Servlet çağrısı başarısız. Spring rest

Question

kullanma requestMapping ek açıklama kullanarak bir servlet çağırmaya çalışıyorum. Sunucuda çalışan bir index.html sayfası var. Ancak, http://localhost:8080/spring-rest/api/users yazarak bir sunucuya başvurduğumda çalışmaz. Projemde 5 tane dersim var. İşte kod.

User.java

package io.egen.entity; 

import lombok.Data; 

@Data 
public class User { 


    public User(String id, String firstName, String lastName, String email, String compnay) { 
     super(); 
     this.id = id; 
     this.firstName = firstName; 
     this.lastName = lastName; 
     this.email = email; 
     this.compnay = compnay; 
    } 
    private String id; 
    private String firstName; 
    private String lastName; 
    private String email; 
    private String compnay; 
} 

UserController.java

package io.egen.controller; 

import java.util.List; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.http.MediaType; 
import org.springframework.web.bind.annotation.RequestMapping; 
import org.springframework.web.bind.annotation.RequestMethod; 
import org.springframework.web.bind.annotation.RestController; 

import io.egen.entity.User; 
import io.egen.services.UserService; 

@RestController 
@RequestMapping(value="/users") 
public class UserController { 

    @Autowired 
    private UserService services; 

    @RequestMapping(method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_UTF8_VALUE) 
    public List<User> findAll() { 
     return services.findAll(); 
    } 

} 

UserService.java

package io.egen.services; 

import java.util.ArrayList; 
import java.util.List; 
import java.util.UUID; 

import org.springframework.stereotype.Service; 

import io.egen.entity.User; 

@Service 
public class UserService { 

    public List<User> findAll() { 
     System.out.println("Inside UserService"); 
     List<User> users = new ArrayList<User>(); 
     users.add(new User(UUID.randomUUID().toString(), "Praveen1", "Salitra", "psalitra1@egen.io", "Egen Solutions")); 
     users.add(new User(UUID.randomUUID().toString(), "Praveen2", "Salitra", "psalitra2@egen.io", "Egen Solutions")); 
     users.add(new User(UUID.randomUUID().toString(), "Praveen3", "Salitra", "psalitra3@egen.io", "Egen Solutions")); 
     return users; 
    } 
} 

AppInitializer.java

package io.egen; 

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer; 

public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

    @Override 
    protected Class<?>[] getRootConfigClasses() { 
     return new Class [] {AppConfig.class}; 
    } 

    @Override 
    protected Class<?>[] getServletConfigClasses() { 
     return null; 
    } 

    @Override 
    protected String[] getServletMappings() { 
     System.out.println("HEy"); 
     return new String [] {"/api/*"}; 
    } 


} 

AppConfig.java

package io.egen; 

import org.springframework.context.annotation.ComponentScan; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.servlet.config.annotation.EnableWebMvc; 

@Configuration 
@ComponentScan 
@EnableWebMvc 
public class AppConfig { 

} 

ben sırayla USerService.java içinde findAll yöntemini çağıran UserController.java içinde findAll yöntemini çağırmak çalışıyorum

Here is my package structure

pom.xml . Ancak AppInitializer.java'daki getservletMappings yönteminin çalışmadığını düşünüyorum. Bana yardımcı olun.

Teşekkürler!

Answer 1

Kuralların bir kaç sorunları görmek:

@ComponentScan({"io.egen.controller", "..."})

Kişisel kontrolör /users eşleştirilmiş: böylece açıkça paketleri söz gibi

1. Muhtemelen ComponentScan ek açıklama değiştirmelisiniz ama sizin AppInitializer sadece /api/* için eşleştirmeleri yapılandırıyor, böylece denetleyiciniz Spring'intarafından işlenmeyecek.
