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] 
注：spring mvc的的dispatcherservlet会日志打印传进来的每个请求的url和http方法，并日志debug输出打印

dispatcherservlet处理分发请求后，当然就要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对应的controller和方法，并log打印出来controller类名和处理方法名，并打印出整个方法的形参和返回值
