Can Jackson converte a POGO to JSON in spring without @JSONProperty?

Question

How can jackson MappingJackson2HttpMessageConverter converte a pogo into a json without @JSONProperty ON every Property?

I use groovy in spring boot project and no java code, I hava a domain model named FileInfo.groovy:

class FileInfo {
    private String name

    @JsonProperty("is_dir")
    private boolean isDirectory

    @JsonProperty("last_modified")
    private String lastModifiedTime
}

I configured MappingJackson2HttpMessageConverter in @Configuration @EnableWebMvc class.

and when return a FileInfo in controller handler with @ResponseBody,THERE is no name in result json;

I know the pogo property is accessed by public void setProperty(java.lang.String, java.lang.Object);

So are there a annotation on class that can mark a pogo that can convert by jackson? cuz it is too noisy use @JSONProperty on every property.

See this question. The question shows how to set the visibility for a class and the accepted answer shows how to set the visibility for an entire ObjectMapper.

The idea is to set the field visibility to Visibility.ANY to pick up private fields.
