 Unzufriedene Abhängigkeitsexception: Fehler beim Erstellen von Bean mit dem Namen 'HController' durch NoSuchbeandefiniti

Post by Anonymous »

Ich bin neu im Frühling und versuche, Spring's Crudrepository zu verwenden. Ich erhalte eine NoSuchbeandeFinitionException Ausnahme, wenn ich versuche, eine Klasse zu verdrahten, die org.springframework.data.repository.crudrepository implementiert. Ich habe meinen Fehler untersucht und dafür gesorgt, dass alle meine Dateien unter demselben Paket waren, aber ich erhalte diesen Fehler und habe Schwierigkeiten, ihn zu lösen.

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();
}

}
< /code>

Hier ist das userrepository: < /p>

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

import org.springframework.data.repository.CrudRepository;

public interface UserRepository extends CrudRepository {

}
< /code>

Hier ist meine Anwendungskonfiguration: < /p>

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);
}

}
< /code>

Unten ist der Fehler, den ich empfange: < /p>

Nach dem Hinzufügen der @EnableJParePosition zu meiner Konfiguration erhalte ich den folgenden Fehler: < /p>
