我有一个spring boot camel hello world应用程序,我想部署到Bluemix:
import org.apache.camel.spring.boot.*
import org.springframework.boot.*
import org.springframework.boot.autoconfigure.*
import org.springframework.context.*
import org.springframework.context.annotation.*
import org.springframework.scheduling.annotation.*
@Configuration
@ComponentScan
@EnableAutoConfiguration
@SpringBootApplication
class Application extends FatJarRouter {
public static void main(String... args) {
ApplicationContext applicationContext = new SpringApplication(Application.class).run(args);
CamelSpringBootApplicationController applicationController =
applicationContext.getBean(CamelSpringBootApplicationController.class);
applicationController.run();
}
@Override
public void configure() throws Exception {
from("netty4-http:http://0.0.0.0:18080").
setBody().simple("ref:helloWorld");
}
@Bean
String helloWorld() {
return "helloWorld";
}
}
我也发布了我的build.gradle以防它有用:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.3.RELEASE")
}
}
apply plugin: 'java'
apply plugin: 'groovy'
apply plugin: 'spring-boot'
apply plugin: 'eclipse'
jar {
baseName = 'EAI_Service'
version = '0.1.0'
}
repositories {
mavenCentral()
}
dependencies {
compile("org.codehaus.groovy:groovy-all:2.2.1")
compile("org.springframework.boot:spring-boot-starter-web:1.2.3.RELEASE")
compile("org.apache.camel:camel-core:2.17.0")
compile("org.apache.camel:camel-spring-boot-starter:2.17.0")
compile('org.apache.camel:camel-netty4-http:2.17.0')
}
task wrapper(type: Wrapper) {
gradleVersion = '2.0'
}
在Bluemix日志文件中,我可以看到camel绑定到端口:
ServerBootstrap binding to 0.0.0.0:18080
Netty consumer bound to: 0.0.0.0:18080
Route: route1 started and consuming from: Endpoint[http://0.0.0.0:18080]
Total 1 routes, of which 1 are started.
Apache Camel 2.17.0 (CamelContext: camel-1) started in 0.590 seconds
Tomcat started on port(s): 61649 (http)
Started Application in 7.345 seconds (JVM running for 9.164)
Apache Camel 2.17.0 (CamelContext: camel-1) is starting
Total 1 routes, of which 1 are started.
Apache Camel 2.17.0 (CamelContext: camel-1) started in 0.000 seconds
但是,当我尝试连接时,会返回“拒绝连接”消息。
snowch$ curl <<myapp>>.mybluemix.net:18080
curl: (7) Failed to connect to <myapp>>.mybluemix.net port 18080: Connection refused
在我的用例中,camel使用netty侦听端口18080.我看到{{3}}表示无法绑定到Bluemix Liberty应用程序上的自定义端口。是否有其他方法可以在不使用Docker或VM的情况下支持此用例?
答案 0 :(得分:1)
Bluemix运行时实际上不允许使用自定义端口,唯一允许使用的是http / https,通过TCP使用80和443
IBM容器允许来自端口子集的自定义端口,无论如何都必须在docker文件上公开它们。
虚拟服务器测试版允许您使用自定义端口,您必须相应地在openstack上设置安全策略(或者只是打开所有端口,即使不是很安全)
