* 如何定义属性编辑器？

* 继承PropertyEditorSupport类，覆写setAsText()方法，参见：UtilDatePropertyEditor.java

* 将属性编辑器注册到spring中，参见：applicationContext-editor.xml

1. publicclassUtilDatePropertyEditorextendsPropertyEditorSupport
2. {
3. privateStringformat="yyyy-MM-dd";
4. publicvoidsetFormat(Stringformat)
5. {
6. this.format=format;
7. }
8. @Override
9. publicvoidsetAsText(Stringtext)throwsIllegalArgumentException
10. {
11. System.out.println("-------------text--------:"+text);
12. SimpleDateFormatsdf=newSimpleDateFormat(format);
13. try
14. {
15. Dated=(Date)sdf.parse(text);
16. this.setValue(d);
17. }
18. catch(ParseExceptione)
19. {
20. e.printStackTrace();
21. }
22. }
23. }
