Question

spring boot的新功能，如果问题不清楚，请您谅解！我收到以下错误：

申请无法开始

说明：

com.modern.services.UserService中的字段userConv需要一个类型为'com.modern.converter.UserConverter'的bean。

操作：

考虑在您的配置中定义类型为'com.modern.converter.UserConverter'的bean。

    package com.modern;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;



@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan 
@Configuration

public class SpringBootAngular4Application{


    public static void main(String[] args) {
        SpringApplication.run(SpringBootAngular4Application.class, args);
    }
}

UserConverter

    package com.modern.converter;

import java.util.ArrayList;
import java.util.List;
import com.modern.module.User;
import com.modern.viewmodels.UserViewModel;


public class UserConverter implements IModelViewModelConverter < User , UserViewModel > {      

    @Override 
    public User fromViewModel ( UserViewModel vm ) { return null; }

    @Override 
    public List < User > fromViewModelList ( List < UserViewModel > vmList ) { return null ; }

    @Override 
    public UserViewModel toViewModel ( User m ) { 

        UserViewModel uvm = new UserViewModel();

        uvm.setFirstname ( m.getFirstname ()); 
        uvm.setLastname ( m.getLastname ()); 
        uvm.setCountry ( m.getCountry ()); 
        uvm.setAge ( m.getAge ());
        return uvm ; 

        }

     @Override 
     public List < UserViewModel > toViewModelList ( List < User > mList ) 
     {
         List < UserViewModel > users = new ArrayList <> (); for ( User u : mList ) 
             users . add ( this . toViewModel ( u ));  
         return users ; 
         }

}
