SpringMVC中利用@InitBinder来对页面数据进行解析绑定的方法

public class BaseController {  @InitBinder  protected void initBinder(WebDataBinder binder) {    binder.registerCustomEditor(Date.class, new MyDateEditor());    binder.registerCustomEditor(Double.class, new DoubleEditor());     binder.registerCustomEditor(Integer.class, new IntegerEditor());  }  private class MyDateEditor extends PropertyEditorSupport {    @Override    public void setAsText(String text) throws IllegalArgumentException {      SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");      Date date = null;      try {        date = format.parse(text);      } catch (ParseException e) {        format = new SimpleDateFormat("yyyy-MM-dd");        try {          date = format.parse(text);        } catch (ParseException e1) {        }      }      setValue(date);    }  }    public class DoubleEditor extends PropertiesEditor {      @Override      public void setAsText(String text) throws IllegalArgumentException {        if (text == null || text.equals("")) {          text = "0";        }        setValue(Double.parseDouble(text));      }          @Override      public String getAsText() {        return getValue().toString();      }    }     public class IntegerEditor extends PropertiesEditor {      @Override      public void setAsText(String text) throws IllegalArgumentException {        if (text == null || text.equals("")) {          text = "0";        }        setValue(Integer.parseInt(text));      }          @Override      public String getAsText() {        return getValue().toString();      }    } }
