工作中用到反射，代码记录如下
public String callXMLHandler(Object obj) throws IllegalArgumentException, IllegalAccessException{
Class<? extends BaseRequestBean> clazz = (Class<? extends BaseRequestBean>)obj.getClass();
Class<BaseRequestBean> clazzSuper = (Class<BaseRequestBean>) clazz.getSuperclass();//获得父类的Class
Field field[] = clazz.getDeclaredFields();//getDeclaredFields 无法获得继承属性
//System.out.println(field.length);
Field fieldSuper[] = clazzSuper.getDeclaredFields();//获得父类属性
//System.out.println(fieldSuper.length);
XMLEntity e = new XMLEntity();
for (Field f1 : field) {
f1.setAccessible(true);//取消访问权限检查，以便能够访问非公共属性
System.out.println(f1.getName()+","+f1.get(obj));
e.body.put(f1.getName(), (String)f1.get(obj));
}
for (Field f2 : fieldSuper){
f2.setAccessible(true);
e.head.put(f2.getName(), (String)f2.get(obj));
}
String str = buildXML.buildXMLStrByXMLEntity(e);
return str;
}
obj中对象属性未使用public修饰，之前未添加f1.setAccessible(true)，运行时报错: java.lang.IllegalAccessException: Class union.web.mvc.services.base.InvokeXMLStr can not access a member of class union.web.mvc.services.dataDictionary.addTable.AddTableReqBean with modifiers ""
getDeclaredFields()方法无法获得继承属性
getFields()方法无法获得非公共属性
getDeclaredMethods()和getMethods()也同理
