SpringMVC数据绑定四（自定义的类型转换器）

1、PropertyEditor

　　继承PropertyEditorSupport

//controller
@Controller
public class TestController extends PropertyEditorSupport{
     //重写PropertyEditorSupport的setAsText方法
@Override
    public void setAsText(String text) throws IllegalArgumentException {
        User u = new User();
        String[] textArray = text.split(",");
        u.setName(textArray[0]);
        u.setAge(Integer.parseInt(textArray[1]));
        this.setValue(u);
    }
    
     //TODO: http://127.0.0.1:8080/SpringMVC/propertyEditir?text=Tom,20
    @RequestMapping(value="propertyEditir")
    @ResponseBody
    public String propertyEditir(String text) {
        this.setAsText(text);
        return ((User)this.getValue()).toString();
    }

}
