sping boot returns the JSON format definition

During the writing of the project, an issue was encountered that needed to define the format of the returned JSON field

For example, in an entity attribute, I have a field that is username, so the need to appear in JSON is user_name, that is, using the underscore name method

You can then use @JsonProperty this annotation to customize the @JsonProperty ("user_name")

But if all my attributes are to be used in this way, do I add one by one?

In fact, just define Jackson's property naming policy to add

(yml format)

Spring

Jackson

Property-naming-strategy:snake_case

(propreties format)

Spring.jackson.property-naming-strategy=snake_case

You can do it.

All policies are

Strategy	Example	Note
Lower_camel_case	UserName	Default Policy
Kebab_case	User-name
Lower_case	Username
Snake_case	User_name
Upper_camel_case	UserName

There seems to be no problem here, but if I have only one entity, the attribute name needs to be mapped to one of the above conditions,

But there are many attribute names, too lazy to add it?

In fact, there are methods, as long as the need to add the entity@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy.class)这样的注解就可以了

The strategies you can use here are also consistent with those in the table above

Above
