Question

我正在使用spring boot 1.4.x开发一个Web服务，并将其部署在支持java 6的Websphere 8.5中。但是当我在WAS中部署我的战争时，我遇到了错误。

看起来Spring引导中的一个jar依赖项（spring-ws-core-2.3.1.RELEASE.jar）有使用java编译的类7.Which导致以下错误。

使用Spring Boot 1.4.x需要什么样的最低java版本？在我的情况下，是否可以单独覆盖上面的依赖项以降低版本？

According to the reference documentation：

默认情况下，Spring Boot 1.4.4.RELEASE需要Java 7和Spring Framework 4.3.6.RELEASE或更高版本。您可以使用带有Java 6的Spring Boot和一些其他配置。有关详细信息，请参阅Section 81.11, “How to use Java 6”。为Maven（3.2+）和Gradle（1.12或2.x）提供显式构建支持。不推荐支持Gradle 2.8及更早版本。不支持Gradle 3。

您遇到问题的依赖项不是Spring Boot，而是单独的Spring Web Services which is only compatible with Java 7：

Spring Web Services需要标准的Java 7运行时环境。 Java 8也受支持。 Spring-WS构建于Spring Framework 4.0.9之上，但支持更高版本。

你可以尝试降级或排除依赖关系，但是你有很高的风险会破坏某些东西。

什么是Spring Boot 1.4.x所需的最低java版本
