关于SSM配置文件的设置，必看！！！

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>
    <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>

        <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>

    <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>
        &lt;!&ndash; 登录权限拦截器 &ndash;&gt;
        <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>

小提示

关于配置文件这个东西，在初学各种框架的时候非常让人头疼，一不小心配置错误，项目就运行不了。所以不如直接从网上找个小项目的源码把代码删除，直接用别人的配置来做练习，在框架能熟练运用之后再慢慢学习配置文件的问题。
