 UnsatisfiedDependencyException: Fehler beim Erstellen einer Bean mit dem Namen „HController“, verursacht durch NoSuchBea

Post by Anonymous »

Ich bin neu bei Spring und versuche, das CrudRepository von Spring zu verwenden. Ich erhalte eine NoSuchBeanDefinitionException-Ausnahme, wenn ich versuche, eine Klasse automatisch zu verbinden, die org.springframework.data.repository.CrudRepository implementiert. Ich habe meinen Fehler untersucht und sichergestellt, dass sich alle meine Dateien im selben Paket befinden, aber ich erhalte immer noch diesen Fehler und habe Schwierigkeiten, ihn zu lösen.

Hier ist der Controller:

Code: Select all

package com.H.spring.security.config.core;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HController {

@Autowired
private UserRepository userRepository;

@GetMapping(path="/add") // Map ONLY GET Requests
public @ResponseBody String addNewUser (@RequestParam String name
, @RequestParam String email) {
User n = new User();
n.setName(name);
n.setEmail(email);
userRepository.save(n);
return "Saved";
}

@GetMapping(path="/all")
public @ResponseBody Iterable getAllUsers() {
// This returns a JSON or XML with the users
return userRepository.findAll();
}

}
Hier ist das UserRepository:

Code: Select all

package com.H.spring.security.config.core;

import org.springframework.data.repository.CrudRepository;

public interface UserRepository extends CrudRepository {

}
Hier ist meine Anwendungskonfiguration:

Code: Select all

package com.H.spring.security.config.core;

@EnableWebMvc
@Configuration
@ComponentScan({ "com.H.spring.security.config.*" })
@Import(value = { HSecurityConfig.class })
public class HApplicationConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware{

private ApplicationContext applicationContext;

@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
}

@Bean
public ViewResolver viewResolver() {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine());
resolver.setCharacterEncoding("UTF-8");
return resolver;
}

@Bean
public TemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setEnableSpringELCompiler(true);
engine.setTemplateResolver(templateResolver());
return engine;
}

@Bean
public SpringTemplateEngine templateEngine1() {
SpringTemplateEngine templateEngine = new SpringTemplateEngine();
templateEngine.setTemplateResolver(templateResolver());
templateEngine.addDialect(new SpringSecurityDialect());
return templateEngine;
}

private ITemplateResolver templateResolver() {
SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
resolver.setApplicationContext(applicationContext);
resolver.setPrefix("/WEB-INF/templates/");
resolver.setTemplateMode(TemplateMode.HTML);
return resolver;
}

@Bean(name = "multipartResolver")
public MultipartResolver getMultipartResolver() {
CommonsMultipartResolver resover = new CommonsMultipartResolver();
resover.setMaxUploadSize(1024 * 1024 * 1024);
return resover;
}

@Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/").setCachePeriod(0);
}

}
Unten ist die Fehlermeldung aufgeführt, die ich erhalte:

UPDATE 1

Nachdem ich die @EnableJpaRepositories zu meiner Konfiguration hinzugefügt habe, erhalte ich die folgende Fehlermeldung:
