## 1.创建maven工程导入坐标 ##

1.      Spring： spring-context 5.0.2 （spring容器）     spring-tx 5.0.2（spring事务）     spring-jdbc 5.0.2（springJDBC）                                                     spring-test   5.0.2（spring单元测试）   spring-webmvc 5.0.2（springMVC） 
2.      Mybatis：mybatis     3.4.5  （mybatis核心）      mybatis-spring   1.3.1   （mybatis与Spring整合所需）
3.     切面：  aspectjweaver    1.8.7    （Spring依赖的AOP框架）   
4.     数据库：mysql-connector-java 5.1.6    （MySql数据库驱动）
5.     单元测试： junit    4.12    （单元测试）
6.     ServletAPI：  jsp-api    2.0   （jsp页面使用request等对像）      servlet-api    2.5 （java文件使用request等对象）                                //注意:这两个jar包的 scope 属性需要设置为 provided
7.    页面表达式：JSTL   1.2 （jstl标签库 ）       standard    1.1.2   （jstl标签库依赖jar包）

## 2.编写配置文件 ##

1.    数据库配置文件（db.properties）
    
        jdbc.driver = com.mysql.jdbc.Driver
        jdbc.url = jdbc:mysql://127.0.0.1:3306/springdb?characterEncoding=UTF-8
        jdbc.username = root
        jdbc.password = root
    
     
2.    编写mybatis配置文件(sqlSessionConfig.xml)
    
        <configuration>
        			
        		<settings>
        			<setting name="logImpl" value="STDOUT_LOGGING"/>
        		</settings>
        		
        		<plugins>
        	        <plugin interceptor="com.github.pagehelper.PageInterceptor">
        	            
        	            <property name="reasonable" value="true"/>
        	        </plugin>
        	    </plugins>
        	</configuration>
    
     
3.    编写Spring配置文件(applicationContext.xml)
    
        <?xml version="1.0" encoding="UTF-8"?>
        <beans xmlns="http://www.springframework.org/schema/beans"
        	xmlns:context="http://www.springframework.org/schema/context" 
        	xmlns:tx="http://www.springframework.org/schema/tx"
        	xmlns:aop="http://www.springframework.org/schema/aop" 
        	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        	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
        		http://www.springframework.org/schema/aop
        		http://www.springframework.org/schema/aop/spring-aop.xsd">
        		
        			
        	<context:property-placeholder location="classpath:db.properties"/>
        		
        			
        	<context:component-scan base-package="com.zzz">
        		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
        	</context:component-scan>	
        		
        	
        	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        		
        		<property name="driverClassName" value="${jdbc.driver}" />
        		<property name="url" value="${jdbc.url}" />
        		<property name="username" value="${jdbc.username}" />
        		<property name="password" value="${jdbc.password}" />
        	</bean>
        	
        	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        		
        		<property name="dataSource" ref="dataSource" />
        	</bean>
        
        	
        	<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
        
        	
        	<bean class="org.mybatis.spring.SqlSessionFactoryBean">
        		<property name="configLocation" value="classpath:sqlMapConfig.xml" />
        		<property name="dataSource" ref="dataSource" />
        	</bean>
        
        	
        	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        		<property name="basePackage" value="com.zzz.dao" />
        	</bean>
        
        
        </beans>
    
     
4.  编写SpringMVC的配置文件(spring-mvc.xml)
    
        <?xml version="1.0" encoding="UTF-8"?>
        		<beans xmlns="http://www.springframework.org/schema/beans"
        			xmlns:context="http://www.springframework.org/schema/context"
        			xmlns:mvc="http://www.springframework.org/schema/mvc" 
        			xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        			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">
        
        			1.扫描view层注解配置所在包
        			
        				<context:component-scan base-package="com.zzz">
        					1.1配置只包含web的后端处理器
        					<context:include-filter type="annotation" 
                            expression="org.springframework.stereotype.Controller"/>
        				</context:component-scan>
        			
        			2.加载SpringMVC的三大组件
        			
        				<mvc:annotation-driven />
        			
        			3.配置视图解析器
        			
        				<bean 
                       class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        					<property name="prefix" value="/WEB-INF/pages/" />
        					<property name="suffix" value=".jsp" />
        				</bean>
        			
        			4.配置静态资源不拦截
        			
        				<mvc:resources location="/js/" mapping="/js/**" />
        				<mvc:resources location="/css/" mapping="/css/**" />
        				<mvc:resources location="/image/" mapping="/image/**" />
        
        		</beans>

## 3.修改web.xml配置(WEB-INF目录下的web.xml) ##

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xmlns="http://java.sun.com/xml/ns/javaee" 
    	xsi:schemaLocation="
    		http://java.sun.com/xml/ns/javaee 
    		http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
    		version="2.5">
      <display-name>msgboard</display-name>
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      
    	  
    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath:appliactionContext.xml</param-value>
    	</context-param>
    	
    	
    	<listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
    	
    	
    	<filter>
    		<filter-name>characterEncodingFilter</filter-name>
    		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    		
    		<init-param>
    			<param-name>encoding</param-name>
    			<param-value>UTF-8</param-value>
    		</init-param>
    	</filter>
      	<filter-mapping>
      		<filter-name>characterEncodingFilter</filter-name>
      		<url-pattern>/*</url-pattern>
      	</filter-mapping>
      	
      	
      	<servlet>
      		<servlet-name>dispatcherServlet</servlet-name>
      		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      		
      		<init-param>
      			<param-name>contextConfigLocation</param-name>
      			<param-value>classpath:spring-mvc.xml</param-value>
      		</init-param>
      		
      		<load-on-startup>1</load-on-startup>
      	</servlet>
      	<servlet-mapping>
      		<servlet-name>dispatcherServlet</servlet-name>
      		<url-pattern>/</url-pattern>
      	</servlet-mapping>
      	
    </web-app>
