### 步骤一：使用Spring Initializr创建SpringBoot项目 ###

### 步骤二： 补充web缺少的项目文件夹 ###

再创建一个主页index.jsp最终得到如下目录结构：

### 步骤三：部署到外部tomcat运行  ###

###  步骤四：支持jsp ###

1）、主配置文件中添加

spring.mvc.view.prefix=/WEB-INF/
    spring.mvc.view.suffix=.jsp

2）、编写代码测试

@Controller
    public class TestController {
        @GetMapping("test")
        public static String testJsp(){
            System.out.println("test");
            return "test";
        }
    }

3）、结果：

### 关键点总结： ###

1）、必须创建一个war项目；（利用idea创建好目录结构）

2）、将嵌入式的Tomcat指定为provided

<dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-tomcat</artifactId>
       <scope>provided</scope>
    </dependency>

3）、必须编写一个SpringBootServletInitializer的子类，并调用configure方法

public class ServletInitializer extends SpringBootServletInitializer {
    
       @Override
       protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
           //传入SpringBoot应用的主程序
          return application.sources(SpringBoot04WebJspApplication.class);
       }
    
    }

4）、启动服务器就可以使用了
