Maven搭建springMVC+spring+hibernate环境

这次不再使用struts2做控制器，采用spring自己的springMVC框架实现。

首先，改写pom.xml文件，不需要struts2的相关jar了。

pom.xml

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"

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。
