一个非法的反射访问操作在设置Spring XD时发生了。

javaspringjava-8java-9spring-xd

我正在按照Spring XD指南在Windows 7上安装Spring XD。当我尝试启动运行时和XD shell并输入./xd-singlenode时，它给出了以下警告和错误：

注：

  1. 我正在使用 Windows 7 命令行提示符。

  2. 我在系统设置中附加了 Java 8 和 Java 9 的 bin 目录到路径中。

  3. 我搜索了类似的问题，但没有找到解决方法，例如什么是非法反射访问，Apache POI 发生了非法反射访问操作。

那么我该怎么做或者我错过了什么？

我通过将 JAVA_HOME 用户变量设置为 jdk8 文件夹的路径 (例如 C:\Program Files\Java\jdk1.8) 来解决它，因为一些 Spring 依赖项不支持 JDK 9。

首先，这是一个警告，其次是jre在9版本中抛出该警告。 我将Java 8和Java 9的bin目录附加到系统设置的路径中 - 这意味着什么？为什么两个都要添加？ - Eugene
Spring XD不再得到积极维护，已被Spring Cloud Data Flow暂停。 - M. Deinum

在这里的理想建议是信任库的开发人员并迁移到Cloud Data Flow，如上所述。

注意：该项目自2017年7月起已处于EOL / EOS状态。请查看Spring Cloud Data Flow和生态系统项目以进行进一步的研究，探索和用例实现。

为了帮助您，这里有一个关于从Spring XD迁移到Spring Data Cloud Flow的指南。

另一方面，为了详细说明您分享的日志内容 -

  1. 警告：Illegal reflective access by org.codehaus.groovy.reflection.CachedClass$3$1 (file:/C:/Users/user/SpringXD/spring-xd-1.3.2.RELEASE/xd/lib/groovy-all-2.4.4.jar) to method java.lang.Object.finalize()

    警告：请考虑向org.codehaus.groovy.reflection.CachedClass$3$1的维护者报告此问题

    这是JDK9+的一种警告方式，用于警示您非法反射访问，而它所读到的最合适的内容莫过于“请考虑向org.codehaus.groovy.reflection.CachedClass的维护者报告此问题”。

  2. Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at org.hibernate.validator.internal.util.Version.getJavaRelease(Version.java:36) ~[hibernate-validator-5.2.1.Final.jar:5.2.1.Final]

    这是您应用程序失败的实际原因，由于spring-xd中缺乏兼容性修复。虽然spring-data-cloud-flow似乎也没有完全解决它,但仍可以使其正常工作。

谢谢，我通过设置正确的JDK 8值来解决了它，即JAVA_HOME变量。 - Noura
