我想要使用自定義佈局類進行玩框架2.0的logback日誌記錄。玩框架logback自定義佈局
首先，我定義的包utils的自定義佈局類：
package utils;
public class MonitorLayoutForLogback extends LayoutBase<ILoggingEvent> {
...
}
在我的conf/logging.xml文件，我把：
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="utils.MonitorLayoutForLogback">
<param name="programName" value="uowVisualizer" />
<param name="serviceGroup" value="shared" />
<param name="serviceIdentifier" value="uowVisualizer" />
</layout>
</encoder>
</appender>
但是當我戲中運行，如，
play run
我看到：
14:20:18,387 |-ERROR in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Could not create component [layout] of type [utils.MonitorLayoutForLogback] java.lang.ClassNotFoundException: utils.M

因此，play找不到我創建的佈局類。如何將佈局類放在類路徑上？
請注意，我也嘗試過通過分期項目，
play clean compile stage
，然後通過
target/start
開工的項目開始從封裝版本的項目，我沒有看到上述失蹤類錯誤。然而，我也從來沒有看到任何輸出，我甚至沒有看到建造的類。我添加了System.out.println語句每個構造該類如下，以驗證是否被正在興建類：
public MonitorLayoutForLogback() {
System.out.println("MonitorLayoutForLogback Constructor without arguments");
}
public MonitorLayoutForLogback(String program) {
System.out.println("MonitorLayoutForLogback Constructor with program "+program);
_program = program;
}
public MonitorLayoutForLogback(String program, String sGroup, String sid) {
System.out.println("MonitorLayoutForLogback Constructor with program "+program+" sGroup "+sGroup+" sid "+sid);
_program = program;
MonitoringInfo.setServiceGroup(sGroup);
MonitoringInfo.setServiceIdentifier(sid);
}
我到的logback配置的新手，所以我相信我錯過了一些明顯的東西。謝謝您的幫助。
