springmvc

第一步，导入spring和hibernate的jar包(spring.jar, spring-webmvc.jar, commons-logging-1.0.4.jar。其他jar包为hibernate相关jar包)

第二步，项目配置文件web.xml

<?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">
	<display-name>springmvc_003_hibernate_xml</display-name>
	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>GBK</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<servlet>
		<servlet-name>dispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring-mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>dispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

第三步，springMVC配置文件spring-mvc.xml(里面包含hibernate的配置信息)

<?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:tx="http://www.springframework.org/schema/tx"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
		http://www.springframework.org/schema/beans
		http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
		http://www.springframework.org/schema/tx
		http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
		http://www.springframework.org/schema/aop

	<tx:advice id="txAdvice" transaction-manager="txManager">
		<tx:attributes>
			<tx:method name="find*" read-only="true" propagation="NOT_SUPPORTED" />

	<!-- servlet映射列表(这里employeeController为容器中com.test.controller.EmployeeController的bean名，它需要实现Controller中的handleRequest方法) -->
	<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

	<bean id="employeeController" class="com.test.controller.EmployeeController">

	<bean id="employeeService" class="com.test.service.EmployeeService">

	</bean>
	
	<bean id="employeeDao" class="com.test.dao.EmployeeDao">
		<property name="hibernateTemplate" ref="hibernateTemplate"></property>
	</bean>

</beans>

第四步，实体类Employee.java

package com.test.model;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class Employee {
	@Id
	@GeneratedValue
	private int id;
	private String name;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

}

第五步，DAO层EmployeeDao.java

package com.test.dao;

import org.springframework.orm.hibernate3.HibernateTemplate;

import com.test.model.Employee;

public class EmployeeDao {
	private HibernateTemplate hibernateTemplate;

	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}

	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}

	public void add(Employee employee) {
		hibernateTemplate.save(employee);
	}

}

第六步，service层EmployeeService.java

package com.test.service;

import com.test.dao.EmployeeDao;
import com.test.model.Employee;

public class EmployeeService {
	private EmployeeDao employeeDao;

	public EmployeeDao getEmployeeDao() {
		return employeeDao;
	}

	public void setEmployeeDao(EmployeeDao employeeDao) {
		this.employeeDao = employeeDao;
	}

	public void add(String name) {
		Employee employee = new Employee();
		employee.setName(name);
		employeeDao.add(employee);
	}
}

第七步，控制器HelloController.java

package com.test.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import com.test.service.EmployeeService;

public class EmployeeController implements Controller {

	private EmployeeService employeeService;

	public EmployeeService getEmployeeService() {
		return employeeService;
	}

	public void setEmployeeService(EmployeeService employeeService) {
		this.employeeService = employeeService;
	}

	@Override
	public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
		// get提交时，这里需要转码，post提交不需要转码
		String name = new String(request.getParameter("name").getBytes("iso8859-1"), "GBK");
		request.setAttribute("name", name);
		employeeService.add(name);

		return new ModelAndView("result");
	}

}

第八步，在jsp目录下创建result.jsp文件

<%@ page language="java" contentType="text/html; charset=GBK"
    pageEncoding="GBK"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>结果</title>
</head>
<body>
	<h1><%=request.getAttribute("name") %></h1>
</body>
</html>

第九步，首页index.jsp文件

<%@ page language="java" contentType="text/html; charset=GBK"
    pageEncoding="GBK"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<title>首页</title>
</head>
<body>
	<form action="employee" method="get">
		<input type="text" name="name">
		<input type="submit" value="提交">
	</form>
</body>
</html>
