带有响应参数的方法中的IllegalStateException（响应方式）
我编写了一个简单的类来测试响应读取实体方法（如果它按我的预期工作）。但是效果不佳。
当我启动课程时，出现以下错误response.readEntity()：
Exception in thread "main" java.lang.IllegalStateException: Method notsupported on an outbound message.
at
org.glassfish.jersey.message.internal.OutboundJaxrsResponse.readEntity(OutboundJaxrsResponse.java:150)
这是我写的代码
public static void main(String[] args) { List<Entity> representations = new ArrayList<>(); representations.add(new Entity("foo", "baz", false)); representations.add(new Entity("foo1", "baz1", true)); representations.add(new Entity("foo2", "baz2", false)); Response build = Response.ok(representations).build(); printEntitesFromResponse(build); }public static void printEntitesFromResponse(Response response) { response .readEntity(new GenericType<List<Entity>>() {}) .stream() .forEach(entity -> System.out.println(entity)); }我究竟做错了什么？
答案1
小编典典Responsees 有两种类型，入站和出站，尽管它们仍使用相同的接口。出站是从服务器发送响应时
Response response = Response.ok(entity).build();入站是指您在客户端上收到响应时。
Response response = webTarget.request().get();readEntity在服务器端出站响应上禁用了该方法，因为您不需要它。仅在需要对响应流的响应进行_de_serialize时使用。但是出站时没有任何东西。
如果您希望实体出站响应，只需使用Response#getEntity()
android – 使用PagerAdapter的IllegalStateException
private class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fragmentManager) {
super(fragmentManager);
}
@Override
public Fragment getItem(int position) {
QuickContactListFragment fragment = new QuickContactListFragment();
final String mimeType = mSortedActionMimeTypes.get(position);
final List<Action> actions = mActions.get(mimeType);
fragment.setActions(actions);
return fragment;
}
@Override
public int getCount() {
return mSortedActionMimeTypes.size();
}
}
这是崩溃日志：

IllegalStateException片段已添加
正确，我们的crashlytics日志中也有相同的异常。解决它的方法很少。
1。
因此，在大多数情况下，这是因为commitAllowingStateLoss()。这不仅是因为文档所述的交易过程中的“保存状态”。它将使用先前的状态来重新创建Fragment，根据我们的经验，它与流程或Fragment交易直接相关。
所以首先。删除它的用法，然后修复您的交易状态设置。您不想在片段可能位于堆栈中的位置使用commitAllowingStateLoss()，而是要重用它。 （就像上面的代码段一样。）
2。
我很确定您的问题是由上述第1点引起的。但是，还有另一个原因已经在评论中提到。 FragmentTransactions是异步提交的。因此，您需要致电executePendingTransactions()，有关更多信息，请参考here。
IllegalStateException：无法自省类
通过如下更改server.xml来解决它
<library id="extension">
<fileset dir="${server.config.dir}/ext" includes="*.jar" scanInterval="5s" />
</library>
<webApplication id="Myapp" location="Myapp.war" type="war" name="Myapp" contextRoot="/resources">
<classloader commonLibraryRef="extension" delegation="parentFirst"/>
</webApplication>
