这个项目运行了2快两年了 就今天这个问题导致程序内存溢出崩溃好几次了
还没有找到问题在哪里 最近也没有啥大的改动
看起来是哪里死循环了? Jfinal版本是1.5
android中的java.lang.reflect.invocationtargetexception
我遇到了问题,我的xml文件如下
<ImageView
android:id="@+id/edt_order"
android:layout_width="50dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_below="@+id/separator_bottom"
android:background="#fff"
android:clickable="true"
android:onClick="clickHandler"
android:src="@drawable/edit_button" />
<ImageView
android:id="@+id/save_change_order_id"
android:layout_width="100dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_below="@+id/separator_bottom"
android:background="#fff"
android:clickable="true"
android:visibility="gone"
android:onClick="clickHandler"
android:src="@drawable/save_button" />
实际上这是定义自定义alert-dialog的xml的一部分.我希望当我点击第一个ImageView(android：id =“@ id / edt_order”)时,它的可见性变为Invisible而代替这个ImageView setvisible另一个ImageView(android：id =“@ id / save_change_order_id”)
为此,我在java文件中写下以下代码：
public void clickHandler(View v) {
if (v.getId() == R.id.edt_order) {
System.out.println(" edit buton click");
System.out.println("Click my Order");
img_v_save_change_order_var.setVisibility(ImageView.VISIBLE);
img_btn_edit_order_var.setVisibility(ImageView.INVISIBLE);
int jcount = 0;
// save_change_order_id
jcount = countjournals();
System.out.println("jcount = " + jcount);
if (jcount < 1) {
alertShow();
} else {
intiliazeOrderListDialog();
}
}
}
但我得到的例外情况如下：

为什么我得到这个例外？
解决方法
我认为这是主要课堂的形象宣言的问题.
applet中的java.lang.reflect.invocationtargetexception错误
我的应用程序作为一个应用程序运行时没有错误，但是作为一个applet引发了以下错误：
java.lang.reflect.invocationtargetexception
这是我第一次尝试将应用程序用作applet，因此我可能做错了一些，但这是我的主要课程：

Exception in thread “main“ java.io.IOException: java.lang.reflect.InvocationTargetException
关于使用HBase-1.3.1版本 API 运行时出现 Exception in thread "main" java.io.IOException: java.lang.reflect.InvocationTargetException 异常的原因和解决方案
一 现象
二 原因
HBase-1.3.1版本和JDK版本不匹配，可以使用JDK1.7或者JDK1.8
三 解决办法：改JDK版本
（0）安装JDK1.8或者JDK1.7版本，要记得安装路径，等一下要用，比如我的安装路径是：
（1）点击Window下的Preferences
（2）添加JDK1.8或者JDK1.7的根目录
（3）添加JDK1.8或者JDK1.7
a)
b) 点击Directory找到你刚刚JDK的安装目录
c）上一步完整之后，点击Apply and Close
（4）修改当前项目的jdk
a)
b)
c)
d)
e)选择JDK1.8或者JDK1.7
f)最后点击Apply and Close ，然后重新运行程序就没问题啦！！！
hibernate bean 的 toJSon JSONException: java.lang.reflect.InvocationTargetException
将hibernate的 对象 使用 转换成json 对象的时候报错
JSONException: java.lang.reflect.InvocationTargetException
从错误异常，完全看不出是什么原因。
网上查询，一般都说是 时间 date 类型 转换的时候报错的。
那么我使用
JsonConfig cfg = new JsonConfig();
String[] excludes = { "date"};
都过滤掉 date 的字段属性，还是报错了。
只是有一个奇怪的地方，就是 新增和编辑的时候没有问题。只是在 其他地方引用这个对象的时候， 然后转换json的时候就报错了。
也是有点奇怪。
参考 https://blog.csdn.net/ye1992/article/details/17436765#reply
String[] excludes = 加上了 "handler", "hibernateLazyInitializer"
JsonConfig cfg = new JsonConfig();
String[] excludes = { "handler", "hibernateLazyInitializer" };
就解决了这个问题。 估计是 因为
只是在 其他地方引用这个对象的时候，可能是因为hibernate 懒加载出的对象，因此出了点其他的问题吧。
关于java.lang.RuntimeException: java.lang.reflect.InvocationTargetException的问题就给大家分享到这里，感谢你花时间阅读本站内容，更多关于android中的java.lang.reflect.invocationtargetexception、applet中的java.lang.reflect.invocationtargetexception错误、Exception in thread “main“ java.io.IOException: java.lang.reflect.InvocationTargetException、hibernate bean 的 toJSon JSONException: java.lang.reflect.InvocationTargetException等相关知识的信息别忘了在本站进行查找喔。
