package com.shashank.topic;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Topic {
@Id
private String id;
private String name;
private String description;
public Topic() {
}
public Topic(String id, String name, String description) {
super();
this.id = id;
this.name = name;
this.description = description;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
Repository is configured like this
package com.shashank.topic;
import org.springframework.data.repository.CrudRepository;
public interface TopicRepository extends CrudRepository<Topic, String> {
/***
* CURD OPERATIONS
* getAllTopics()
* getTopic(String id)
* updateTopic(Topic topic)
* deleteTopic(String id)
* */
}
This is another class
package com.shashank.topic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.ArrayList;
import java.util.List;
import java.util.Optional;
@Service
public class TopicService {
@Autowired
private TopicRepository topicRepository;
public List<Topic> getAllTopics() {
List<Topic> topics = new ArrayList<>();
topicRepository.findAll().forEach(topics::add);
return topics;
}
public Optional<Topic> getTopic(String id) {
return topicRepository.findById(id);
}
public void addTopic(Topic topic) {
topicRepository.save(topic);
}
public void updateTopic(String id, Topic topic) {
topicRepository.save(topic);
}
public void deleteTopic(String id) {
topicRepository.deleteById(id);
}
}
I’m able to post the topics in my table and get as well from the postman but when I try to use put, to update the contents of the table, nothing changes.
I was trying to put the below command to update the table
{
"id": "javascript",
"name": "Update javascript",
"description": "Update javascript Description"
}
where “javascript” was already in the table, with name as “javascript” and description as “javascript description”
Here is my spring console log

Answer
There is something unusual with your Id. Why did you consider Id as String?
It should be Long or int, So maybe your id is your main problem.
Also, It would be better that put the controller to help us to debug better. Anyway, there are some ideas.
public void updateTopic(String id, Topic topic) {
Topic myTopic = topicRepository.findById(id);
topicRepository.save(myTopic);
}
- Controller
@PutMapping("/topics")
private Topic update(@RequestBody Topic topic){
topicService.updateTopic(topic);
return topic;
}
- Strongly recommend you to change your ID from string to
intorLongand try the above solution.
