Convert entity property camel case to snake case in json in jhipster project

You have two possibilities:

Explicit naming your properties:

@JsonProperty("name_bangla")private String nameBangla;@JsonProperty("name_english")private String nameEnglish;

or changing how jackson (which is used for de/serialization) works:

Jackson has a setting called PropertyNamingStrategy.SNAKE_CASE which you can set for the jackson objectmapper.

So, you need to configure Jackson for that, e.g. by adding your own object mapper:

@Configurationpublic class JacksonConfiguration {    @Bean    public Jackson2ObjectMapperBuilder jackson2ObjectMapperBuilder() {        return new Jackson2ObjectMapperBuilder().propertyNamingStrategy(PropertyNamingStrategy.SNAKE_CASE)    }} 

As far as I know, in older version of JHipster, there was already a JacksonConfiguration to configure the JSR310 time module, but was removed later...

Adding this to your application.yml should also work:

spring.jackson.property-naming-strategy=SNAKE_CASE

Also you can use annotation to define naming strategy per class.

Little example in Kotlin:

@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy::class)data class Specialization(val altUrl: String, val altId: Int, val altName: String)
