springmvc(基础二) Springmvc 配置过程及详解

一、在pom.xml配置

添加依赖相应的jar包

二、web.xml配置

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:

<span style="font-weight: normal;"><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></span>

三、spring配置文件application-context.xml配置

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

四、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>

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.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"/>

<property name="freemarkerSettings">

<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"/>

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
