplatform?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=1234


3.4 log4j.properties配置文件


### Global logging configuration
log4j.rootLogger=INFO,Console

### Uncomment for MyBatis logging
#log4j.logger.org.apache.ibatis=ERROR

#log4j.logger.org.apache.ibatis.session.AutoMappingUnknownColumnBehavior=WARN, lastEventSavedAppender

### Console output...
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
#%5p [%t] - %m%n
#%d [%t] %-5p [%c] - %m%n
#log4j.appender.lastEventSavedAppender=org.apache.ibatis.session.AutoMappingUnknownColumnBehaviorTest$LastEventSavedAppender




<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration>
    <appender name="console" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern"
                   value="[%d{dd HH:mm:ss,SSS\} %-5p] [%t] %c{2\} - %m%n"/>
        </layout>
        <!--过滤器设置输出的级别-->
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="levelMin" value="debug"/>
            <param name="levelMax" value="error"/>
            <param name="AcceptOnMatch" value="true"/>
        </filter>
    </appender>
    <appender name="dailyRollingFileAppender" class="org.apache.log4j.DailyRollingFileAppender">
        <param name="File" value="/data/data.log"/>
        <param name="DatePattern" value="'.'yyyy-MM-dd'.log'"/>
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="[%d{yyyy-MM-dd HH:mm:ss\} %-5p] [%t] {%c:%L}-%m%n"></param>
        </layout>
    </appender>
    <!-- 根logger的设置-->
    <root>
        <priority value="debug"/>
        <appender-ref ref="console"/>
        <appender-ref ref="dailyRollingFileAppender"/>
    </root>
</log4j:configuration>





日志实现在类中的注入：


private final Logger log=LoggerFactory.getLogger(this.getClass());


四、service层整合


spring—service.xml配置文件


<?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" 
	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:component-scan base-package="com.tradingplatform.service"/>
</beans>


五、web层整合（spring+springMVC）


5.1 spring-mvc.xml配置文件

<?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">
	<!-- 开启注解 -->
	<mvc:annotation-driven/>

	<!-- jsp的显示 -->	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
 		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
 		<property name="prefix" value="/WEB-INF/jsps/"/>
 		<property name="suffix" value=".jsp"/>
 	</bean>
 	<!-- 包扫描 -->
 	<context:component-scan base-package="com.tradingplatform.controller"/>
 	<!-- 静态资源处理， css， js， imgs -->
 	<mvc:resources mapping="/resources/**" location="/resources/" />
 	<!--200*1024*1024即200M resolveLazily属性启用是为了推迟文件解析，以便捕获文件大小异常 -->
	<bean id="multipartResolver"
		class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
		<property name="maxUploadSize" value="209715200" />
		<property name="defaultEncoding" value="UTF-8" />
		<property name="resolveLazily" value="true" />
	</bean>
	<!-- 注册拦截器 -->  
	<mvc:interceptors>  
	   <!-- 管理员登陆拦截器 -->  
	   <mvc:interceptor>  
	       <mvc:mapping path="/manager/*"/>  
	       <bean class="com.tradingplatform.interceptor.ManagerLoginInterceptor"></bean>  
	   </mvc:interceptor>
	   <!-- 用户操作的拦截器 -->
	   <mvc:interceptor>  
	       <mvc:mapping path="/user/*"/>  
	       <bean class="com.tradingplatform.interceptor.UserdealInterceptor"></bean>  
	   </mvc:interceptor> 
	</mvc:interceptors>  
	
</beans>


5.2 web.xml文件配置


<?xml version="1.0" encoding="UTF-8"?>
<web-app 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
	  http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
	  id="WebApp_ID"
	  version="3.1">
	<display-name>Archetype Created Web Application</display-name>
	
	<!-- 配置DisPatcherServlet -->
	<servlet>
		<servlet-name>tradingplatform-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>tradingplatform-dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>


六、Junit测试整合结果
测试文件样例如下： 


//包的加载根据相应的类文件加载

import javax.annotation.Resource;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
//service层测试
@ContextConfiguration(locations=
			{"classpath:spring/spring-mybatis.xml",
			"classpath:spring/spring-service.xml"})

//dao层测试加载的配置文件@ContextConfiguration("classpath:spring/spring-mybatis.xml")
public class CommonActionServiceImplTest {

	@Resource
	CommonActionServiceImpl commonActionServiceImpl;	//测试的类，可变更
	
	@Test
	public void testGetLandDetails() {
		//测试函数
	}
}







整合过程写的有点简略，欢迎大家指点，转载请注明出处。
