Convert Bean to Query Parameter

In Spring Web/WebFlux (server side), it will automatically convert query parameters to Java Bean, but Spring Cloud OpenFeign and @HttpExchange does not support to convert Java bean to query parameters by default. In Spring Cloud OpenFeign you need @SpringQueryMap to achieve this feature.

httpexhange-spring-boot-starter supports this feature, and you don't need any additional annotations.

info

In order not to change the default behavior of Spring, this feature is disabled by default, you can set http-exchange.bean-to-query-enabled=true to enable it.

public interface PostApi {
  @GetExchange("/posts")
  List<Post> findAll(Post condition);
}

Auto convert non-null value type fields of condition to query parameters. Such as primitive/wrapper types, String, etc.

If you don't want to enable this feature globally, you can use @BeanParam, it is an equivalent replacement for @SpringQueryMap.

tip

The @BeanParam annotation's naming is inspired by JAX-RS.
