Question

尝试使用最新的camle pgp加密，但看到Caused by: java.lang.NoSuchMethodError: org.bouncycastle.openpgp.PGPPublicKeyRingCollection错误，我已经检查过我在classpath上有正确版本的camel和bouncy castle jar，也尝试过最新的1.59 bc版本。 - 我错过了什么吗？

mvn dependency:tree|egrep 'bcp|crypto'

测试路线：

  class DeadLetterChannelRoute1 extends RouteBuilder {

        @Override
        public void configure() throws Exception {
            from("file:source/inbox")
                    //.errorHandler(deadLetterChannel("file:source/dlc1").useOriginalMessage())
                    .process(exchange -> System.out.println( "1 >>> BEFORE:\n " + exchange.getIn().getBody(String.class)))
                    .marshal().pgp(encryptKeyFileName,encryptKeyUserid)
                    .process(exchange -> System.out.println( "1 >>> AFTER: \n" +  exchange.getIn().getBody(String.class)))
                    .to("file:source/pgp_inbox");
        }
    }

编辑：还检查在运行时这些jar是在类路径中：:~/.m2/repository/org/bouncycastle/bcpg-jdk15on/1.57/bcpg-jdk15on-1.57.jar:~/.m2/repository/org/bouncycastle/bcprov-jdk15on/1.57/bcprov-jdk15on-1.57.jar:

所以事实证明jdk版本不是问题，但问题是我们在java安装$JAVA_HOME/jre/lib/ext目录中使用.out重命名旧的bc jar时我们假设这些jar没有加载到classpath上，但似乎它们确实被加载了。当我从$JAVA_HOME/jre/lib/ext完全删除这些旧jar时，一切都适用于java 8版本121和172.
