Maven搭建springMVC+spring+hibernate实现用户注册

       之前写过《Maven搭建Struts2+spring+hibernate环境》系列，这次不再使用struts2做控制器，采用spring自己的springMVC框架实现。关于struts2+spring+hibernate的整合请看：http://blog.csdn.net/sgl731524380/article/details/8871446

首先，改写pom.xml文件，不需要struts2的相关jar了。

pom.xml

	</build>
</project>

删除struts.xml,新建spring-mvc.xml.

spring-mvc.xml

<?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">

	<!-- 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.sgl.controller" />

	<!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
	<bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
		<property name="supportedMediaTypes">
			<list>
				<value>text/html;charset=UTF-8</value>
			</list>
		</property>
	</bean>

	<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
			</list>
		</property>
	</bean>

	<!-- 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" >
		<property name="prefix" value="/" />
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

删除action包，新建controller包，建UserController.java

UserController.java

package com.sgl.controller;

import java.util.Date;
import java.util.UUID;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.sgl.model.User;
import com.sgl.service.UserService;

@Controller
public class UserController {
	@Autowired
	private UserService userService;
	@RequestMapping("/reg")
	public String register(){
		return "index";
	}
	@RequestMapping("/user")
	public ModelAndView addUser(User user) {
		ModelAndView mav=null;
		user.setId(UUID.randomUUID().toString());
		user.setRegtime(new Date());
		try {
			userService.addUser(user);
		//	request.setAttribute("user", user);
			mav = new ModelAndView();
			mav.setViewName("success");
			mav.addObject("user", user);
			mav.addObject("msg", "注册成功了，可以去登陆了");
			return mav;
		} catch (Exception e) {
			mav.setViewName("error");
			mav.addObject("user", null);
			mav.addObject("msg", "注册失败");
			return mav;
		}
	}

}

最后修改web.xml文件，删除其中struts2的配置，增加springMVC的配置。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
	<display-name></display-name>

	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring.xml,classpath:spring-hibernate.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	<!-- springMVC 配置 -->
	<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>
	<!-- 拦截以html为后缀的请求 -->
	<servlet-mapping>
		<servlet-name>springMvc</servlet-name>
		<url-pattern>*.html</url-pattern>
	</servlet-mapping>
	<session-config>
		<session-timeout>10</session-timeout>
	</session-config>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

所有的配置文件完成后，项目结构如下：

执行Maven install,没有错误，部署到服务器上，启动服务器，浏览器输入http://localhost:8080/MSSH/reg.html回车

至于为什么要是输入这个地址，请仔细查看UserController.java的@RequestMapping注解的配置，这是属于spingMVC的注解，在此不再详述其拦截-转发的过程。

点击注册，注意浏览器地址的变化:

springMVC+spring+hibernate实现用户注册完成了。其中User的password我没有写，忘记持久到数据库了，需要的可以在User.java中加上password属性和set/get方法。毕竟这个MSSH项目只是演示如何搭建ssh框架，不是真实的项目。要是真实项目这样做，恐怕饭碗都要丢了。。
