spring mvc 的搭建

首先配置web.xml，配置Spring的监听器，用于初始化ApplicationContext对象：

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <!-- 配置Spring的监听器，用于初始化ApplicationContext对象 -->    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>  </web-app>

然后配置ApplicationContext对象的参数：

  <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:applicationContext*.xml</param-value>    </context-param>  

然后添加spring mvc servlet :

 <servlet>  <description>spring mvc servlet</description>  <servlet-name>springMvc</servlet-name>  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  <init-param>   <description>spring mvc 配置文件</description>   <param-name>contextConfigLocation</param-name>   <param-value>classpath:spring-mvc.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping>  <servlet-name>springMvc</servlet-name>  <url-pattern>*.do</url-pattern> </servlet-mapping>

数据库连接方式：proxool

 

<!-- proxool --> <servlet>  <servlet-name>ServletConfigurator</servlet-name>  <servlet-class>   org.logicalcobwebs.proxool.configuration.ServletConfigurator  </servlet-class>  <init-param>   <param-name>xmlFile</param-name>   <param-value>WEB-INF/proxool.xml</param-value>  </init-param>  <load-on-startup>1</load-on-startup> </servlet> <!-- proxool监控 --> <servlet>  <servlet-name>Admin</servlet-name>  <servlet-class>   org.logicalcobwebs.proxool.admin.servlet.AdminServlet  </servlet-class> </servlet>

监控url:

 <servlet-mapping>  <servlet-name>Admin</servlet-name>  <url-pattern>/admin</url-pattern> </servlet-mapping>

配置applicationContext.xml文件(在src目录下)：

<?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:aop="http://www.springframework.org/schema/aop"         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/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd                 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">    </beans>

首先，自动扫描与装配bean：

 

     <!-- 自动扫描与装配bean -->          <context:component-scan base-package="com.xxx.jcy.entity"/>    <context:component-scan base-package="com.xxx.jcy.daoI"/>    <context:component-scan base-package="com.xxx.jcy.daoImpl"/>    <context:component-scan base-package="com.xxx.jcy.serviceI"/>    <context:component-scan base-package="com.xxx.jcy.serviceImpl"/>      <!-- Spring 获取配置文件中定义的bean -->    <context:annotation-config/>    <!-- dbcp配置 -->        <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">              <property name="driverClassName">                <value>org.logicalcobwebs.proxool.ProxoolDriver</value>            </property>            <property name="url">                <value>proxool.1EEAFDADAA5014E938548EF816B3C6E1</value>            </property>        </bean>        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">                <property name="dataSource">                <ref local="dataSource" />            </property>            <property name="hibernateProperties">                <props>                    <!--配置Hibernate的方言-->                    <prop key="hibernate.dialect">                     org.hibernate.dialect.OracleDialect                    </prop>                                    <prop key="hibernate.hbm2ddl.auto">update</prop>                                       <!--格式化输出sql语句-->                    <prop key="hibernate.show_sql">true</prop>                    <prop key="hibernate.format_sql">true</prop>                      <prop key="hibernate.use_sql_comments">false</prop>                  <prop key="hibernate.cache.use_second_level_cache">false</prop>                <!--                    <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>             -->            </props>            </property>             <!-- 注解方式配置 -->  <property name="packagesToScan">   <list>    <value>com.xxx.jcy.entity</value>   </list>  </property>    </bean>         <!-- JDBC配置 --> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">  <property name="dataSource">  <ref bean="dataSource"/>  </property> </bean>      <!--自动扫描实体 -->     <bean name="transactionManager"  class="org.springframework.orm.hibernate4.HibernateTransactionManager">  <property name="sessionFactory" ref="sessionFactory"></property> </bean>   <!-- 配置事务 --> <tx:annotation-driven transaction-manager="transactionManager" />

接下来，配置spring-mvc.xml(在src目录下)：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:mvc="http://www.springframework.org/schema/mvc" 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"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/mvchttp://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd ">  <context:annotation-config /> <!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 --> <context:component-scan base-package="com.xxx.jcy.action"></context:component-scan>  <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />  <!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->           <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"              p:prefix="/WEB-INF/view/" p:suffix=".jsp" />      <bean id="multipartResolver"              class="org.springframework.web.multipart.commons.CommonsMultipartResolver"              p:defaultEncoding="utf-8" />   </beans>

另外，proxool.xml(在WEB-INF目录下) 文件内容如下：

<?xml version='1.0' encoding='iso-8859-1'?><something-else-entirely> <proxool>  <alias>1EEAFDADAA5014E938548EF816B3C6E1</alias>  <driver-url>jdbc:oracle:thin:@192.168.16.46:1521:orcl</driver-url>  <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>  <driver-properties>   <property name="user" value="jcy1"/>   <property name="password" value="jcy1"/>  </driver-properties>  <house-keeping-sleep-time>90000</house-keeping-sleep-time>  <simultaneous-build-throttle>20</simultaneous-build-throttle>  <prototype-count>5</prototype-count>  <maximum-connection-count>200</maximum-connection-count>  <minimum-connection-count>10</minimum-connection-count> </proxool> <proxool>  <alias>proxool</alias>  <driver-url>jdbc:oracle:thin:@192.168.16.46:1521:orcl</driver-url>  <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>  <driver-properties>   <property name="user" value="JCY"/>   <property name="password" value="JCY"/>  </driver-properties>  <house-keeping-sleep-time>90000</house-keeping-sleep-time>  <simultaneous-build-throttle>20</simultaneous-build-throttle>  <prototype-count>5</prototype-count>  <maximum-connection-count>200</maximum-connection-count>  <minimum-connection-count>10</minimum-connection-count> </proxool></something-else-entirely>

接下来是java MVC层的代码示例：

DAO层：

首先定义接口：

public interface CommonDaoI {}

实现类：

@Repository("commonDao")public class CommonDaoImpl implements CommonDaoI {@Autowired private JdbcTemplate jdbcTemplate;@Autowiredprivate SessionFactory sessionFactory;//TODO 以下可自由于添加操作数据库的方法}

Service层：

接口：

public interface CommonServiceI {}

实现类：

@Service("commonServiceImpl")@Transactionalpublic class CommonServiceImpl implements CommonServiceI {    @Autowired     private CommonDaoI commonDao ;        //.......方法}

控制层：

@Controller@RequestMapping("/commonAction.do")public class CommonAction {  @Autowired private CommonServiceI commonService ;//检查验证码是否正确，正确返回"1"@RequestMapping(params="checkHtmlCode") public void checkHtmlCode(HttpServletRequest request,HttpServletResponse response){  String htmlCode = request.getSession().getAttribute("htmlCode").toString();  String checkCode = request.getParameter("checkCode");  if(checkCode!=null && checkCode.equalsIgnoreCase(htmlCode)){   try {    PrintWriter pw = response.getWriter();    pw.write("1");    pw.flush();   } catch (IOException e) {    e.printStackTrace();   }  } }}

实现bean对象示例：

@Entity@Table(name = "jcy_xhcx_grsq", schema = "")@SuppressWarnings("serial")public class XhcxGrsqEntity implements java.io.Serializable{ /**被查询人姓名*/ private java.lang.String grsqBcxry; /**主键*/ private java.lang.String id;
