英文:
BaggageField value returns null after update
问题
以下是您提供的内容的中文翻译：
我有以下的Spring Cloud Sleuth配置：
application.yml 文件：
sleuth:
baggage:
remote-fields: userId
correlation-fields: userId
配置类：
@Configuration
public class SleuthConfiguration {
@Bean
public BaggageField userIdBaggageField() {
return BaggageField.create("userId");
}
@Bean
public CurrentTraceContext.ScopeDecorator mdcScopeDecorator() {
return MDCScopeDecorator.newBuilder()
.clear()
.add(CorrelationScopeConfig.SingleCorrelationField
.newBuilder(userIdBaggageField())
.flushOnUpdate()
.build())
.build();
}
}
当在控制器中更新BaggageField时，getValue() 方法始终返回 null，尽管我配置了相应的BaggageField以在更新时刷新（.flushOnupdate() 文档）：
@RestController
@Slf4j
static class SampleController {
private final BaggageField userIdBaggageField;
SampleController(BaggageField userIdBaggageField) {
this.userIdBaggageField = userIdBaggageField;
}
@GetMapping("/sample")
public void periodes(@RequestParam String userId) {
log.info("设置BaggageField为 {}", userId);
this.userIdBaggageField.updateValue(userId);
log.info("BaggageField的值为 {}", this.userIdBaggageField.getValue());
}
}
日志：
设置BaggageField为 1234
BaggageField的值为 null
我可能错过了什么？谢谢。

.newBuilder(userIdBaggageField())
.flushOnUpdate()

.build();
}
}
When updating the BaggageField in the controller, the getValue() method always returns null, although I configured the corresponding BaggageField to flush on update (.flushOnupdate() documentation):
@RestController
@Slf4j
static class SampleController {
private final BaggageField userIdBaggageField;
SampleController(BaggageField userIdBaggageField) {
this.userIdBaggageField = userIdBaggageField;
}
@GetMapping("/sample")
public void periodes(@RequestParam String userId) {
log.info("Setting BaggageField to {}", userId);
this.userIdBaggageField.updateValue(userId);
log.info("BaggageField value {}", this.userIdBaggageField.getValue());
}
}
Logs:
Setting BaggageField to 1234
BaggageField value null
What did I possibly miss?
Thanks.

问题是由于配置的自定义传播器干扰默认的行李传播而引起的。
移除它会修复这个问题。
英文:
The issue was due to a configured custom propagator interfering with default baggage propagation.
Removing it fixes this issue.
