Spring：配置文件

首先是bean.xml，配置所有的bean，一般也叫applicationContext.xml，应用程序上下文。示例：

<?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:tx="http://www.springframework.org/schema/tx"
       xmlns:websocket="http://www.springframework.org/schema/websocket"
       xmlns:task="http://www.springframework.org/schema/task"
       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/websocket
http://www.springframework.org/schema/websocket/spring-websocket-4.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">

    <context:component-scan base-package="com.guangshan" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Repository"/>
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Component"/>
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>

    <bean id="dataSource"
          class="com.mchange.v2.c3p0.ComboPooledDataSource"
          destroy-method="close">
        <property name="driverClass" value="${c3p0.driverClass}"></property>
        <property name="jdbcUrl" value="${c3p0.url}"></property>
        <property name="user" value="${c3p0.user}"></property>
        <property name="password" value="${c3p0.password}"></property>
        <property name="acquireIncrement" value="${c3p0.acquireIncrement}"></property>
        <property name="initialPoolSize" value="${c3p0.initialPoolSize}"></property>
        <property name="maxIdleTime" value="${c3p0.maxIdleTime}"></property>
        <property name="maxPoolSize" value="${c3p0.maxPoolSize}"></property>
        <property name="minPoolSize" value="${c3p0.minPoolSize}"></property>
        <property name="acquireRetryDelay" value="1000"></property>
        <property name="acquireRetryAttempts" value="60"></property>
        <property name="breakAfterAcquireFailure" value="false"></property>
    </bean>

    <bean id="propertyConfigurer"
          class="com.guangshan.framework.core.SpringPropertiesUtil" lazy-init="false">
        <property name="locations">
            <list>
                <value>classpath:config/sys.properties</value>
            </list>
        </property>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <bean id="jdbcTxManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
    </bean>

    <tx:annotation-driven transaction-manager="jdbcTxManager"></tx:annotation-driven>

    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
         <property name="maxUploadSize" value="2097152"/>
    </bean>

　　若只用Spring做View层时，还有一个mvc-dispatcher-servlet.xml调度文件，示例

<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" xmlns:p="http://www.springframework.org/schema/p"
       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">

    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
                <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                    <property name="supportedMediaTypes">
                        <list>
                            <value>text/plain;charset=UTF-8</value>
                        </list>
                    </property>
                </bean>
                <bean class="org.springframework.http.converter.ResourceHttpMessageConverter"/>
                <bean class="org.springframework.http.converter.xml.SourceHttpMessageConverter"/>
                <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"/>
                <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"/>
            </list>
        </property>
        <property name="synchronizeOnSession" value="true"/>
    </bean>

    <mvc:annotation-driven/>

    <!-- 静态资源访问 -->

    <mvc:resources location="/assets/**" mapping="/assets/**"/>
    <mvc:resources location="/public/**" mapping="/public/**"/>
    <mvc:resources location="/aui/**" mapping="/aui/**"/>
    <mvc:resources location="/docs/**" mapping="/docs/**"/>

    <context:component-scan base-package="com.guangshan" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- freemarker-->
    <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"
          p:exposeSpringMacroHelpers="true">
        <property name="prefix" value=""/>
        <property name="suffix" value=".ftl"/>
        <property name="contentType" value="text/html; charset=UTF-8"/>
    </bean>

    <bean id="freemarkerConfig"
          class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPath" value="/WEB-INF/views/"/>
        <property name="freemarkerSettings">
            <props>
                <prop key="defaultEncoding">UTF-8</prop>
                <prop key="auto_import">common.ftl as c</prop>
                <prop key="number_format">0.##</prop>
            </props>
        </property>
    </bean>

    <!---jade -->
    <bean id="templateLoader" class="de.neuland.jade4j.spring.template.SpringTemplateLoader">
        <property name="basePath" value="/WEB-INF/view/"/>
    </bean>

    <bean id="jadeConfiguration" class="de.neuland.jade4j.JadeConfiguration">
        <property name="prettyPrint" value="false"/>
        <property name="caching" value="false"/>
        <property name="templateLoader" ref="templateLoader"/>
    </bean>

    <bean id="viewResolver" class="de.neuland.jade4j.spring.view.JadeViewResolver">
        <property name="configuration" ref="jadeConfiguration"/>
        <property name="renderExceptions" value="true"/>
    </bean>

    <!--jsp-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <mvc:interceptors>
        <bean class="com.guangshan.framework.core.MvcInterceptor"></bean>
    </mvc:interceptors>

</beans>

3、在web.xml中，可以定义上一个文件的位置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

            <param-name>encoding</param-name>

        </init-param>
    </filter>

    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!-- log4j 配置 -->

    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.util.Log4jConfigListener
        </listener-class>
    </listener>

    <!-- Spring注册容器所需要的配置 -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener

    </listener>
    <!-- 自定义启动 -->
    <listener>
        <listener-class>
            com.ruishengtech.rscc.crm.ui.SysInitListener
        </listener-class>
    </listener>

    <!-- 指定Spring Bean的配置文件所在目录。默认配置在WEB-INF目录下 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:config/applicationContext.xml
        </param-value>
    </context-param>

    <servlet>
        <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    </servlet>

    <servlet-mapping>
        <servlet-name>mvc-dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <session-config>
        <session-timeout>60</session-timeout>
    </session-config>
</web-app>
