1、首先看下项目的目录结构：

2、我们看下web.xml的基本配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
	<web-app>
		<display-name>创业基金项目</display-name>

		<listener>
			<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
		</listener>

		<context-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring/applicationContext*.xml</param-value>
		</context-param>

		<servlet>
			<servlet-name>spring-mvc</servlet-name>
			<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
			<init-param>
				<param-name>contextConfigLocation</param-name>
				<param-value>classpath:spring/spring-mvc-servlet.xml</param-value>
			</init-param>
			<load-on-startup>1</load-on-startup>
		</servlet>

		<servlet-mapping>
			<servlet-name>spring-mvc</servlet-name>
			<url-pattern>/</url-pattern>
		</servlet-mapping>

		<welcome-file-list>
			<welcome-file>index.jsp</welcome-file>
		</welcome-file-list>
	</web-app>

3、接着看下配置文件的内容，目录如下：

现在看下dev.properties的内容，其他几个环境的一样：

ce_home=/user1/path

config.properties文件：

ce_home=${ce_home}

logback.xml的内容：

<configuration xmlns="http://ch.qos.logback/xml/ns/logback"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://ch.qos.logback/xml/ns/logback 
	https://raw.githubusercontent.com/enricopulatzo/logback-XSD/master/src/main/xsd/logback.xsd">

	<!-- 输出到控制台 -->
	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
		<!-- 输出的格式 -->
		<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
			<pattern>%d{yyyy-MM-dd-HH:mm:ss.SSS} %level	[%thread]-%class:%line>>%msg%n</pattern>
		</encoder>
	</appender>

	<root level="INFO">
		<appender-ref ref="STDOUT" />
	</root>
</configuration>

重点来了，看下Spring的配置文件，applicationContext.xml的内容：

<?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: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.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

	<context:property-placeholder location="classpath:*.properties" />

	<context:component-scan base-package="com.framework.fund">
		<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
	</context:component-scan>

	<!--发邮件的配置信息 -->
	<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="smtp.163.com" />
		<property name="port" value="25" />
		<property name="protocol" value="smtp" />
		<property name="username" value="[email protected]" />
		<property name="password" value="******" />
		<property name="defaultEncoding" value="UTF-8" />
		<property name="javaMailProperties">
			<props>
				<prop key="mail.smtp.auth">true</prop>
				<prop key="mail.smtp.timeout">25000</prop>
			</props>
		</property>
	</bean>
	<bean id="mailMessage" class="org.springframework.mail.SimpleMailMessage">
		<property name="from" value="[email protected]" />
	</bean>

</beans>

看下Spring mvc的配置文件spring-mvc-servlet.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.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">

	<mvc:annotation-driven />

	<context:component-scan base-package="com.framework.fund.controller" />

	<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

	<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
		<property name="messageConverters">
			<list>
				<bean class="org.springframework.http.converter.StringHttpMessageConverter">
					<property name="supportedMediaTypes">
						<list>
							<value>text/plain;charset=UTF-8</value>
						</list>
					</property>
				</bean>
			</list>
		</property>
	</bean>
	
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/pages/" />
		<property name="suffix" value=".jsp" />
	</bean>
	
</beans>

最后我们来看下maven的pom.xml的文件内容，经过自己精心排版，应该值得大家参考

<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/maven-v4_0_0.xsd">

现在我们写一个controller：

package com.framework.fund.controller;

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

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

@Controller
@RequestMapping(value ="/helloWorld",method = RequestMethod.GET)
public class HelloWorldController {
	
	@RequestMapping("/print")
	@ResponseBody
	public String  print(HttpServletRequest request,HttpServletResponse response){
		return "Hello World!";
	}

}

现在我们用jetty启动服务，我使用的eclipse，配置如下：

启动服务信息如下：

通过浏览器访问一下,结果如下：

虽然没有华丽的语言就描述项目的内容，但是贴出实际的代码大家一起用起来才有价值。
