Somehow I cant save courses...
This is my DatabaseLoader class:
package com.teamtreehouse.core;
import com.teamtreehouse.course.Course;
import com.teamtreehouse.course.CourseRepository;
import com.teamtreehouse.review.Review;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.IntStream;
@Component
public class DatabaseLoader implements ApplicationRunner {
private final CourseRepository courses;
@Autowired
public DatabaseLoader(CourseRepository courses) {
this.courses = courses;
}
@Override
public void run(ApplicationArguments args) throws Exception {
Course course = new Course("Java Basics", "http://www.testurl.com/java-basics");
course.addReview(new Review(3, "You ARE a dork!!!"));
courses.save(course);
String[] templates = {
"Up and Running with %s",
"%s Basics",
"%s for Beginners",
"%s for Neckbeards",
"Under the hood: %s"
};
String[] buzzwords = {
"Spring REST Data",
"Java 9",
"Groovy",
"Scala",
"Hibernate"
};
List<Course> bunchOfCourses = new ArrayList<>();
IntStream.range(0, 100)
.forEach(i -> {
String template = templates[i % templates.length];
String buzzword = buzzwords[i % buzzwords.length];
String title = String.format(template, buzzword);
Course c = new Course(title, "http://www.example.com");
c.addReview(new Review(i % 5, String.format("Moar %s please", buzzword)));
bunchOfCourses.add(c);
});
courses.save(bunchOfCourses);
}
}
And this is the error message I get :
Error:(56, 16) java: method save in interface org.springframework.data.repository.CrudRepository<T,ID> cannot be applied to given types;
required: S
found: java.util.List<com.teamtreehouse.course.Course>
reason: inferred type does not conform to upper bound(s)
inferred: java.util.List<com.teamtreehouse.course.Course>
upper bound(s): com.teamtreehouse.course.Course
I just don't get why this is happening.

I think this maybe because save()
is looking for a single Entity, I am guessing a non-iterable object. So maybe instead of using save()
, you can try again with saveAll()
, since saveAll()
takes an Iterable entity, which is what this Course object appears to be.

8,349 PointsThe thing which is weird is, that even if I comment out the new lines. It gives me that error. Even though it was working fine.

8,349 PointsThe old 'turning it off and on' fixed the problem. Seems like even though I closed IntelliJ and terminated the App running the server somehow kept running in the background. After a reboot it started without any troubles.

8,349 PointsThanks for the answer! It seems like that actually was the problem, but now the server won't start anymore.(I don't think it's related to the
saveAll()
). Im probably gonna investigate further tomorrow. Was already in bed but had to try it because it was really bugging me that I coulnd't figure it out.Dane Parchment
