		</dependency>

		<!-- jstl -->
		<dependency>
			<groupId>javax.servlet</groupId>

	</dependencies>

2. application.properties 설정

# 주석문


server.port = 8080

#view에 해당하는 jsp의 위치와 확장자
spring.mvc.view.prefix=/WEB-INF/Views/
spring.mvc.view.suffix=.jsp

#서버자동 시작
spring.devtools.livereload.enabled=true

spring.data.mongodb.uri=mongodb://id318:pw318@1.234.5.158:37017/id318
spring.data.mongodb.database=id318
spring.jpa.hibernate.ddl-auto=update

3. Boot20210903Application 설정

package com.example.boot_20210903;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;

@EnableAutoConfiguration(exclude = { DataSourceAutoConfiguration.class })
@SpringBootApplication
@ComponentScan(basePackages = { "com.example.controller" })
@EntityScan(basePackages = { "com.example.entity" })
@EnableMongoRepositories(basePackages = { "com.example.repository" })

public class Boot20210903Application {

	public static void main(String[] args) {
		SpringApplication.run(Boot20210903Application.class, args);
		System.out.println("Hello world");
	}

}
