SpringMVC 配置过程及详解

加入jar包

在web.xml中

添加spring监听器

1<listener>

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

3</listener>

添加spring容器（父容器）配置文件:

1<context-param>

2    <param-name>contextConfigLocation</param-name>

3    <param-value>

4        /WEB-INF/config/application-context.xml     <!--声明数据库连接参数和事务管理-->

5        /WEB-INF/config/customer-admin-manage.xml   <!--dao和service-->

6    </param-value>

7</context-param>

---

spring配置文件application-context.xml

数据库配置文件 jdbc.properties：

1jdbc.driverClassName=com.mysql.jdbc.Driver

2jdbc.url=jdbc:mysql://localhost:3306/cms?characterEncoding=UTF-8

3jdbc.username=root

4jdbc.password=123456

5...

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

1<bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

2    <property name="locations">

3        <list>

4            <value>/WEB-INF/config/jdbc.properties</value>

5        </list>

6    </property>

7</bean>

---

配置dataSource:

01<bean id="dataSource"class="com.mchange.v2.c3p0.ComboPooledDataSource">

02    <property name="driverClass"value="${jdbc.driverClassName}"/>

03    <property name="jdbcUrl"value="${jdbc.url}" />

04    <property name="user"value="${jdbc.username}" />

05    <property name="password"value="${jdbc.password}" />

06    <property name="autoCommitOnClose"value="true"/>

07    <property name="checkoutTimeout"value="${cpool.checkoutTimeout}"/>

08    <property name="initialPoolSize"value="${cpool.minPoolSize}"/>

09    <property name="minPoolSize"value="${cpool.minPoolSize}"/>

10    <property name="maxPoolSize"value="${cpool.maxPoolSize}"/>

11    <property name="maxIdleTime"value="${cpool.maxIdleTime}"/>

12    <property name="acquireIncrement"value="${cpool.acquireIncrement}"/>

13    <property name="maxIdleTimeExcessConnections"value="${cpool.maxIdleTimeExcessConnections}"/>

14</bean>

配置sessionFactory:

01<bean id="sessionFactory"class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

02    <property name="dataSource"ref="dataSource"/> 

03    <property name="mappingLocations">

04        <list>

05            <value>classpath*:/com/cms/customer/entity/hbm/*.hbm.xml</value>

06        </list>

07    </property>

08    <property name="hibernateProperties">

09        <value>

10        hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

11        hibernate.show_sql=false

12        hibernate.format_sql=false

13        hibernate.query.substitutions=true1, false0

14        hibernate.jdbc.batch_size=20

15        hibernate.cache.use_query_cache=true

16        </value>

17    </property>

18    <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）-->

19        <ref local="treeInterceptor"/>

20    </property>

21    <property name="cacheProvider">< !-- 为WEB应用提供缓存。 -->

22        <ref local="cacheProvider"/>

23    </property>

24    <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"/> -->

25        <ref bean="lobHandler"/>

26    </property>

27</bean>

基于全注解的事务声明管理

1<bean id="transactionManager"class="org.springframework.orm.hibernate3.HibernateTransactionManager">

2    <property name="sessionFactory"ref="sessionFactory" />

3</bean>

4<context:annotation-config/>

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

对于context:annotation-config

1他的作用是隐式地向 Spring 容器注册  

2AutowiredAnnotationBeanPostProcessor（想使用Autowired注解）、CommonAnnotationBeanPostProcessor、PersistenceAnnotationBeanPostProcessor、RequiredAnnotationBeanPostProcessor这4 个BeanPostProcessor。

3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

1<servlet>

2    <servlet-name>admin</servlet-name>

3    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

4    <init-param>

5        <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    -->

6        <param-value>/WEB-INF/config/admin.xml</param-value>

7    </init-param>

8    <load-on-startup>1</load-on-startup>

9</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

1<servlet>

2    <servlet-name>front</servlet-name>

3    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

4    <init-param>

5        <param-name>contextConfigLocation</param-name>

6        <param-value>/WEB-INF/config/front.xml</param-value>

7    </init-param>

8    <load-on-startup>2</load-on-startup>

9</servlet>

对于admin.xml

001<value>/WEB-INF/languages/core_admin/messages</value>

002<bean id="messageSource"class="org.springframework.context.support.ReloadableResourceBundleMessageSource">

003    <property name="cacheSeconds"value="-1"/>

004    <property name="basenames">

005        <list>

006            <value>/WEB-INF/languages/core_admin/messages</value>

007        </list>

008    </property>

009</bean>

110<!--见89行-->

111<context:annotation-config/>

112 

113<!--action注入配置文件-->

114<importresource="admin-action.xml"/>

对于：admin-action.xml

1<bean id="customerAct"class="com.customer.action.CustomerAct"/>

2<bean id="basedataAct"class="com.customer.action.BasedataAct"/>

3<bean id="employeeAct"class="com.customer.action.EmployeeAct"/>

4<bean id="projectAct"class="com.customer.action.ProjectAct"/>

5<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
