title: How do I resolve No constructor with 0 arguments on @SpringBootApplication
body: <p>I'm running a Spring Boot App (4.3.5) in eclipse(STS 3.8.3) and getting the following error:</p>
  
  <p>Description Resource    Path    Location    Type
  No constructor with 0 arguments defined in class 'org.springframework.data.jpa.repository.support.JpaRepositoryFactoryBean' ProcessCardEvents.java  /field-card/src/main/java/ws/daley/field/fieldcard  Unknown Spring Beans Problem</p>
  
  <p>Here's my program:</p>
  
  <pre><code>package ws.daley.field.fieldcard;
  
  import org.springframework.boot.autoconfigure.SpringBootApplication;
  
  @SpringBootApplication
  public class ProcessCardEvents
  {
  }
  </code></pre>
  
  <p>Actually there was a bunch more, but I stripped it down. There is an error marker on the java file in Package Explorer and error marker on the tab in the source pane, but no line is marked with an error.</p>
