In the core application context like AnnotationConfigApplicationContext, Spring doesn't have any mechanism or hook on the client code to configure ConversionService instance as it does in spring MVC environment. In Core application context environment if we want to use it on client code then we have to inject it as a normal bean and apply the conversion manually by calling ConversionService#convert() method.
Example
package com.logicbig.example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.convert.ConversionService;
import java.util.List;
public class ClientBean {
@Autowired
private ConversionService conversionService;
public void showAsList(String listAsString) {
List<String> list = conversionService.convert(listAsString, List.class);
list.forEach(System.out::println);
}
}
package com.logicbig.example;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.ConversionService;
import org.springframework.core.convert.support.DefaultConversionService;
@Configuration
public class AppConfig {
@Bean
public ConversionService conversionService() {
return new DefaultConversionService();
}
@Bean
public ClientBean clientBean() {
return new ClientBean();
}
}
package com.logicbig.example;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
public class ExampleMain {
public static void main(String[] args) {
AnnotationConfigApplicationContext context = new
AnnotationConfigApplicationContext(AppConfig.class);
ClientBean clientBean = context.getBean(ClientBean.class);
clientBean.showAsList("one, two, three");
}
}
Output
one two three
