首先配置web.xml，配置Spring的監聽器，用於初始化ApplicationContext對象：

<?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的監聽器，用於初始化ApplicationContext對象 -->  

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

</web-app>

而後配置ApplicationContext對象的參數：

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

而後添加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>

數據庫鏈接方式：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監控 -->
 <servlet>
  <servlet-name>Admin</servlet-name>
  <servlet-class>
   org.logicalcobwebs.proxool.admin.servlet.AdminServlet
  </servlet-class>
 </servlet>

監控url:

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

配置applicationContext.xml文件(在src目錄下)：

<?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，自動掃描與裝配bean：

<!-- 自動掃描與裝配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 獲取配置文件中定義的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>    
                   
                <!--格式化輸出sql語句-->    
                <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>    
         <!-- 註解方式配置 -->
  <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>
      <!--自動掃描實體 -->    
 <bean name="transactionManager"
  class="org.springframework.orm.hibernate4.HibernateTransactionManager">
  <property name="sessionFactory" ref="sessionFactory"></property>
 </bean>  
 <!-- 配置事務 -->
 <tx:annotation-driven transaction-manager="transactionManager" />

接下來，配置spring-mvc.xml(在src目錄下)：

<?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/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd ">

  <context:annotation-config />
 <!-- 自動掃描controller包下的全部類，使其認爲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" />

  <!-- 對模型視圖名稱的解析，即在模型視圖名稱添加先後綴 -->    
       <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目錄下) 文件內容以下：

<?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>

接下來是java MVC層的代碼示例：

DAO層：

首先定義接口：

public interface CommonDaoI {}

實現類：

@Repository("commonDao")
public class CommonDaoImpl implements CommonDaoI {
@Autowired
 private JdbcTemplate jdbcTemplate;
@Autowired
private SessionFactory sessionFactory;

//TODO 如下可自因爲添加操做數據庫的方法
}

Service層：

接口：

public interface CommonServiceI {}

實現類：

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

控制層：

@Controller
@RequestMapping("/commonAction.do")
public class CommonAction {
 
 @Autowired
 private CommonServiceI commonService ;

//檢查驗證碼是否正確，正確返回"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();
   }
  }
 }

}

實現bean對象示例：

@Entity
@Table(name = "jcy_xhcx_grsq", schema = "")
@SuppressWarnings("serial")
public class XhcxGrsqEntity implements java.io.Serializable{
 /**被查詢人姓名*/
 private java.lang.String grsqBcxry;
 /**主鍵*/
 private java.lang.String id;
 /**國籍/地區*/
 private java.lang.String grsqGjdq;
