一、关于web.xml配置
这个没啥好说的,web启动需要加载的文件都扔这里。
<?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" id="WebApp_ID" version="2.5"> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> </welcome-file-list> <!-- Spring MVC配置 --> <!-- ====================================== --> <servlet> <servlet-name>springMVC</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <!-- 可以自定义servlet.xml配置文件的位置和名称,默认为WEB-INF目录下,名称为[<servlet-name>]-servlet.xml,如springMVC-servlet.xml--> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/springMVC-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- Spring配置 --> <!-- ====================================== --> <listener> <listenerclass> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <!-- 指定Spring Bean以及数据源datasource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> <!-- ====================================== --> <!--加载其它属性文件--> <context-param> <param-name>config.file</param-name> <param-value>/config.properties</param-value> </context-param> <!--配置字符编码过滤器--> <filter> <filter-name>encoding-filter</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> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>encoding-filter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
二、关于springMVC-servlet.xml配置
springMVC-servlet这个名字是因为上面web.xml中<servlet-name>标签配的值为springMVC(<servlet-name>springMVC</servlet-name>),再加上“-servlet”后缀而形成的springMVC-servlet.xml文件名,如果改为spring,对应的文件名则为spring-servlet.xml。
<?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:p="http://www.springframework.org/schema/p" 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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!-- 自动扫描该包,使SpringMVC认为包下用了@controller注解的类是控制器--> <context:component-scan base-package="com" /> <!--mvc:message-converters消息转换器,它主要处理的是response返回的值,比如默认编码,比如支持Fastjson,当然你可以可以加入对其他返回类型的支持,比如gson,protobuf等等--> <mvc:annotation-driven> <mvc:message-converters register-defaults="true"> <!-- @ResponseBody乱码问题,将StringHttpMessageConverter的默认编码设为UTF-8 --> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <constructor-arg value="UTF-8" /> </bean> <!-- 配置Fastjson支持 --> <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"> <property name="charset" value="UTF-8" /> <property name="supportedMediaTypes"> <list> <value>application/json</value> <value>text/html;charset=UTF-8</value> </list> </property> <property name="features"> <list> <value>WriteMapNullValue</value> <value>QuoteFieldNames</value> <value>WriteDateUseDateFormat</value> <value>WriteEnumUsingToString</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> <!--对静态资源不拦截的处理--> <mvc:resources mapping="/static/**" location="classpath:/resources/static/**" /> <!--JSP视图解析器--> <bean id="viewResolverJsp" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"/> <property name="suffix" value=".jsp"/> <property name="viewClass" value="org.springframework.web.servlet.view.InternalResourceView"/> <property name="order" value="1"/> </bean> <!-- 配置freeMarker视图解析器 --> <bean id="viewResolverFtl" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/> <property name="contentType" value="text/html; charset=UTF-8"/> <property name="exposeRequestAttributes" value="true" /> <property name="exposeSessionAttributes" value="true" /> <property name="exposeSpringMacroHelpers" value="true" /> <property name="requestContextAttribute" value="request" /> <property name="cache" value="true" /> <property name="suffix" value=".ftl" /> <property name="order" value="0"/> </bean> <!-- 配置freeMarker的模板路径 --> <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/> <property name="freemarkerVariables"> <map> <entry key="xml_escape" value-ref="fmXmlEscape" /> </map> </property> <property name="defaultEncoding" value="UTF-8"/> <property name="freemarkerSettings"> <props> <prop key="template_update_delay">3600</prop> <prop key="locale">zh_CN</prop> <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop> <prop key="date_format">yyyy-MM-dd</prop> <prop key="number_format">#.##</prop> </props> </property> </bean> <bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/> <!-- 配置文件上传解析器,如果没有使用文件上传可以不用配置,当然如果不配,那么配置文件中也不必引入上传组件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> <!--统一处理异常的解析器SimpleMappingExceptionResolver--> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="warnLogCategory" value="warn" /> <property name="defaultStatusCode" value="500"/> <property name="defaultErrorView" value="/error/500"/> <property name="exceptionMappings"> <props> <prop key="java.lang.Exception">/error/500</prop> </props> </property> <property name="statusCodes"> <props> <prop key="/error/404">404</prop> <prop key="/error/404">400</prop> <prop key="/error/500">500</prop> </props> </property> </bean> <!--springmvc拦截器mvc:interceptors--> <mvc:interceptors> <mvc:interceptor> <mvc:mapping path="/**"/> <mvc:exclude-mapping path="/static/**" /> <bean class="com.xxx.interceptor.LoginRequiredInterceptor" /> </mvc:interceptor> </mvc:interceptors> </beans>
二、关于applicationContext.xml配置
spring的核心配置文件,也需要在web.xml加载。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <!--加载属性数据库文件--> <context:property-placeholder location="classpath:resource/db.properties" /> <!--C3P0连接池:使用:com.mchange.v2.c3p0.ComboPooledDataSource进行配置--> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <!-- 【必须】 数据库驱动--> <property name="driverClassName" value="${jdbc.driver}" /> <!-- 【必须】 数据库连接地址 --> <property name="url" value="${jdbc.url}" /> <!-- 【必须】 数据库用户名 --> <property name="username" value="${jdbc.username}" /> <!-- 【必须】 数据库密码 --> <property name="password" value="${jdbc.password}" /> <!-- 可选 启动时创建的连接数 --> <property name="initialSize" value="5"/> <!-- 可选 同时可从池中分配的最多连接数,0无限制 --> <property name="maxActive" value="10"/> <!-- 可选 池中不会被释放的最多空闲连接数 0无限制 --> <property name="maxIdle" value=""/> <!-- 可选 同时能从语句池中分配的预处理语句最大值,0无限制 --> <property name="maxOpenPreparedStatement" value="100"/> <!-- 可选 抛异常前池等待连接回收最大时间(当无可用连接),-1无限等待 --> <property name="maxWait" value="1000"/> <!-- 可选 连接在池中保持空闲而不被回收的最大时间 --> <property name="minEvictableIdleTimeMillis" value="2000"/> <!-- 可选 不创建新连接情况下池中保持空闲的最小连接数 --> <property name="minIdle" value="2"/> <!-- 可选 布尔值,是否对预处理语句进行池管理 --> <property name="poolPreparedStatements" value="true"/> </bean> <!--和hibernate的整合--> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <!-- 与dataSource --> <property name="dataSource"> <ref bean="dataSource"/> </property> </bean> <!-- 和mybatis的整合 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 数据库连接池 --> <property name="dataSource" ref="dataSource" /> <!-- 加载mybatis的全局配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml" /> </bean> <!-- 事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 数据源 --> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 传播行为 --> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="create*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="find*" propagation="SUPPORTS" read-only="true" /> <tx:method name="select*" propagation="SUPPORTS" read-only="true" /> <tx:method name="get*" propagation="SUPPORTS" read-only="true" /> </tx:attributes> </tx:advice> <!-- 切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.store.service.*.*(..))" /> </aop:config> <!--关于配置文件中的service层的配置。 扫描包下面所有的service层。--> <context:component-scan base-package="com.xxx.service"/> </beans>
