### 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](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version Dubbo Version: 3.3.1 Spring Boot Version: 3.2.3 Java Version: 21 ### Steps to reproduce this issue I am using Dubbo 3.3.1 integrating with Spring Boot 3. The Triple protocol is configured to use the Servlet container (sharing the port with Spring Boot). 1. Configuration (application.yml): server: port: 8083 dubbo: protocol: name: tri port: ${server.port} triple: servlet: enabled: true registry: address: zookeeper://${zookeeper.address:127.0.0.1}:2181 2.Service Implementation: @Path("/demo") @DubboService public class DemoServiceImpl implements DemoService { @Override @POST @Path("/user") public String getUserInfo(UserContext userContext) { // Issue: userContext is not null, but userId/userName are sometimes null System.out.println("userContext: " + userContext.toString()); return "success"; } } 3.POJO (UserContext): public class UserContext { private String userId; private String userName; public UserContext(String userId, String userName) { this.userId = userId; this.userName = userName; } // getters and setters... } 5.build.gradle dependencies { implementation(platform("org.apache.dubbo:dubbo-bom:3.3.1")) implementation("org.springframework.boot:spring-boot-starter-web") implementation("org.apache.dubbo:dubbo-spring-boot-starter") implementation("org.apache.dubbo:dubbo-zookeeper-spring-boot-starter") implementation("org.apache.dubbo:dubbo-spring-boot-3-autoconfigure") implementation 'org.apache.dubbo:dubbo-rpc-triple:3.3.1' implementation("jakarta.ws.rs:jakarta.ws.rs-api:3.1.0") } 4.Client Request: Send a POST request to http://localhost:8083/demo/user with JSON body {"userId":"1", "userName":"test"} repeatedly. Actual Behavior When sending the same request multiple times, the behavior is inconsistent: Sometimes (Success): The userContext is correctly populated: UserContext{userId='1', userName='test'}. Sometimes (Failure): The userContext object is instantiated, but all properties are null: UserContext{userId='null', userName='null'}. ### What you expected to happen The UserContext should always be correctly populated with the values from the JSON request body. ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [ ] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
