Maven搭建springMVC+spring+hibernate环境

2023-01-29 20:17:46

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

</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/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。
