Message Broker 6.1睡眠異常

Question

我試圖添加一個簡單的sleep函數來擴展基本的ESQL API。

Java實現：

public static void sleep(long millis) { 
    try { 
     Thread.sleep(millis); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 
} 

ESQL參考：

CREATE PROCEDURE sleep(IN millis INT) 
    LANGUAGE JAVA 
    EXTERNAL NAME "com.mypackage.Util.sleep"; 

這是錯誤跟蹤：

(0x01000000:Name ):RecoverableException = (
     (0x03000000:NameValue):File  = '/build/S610_P/src/DataFlowEngine/ImbRdl/ImbRdlExternalJava.cpp' (CHARACTER) 
     (0x03000000:NameValue):Line  = 1102 (INTEGER) 
     (0x03000000:NameValue):Function = 'ESQL2JavaMethodResolver::decodeReturnStatus' (CHARACTER) 
     (0x03000000:NameValue):Type  = '' (CHARACTER) 
     (0x03000000:NameValue):Name  = '' (CHARACTER) 
     (0x03000000:NameValue):Label = '' (CHARACTER) 
     (0x03000000:NameValue):Catalog = 'BIPv610' (CHARACTER) 
     (0x03000000:NameValue):Severity = 3 (INTEGER) 
     (0x03000000:NameValue):Number = 2946 (INTEGER) 
     (0x03000000:NameValue):Text  = 'The Java method could not be found' (CHARACTER) 
     (0x01000000:Name ):Insert = (
      (0x03000000:NameValue):Type = 5 (INTEGER) 
      (0x03000000:NameValue):Text = 'com.mypackage.Util.sleep' (CHARACTER) 
     ) 
    ) 
    ) 
) 
)

解決了！供將來參考：

問題出在想要包裝類型的方法簽名檢查。
在這種情況下，Long而不是long。

public static void sleep(Long millis) { 
    try { 
     Thread.sleep(millis); 
    } catch (InterruptedException e) { 
     e.printStackTrace(); 
    } 
}
