SpringMVC 配置过程及详解

jopen 6年前

加入jar包

在web.xml中

添加spring监听器

<listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>

添加spring容器(父容器)配置文件:

<context-param>      <param-name>contextConfigLocation</param-name>      <param-value>          /WEB-INF/config/application-context.xml     <!--声明数据库连接参数和事务管理-->          /WEB-INF/config/customer-admin-manage.xml   <!--dao和service-->      </param-value>  </context-param>

spring配置文件application-context.xml

数据库配置文件 jdbc.properties:

jdbc.driverClassName=com.mysql.jdbc.Driver  jdbc.url=jdbc:mysql://localhost:3306/cms?characterEncoding=UTF-8  jdbc.username=root  jdbc.password=123456  ...

添加到spring父容器的配置文件application-context.xml中

<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">      <property name="locations">          <list>              <value>/WEB-INF/config/jdbc.properties</value>          </list>      </property>  </bean>

配置dataSource:

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">      <property name="driverClass" value="${jdbc.driverClassName}" />      <property name="jdbcUrl" value="${jdbc.url}" />      <property name="user" value="${jdbc.username}" />      <property name="password" value="${jdbc.password}" />      <property name="autoCommitOnClose" value="true"/>      <property name="checkoutTimeout" value="${cpool.checkoutTimeout}"/>      <property name="initialPoolSize" value="${cpool.minPoolSize}"/>      <property name="minPoolSize" value="${cpool.minPoolSize}"/>      <property name="maxPoolSize" value="${cpool.maxPoolSize}"/>      <property name="maxIdleTime" value="${cpool.maxIdleTime}"/>      <property name="acquireIncrement" value="${cpool.acquireIncrement}"/>      <property name="maxIdleTimeExcessConnections" value="${cpool.maxIdleTimeExcessConnections}"/>  </bean>

配置sessionFactory:

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">      <property name="dataSource" ref="dataSource"/>        <property name="mappingLocations">          <list>              <value>classpath*:/com/cms/customer/entity/hbm/*.hbm.xml</value>          </list>      </property>      <property name="hibernateProperties">          <value>          hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect          hibernate.show_sql=false          hibernate.format_sql=false          hibernate.query.substitutions=true 1, false 0          hibernate.jdbc.batch_size=20          hibernate.cache.use_query_cache=true          </value>      </property>      <property name="entityInterceptor">< !-- 配置Hibernate拦截器,自动填充数据的插入、更新时间(不知道什么意思)-->          <ref local="treeInterceptor"/>      </property>      <property name="cacheProvider">< !-- 为WEB应用提供缓存。 -->          <ref local="cacheProvider"/>      </property>      <property name="lobHandler">< !-- spring提供的操作lob字段。<bean id="lobHandler" class="org.springframework.jdbc.support.lob.DefaultLobHandler" lazy-init="true"/> -->          <ref bean="lobHandler" />      </property>  </bean>

基于全注解的事务声明管理

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">      <property name="sessionFactory" ref="sessionFactory" />  </bean>  <context:annotation-config/>  <tx:annotation-driven transaction-manager="transactionManager" />

对于context:annotation-config

他的作用是隐式地向 Spring 容器注册     AutowiredAnnotationBeanPostProcessor(想使用Autowired注解)、CommonAnnotationBeanPostProcessor、PersistenceAnnotationBeanPostProcessor、RequiredAnnotationBeanPostProcessor这 4 个BeanPostProcessor。  另外,<context:component-scan base-package=”XX.XX”/>(用于自动扫描需要注入的bean) 包含了<context:annotation-config/>的功能,在这里没有使用<context:component-scan base-package=”XX.XX”/>,则必须将bean添加到父容器的(dao,service,manager之类的)xml中

对于tx:annotation-driven ,则表示所有Transactional注解了的manager都使用这个事务管理

配置springmvc(子容器)

添加springmvc的Servlet

<servlet>      <servlet-name>admin</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>          <param-name>contextConfigLocation</param-name><!--指定注入action的配置文件,如果没有指定,则默认在web-inf下查找admin-servlet.xml    -->          <param-value>/WEB-INF/config/admin.xml</param-value>      </init-param>      <load-on-startup>1</load-on-startup>  </servlet>

每一个servlet对应一个配置文件,用于映射不同的请求路径集合

<servlet>      <servlet-name>front</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>          <param-name>contextConfigLocation</param-name>          <param-value>/WEB-INF/config/front.xml</param-value>      </init-param>      <load-on-startup>2</load-on-startup>  </servlet>

对于admin.xml

<value>/WEB-INF/languages/core_admin/messages</value>  <bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">      <property name="cacheSeconds" value="-1"/>      <property name="basenames">          <list>              <value>/WEB-INF/languages/core_admin/messages</value>          </list>      </property>  </bean>    <!--文件上传-->  <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"/>    <!--通过注解,把一个URL映射到Controller类的方法上-->  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">      <property name="webBindingInitializer"><!--重写WebBindingInitializer-->          <bean class=" com.cms.common.web.springmvc.BindingInitializer"/>      </property>  </bean>    <!--用于Spring 从外部属性文件中载入属性,并使用这些属性值替换Spring 配置文件中的占位符变量(${varible})。 -->  <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">      <property name="locations">          <list>              <value>/WEB-INF/config/firewall.properties</value>          </list>      </property>  </bean>    <!--    DefaultAnnotationHandlerMapping-映射url到被RequestMapping注解的controller或者下面的方法-->  <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">      <property name="interceptors">          <list>              <ref bean="adminContextInterceptor"/>              <ref bean="adminLocaleIntercept"/>              <ref bean="fireWallInterceptor"/>          </list>      </property>  </bean>  <!--拦截器-->  <bean id="adminContextInterceptor" class="com.cms.cms.web.AdminContextInterceptor">      <property name="auth" value="true"/>      <property name="loginUrl" value="/admin/cms/login.do"/>      <property name="returnUrl" value="/admin/cms/index.do"/>      <property name="excludeUrls">          <list>              <value>/login.do</value>              <value>/logout.do</value>          </list>      </property>  </bean>  <bean id="adminLocaleIntercept" class="com.cms.cms.web.AdminLocaleInterceptor"/>  <bean id="fireWallInterceptor" class="com.cms.cms.web.FireWallInterceptor"></bean>    <!--Cookie相关-->  <bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">      <property name="cookieName" value="clientlanguage"/>      <property name="cookieMaxAge" value="-1"/>  </bean>    <!--定义一场处理-->  <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">      <property name="exceptionMappings">          <props>              <prop key="org.springframework.web.bind.MissingServletRequestParameterException">/error/requiredParameter</prop>              <prop key="org.springframework.beans.TypeMismatchException">/error/mismatchParameter</prop>              <prop key="org.springframework.web.bind.ServletRequestBindingException">/error/bindException</prop>              <prop key="org.springframework.dao.DataIntegrityViolationException">/error/integrityViolation</prop>          </props>      </property>  </bean>  <!--freemarker配置-->  <bean id="freemarkerViewResolver" class="com.cms.common.web.springmvc.RichFreeMarkerViewResolver">      <property name="prefix" value="/cms_sys/"/>      <property name="suffix" value=".html"/>      <property name="contentType" value="text/html; charset=UTF-8"/>      <property name="exposeRequestAttributes" value="false"/>      <property name="exposeSessionAttributes" value="false"/>      <property name="exposeSpringMacroHelpers" value="true"/>  </bean>  <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">      <property name="templateLoaderPath" value="/WEB-INF"/>      <property name="freemarkerVariables">          <map>              <!--在FCK编辑器中需要用到appBase,以确定connector路径。-->              <entry key="appBase" value="/admin/cms"/>              <!--后台管理权限控制-->              <entry key="cms_perm" value-ref="cms_perm"/>              <entry key="text_cut" value-ref="text_cut"/>              <entry key="html_cut" value-ref="html_cut"/>          </map>      </property>      <property name="freemarkerSettings">          <props>              <prop key="template_update_delay">0</prop>              <prop key="defaultEncoding">UTF-8</prop>              <prop key="url_escaping_charset">UTF-8</prop>              <prop key="locale">zh_CN</prop>              <prop key="boolean_format">true,false</prop>              <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>              <prop key="date_format">yyyy-MM-dd</prop>              <prop key="time_format">HH:mm:ss</prop>              <prop key="number_format">0.######</prop>              <prop key="whitespace_stripping">true</prop>              <prop key="auto_import">/ftl/cms/index.ftl as p,/ftl/spring.ftl as s</prop>          </props>      </property>  </bean>    <!--见89行-->  <context:annotation-config/>    <!--action注入配置文件-->  <import resource="admin-action.xml"/>

对于:admin-action.xml

<bean id="customerAct" class="com.customer.action.CustomerAct"/>  <bean id="basedataAct" class="com.customer.action.BasedataAct"/>  <bean id="employeeAct" class="com.customer.action.EmployeeAct"/>  <bean id="projectAct" class="com.customer.action.ProjectAct"/>  <bean id="productAct" class="com.customer.action.ProductAct"/>

每一个action都要用Controller注解,其中使用的manager属性用Autowired注解,每一个方法都要用RequestMapping注解
每一个manager都要用Service,Transactional注解
