java - ALPN 回调下降 : SPDY and HTTP/2 are disabled. alpn-boot 是否在引导类路径上？

Question

尝试让 Apple 推送通知与我的 Spring Boot 项目一起工作。

我正在使用此 apns-http2 发送推送通知。从他们的 GitGub 页面:

Note: Ensure that you have Jetty's ALPN JAR (OkHttp requires it) in your boot classpath. See here for more information. This is required until Java 9 is released, as Java 8 does not have native support for HTTP/2.

所以我添加了vm选项

Xbootclasspath/p:/Users/sarath/.m2/repository/org/mortbay/jetty/alpn/alpn-boot/8.1.9.v20160720//alpn-boot-8.1.9.v20160720.jar

在 Intellij 中运行配置，一切正常。我收到推送通知。

但是当我将 war 部署到 tomcat 并尝试发送推送通知时，出现错误:

我不确定如何在引导类路径上设置 alpn-boot。我尝试执行

java -Xbootclasspath/p:/Users/sarath/.m2/repository/org/mortbay/jetty/alpn/alpn-boot/8.1.9.v20160720/alpn-boot-8.1.9.v20160720.jar

从命令提示符。但这只显示了一些 Java 帮助命令。不知道这个jar是不是真的加入了boot类路径。

我也试过使用 maven-surefire-plugin 就像它说的 here .但仍然出现同样的错误。

这是我的 pom.xml

我尝试了很多其他的东西，但似乎没有任何效果。

Answer 1

正如 AlexanderPavlov 在评论中指出的那样。

If it must be on bootpath then you have to put it somewhere and add -Xbootclasspath option to java command-line arguments in catalina.bat/.sh

我在 Tomcat_Home/bin/中创建了一个名为 setenv.sh 的文件

setenv.sh

export CATALINA_OPTS="-Xbootclasspath/p:/Users/sarath/.m2/repository/org/mortbay/jetty/alpn/alpn-boot/8.1.9.v20160720//alpn-boot-8.1.9.v20160720.jar"

catalina.bat/.sh 将自动读取 setenv.sh(如果存在)。
