Initialization parameter bindings for SPRINGMVC

Initialize parameter bindings: Date format

A: First we do a date format binding, configuration initialization parameter binding and custom type conversion have the same wonderful

The configuration steps are as follows:

1. We first configure the Applicationcontext.xml for scanner configuration

　

2. Next we define its processor, and the binding of the method (@InitBinder)

3. Test in a single date format:

<form action= "${pagecontext.request.contextpath}/first.do" method= "POST" >   
Two: multiple date formats
1. First we need to inherit an editor (Propertieseditor)
Rewrite it's Setastext method
So that subsequent assignments to the Date object
public class Mydateeditor extends propertieseditor{    @Override public    void Setastext (String source) throws illegalargumentexception {      SimpleDateFormat sdf=getdate (source);      try {setValue (Sdf.parseobject (source)),      } catch (ParseException e) {e.printstacktrace ();      }         } Private SimpleDateFormat getDate (String source) {SimpleDateFormat sdf=null;if (pattern.matches ("^\\d{4}-\\d{2}-\\d{2 }$ ", source)) {sdf=new SimpleDateFormat (" Yyyy-mm-dd ");} else if (pattern.matches ("^\\d{4}/\\d{2}/\\d{2}$", source)) {sdf=new SimpleDateFormat ("Yyyy/mm/dd");} else if (pattern.matches ("^\\d{4}\\d{2}\\d{2}$", source)) {sdf=new SimpleDateFormat ("YyyyMMdd");} else {throw new Typemismatchexception ("", Date.class);} return SDF;}}
2. Configuring the Processor
3. Perform a variety of date format tests:
Now belongs to your own not always belong to you, initialization parameters will also change with the binding.
