自定义springMVC的属性编辑器主要有两种方式,一种是使用@InitBinder标签在运行期注册一个属性编辑器,这种编辑器只在当前Controller里面有效;还有一种是实现自己的 WebBindingInitializer,然后定义一个AnnotationMethodHandlerAdapter的bean,在此bean里面进行注册 ,这种属性编辑器是全局的。
第一种方式:
- import java.beans.PropertyEditorSupport;
 - import java.io.IOException;
 - import java.text.SimpleDateFormat;
 - import java.util.Date;
 - import javax.servlet.http.HttpServletResponse;
 - import org.springframework.beans.propertyeditors.CustomDateEditor;
 - import org.springframework.stereotype.Controller;
 - import org.springframework.web.bind.WebDataBinder;
 - import org.springframework.web.bind.annotation.InitBinder;
 - import org.springframework.web.bind.annotation.PathVariable;
 - import org.springframework.web.bind.annotation.RequestMapping;
 - @Controller
 - public class GlobalController {
 - @RequestMapping("test/{date}")
 - public void test(@PathVariable Date date, HttpServletResponse response) throws IOException
 - response.getWriter().write( date);
 - }
 - @InitBinder//必须有一个参数WebDataBinder
 - public void initBinder(WebDataBinder binder) {
 - binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), false));
 - binder.registerCustomEditor(int.class, new PropertyEditorSupport() {
 - @Override
 - public String getAsText() {
 - // TODO Auto-generated method stub
 - return getValue().toString();
 - }
 - @Override
 - public void setAsText(String text) throws IllegalArgumentException {
 - // TODO Auto-generated method stub
 - System.out.println(text + "...........................................");
 - setValue(Integer.parseInt(text));
 - }
 - });
 - }
 - }
 
这种方式这样写了就可以了
第二种:
1.定义自己的WebBindingInitializer
- package com.xxx.blog.util;
 - import java.util.Date;
 - import java.text.SimpleDateFormat;
 - import org.springframework.beans.propertyeditors.CustomDateEditor;
 - import org.springframework.web.bind.WebDataBinder;
 - import org.springframework.web.bind.support.WebBindingInitializer;
 - import org.springframework.web.context.request.WebRequest;
 - public class MyWebBindingInitializer implements WebBindingInitializer {
 - @Override
 - public void initBinder(WebDataBinder binder, WebRequest request) {
 - // TODO Auto-generated method stub
 - binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), false));
 - }
 - }
 
2.在springMVC的配置文件里面定义一个AnnotationMethodHandlerAdapter,并设置其WebBindingInitializer属性为我们自己定义的WebBindingInitializer对象
- <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
 - <property name="cacheSeconds" value="0"/>
 - <property name="webBindingInitializer">
 - <bean class="com.xxx.blog.util.MyWebBindingInitializer"/>
 - </property>
 - </bean>
 
第二种方式经过上面两步就可以定义一个全局的属性编辑器了。
注意:当使用了<mvc:annotation-driven />的时候,它 会自动注册DefaultAnnotationHandlerMapping与AnnotationMethodHandlerAdapter 两个bean。这时候第二种方式指定的全局属性编辑器就不会起作用了,解决办法就是手动的添加上述bean,并把它们加在<mvc:annotation-driven/>的前面。
