Pre-check

[x] I am sure that all the content I provide is in English.

Search before asking

[x] I had searched in the issues and found no similar issues.

Apache Dubbo Component

Java SPI Extensions (apache/dubbo-spi-extensions)

Dubbo Version

Dubbo Java 3.3.0 oracle jdk 17

Steps to reproduce this issue

my rest api ```java @PostMapping("addUser") public R addUser(@RequestBody UserParam user) { return R.ok(user); }


2. my dubbo interface
```java
    @PostMapping(value = "addUser", consumes = MediaType.APPLICATION_JSON_VALUE)
    R<UserParam> addUser(@RequestBody UserParam user);

FormConsumerParamParser parses parameters after BodyConsumerParamParser in the resolution order.

Finally, JsonUtils.toJson produced an incorrect request body.

What you expected to happen

FormConsumerParamParser should not support @RequestBody

@Godfunc The BodyConsumerParamParser you mentioned should be part of the old REST protocol used before version 3.2.0. It is recommended to upgrade to the latest Triple REST after version 3.3.0 https://dubbo.apache.org/zh-cn/overview/mannual/java-sdk/tasks/protocols/rest/

@oxsean My provider is a REST API that does not use the Dubbo framework. I'm trying to use org.apache.dubbo.extensions:dubbo-rpc-rest to call the provider's REST endpoints. Since Triple REST requires the provider to integrate the Dubbo framework, it doesn't suit my use case, so dubbo-rpc-rest seems to be my only option.

However, FormConsumerParamParser supports parameters annotated with @RequestBody, which causes it to process the request parameters and ultimately results in an incorrect request JSON.

public enum ParamType {
    FORM(addSupportTypes(
            JAXRSClassConstants.FORM_PARAM_ANNOTATION_CLASS,
            JAXRSClassConstants.FORM_BODY_ANNOTATION_CLASS,
            SpringMvcClassConstants.REQUEST_BODY_ANNOTATION_CLASS)), // replace with REQUEST_PARAM_ANNOTATION_CLASS
...
}
