用Eclipse 搭建一个Maven Spring SpringMVC 项目

 

1： 先创建一个maven web  项目：

可以参照之前的文章：  用Maven 创建一个 简单的 JavaWeb 项目

创建好之后的目录是这样的;

2: 先配置maven  修改pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

3: 修改web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" 
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" 
id="WebApp_ID" version="3.1">

<display-name>mss01</display-name>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
<!-- 加載順序: 上下文参数  >>> 监听器  >>> 过滤器  >>> 拦截器  -->

<!-- 日志记录 -->
<context-param>
<!-- 日志配置文件路径 -->
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:config/properties/log4j.properties</param-value>
</context-param>
<context-param>
<!-- 日志页面的刷新间隔 -->
<param-name>log4jRefreshInterval</param-name>
<param-value>6000</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:config/xml/application.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<filter>
<filter-name>encoding</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>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 配置静态资源映射,防止静态资源被拦截后导致controller返回的页面的js,css失效   这是第一种方式  还有一个方式在spring-mvc.xml中 -->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>*.js</url-pattern>
<url-pattern>*.css</url-pattern>
<url-pattern>/assets/*"</url-pattern>
<url-pattern>/images/*</url-pattern>
</servlet-mapping>
<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/xml/spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
<async-supported>true</async-supported>
</servlet>

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!-- 设置session 存活时长  60 min  -->
<session-config>
<session-timeout>60</session-timeout>
</session-config>
</web-app>

4: 根据web.xml 添加一些文件:

再添加文件之前先来一张添加好之后的项目架构:

下面是: application.xml

<?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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc 
       http://www.springframework.org/schema/mvc/spring-mvc.xsd 
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd 
       http://www.springframework.org/schema/aop 
       http://www.springframework.org/schema/aop/spring-aop.xsd 
       http://www.springframework.org/schema/tx 
       http://www.springframework.org/schema/tx/spring-tx.xsd
       ">
<!-- 上面没有带上版本号 系统会自动匹配合适的 -->

<!-- 采用注释的方式配置bean -->
<context:annotation-config />
<!-- 自动扫描注解 -->
<context:component-scan base-package="com.etoak.mss" />

<!-- 因为是简单的maven Spring SpringMvc  项目 所以 也就没有配置 数据源之类的; -->

</beans>

下面是: sring-mvc.xml

<?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:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.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.xsd" >
<!-- 上面没有带上版本号 系统会自动匹配合适的 -->


<!-- 开启注解模式驱动 -->
<mvc:annotation-driven></mvc:annotation-driven>

<!-- 自动扫描web包 ,将带有注解的类 纳入spring容器管理 -->
<context:component-scan base-package="com.etoak.mss"/>

<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>

<!-- 默认的注解映射的支持 -->
<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/plain;charset=utf-8</value>
<value>application/json;charset=utf-8</value>
<value>application/x-www-form-urlencoded</value>
</list>
<!-- 设置 这些是为了 IE 浏览器 ajax 请求返回 json时  变成下载 -->
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>    

<!--配置静态资源映射,防止静态资源被拦截后导致controller返回的页面的js,css失效   这是第二种方式  还有一种方式在web.xml中 -->
<!-- <mvc:resources location="/static/css/" mapping="/css/**"></mvc:resources>
    <mvc:resources location="/static/js/" mapping="/js/**"></mvc:resources>
    <mvc:resources location="/static/images/" mapping="/images/**"/> -->
</beans>

为了体现出spring mvc 的作用  写了两个jsp页面 (index.jsp 和 welcome.jsp);

其中 index.jsp 放置在webapp 目录下面 可以直接访问 ; welcome.jsp放置在 WEB-INF 目录下面 只能通过 controller 跳转来访问.

先来张图:

下面是index.jsp的代码:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String welcomePagePath = basePath+"index/welcome";
%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Index Page</title>
</head>
<body>
    This is index page .
<br/>
    <br/>
    <a href="<%=welcomePagePath %>"> Click on me to go to welcome page . </a>
</body>
</html>

这是 welcome.jsp的代码

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Welcome Page </title>
</head>
<body>
    This is welcome page .
</body>
</html>

下面就是处理请求,控制跳转的controller了

package com.etoak.mss.welcome.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping(value="/index")
public class WelcomeController {


    @RequestMapping(value="/welcome",method=RequestMethod.GET)
public String welcome(){
        System.out.println("进来了!");
return "welcome";
    }
}

ok  至此 整个项目 已经搭建完成:

先进行两个Maven 操作:clean 和 install ;

然后再在tomcat 上运行;

是不是看到下面的页面?

控制台 也打印了 

 

 好了 上面就是 maven  和 Spring  SpringMvc  的整合 ;

接下来 准备再写一个 maven  spring spring Mvc  mybatis 整合项目;
