从STS的下载到空项目的搭建
1.
下载STS，下载解压缩后点击sts-bundle文件夹中的STS文件启动ide；
2. 创建Spring MVC项目：File->New->Dynamic Web Project->输入Project name；
3. 添加Spring MVC所需要的jar包（网上下载，百度搜：“Spring MVC jar包下载”）：把所有的jar包都添加到WebContent/WEB-INF/lib目录下（lib文件夹手动创建）；
4. 添加
web.xml文件：在WebContent/WEB-INF目录下创建一个叫“web.xml”的文件；
5. 添加对应Servlet的xml文件：在Java Resources/src目录点击右键->New->Other->Spring Bean Configuration File->勾选“aop/beans/context/mvc”这四个->Finish（本章命名为“springmvc-servlet.xml”）。
至此Spring MVC空项目搭建完毕，接下来就是填充项目了。
*STS代码自动提示功能
1. Java代码自动补全：“Sprint Tool Suite->偏好设置->Java->Editor->Content Assist->Auto Activation->Enable auto activation->Auto activation triggers for Java:<=:.abcdefghijklmnopqrstuvwxyz(,”；
2. XML/HTML代码自动补全：把步骤1中的Java换成XML/HTML即可，方法相同。
项目填充
1.添加Controller文件（src/controller/HelloController.java）：
package controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HelloController {
@RequestMapping(value="/",method = RequestMethod.GET)
public String home(ModelMap model) {
model.addAttribute("message", "This is the homepage.");
return "index";
}
}
2. 添加View文件（WEB-INF/views/index.jsp）:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>主页面</title>
</head>
<body>
<h1>Message : ${message}</h1>
</body>
</html>
3. 填充Servlet的xml文件（src/springmvc-servlet.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:aop="http://www.springframework.org/schema/aop"
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/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
<mvc:annotation-driven/>
<context:component-scan base-package="controller"></context:component-scan>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
4. 填充“web.xml”文件：
<?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:aop="http://www.springframework.org/schema/aop"
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/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
<mvc:annotation-driven/>
<context:component-scan base-package="controller"></context:component-scan>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
5. 启动服务器，并访问homepage：
