scala sorg.slf4j.{Logger, Logger

错误
logger.warn("table为null,actionType:{},original:{}",actionType,value.getOriginal)

Error:(70, 14) ambiguous reference to overloaded definition,
both method warn in trait Logger of type (x$1: String, x$2: Any, x$3: Any)Unit
and  method warn in trait Logger of type (x$1: String, x$2: Object*)Unit
match argument types (String,String,String)
      logger.warn("table为null,actionType:{},original:{}",actionType,value.getOriginal)

正确：
logger.warn("table为null,actionType:{},original:{}",Array(actionType,value.getOriginal):_*)

slf4j 正确的日志打印异常堆栈的方式

@Test
public void testError() {
    String s = null;
    try {
        s.length();
    } catch (Exception e) {
        log.error(s, e);
        //当然如果你懒得想提示信息的话，直接这样log.error("", e);
    }
}
