Spring common interfaces and classes (iii)

First, Customeditorconfigurer class

Customeditorconfigurer can read the class that implements the Java.beans.PropertyEditor interface and convert the string to the specified type. It is more convenient to use PropertyEditorSupport. PropertyEditorSupport implements the PropertyEditor interface, the Setastext must be redefined.

 Public classHello {PrivateString message; Privateuser User;  PublicString getMessage () {returnmessage; }     Public voidsetmessage (String message) { This. Message =message; }     PublicUser GetUser () {returnuser; }     Public voidsetUser (user user) { This. user =user; }}

The

    custom Property editor inherits the PropertyEditorSupport class, overriding the Setastext method.

 public  class  usereditor extends   propertyeditorsupport{@Override  public  void  setastext (String text)   IllegalArgumentException { //
      string[] arr = Text.split ("," );                Integer Age  = new  Integer (arr[1 = new   user ();        User.setname (arr[ 0
