Method Detail

rootTrace

@CozeTrace
public void rootTrace(org.springframework.context.ConfigurableApplicationContext context)

Basic usage: Automatically captures method name as span name.

simpleTrace

@CozeTrace
public void simpleTrace(String input)

Basic usage: Automatically captures method name as span name.

customTrace

@CozeTrace(name="llm_chat_v1",
           spanType="model",
           captureArgs=true,
           captureReturn=true)
public String customTrace(String model,
                                                                                                                                                  String query)

Customization: Specify span name, type, and capture input/output.

spelTrace

@CozeTrace(name="operation_#{#arg0}",
           spanType="business",
           inputExpression="#arg1",
           outputExpression="#result")
public Map<String,Object> spelTrace(String action,
                                                                                                                                                                                     Map<String,Object> params)

Advanced usage: Use SpEL expressions for dynamic span names and precise data extraction. #arg0, #arg1 refers to method arguments. #args[n] also works.

errorTrace

@CozeTrace(name="unstable_operation")
public void errorTrace()

Error handling: The aspect automatically captures exceptions and records them as span errors.
