Simple spring-boot application with pom.xml and app.java is showing build failed error

Question

I am new in Java and I am trying to do a sample Spring Boot application. I am using eclipse IDE and Java 8. Created a Maven project with maven-archetype-quickstart archetype. In the pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" 
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

 <modelVersion>4.0.0</modelVersion>

<groupId>com.demo</groupId>
<artifactId>StormpathSpringBoot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

 <properties>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

</dependencies>

 </project>

In App.java

package com.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App 
{
    public static void main( String[] args )
{
    SpringApplication.run(App.class, args);
}
}

Then I run the application RunAs--> Maven Build goal-> spring-boot:run

Don't know this is the right way to run this application

I am getting error

Answer 1

To run you can: in eclipse right click on project -> run as -> Java application

I use Eclipse based IDE STS - it is usually better for Spring as here initial configs are up to date and better tested

Error states, that there is no JPA mappings defined. You have to define them or delete depedndencies from POM

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-rest</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

Answer 2

You are including spring-boot-starter-data-rest as a dependency. So there is a default controller with it ( ProfileController ), which is scanned at Spring context startup.

This controller has dependencies to other beans, one of which ( jpaMappingContext ) require a JPA configuration I guess.

Just remove this dependency and it should be fine.

Answer 3

As already mention in comment/answer- You have added the dependency for Spring JPA but did not add any entities in the project. You can remove this and try.

<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency>

Probably the best place to start a spring-boot project is to use spring initializr. https://start.spring.io/
