springboot部署到tomcat

1.创建maven工程，添加依赖，pom文件类容如下：

  4.0.0

  com.szcatic
  springboot
  0.0.1-SNAPSHOT
  war

  springboot
  http://maven.apache.org
    
  	
        org.springframework.boot
        spring-boot-starter-parent
        2.1.0.RELEASE
    
    
        
            org.springframework.boot
            spring-boot-starter-web
        
        
			org.springframework.boot
			spring-boot-starter-test
			test
		
        
		
		    org.junit.jupiter
		    junit-jupiter-engine
		    test
		
		
		    org.junit.platform
		    junit-platform-runner
		    test
		
    
    
        UTF-8
        UTF-8
        1.8
        
    	com.szcatic.Application
    
    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
                
	                1.8
	                1.8
	            
            
        
    

此处注意com.szcatic.Application 

2.创建应用程序入口类Application.java

package com.szcatic;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
@RestController
public class Application extends SpringBootServletInitializer {
	
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
		return application.sources(Application.class);
	}
	
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
	
	@RequestMapping("/hello")
    public String getHello() {
		return "Hello World";
    }
	
}

3.添加项目到tomcat服务

4.启动tomcat服务，控制台类容如下
