第一種用法：引用org.apache.commons.logging.Log。

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

private static final Log logger = LogFactory.getLog(PolicyAppBizAction.class);  //PolicyAppBizAction.class是自己定義的當前類名。

logger.info("=======================calc start======================");

logger.debug("傳遞過來的參數 => " + param);
logger.debug("submitToUnderwriting:參數 => " + serviceRequest.getCUST_DATA());

catch (Exception e) {
      logger.error("團單險別VO屬性拷貝異常. PolicyAppBizAction.procGroupCvrg()");
      throw new BusinessServiceException(e);
 }

第二種用法：調用log4j。
import org.apache.log4j.Logger;
private Logger logger = Logger.getLogger(this.getClass()); //this.getClass()指當前的類。
public Logger getLogger() {
        return this.logger;
    }

    public void setLogger(Logger logger) {
        this.logger = logger;
    }
this.logger.info("==============調用平臺接口投保預確認出錯========================");
