点击Next

## 第二步 ##

对项目进行配置，这里可以选择以war包的形式，点击Next  
以jar包的形式

在这里插入图片描述  
以war包的形式  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 2]  
如果点击Next报错Artifact contains illegal characters  
把artifact改为小写就好了

## 第三步 ##

选择starter的窗口，这里可以选择我们需要的starter进行依赖

这里只选择web，spring web

点击finish

## 第五步：增加web的module ##

IDEA开始创建项目，在默认的项目结构中，增加  
src/main/webapp  
src/main/webapp/WEB-INF

点击File-Project Structure，添加web的module  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 7]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 8]  
添加web资源路径  
E:\\ideaWorkspace\\springboot\_study\_day01\\src\\main\\webapp  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 9]  
新增tomcat服务

新增web.xml  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 11]  
E:\\ideaWorkspace\\springboot\_study\_day01\\src\\main\\webapp\\WEB-INF\\web.xml  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N1bW1lcl9zdHlsZQ_size_16_color_FFFFFF_t_70 12]

## 第六步：增加JSP和JSTL的Maven依赖 ##

在pom增加JSP和JSTL的Maven依赖

<dependency>
                <groupId>org.apache.tomcat.embed</groupId>
                <artifactId>tomcat-embed-jasper</artifactId>
                <scope>provided</scope>
            </dependency>
            <dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>jstl</artifactId>
                <scope>provided</scope>
            </dependency>

pom.xml

                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    </project>

## 第七步：修改application.properties ##

# 端口
    server.port=8082
    # 上下路径
    server.servlet.context-path=/springBootStudyDay01
    # 配置视图解析器，定义视图前后缀
    spring.mvc.view.prefix=/WEB-INF/jsp/
    spring.mvc.view.suffix=.jsp

## 第八步：增加WEB-INF/jsp/index.jsp ##

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
    <html>
    <head>
        <title>Title</title>
    </head>
    <body>
    <h1>hello wrold</h1>
    </body>
    </html>

## 第八步：增加控制层代码 ##

@Controller
    @RequestMapping("/userController")
    public class UserController { 
    
        @RequestMapping(value = "getUser",method = RequestMethod.GET)
        public String getUser(){ 
            System.out.println("UserController getUser begin");
            return "index";
        }
    }

## 最终目录结构 ##

## 启动项目 ##

直接运行启动类SpringbootStudyDay01Application，就可以运行这个springBoot项目了

## 访问结果 ##

http://localhost:8082/springBootStudyDay01/userController/getUser
