spring-flex 1.5.2 JUnit測試錯誤servletContext null

Question

我的項目flex 4 + spring-flex 1.5.2 + spring 3.1 + hibernate 3.6（jpa2.0），可以在瀏覽器中運行，但不適用於JUnit4。

JUnit錯誤：

我的配置文件有問題嗎？

Answer 1

我對<flex:message-broker />發表了評論。。。它很好..它找不到servletconfig。

解決方案2：將注釋添加到測試類中

@WebAppConfiguration

編輯1：其他方法您可以在這里查看spring人員的答案。http://forum.springsource.org/showthread.php?74055-Junit4-errors-with-Application-Context-and-BlazeDS

因此，您需要模擬Web請求，以使messagebroker初始化成功。
