Spring Boot + Spring Data + Spring MVC Encoding - java

As is clear from the topic of the question, this is my stack of technologies. I have a problem encoding Russian characters.
Its my controller:
#RestController
public class ProductController {
#Autowired
private ProductService productService;
#RequestMapping("/Product/ByQuery")
public List getProductsByQuery(#RequestHeader(name = "query" , required = false) String query) {
System.out.println(new String(query.getBytes(),StandardCharsets.ISO_8859_1));
return productService.findByQuery(new String(query.getBytes(),StandardCharsets.ISO_8859_1));
}
}
its my Service :
public class ProductServiceImpl implements ProductService {
#Autowired
private ProductRepository productRepository;
#Override
public List<Product> findByQuery(String query) {
List<DataModel.Product> productList = productRepository.findDistinctByNameContainingIgnoreCaseOrCategoryContainingIgnoreCaseOrManufacturerContainingIgnoreCaseOrInformationValueContainingIgnoreCase(query,query,query,query);
List<Product> resultProducts = new ArrayList<>();
ModelMapper modelMapper = new ModelMapper();
for (int i = 0; i < productList.size(); i++) {
int like = 0;
int dislike = 0;
for (Rating rating : productList.get(i).getRating()) {
if (rating.getType().equals("Like")) {
like += 1;
} else {
dislike += 1;
}
}
resultProducts.add(modelMapper.map(productList.get(i), Product.class));
resultProducts.get(i).setCommentCnt(productList.get(i).getComment().size());
resultProducts.get(i).setLike(like);
resultProducts.get(i).setDislike(dislike);
resultProducts.get(i).setImage(productList.get(i).getImage().get(0).getUrl());
}
return resultProducts;
}
}
Repository:
#Repository
public interface ProductRepository extends JpaRepository<Product,Long> {
List<Product> findDistinctByNameContainingIgnoreCaseOrCategoryContainingIgnoreCaseOrManufacturerContainingIgnoreCaseOrInformationValueContainingIgnoreCase(String name,String category, String manufacturer, String value);
}
Application :
#SpringBootApplication(scanBasePackages = {"Service", "repository", "controller"})
#EntityScan("DataModel")
#EnableJpaRepositories(basePackages = "repository")
public class CloudliquidApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(CloudliquidApplication.class, args);
System.out.println("Let's inspect the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
}
#Bean
public ProductService productService() {
return new ProductServiceImpl();
}
#Bean
public TomcatServletWebServerFactory tomcatFactory() {
return new TomcatServletWebServerFactory() {
#Override
protected void postProcessContext(Context context) {
((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
}
};
}

What do I need to do, so that Russian characters will finally begin to be perceived?
Before moving to the spring, it helped me - new String (source.getBytes (), StandardCharsets.UTF-8)). But after the move it stopped working (in any format).
What else should you try? If anything, I transfer the data from Android (Retrofit).

move String query from #RequestHeader to #RequestParam

You need to remove DataSourceAutoConfiguration.class from exclusions. That is what sets up the EntityManagerFactory.
So this:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
// Main class definition
Should be:
#SpringBootApplication()
// Main class definition

Can't find the request for URL's Observer

i'm building my first SOAP application using Spring Boot + Apache CXF and Maven.
I've followed this guide:
https://www.baeldung.com/apache-cxf-with-spring
Without using XML file, so at the end i have those classes:
DemoApplication
#SpringBootApplication
public class DemoApplication{
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
ServiceConfiguration
#Configuration
public class ServiceConfiguration {
#Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
ServletDestinationFactory destinationFactory = new ServletDestinationFactory();
SpringBus bus = new SpringBus();
bus.setExtension(destinationFactory, HttpDestinationFactory.class);
return bus;
}
#Bean
public Endpoint endpoint() {
EndpointImpl endpoint = new EndpointImpl(springBus(), new BaeldungImpl());
endpoint.publish("http://localhost:8080/demo-0.0.1-SNAPSHOT");
return endpoint;
}
}
AppInitializer
public class AppInitializer implements WebApplicationInitializer {
#Override
public void onStartup(ServletContext container) {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(ServiceConfiguration.class);
container.addListener(new ContextLoaderListener(context));
ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new CXFServlet());
dispatcher.addMapping("/services/*");
}
}
BaeldungImpl
#WebService(endpointInterface = "com.example.demo.Baeldung")
public class BaeldungImpl implements Baeldung {
private int counter;
#Override
public String hello(String name) {
return "Hello " + name + "!";
}
#Override
public String register(Student student) {
counter++;
return student.getName() + " is registered student number " + counter;
}
#Override
public String ProvaServizio() {
return "";
}
}
Baeldung
#WebService
public interface Baeldung {
public String hello(String name);
public String register(Student student);
public String ProvaServizio();
}
Student
public class Student {
private String name;
Student() {
}
public Student(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
After buildin and deploying on Tomcat, following this URL i reach this:
Available SOAP services:
If i try to go further (adding /hello,/hegister or /ProvaServizio) i've got this error:
No service was found.
And the log says:
15:48:19.416 [http-nio-8080-exec-127] WARN org.apache.cxf.transport.servlet.ServletController - Can't find the request for http://localhost:8080/demo-0.0.1-SNAPSHOT/services/hello's Observer

404 Not Found Spring Boot application using spring cloud starter security

I am currently following a Pluralsight tutorial about Java Microservices with Spring Cloud Security. After I run this application, I copy the generated security password from log and in Postman i am calling
http://localhost:9001/services/tolldata using Basic Auth with user: user and password: the generated one. But it gives as response 404 Not Found.
I have tried to change port from application settings, the same result.
Tried to add also the host address in properties, the same result.
Deleted the server.servlet.context-path, same result.
Placed the #RequestMapping("/tolldata") above the getTollData() method, same result.
This is my main class.
#SpringBootApplication
#RestController
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#RequestMapping("/tolldata")
public class TollUsage{
public String id;
public String stationId;
public String licensePlate;
public String timestamp;
public List<TollUsage> getTollData(){
TollUsage instance1 = new TollUsage("100", "station150", "B65GT1W", "2016-09-30T06:31:22");
TollUsage instance2 = new TollUsage("101", "station119", "AHY673B", "2016-09-30T06:32:50");
TollUsage instance3 = new TollUsage("102", "station150", "ZN2GP0", "2016-09-30T06:37:01");
List<TollUsage> tolls = new ArrayList<TollUsage>();
tolls.add(instance1);
tolls.add(instance2);
tolls.add(instance3);
return tolls;
}
public TollUsage(){}
public TollUsage(String id, String stationId, String licensePlate, String timestamp){
this.id = id;
this.stationId = stationId;
this.licensePlate = licensePlate;
this.timestamp = timestamp;
}
}
}
This is my application.properties
server.port=9001
server.servlet.context-path=/services

Put #RestController on your TollUsage class, not DemoApplication and split these classes to diffrent files.
Try this:
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
#RequestMapping(value = "/tolldata")
#RestController
class TollUsage{
public String id;
public String stationId;
public String licensePlate;
public String timestamp;
#GetMapping
#CrossOrigin
#ResponseBody
public ResponseEntity<List<TollUsage>> getTollData(){
TollUsage instance1 = new TollUsage("100", "station150", "B65GT1W", "2016-09-30T06:31:22");
TollUsage instance2 = new TollUsage("101", "station119", "AHY673B", "2016-09-30T06:32:50");
TollUsage instance3 = new TollUsage("102", "station150", "ZN2GP0", "2016-09-30T06:37:01");
List<TollUsage> tolls = new ArrayList<TollUsage>();
tolls.add(instance1);
tolls.add(instance2);
tolls.add(instance3);
return new ResponseEntity<>(tolls, HttpStatus.OK);;
}
public TollUsage(){}
public TollUsage(String id, String stationId, String licensePlate, String timestamp){
this.id = id;
this.stationId = stationId;
this.licensePlate = licensePlate;
this.timestamp = timestamp;
}
}
