**1. 创建一个maven项目**

**2. 创建好项目之后，结构如下图，缺少src/main/java**

选择工程，右键，properties->java build path

自己新建/src/main/java的文件夹即可

**3. 配置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/maven-v4_0_0.xsd">
      <modelVersion>4.0.0</modelVersion>
      <groupId>com.test.springboot</groupId>
      <artifactId>SpringBootWeb</artifactId>
      <packaging>war</packaging>
      <version>0.0.1-SNAPSHOT</version>
      <name>SpringBootWeb Maven Webapp</name>
      <url>http://maven.apache.org</url>
      
      <parent>
      	<groupId>org.springframework.boot</groupId>
      	<artifactId>spring-boot-starter-parent</artifactId>
      	<version>1.4.1.RELEASE</version>
      </parent>
      
      <properties>
      	<java.version>1.8</java.version>
      </properties>
      
      <dependencies>
      
      	<dependency>
      		<groupId>org.springframework.boot</groupId>
      		<artifactId>spring-boot-starter-web</artifactId>
      	</dependency>
       
        <dependency>
          <groupId>javax.servlet</groupId>
          <artifactId>javax.servlet-api</artifactId>
          <scope>provided</scope>
        </dependency>
        
        <dependency>
          <groupId>javax.servlet</groupId>
          <artifactId>jstl</artifactId>
        </dependency>
         
          <dependency>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-tomcat</artifactId>
          <scope>provided</scope>
        </dependency>
        
        <dependency>
          <groupId>org.apache.tomcat.embed</groupId>
          <artifactId>tomcat-embed-jasper</artifactId>
          <scope>provided</scope>
        </dependency>
      </dependencies>
      
    </project>

**4. 将tomcat server加入eclipse（之前配置过可跳过）**

选择工程，右键，properties  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L01heWRheV9SYWZh_size_16_color_FFFFFF_t_70 6]  
下一步

选择finish即可。

**5. 更新项目**  
如果项目有报错，查看problem，如果报需要更新的错，则选中项目，右键，maven->update project来更新项目

**6. 配置application.properties**  
src/main/resources下新建application.properties

server.port=80
    #\u914D\u7F6E\u524D\u7F00
    spring.mvc.view.prefix=/WEB-INF/jsp/
    #\u914D\u7F6E\u540E\u7F00
    spring.mvc.view.suffix=.jsp

**7.编写jsp页面和java代码**  
WEB/INF下新建jsp页面hello.jsp

<%@ page language="java" contentType="text/html; charset=utf-8"
        pageEncoding="utf-8"%>
    <!DOCTYPE html>
    <html>
    <head>
    <meta charset="utf-8">
    <title>Insert title here</title>
    </head>
    <body>
    <h1>欢迎来到SpringBootWeb世界</h1>
    <p>
    ${hismg }
    </p>
    </body>
    </html>

src/main/java下新建Controller.java和App.java  
Controller.java

package cn.springboot.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @Controller
    public class HelloController {
    	@RequestMapping("/hello")
    	public String Hello(Model model){
    		model.addAttribute("hismg", "welcom to HelloSpringWeb");
    		return "hello";
    	}
    }

App.java

package cn.itsource.springboot;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication//标记为springboot应用
    public class App {
    	public static void main(String[] args) {
    		//启动应用
    		SpringApplication.run(App.class,args);
    	}
    }

**8.测试**  
选中main函数，右键run with springboot app
