java - 在运行时将 netty-tcnative 添加到 Tomcat

Question

我在 Eclipse 中有一个动态 Web 项目，具有以下 Maven 设置

</project>

我已经将这两个jar添加到WEB-INF下的LIB目录

netty-tcnative-1.1.33.Fork9-osx-x86_64.jar
alpn-api-1.1.2.v20150522.jar

我还尝试将这些添加到 setenv.sh 文件中的 tomcat CLASSPATH:

   CLASSPATH="/Users/williammcerlane/.m2/repository/org/eclipse/jetty/alpn/alpn-api/1.1.2.v20150522/alpn-api-1.1.2.v20150522.jar"
CLASSPATH="$CLASSPATH /Users/williammcerlane/.m2/repository/io/netty/netty-all/4.1.0.CR7/netty-all-4.1.0.CR7.jar"

但是在运行时，我的进程崩溃了，找不到:

 DEBUG io.netty.util.internal.NativeLibraryLoader  – Unable to load the library: netty-tcnative-osx-x86_64.
java.lang.UnsatisfiedLinkError: no netty-tcnative-osx-x86_64 in java.library.path

这让我很困惑是什么试图加载 jar 但找不到它。

完整错误:

Answer 1

首先，这个线程说要先加载 libapr-1 和 OpenSSL 才能使用这个 jar

Forked Tomcat Native

其次，您可以尝试 java -Djava.library.path=。 -jar netty-tcnative-VER.jar
