How to format the json date format using spring bo

问题:

I am working on spring boot and gradle for creating a rest service. Now I need to format the json date in the form of "yyyy-MM-dd", i.e, the format should be dateOfBirth: "16-03-2015", but I am getting "dateOfBirth: -751181400000". I added the below piece of code in my Apllication.java class, but still not able to get the desired output.

@Bean
@ConditionalOnClass({ ObjectMapper.class, Jackson2ObjectMapperBuilder.class })
public Jackson2ObjectMapperBuilder jacksonBuilder()
{ 
    Jackson2ObjectMapperBuilder builder = new Jackson2ObjectMapperBuilder(); 
    builder.indentOutput(true).dateFormat(new SimpleDateFormat("yyyy-MM-dd")); 
    return builder; 
}

And Application.java:

@Configuration
@Import(SubjectServiceConfig.class)
@EnableAutoConfiguration
@EnableEurekaClient
@ComponentScan({"com.billing"})
@EnableWebMvc
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
public class Application {
public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}
}

Kindly help me out in resolving this issue.

With Spring Boot, you should be able to set the default way that Jackson formats dates by setting the following property in your application.yml/application.properties:

spring.jackson.date-format= # Date format string (e.g. yyyy-MM-dd HH:mm:ss), or a fully-qualified date format class name (e.g. com.fasterxml.jackson.databind.util.ISO8601DateFormat)
