ont lan hand isp agg dispatch port dto web
1.DEBUG [2017-07-10 11:38:41,705][] org.springframework.web.servlet.DispatcherServlet:865 - DispatcherServlet with name ‘dispatcherServlet‘ processing POST request for [/profit/queryProfitAccountList]
註：spring mvc的的dispatcherservlet會日誌打印傳進來的每個請求的url和http方法，並日誌debug輸出打印
dispatcherservlet處理分發請求後，當然就要handlermapping查找controller的方法了，如下打印：2.DEBUG [2017-07-10 11:38:41,705][] org.springframework.web.servlet.handler.AbstractHandlerMethodMapping:310 - Looking up handler method for path /profit/queryProfitAccountList
debug打印“Looking up handler method for path /profit/queryProfitAccountList
3.DEBUG [2017-07-10 11:38:41,705][] org.springframework.web.servlet.handler.AbstractHandlerMethodMapping:317 - Returning handler method [public java.util.Map<java.lang.String, java.lang.Object> com.pingan.property.icore.pap.aggregation.profit.controller.ProfitController.queryProfitAccounts(com.pingan.property.icore.pap.aggregation.profit.dto.QueryProfitAccountReqDTO)]
handlermapping查找到url對應的controller和方法，並log打印出來controller類名和處理方法名，並打印出整個方法的形參和返回值
