Make JSON payload fields case insensitive when mapping to Java Object in REST API developed using SpringBoot

Question

I am working on REST API developed using SpringBoot application. Here I want to make the fields in the payload(JSON) as case insensitive when mapping to a Java Object. Below

Answer 1

I recently found a solution via Annotation config:

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.fasterxml.jackson.databind.MapperFeature;
import com.fasterxml.jackson.databind.ObjectMapper;

@Configuration
public class Config {

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper mapper = new ObjectMapper();
        mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
        return mapper;
    }

}

I'm using these dependencies:

    org.springframework.boot
    spring-boot-starter-parent
    1.3.3.RELEASE


    
        org.springframework.boot
        spring-boot-starter-thymeleaf
    

    
        org.springframework.boot
        spring-boot-starter-web
    

    
        org.springframework
        spring-core
    

    
        com.fasterxml.jackson.module
        jackson-module-jaxb-annotations
        2.6.5
    

Good luck.
