刚开始用 spring mvc 做 web 开发时,经常会不知道如何合适绑定页面数据.用惯 struts2 的朋
友更认为 spring mvc 绑定数据不如 struts2 方便(本人最开始也是这么认为),经过一段时间
的应用和测试,总结出以下几种情况,希望对刚接触 spring mvc 的朋友有所帮助.
示例程序下载
查看 spring 源码可以看出 spring 支持转换的数据类型已经很多了.
org.springframework.beans.PropertyEditorRegistrySupport.java
[java]view plaincopy
1. /**
2. *Actuallyregisterthedefaulteditorsforthisregistryinstanc
e.
3. */
4. privatevoiddoRegisterDefaultEditors(){
5. this.defaultEditors=newHashMap<Class,PropertyEditor>(64);
6. //Simpleeditors,withoutparameterizationcapabilities.
7. //TheJDKdoesnotcontainadefaulteditorforanyofthese
targettypes.
8. this.defaultEditors.put(Charset.class,newCharsetEditor());
9. this.defaultEditors.put(Class.class,newClassEditor());
10. this.defaultEditors.put(Class[].class,newClassArrayEditor())
;
11. this.defaultEditors.put(Currency.class,newCurrencyEditor());
12. this.defaultEditors.put(File.class,newFileEditor());
13. this.defaultEditors.put(InputStream.class,newInputStreamEdit
or());
14. this.defaultEditors.put(Locale.class,newLocaleEditor());
15. this.defaultEditors.put(Pattern.class,newPatternEditor());
16. this.defaultEditors.put(Properties.class,newPropertiesEditor
());
