如何在Roo中添加Timestamp到Spring-Data-Mongo？

Question

我有一个Spring Roo的项目，我想基于log4mongo的Java附加器来创建和我想访问，看起来像数据项：

{ 
"_id" : ObjectId("4f16cd30b138685057c8ebcb"), 
"timestamp" : ISODate("2012-01-18T13:46:24.704Z"), 
"level" : "INFO", "thread" : "catalina-exec-8180-3", 
"message" : "method execution[execution(TerminationComponent.terminateCall(..))]", 
"loggerName" : 
    { "fullyQualifiedClassName" : "component_logger", 
    "package" : ["component_logger"], 
    "className" : "component_logger" 
    }, 
"properties" : { 
    "cookieId" : "EDE44DC03EB65D91657885A34C80595E" 
}, 
"fileName" : "LoggingAspect.java", 
"method" : "logForComponent", 
"lineNumber" : "81", "class" : { 
    "fullyQualifiedClassName" : "com.comcast.ivr.core.aspects.LoggingAspect", 
    "package" : ["com", "comcast", "ivr", "core", "aspects", "LoggingAspect"], 
    "className" : "LoggingAspect" 
}, 
"host" : { 
    "process" : "2220@pacdcivrqaapp01", 
    "name" : "pacdcivrqaapp01", 
    "ip" : "24.40.31.85" 
}, 
"applicationName" : "D2", 
"eventType" : "Development" 
} 

时间戳的样子：

"timestamp" : ISODate("2012-01-17T22:30:19.839Z") 

如何在我的日志记录域对象中添加一个字段来映射此字段？

这只是JavaScript Date（根据mongo docs，可能是demonstrated in the shell），所以请尝试java.util.Date。
