这个是基类BaseAction：
[java]
public class BaseAction {
@InitBinder
protected void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"), true));
binder.registerCustomEditor(int.class, new IntegerEditor());
binder.registerCustomEditor(long.class, new LongEditor());
binder.registerCustomEditor(double.class, new DoubleEditor());
binder.registerCustomEditor(float.class, new FloatEditor());
}
}
下面是各个编辑器类：
Spring提供了CustomNumberEditor，也可以不用些编辑器类。使用构造函数构造相应的编辑器类。
[java]
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();
}
}
[java]
import org.springframework.beans.propertyeditors.PropertiesEditor;
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();
}
}
[java]
public class LongEditor extends PropertiesEditor {
@Override
public void setAsText(String text) throws IllegalArgumentException {
if (text == null || text.equals("")) {
text = "0";
}
setValue(Long.parseLong(text));
}
@Override
public String getAsText() {
return getValue().toString();
}
}
[java]
public class FloatEditor extends PropertiesEditor {
@Override
public void setAsText(String text) throws IllegalArgumentException {
if (text == null || text.equals("")) {
text = "0";
}
setValue(Float.parseFloat(text));
}
@Override
public String getAsText() {
return getValue().toString();
}
}
