首先介绍下我的开发工具是:Eclipse,项目配置的机构如图：

![SouthEast][]

二、在web.xml文件的内容如下：

<?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" 
    	xmlns="http://java.sun.com/xml/ns/javaee" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
      
      <context-param>
       <param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/applicationContext.xml,/WEB-INF/springmvc-servlet.xml</param-value>
      </context-param>
      
      <listener>
      	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      <servlet>
      	<servlet-name>springMVC</servlet-name>
      	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      	
      	<init-param>
      		<param-name>contextConfigLocation</param-name>
      		<param-value>classpath:config/springmvc-servlet.xml</param-value>
      	</init-param>
      	<load-on-startup>1</load-on-startup>
      </servlet>
      <servlet-mapping>
      	<servlet-name>springMVC</servlet-name>
      	<url-pattern>/</url-pattern>
      </servlet-mapping>
      
      <filter>
      	<filter-name>encodingFilter</filter-name>
      	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
      </filter>
      <filter-mapping>
      	<filter-name>encodingFilter</filter-name>
      	<url-pattern>/*</url-pattern>
      </filter-mapping>
    </web-app>

三、配置springmvc文件，springmvc-servlet.xml 文件如下：

<?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans" 
    	xmlns:context="http://www.springframework.org/schema/context" 
    	xmlns:mvc="http://www.springframework.org/schema/mvc"
    	xmlns:p="http://www.springframework.org/schema/p"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        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.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
        
       <context:component-scan base-package="net.zdsoft.eis"/>
       
       
       <context:annotation-config />
       
       
       <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
       <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
       
       
       
    	<mvc:resources location="/img/" mapping="/img/**"/>
    	<mvc:resources location="/js/" mapping="/js/**"/>
    	
        
        
    	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<property name="prefix" value="/"/>
    		<property name="suffix" value=".jsp"/>
    	</bean>
    	
    	
    	
    </beans>

四、hibernate.cfg.xml文件内容如下：

<?xml version='1.0' encoding='UTF-8'?>
    <!DOCTYPE hibernate-configuration PUBLIC
              "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
              "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
    
    
    <hibernate-configuration>
    
    	<session-factory>
    		<mapping resource="com/css/model/Emp.hbm.xml" />
    	</session-factory>
    
    </hibernate-configuration>

五、hibernate.properties数据库的字典内容如下：

dataSource.dialect=org.hibernate.dialect.OracleDialect
    dataSource.driverClassName=oracle.jdbc.driver.OracleDriver
    dataSource.url=jdbc\:oracle\:thin\:@localhost\:1521\:orcl
    dataSource.username=springmvc
    dataSource.password=springmvc
    dataSource.hbm2ddl.auto=update
    dataSource.show_sql=true

六、springMVC.properties配置如下：

uploadDir=upload

七、applicationContext.xml配置文件如下：

<?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: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">
    	<context:component-scan base-package="com.css.*" />
    	<context:property-placeholder location="classpath:/hibernate.properties" />
    	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    		<property name="driverClassName">
    			<value>${dataSource.driverClassName}</value>
    		</property>
    		<property name="username">
    			<value>${dataSource.username} </value>
    		</property>
    		<property name="password">
    			<value>${dataSource.password} </value>
    		</property>
    		<property name="url">
    			<value>${dataSource.url}</value>
    		</property>
    	</bean>
    	<bean id="sessionFactory"
    		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    		<property name="dataSource" ref="dataSource" />
    		<property name="configLocation" value="classpath:hibernate.cfg.xml" />
    		<property name="hibernateProperties">
    			<props>
    				<prop key="hibernate.dialect">${dataSource.dialect}</prop>
    				<prop key="hibernate.hbm2ddl.auto">${dataSource.hbm2ddl.auto}</prop>
    				<prop key="hibernate.show_sql">${dataSource.show_sql}</prop>
    			</props>
    		</property>
    	</bean>
    	
    	<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
    		<property name="sessionFactory" ref="sessionFactory"></property>
    	</bean>
    	
    	<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    		<property name="dataSource" ref="dataSource" />
    	</bean>
    </beans>

八、实体类Emp.java的内容如下：

package com.css.model;
    
    import java.sql.Timestamp;
    
    import javax.persistence.Entity;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    
    
    /**
     * Emp entity. @author MyEclipse Persistence Tools
     */
    @Entity
    public class Emp implements java.io.Serializable {
    
    	// Fields
    	@Id
    	@GeneratedValue(strategy=GenerationType.AUTO)
    	private Short empno;
    	private String ename;
    	private String job;
    	private Short mgr;
    	private Timestamp hiredate;
    	private Double sal;
    	private Double comm;
    	private Byte deptno;
    
    	// Constructors
    
    	/** default constructor */
    	public Emp() {
    	}
    
    	/** full constructor */
    	public Emp(String ename, String job, Short mgr, Timestamp hiredate,
    			Double sal, Double comm, Byte deptno) {
    		this.ename = ename;
    		this.job = job;
    		this.mgr = mgr;
    		this.hiredate = hiredate;
    		this.sal = sal;
    		this.comm = comm;
    		this.deptno = deptno;
    	}
    
    	// Property accessors
    
    	此处省略set和get方法......
    }

九、实体类的配置文件Emp.hbm.xml内容如下：

<?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
    
    <hibernate-mapping>
        <class name="com.css.model.Emp" table="EMP" schema="SPRINGMVC">
            <id name="empno" type="java.lang.Short">
                <column name="EMPNO" precision="4" scale="0" />
                <generator class="sequence" />
            </id>
            <property name="ename" type="java.lang.String">
                <column name="ENAME" length="10" />
            </property>
            <property name="job" type="java.lang.String">

            </property>
            <property name="sal" type="java.lang.Double">
                <column name="SAL" precision="7" />
            </property>
            <property name="comm" type="java.lang.Double">
                <column name="COMM" precision="7" />
            </property>
            <property name="deptno" type="java.lang.Byte">
                <column name="DEPTNO" precision="2" scale="0" />
            </property>
        </class>
    </hibernate-mapping>

十、DAO的实现方法EmpDAO.java 内容如下：

package com.css.dao;
    
    import java.util.List;
    
    import javax.annotation.Resource;
    
    import org.hibernate.LockMode;
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.context.ApplicationContext;
    import org.springframework.orm.hibernate3.HibernateTemplate;
    import org.springframework.stereotype.Repository;
    
    import com.css.model.Emp;
    
    
    @Repository("empDAO")
    public class EmpDAO {
    	@Resource
    	private HibernateTemplate hibernateTemplate;
    	
    	
    
    	public HibernateTemplate getHibernateTemplate() {
    		return hibernateTemplate;
    	}
    
    	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
    		this.hibernateTemplate = hibernateTemplate;
    	}
    
    	
    	
    	private static final Logger log = LoggerFactory.getLogger(EmpDAO.class);

    		}
    	}
    
    	public void delete(Emp persistentInstance) {

    			log.debug("delete successful");
    		} catch (RuntimeException re) {
    			log.error("delete failed", re);
    			throw re;
    		}
    	}
    
    	public Emp findById(java.lang.Short id) {
    		log.debug("getting Emp instance with id: " + id);
    		try {
    			Emp instance = (Emp) getHibernateTemplate().get("com.css.dao.Emp",
    					id);
    			return instance;
    		} catch (RuntimeException re) {
    			log.error("get failed", re);
    			throw re;
    		}
    	}
    
    	public List findByExample(Emp instance) {
    		log.debug("finding Emp instance by example");
    		try {
    			List results = getHibernateTemplate().findByExample(instance);
    			log.debug("find by example successful, result size: "
    					+ results.size());
    			return results;
    		} catch (RuntimeException re) {
    			log.error("find by example failed", re);
    			throw re;
    		}
    	}
    
    	public List findByProperty(String propertyName, Object value) {
    		log.debug("finding Emp instance with property: " + propertyName
    				+ ", value: " + value);
    		try {
    			String queryString = "from Emp as model where model."
    					+ propertyName + "= ?";
    			return getHibernateTemplate().find(queryString, value);
    		} catch (RuntimeException re) {
    			log.error("find by property name failed", re);
    			throw re;
    		}
    	}
    
    	public List findByEname(Object ename) {
    		return findByProperty(ENAME, ename);
    	}
    
    	public List findByJob(Object job) {
    		return findByProperty(JOB, job);
    	}
    
    	public List findByMgr(Object mgr) {
    		return findByProperty(MGR, mgr);
    	}
    
    	public List findBySal(Object sal) {
    		return findByProperty(SAL, sal);
    	}
    
    	public List findByComm(Object comm) {
    		return findByProperty(COMM, comm);
    	}
    
    	public List findByDeptno(Object deptno) {
    		return findByProperty(DEPTNO, deptno);
    	}
    
    	public List findAll() {
    		log.debug("finding all Emp instances");
    		try {
    			String queryString = "from Emp";
    			return getHibernateTemplate().find(queryString);
    		} catch (RuntimeException re) {
    			log.error("find all failed", re);
    			throw re;
    		}
    	}
    
    	public Emp merge(Emp detachedInstance) {
    		log.debug("merging Emp instance");
    		try {
    			Emp result = (Emp) getHibernateTemplate().merge(detachedInstance);
    			log.debug("merge successful");
    			return result;
    		} catch (RuntimeException re) {
    			log.error("merge failed", re);
    			throw re;
    		}
    	}
    
    	public void attachDirty(Emp instance) {
    		log.debug("attaching dirty Emp instance");
    		try {
    			getHibernateTemplate().saveOrUpdate(instance);

    		}
    	}
    
    	public void attachClean(Emp instance) {
    		log.debug("attaching clean Emp instance");
    		try {
    			getHibernateTemplate().lock(instance, LockMode.NONE);
    			log.debug("attach successful");
    		} catch (RuntimeException re) {
    			log.error("attach failed", re);
    			throw re;
    		}
    	}
    
    	public static EmpDAO getFromApplicationContext(ApplicationContext ctx) {
    		return (EmpDAO) ctx.getBean("EmpDAO");
    	}
    }

十一、service层的方法此处暂不列出了，方法名称内容如DAO层的内容。

十二、此处列出controller中的几个控制类的内容：

package com.css.contorller;
    
    import java.util.HashMap;
    import java.util.Map;
    
    import javax.annotation.Resource;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.ModelAndView;
    
    import com.css.service.ServiceS;
    @Controller
    
    public class Login {
    	@Resource
    	private ServiceS serviceS;
    	@RequestMapping("/test.do")
    	public ModelAndView query()
    	{
    		Map<String, Object> prames = new HashMap<String, Object>();
    		prames.put("lists", serviceS.find());
    		ModelAndView model = new ModelAndView("list",prames);
    		return model;
    	}
    }

package net.zdsoft.eis.controller;
    
    import javax.annotation.Resource;
    import javax.servlet.http.HttpServletRequest;
    
    import net.zdsoft.eis.dao.User;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.servlet.ModelAndView;
    import org.springframework.web.servlet.view.RedirectView;
    
    
    @Controller  //类似Struts的Action
    public class TestController {
    
        @RequestMapping("test/login.do")  // 请求url地址映射，类似Struts的action-mapping
        public String testLogin(@RequestParam(value="username")String username, String password, HttpServletRequest request) {
            // @RequestParam是指请求url地址映射中必须含有的参数(除非属性required=false)
            // @RequestParam可简写为：@RequestParam("username")
    
            if (!"admin".equals(username) || !"admin".equals(password)) {
                return "loginError"; // 跳转页面路径（默认为转发），该路径不需要包含spring-servlet配置文件中配置的前缀和后缀
            }
            return "loginSuccess";
        }
    
        @RequestMapping("/test/login2.do")
        public ModelAndView testLogin2(String username, String password, int age){
            // request和response不必非要出现在方法中，如果用不上的话可以去掉
            // 参数的名称是与页面控件的name相匹配，参数类型会自动被转换
            
            if (!"admin".equals(username) || !"admin".equals(password) || age < 5) {
                return new ModelAndView("loginError"); // 手动实例化ModelAndView完成跳转页面（转发），效果等同于上面的方法返回字符串
            }
            return new ModelAndView(new RedirectView("../index.jsp"));  // 采用重定向方式跳转页面
            // 重定向还有一种简单写法
            // return new ModelAndView("redirect:../index.jsp");
        }
    
        @RequestMapping("/test/login3.do")
        public ModelAndView testLogin3(User user) {
            // 同样支持参数为表单对象，类似于Struts的ActionForm，User不需要任何配置，直接写即可
            String username = user.getUsername();
            String password = user.getPassword();
            int age = user.getAge();
            
            if (!"admin".equals(username) || !"admin".equals(password) || age < 5) {
                return new ModelAndView("loginError");
            }
            return new ModelAndView("loginSuccess");
        }
    
    //    @Resource(name = "loginService")  // 获取applicationContext.xml中bean的id为loginService的，并注入
    //    private LoginService loginService;  //等价于spring传统注入方式写get和set方法，这样的好处是简洁工整，省去了不必要得代码
    
    //    @RequestMapping("/test/login4.do")
    //    public String testLogin4(User user) {
    //        if (loginService.login(user) == false) {
    //            return "loginError";
    //        }
    //        return "loginSuccess";
    //    }
    }

package net.zdsoft.eis.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    
    @Controller
    @RequestMapping("/test2/login.do")  // 指定唯一一个*.do请求关联到该Controller
    public class TestController2 {
        
        @RequestMapping
        public String testLogin(String username, String password, int age) {
            // 如果不加任何参数，则在请求/test2/login.do时，便默认执行该方法
            
            if (!"admin".equals(username) || !"admin".equals(password) || age < 5) {
                return "loginError";
            }
            return "loginSuccess";
        }
    
        @RequestMapping(params = "method=1", method=RequestMethod.POST)
        public String testLogin2(String username, String password) {
            // 依据params的参数method的值来区分不同的调用方法
            
            // 可以指定页面请求方式的类型，默认为get请求
            System.out.println(username);
            if (!"admin".equals(username) || !"admin".equals(password)) {
                return "loginError";
