使用Maven和Spring引导的Spring会话示例中的Redis错误

我试图使用SpringBoot+Maven进行设置（GIT链接中的源代码使用的是Gradle）。没有编译错误，可部署的WAR文件也是使用重新打包目标生成的

当尝试在我的WildFly服务器中部署WAR文件时，我遇到了以下与Redis相关的错误。我的机器上没有运行Redis服务器（因为我假设嵌入式Redis实例将作为应用程序的一部分创建，即使是在部署的WAR文件中）

文件：EmbeddedRedisConfiguration.java

由引起：

java.lang.NullPointerException
at java.util.Objects.requireNonNull(Objects.java:203) [rt.jar:1.8.0_25]
at java.nio.file.Files.copy(Files.java:2984) [rt.jar:1.8.0_25]
at redis.embedded.RedisServer.extractExecutableFromJar(RedisServer.java:85)
at redis.embedded.RedisServer.<init>(RedisServer.java:69)
at redis.embedded.RedisServer.<init>(RedisServer.java:63)
at hello.EmbeddedRedisConfiguration$RedisServerBean.afterPropertiesSet(EmbeddedRedisConfiguration.java:55)

java.lang.NullPointerException
在java.util.Objects.requirennull（Objects.java:203）[rt.jar:1.8.0_25]
在java.nio.file.Files.copy（Files.java:2984）[rt.jar:1.8.0_25]
位于redis.embedded.RedisServer.extractExecutableFromJar（RedisServer.java:85）
位于redis.embedded.rediserver。（RedisServer.java:69）
位于redis.embedded.rediserver。（RedisServer.java:63）
位于hello.EmbeddedRedisConfiguration$RedisServerBean.AfterPropertieSet（EmbeddedRedisConfiguration.java:55）

环境：以域模式运行的WildFly8.2（3个节点以完整HA配置文件运行） 应用程序：Spring启动+Spring会话+Maven

问题：此错误是因为无法创建嵌入式Redis实例吗 在WAR文件部署到容器时创建？我没有 已尝试将此作为可执行WAR文件运行
