Time format (struts) in JSP __js

Today encountered a time format conversion of Dongdong, depressed half of the afternoon, but fortunately finally finished.
Originally wanted to take YYYY-MM-DD format, but how the whole is Greenwich mean.
Our project is to use the Struts framework, using Idv.getupdatetime (). toLocaleString () can get XXXX xx month xx days xx:xx:xx
Finally, it is found that the attribute definition in the IdV class is a date type, which results in Greenwich time when fetching data.
After you change the date type to a string type, you also modify all classes that use the IdV class method, because the control layer is the actual calling method, which is typically in the Factoryimpl or Bo class, Find a method to modify its properties. Use the Dateutil.millistosimpledatestring () method in the API to transform the data into the parameters of the set method to produce the YYYY-MM-DD format
It is important to note that in other classes it is not necessary to define the time attribute as a string or a date type, and the key is which time conversion method is used.
If your set method parameter is a date type, you can use as the parameter new date (Long.parselong ())
