java - 添加 Openfeign 依赖时出现 java.lang.IllegalStateException

Question

我正在使用 Spring Boot 创建基于休息的服务。一切正常。

现在我添加了以下依赖项

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-openfeign </artifactId>
        </dependency>

添加此后，Spring boot 应用程序停止工作，并给出以下错误:

Exception in thread "main" java.lang.IllegalStateException: Failed to read Class-Path attribute from the manifest of jar file:/C:/Users/nicky/.m2/repository/commons-lang/commons-lang/2.6/commons-lang-2.6.jar

有人可以帮我解决这个错误吗？

看起来本地 maven 存储库中的 commons-lang-2.6.jar 依赖 jar 已损坏 .

现在就你的情况来说:

• 从以下位置删除 jar:

  文件:/C:/Users/nicky/.m2/repository/commons-lang/commons-lang/2.6/

  并重建您的应用程序。

• 在您的 pom.xml 中，依赖项下方

  <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-openfeign </artifactId>
  </dependency>
  

  spring-cloud-starter-openfeign 之后的 artifactId 中有一个空格，请删除它。

经过上述两件事后它应该可以工作。

希望这有帮助。
