java.lang.NoSuchMethodError : org. springframework.boot.builder.SpringApplicationBuilder.([Ljava/lang/Object;)V

Question

我正在编写简单的应用程序以熟悉 spring 批处理。我想学习 spring 批处理管理，但我发现它已被弃用，所以我必须改用 spring 云数据流。

我找到了一个关于 spring 云数据的教程，并做了第一步:

添加依赖:

编译(“org.springframework.cloud:spring-cloud-starter-dataflow-server-local:1.7.4.RELEASE”)

并用 additioanl annotaion 标记我的 Spring Boot 应用程序类:

@EnableDataFlowServer

现在我正在尝试使用idea运行它，但它会打印:

10:24:09.590 [main] ERROR org.springframework.boot.SpringApplication - Application run failed

Answer 1

在大多数情况下，这要么是由于缺少依赖项，要么是由于较旧的 spring/spring boot 版本附带的依赖项。
检查您的 maven 依赖树并搜索比您的父启动器请求的版本更旧的 spring-boot 依赖项。大概 org.springframework.cloud:spring-cloud-starter-dataflow-server-local:1.7.4.RELEASE带有旧版本，您需要将其排除。
