SSM框架配置文件详解
在SSM项目当中，所需要的配置文件总共有以下几个
1.web.xml
2.applicationContext.xml
3.springmvc.xml
下面将会依次详细介绍三个配置文件的配置方法以及配置的含义
1.web.xml
web.xml是ssm项目当中最重要的一个配置文件，当服务启动时会首先加载web.xml这个文件，里面包括了对前端控制器、乱码等的配置
下面贴上代码，代码当中有详细的注释解释每个配置的意思
<?xml version="1.0" encoding="UTF-8"?>
<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_4_0.xsd"
version="4.0">
<!--全局范围内参数初始化-->
<context-param>
<param-name>contextConfigLocation</param-name> <!--参数名称-->
<param-value>classpath:applicationContext.xml</param-value> <!--参数取值-->
</context-param>
<context-param>
<param-name>AREACODE</param-name>
<param-value>410800000000</param-value>
</context-param>
<!--spring的监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--springMVC的配置-->
<!--前端控制器-->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 此处不配置 默认找 /WEB-INF/[servlet-name]-servlet.xml -->
<param-value>classpath:springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<!--
1:*.do *.action 拦截以.do结尾的请求 (不拦截 jsp png jpg .js .css)
2:/ 拦截所有请求 (不拦截.jsp) 建议使用此种 方式 （拦截 .js.css .png) (放行静态资源)
3:/* 拦截所有请求（包括.jsp) 此种方式 不建议使用
-->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!--<servlet>
<servlet-name>imageServlet</servlet-name>

</servlet>
<servlet-mapping>
<servlet-name>imageServlet</servlet-name>
<url-pattern>/servlet/imageServlet</url-pattern>
</servlet-mapping>-->
<!--如果某个会话在一定时间内未被访问，则服务器可以扔掉来节约内存 单位为分钟-->
<session-config>
<session-timeout>60</session-timeout>
</session-config>
<servlet>
<servlet-name>services</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>services</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
<!-- 静态资源文件的引入 -->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>

<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.png</url-pattern>
</servlet-mapping>
<!--过滤器-->
<filter>
<description>字符集过滤器</description>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>

</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!--直接输入项目名进入时返回的页面-->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
2.applicationContext.xml
applicationContext.xml的作用是为了给spring进行配置
<?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"
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-4.0.xsd">
<context:annotation-config />
<!--自动扫描，将标注spring注解的类自动转化bean-->
<context:component-scan base-package="com.service" />
<!--配置数据库-->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value></value>
</property>
<property name="url">
<value>
</value>
</property>
<property name="username">
<value></value>
</property>
<property name="password">
<value></value>
</property>
</bean>
<!--配置sessionfactory-->
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="typeAliasesPackage" value="com.bean" />
<!--绑定数据源-->
<property name="dataSource" ref="dataSource" />
<!--自动扫描dao.xml文件-->
<property name="mapperLocations" value="classpath:com/mapper/*.xml" />
</bean>
<!--装配dao接口-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mapper" /> <!-- DAO接口所在包名，Spring会自动查找其下的类dao.class -->
</bean>
<!-- spring扫描service层@Service Controller交给springmvc管理 -->
<context:component-scan base-package="com">
<context:exclude-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
</beans>
3.springmvc.xml
springmvc.xml是为了配置springMVC
<?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-4.0.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<context:annotation-config />
<!-- springmvc扫包 @Controller, @Service ... -->
<!-- use-default-filters="false" 加上这个为了让springmvc扫完controller层就停止扫描 -->
<context:component-scan base-package="com.controller"
use-default-filters="false">
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!-- 注册转化器 -->
<mvc:annotation-driven />
<!-- 处理静态资源的 -->
<mvc:default-servlet-handler />
<!-- 视图解析器 -->
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前缀和后缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!--<mvc:interceptors>
<!– 登录权限拦截器 –>
<mvc:interceptor>
<mvc:mapping path="/**" />
<mvc:exclude-mapping path="/welcomeController/*"/>
<mvc:exclude-mapping path="/loginController/login.do"/>
<mvc:exclude-mapping path="/loginController/check.do"/>
<mvc:exclude-mapping path="/loginController/exit.do"/>
<mvc:exclude-mapping path="/registController/*"/>
<bean class="com.interceptor.LoginInterceptor">
</bean>
</mvc:interceptor>
</mvc:interceptors>-->
</beans>
据本人亲自整合，在jar包导入完全的时候，这些配置文件可直接使用（数据库连接参数被删除）
