嘗試連接到 Azure Eventthub 時出錯：AzureTokenCredentials / IllegalArgumentException：名稱

Question

我正在關注如何在 Spring 引導中設置與 Azure EventHub 的連接的教程：[1]

啟動 spring 啟動應用程序時，出現以下錯誤：

2021-01-07 13:37:25.447  WARN 16444 --- [           main] ConfigServletWebServerApplicationContext :

nested exception is java.lang.IllegalArgumentException: name

my.azureauth 看起來類似於 [1] 中的 on。

我正在使用 Java 11。這是我的 pom 的相關部分：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.microsoft.azure</groupId>
            <artifactId>spring-cloud-azure-eventhubs-stream-binder</artifactId>
            <version>1.2.7</version>
        </dependency>
        <dependency>
            <groupId>com.microsoft.azure</groupId>
            <artifactId>azure-servicebus-jms-spring-boot-starter</artifactId>
            <version>2.3.5</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- Workaround. -->
        <!-- Apparently com.microsoft.azure:spring-cloud-azure-eventhubs-stream-binder:1.2.7 has a transitive -->
        <!-- dependency to the following package. However, it seems that the version is not pinned correctly, so -->
        <!-- we have to pin the version to a compatible one as a workaround. -->
        <!-- 7.5 is apparently the latest version in which com.nimbusds.oauth2.sdk.http.CommonContentTypes is available. -->
        <!-- For a similar (but different) issue see also https://github.com/microsoft/azure-spring-boot/issues/650 -->
        <dependency>
            <groupId>com.nimbusds</groupId>
            <artifactId>oauth2-oidc-sdk</artifactId>
            <version>7.5</version>
        </dependency>

請注意有關依賴com.nimbusds的解決方法。

我嘗試導航到相關代碼。 但是，由於某種原因， AzureContextAutoConfiguration.credentials的代碼在我的 IDE 的反匯編代碼中不可用。

我在pom.xml中的解決方法中使用的版本是否合適？ 有誰知道錯誤的含義以及如何解決它？ 任何人都可以報告本教程仍然有效嗎？

Answer 1

所以這里的根本問題是

“無法實例化 [com.microsoft.azure.credentials.AzureTokenCredentials]：工廠方法 'credentials' 拋出異常；嵌套異常是 java.lang.IllegalArgumentException：名稱”

我建議您根據指南再次驗證您的my.azureauth和application.properties文件。

此外，正如指南所建議的，如果您使用的是 JDK 9 或更高版本（您在這里使用的是 11），請添加以下依賴項

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.1</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jaxb</groupId>
    <artifactId>jaxb-runtime</artifactId>
    <version>2.3.1</version>
    <scope>runtime</scope>
</dependency>
