尝试连接到 Azure Eventhub 时出错：AzureTokenCredentials / IllegalArgumentException: name

Question

我正在关注有关如何在 Spring Boot 中设置与 Azure EventHub 的连接的教程：[1]

启动 spring boot 应用时，出现以下错误：

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

my.azureauth 看起来类似于 [1] 中的 on。

我正在使用 Java 11。这是我的 pom 的相关部分：

        <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>

注意关于依赖 com.nimbusds 的解决方法。

我尝试导航到相关代码。但是，由于某种原因，AzureContextAutoConfiguration.credentials 的代码 在我的 IDE 的反汇编代码中不可用。

我在pom.xml 中的解决方法中使用的版本是否合适？ 有谁知道错误的含义以及如何解决它？ 任何人都可以报告本教程仍然有效吗？

Answer 1

所以这里的根本问题是

"实例化失败 [com.microsoft.azure.credentials.AzureTokenCredentials]：工厂方法“凭据”抛出异常； 嵌套异常是 java.lang.IllegalArgumentException: name"

我建议您根据guide 再次验证您的my.azureauth 和application.properties 文件。

另外，正如guide 所建议的，如果您使用的是 JDK 版本 9 或更高版本（这里使用的是 11），请添加以下依赖项

<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>
