骆驼示例找不到org.apache.camel.impl.DefaultComponent [英] Camel example can't find org.apache.camel.impl.DefaultComponent

问题描述

我创建了一个小的Apache Camel示例，但找不到类org.apache.camel.impl.DefaultComponent. 此处完整的错误日志.

I've created a small Apache Camel example, but it can't find the class org.apache.camel.impl.DefaultComponent. Here the full error log.

我在搜索中查找了该类.maven.org ，该文件应包含在org.apache.camel:camel-core中.添加它不能解决我的问题. 此示例出了什么问题?

I've looked the class up on search.maven.org, which says it should be contained in org.apache.camel:camel-core. Adding it does not solve my problem. What's wrong in this example?

这是应用程序

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(Application.class);
        app.setWebApplicationType(WebApplicationType.NONE);
        app.run(args);
    }
}

和这里的路线.

@Component
public class ZmqRoute extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        //from("stream:in").to("stream:out");

        String host = "zmq.devnet.iota.org";
        from("zeromq:tcp://" + host + ":5556?socketType=SUBSCRIBE&topics=tx")
                .to("stream:out")
                .log("${body}");
    }
}

最后，这里是build.gradle.kts

plugins {
    java
    application
    id("org.springframework.boot") version "2.1.2.RELEASE"
    id("io.spring.dependency-management") version "1.0.6.RELEASE"
}

repositories {
    jcenter()
}

application {
    mainClassName = "org.example.camel.Application"
}

java {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

tasks.withType<JavaCompile>().configureEach {
    options.compilerArgs.addAll(arrayOf("-Xlint:all"))
    options.encoding = "UTF-8"
}

dependencies {
    val camelVersion = "3.0.0-M1"

    implementation("org.springframework.boot:spring-boot-starter-web")

    implementation("org.apache.camel:camel-spring-boot-starter:$camelVersion")

    implementation("org.apache.camel:camel-stream-starter:$camelVersion")

    //implementation("org.apache.camel:camel-core:$camelVersion")

    implementation("org.apache-extras.camel-extra:camel-zeromq:2.22.0") {
        exclude(module = "zeromq-scala-binding_2.10")
    }

    implementation("org.zeromq:jeromq:0.5.0")

    testImplementation("junit:junit:4.12")
}

推荐答案

因此，基本上，在查看Camel Core 3.0.0.M1之后，我发现了

So basically, after looking at Camel Core 3.0.0.M1, I discovered the .class file for

org.apache.camel.impl.DefaultComponent

不再存在！

camel-core-3.0.0-M1.jar\org\apache\camel\impl 

老实说，这对我来说似乎是个错误，或者与core-zeromq不兼容.

Honestly it seems like a bug to me, or incompatibility with core-zeromq.
