javax.activation.UnsupportedDataTypeException：MIME类型为multipart / mixed的无对象DCH；边界

25-02-27 10

如果您想了解javax.activation.UnsupportedDataTypeException：MIME类型为multipart/mixed的无对象DCH；边界的知识，那么本篇文章将是您的不二

如果您想了解javax.activation.UnsupportedDataTypeException：MIME类型为multipart / mixed的无对象DCH；边界的知识，那么本篇文章将是您的不二之选。同时我们将深入剖析Android – java.lang.UnsupportedOperationException：无法转换为dimension：type = 0x12、Android’InvocationTargetException’和’UnsupportedOperationException’、Caused by: java.lang.UnsupportedOperationException、hibernate---java.lang.UnsupportedOperationException: The user must supply a JDBC connection的各个方面，并给出实际的案例分析，希望能帮助到您！

javax.activation.UnsupportedDataTypeException：MIME类型为multipart / mixed的无对象DCH；边界

目前，我正在编写要侦听目录的代码。当目录使用.apk文件更新时，我会将带有此.apk文件的邮件发送到gmail帐户。我在程序中使用Jnotify和JAVA
Mail。

我得到的错误是

javax.mail.MessagingException: IOException while sending message;  nested exception is:javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/mixed; boundary="----=_Part_0_145238.1392728439484"

我寻找了stackoverflow中给出的解决方案以寻求帮助，但没有一个有帮助。

通过采取以下两个步骤，可以解决此问题。

确保Java邮件为1.4.7。（以前我使用1.4.5导致了所有混乱）。从http://www.oracle.com/technetwork/java/index-138643.html下载

在发送消息之前添加以下代码：

Thread.currentThread().setContextClassLoader( getClass().getClassLoader() );

Android – java.lang.UnsupportedOperationException：无法转换为dimension：type = 0x12

我正在尝试为我的Android应用程序创建一个UI,但它崩溃了,错误就是

“java.lang.RuntimeException: Unable to start activity

我做错了什么？有任何想法吗？

解决方法:

您在此行提供了无效资源：

android:layout_marginTop="@+id/RadioButton03"

尺寸应该用于保证金,例如

android:layout_marginTop="@dimen/margin_top"

Android’InvocationTargetException’和’UnsupportedOperationException’

我在OPPO X905和OPPO X907上遇到了问题,两者都是 Android 4.0.3(API等级15),我没有使用任何更高级别的API,我在Google和SO上搜索过,都与我的问题不同,下面是我的xml文件和崩溃日志,在此先感谢.

CarRouteShowItem.java:78的代码是这样的：

View mView = LayoutInflater.from(mContext).inflate(R.layout.car_route_detail_item,null);

CarRouteShowItem不是View的子代,其代码如下：

public class CarRouteShowItem {

    private Context mContext;

    private View mView;

    public CarRouteShowItem(Context context) {
        mContext = context;

        // mView is used by caller 
        mView = LayoutInflater.from(mContext).inflate(R.layout.car_route_detail_item,null);

        // some view finds 
    }

        // some other methods related with specific logic
}

图形布局可以在Eclipse中从API级别8预览到API级别23,但是当我在API级别15的Android Studio中预览时,它会显示错误消息：无法解析资源@style / Widget.TextView,其他API级别没问题,但我没有使用TextView的样式.

解决方法

你需要的只是一个额外的眼睛:-)

android:layout_height="1px"

希望你现在能看到.第二个RelativeLayout中的最后一个子项,其id为item_second_half,类型为< View,将其更改为

android:layout_height="1dp"

索噶，原来返回的是Arrays类的静态内部类！这样能会报错也就正常咯。

hibernate---java.lang.UnsupportedOperationException: The user must supply a JDBC connection

后来看了后台的源代码，发现创建的 ConnectionProvider 实例为 UserSuppliedConnectionProvider（用户自己定义的 Provider），配置有点异常。断点跟踪了创建该实例的代码，原来是由于在依据各个配置属性创建该实例时。由于配置属性 keyword 与 hibernatekeyword 不一样。所以导致创建了用户自己定义的 Provider，从而出现了上面的异常。

測试代码使用的是 hibernate 3.5.6。标准的 keyword 能够查看 org.hibernate.cfg.Environment 类中的定义。

hibernate 版本号不一样，使用的 keyword 也不一样。

这点须要注意。

hibernate 3.5.6 使用的是：

hibernate.connection.driver_class
hibernate.connection.url
hibernate.connection.username
hibernate.connection.password
