My first Spring Boot application with MySQL and JPA is shutting down immediately and I do not have any clue on the reasons.

I am also adding the SpringBoot annotated class below
package com.classpath;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SampleAppApplication {
public static void main(String[] args) {
SpringApplication.run(SampleAppApplication.class, args);
}
}
Please let me know where I am going wrong and how to debug this issue. Seems like Spring is doing too much magic here.
回答1:
What about your database dependency? Configure an embedded database (H2, HSQL or Derby) or another relational database like oracle or mysql dependency inside pom.xml.
Example:
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>
