I have simple application that is trying consume Rest service:
#SpringBootApplication
public class ConsumingRestApplication
{
private static final Logger log = LoggerFactory.getLogger(ConsumingRestApplication.class);
public static void main(String[] args)
{
SpringApplication.run(ConsumingRestApplication.class, args);
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder)
{
return builder.build();
}
#Bean
public CommandLineRunner run(RestTemplate restTemplate) throws Exception
{
return args -> {
try
{
restTemplate.getForObject("https://gturnquist-quoters.cfapps.io/api/random", Quote.class);
} catch (RestClientException e)
{
e.printStackTrace();
}
};
}
}
Quote class:
#JsonIgnoreProperties(ignoreUnknown = true)
public class Quote {
private String type;
private Value value;
public Quote() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Value getValue() {
return value;
}
public void setValue(Value value) {
this.value = value;
}
#Override
public String toString() {
return "Quote{" +
"type='" + type + '\'' +
", value=" + value +
'}';
}
}
Got error :
org.springframework.web.client.UnknownContentTypeException: Could not extract response: no suitable HttpMessageConverter found for response type [class com.example.consumingrest.Quote] and content type [application/json;charset=UTF-8]

What is starting point o solving this problem? What logic I should go to find problem?
I believe you are missing Value object or must be a wrong import. Along with that you need to add getter methods for the field if they are private, when you are returning that object directly in the response, here is how i have done it:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
#RestController
public static class Test {
#Autowired
private RestTemplate restTemplate;
#GetMapping
public Quote test() {
return restTemplate.getForObject("https://gturnquist-quoters.cfapps.io/api/random", Quote.class);
}
}
public static class Quote {
private String type;
private Value value;
public String getType() {
return type;
}
public Value getValue() {
return value;
}
}
public static class Value {
private Long id;
private String quote;
public Long getId() {
return id;
}
public String getQuote() {
return quote;
}
}
}

I implemented a simple Spring Boot application using the following classes:
Application Class:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
#ComponentScan(basePackageClasses = CustomerController.class)
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
Model Class:
public class Customer {
private Long id;
private String Name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
}
Controller Class:
#RestController
public class CustomerController {
#RequestMapping(name="/customer", method=RequestMethod.GET)
public Customer getCustomer(#RequestParam Long id) {
Customer cust = new Customer();
cust.setId(id);
cust.setName("George");
return cust;
}
#RequestMapping(name="/customer", method=RequestMethod.POST, consumes = "application/json")
public Customer createCustomer(#RequestBody Customer cust) {
return cust;
}
}
The application was initiated as Spring Boot and produced the following logs:

When i start postman invoke the following:
GET http://localhost:8080/customer?id=1
and i get the following error:
{
"timestamp": "2022-09-14T10:28:27.548+00:00",
"status": 404,
"error": "Not Found",
"path": "/customer"
}
Your #RequestMapping annotation should use value="customer" instead of name="customer".
Better practice is to annotate the CustomerController with #RestController and #ReqeustMapping("/customer") and mark the getCustomer method with #GetMapping, and the create Customer with #PostMapping
Like example my PostMapping:
#Controller
public class MainController {
#PostMapping("/mainaho")
public String addAho (
#RequestParam String owner,
#RequestParam String text,
#RequestParam String sn,
#RequestParam String invid,
#RequestParam String author, Map<String, Object> model) throws WriterException {
AddTmcAho addTmcAho = new AddTmcAho();
addTmcAho.addTmcAho(ahoRepo, owner, text, sn, invid, author, model);
return "mainaho";
}
}
I train with springboot and a mariadb database. When I test for data recovery, I get this message in postman:
{
"timestamp": "2022-03-03T13:53:18.609+00:00",
"status": 404,
"error": "Not Found",
"path": "/user/all"
}
. I tried several tutorials in copy paste and I always have the same message. I will also put the message that is in the console. Thank you in advance for your help.

Every thing on the controller class is implemented properly and there is definitely no need for other layers implementation to share, you probably use SpringBootServletInitializer, in the main class add the #EnableWebMvc annotation and override SpringApplicationBuilder method as
#SpringBootApplication
#EnableWebMvc
public class Application extends SpringBootServletInitializer {
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
Otherwise if you use SpringApplication to sun the project make sure the main class annotated with #SpringBootApplication and be some thing like
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
And final thing check the presence of spring boot starter web dependency in you pom file
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
If you do not use spring boot parent do not forget to add the proper version to web starter artifact.
I'm actually defining login with websecurity enabled, and i don't really know what is wring with my annotations that don't allow me to continue testing...

}
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"

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 int or Long and try the above solution.
I am making a basic application to send an insert to a database, as a test I have been executing a simple findAll () to test the repository, but it always gives me NullPointer
I am aware that it is something very basic and also that I am missing something.
Thank you.

you can not use autowire with static field unless you use postConstruct
Jpa needs defaut constructor so put it into your Data class
