[英]Spring Boot Camel Testing - No consumers available on endpoint
我正在我的 Spring Boot,Camel 应用程序中测试 Spring 安全性。 当我尝试使用 Autowired ProducerTemplate 测试路由时,会引发异常并显示消息“端点上没有可用的消费者:direct://secure”。 该路线在骆驼上下文中正确定义。
路由生成器代码:
@Component
public class SpringSecurityRoute extends RouteBuilder {
protected Logger logger = LoggerFactory.getLogger(SpringSecurityRoute.class);
@Override
public void configure() throws Exception {
from("direct:secure")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
logger.info("********************* Processing!");
}
});
}
}
测试类代码:
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringSecurityRouteTest {
private static Logger logger = LoggerFactory.getLogger(SpringSecurityRouteTest.class);
@Autowired
ProducerTemplate producerTemplate;
@Test
public void testRoute() {
logger.info("Starting test.");
producerTemplate.sendBody("direct:secure", "body");
}
}

问题是在运行测试之前没有初始化骆驼上下文。 如果在运行测试之前为骆驼上下文添加延迟以准备就绪,错误就会消失。 我将以下代码添加到测试类中,以便为骆驼上下文提供 5 秒的初始化时间。 不再抛出异常。 我注意到在没有增加延迟的情况下,不会打印表明路由已准备就绪的日志语句。
11:23:11.440 [CamelMainRunController] INFO o.a.camel.spring.SpringCamelContext - Route: route3 started and consuming from: direct://secure
添加到测试类的新代码:
private boolean isCamelContextInitialized = false;
@Before
public void initializeCamelContext() throws Exception {
if (!isCamelContextInitialized) {
logger.info("Waiting for Camel Context to become initialized.");
Thread.sleep(5000L);
}
}
更新测试类代码:
@RunWith(SpringRunner.class)
@SpringBootTest
public class SpringSecurityRouteTest {
private static Logger logger = LoggerFactory.getLogger(SpringSecurityRouteTest.class);
private boolean isCamelContextInitialized = false;
@Before
public void initializeCamelContext() throws Exception {
if (!isCamelContextInitialized) {
logger.info("Waiting for Camel Context to become initialized.");
Thread.sleep(5000L);
}
}
@Autowired
ProducerTemplate producerTemplate;
@Test
public void testRoute() {
logger.info("Starting test.");
producerTemplate.sendBody("direct:secure", "body");
}
}
我也不得不花很多时间来解决这个问题。 事实证明,我的RouteBuilder
没有被添加到CamelContext
因为我在RouteBuilder
类上没有@Component
注释。
我看到您在RouteBuilder
( SpringSecurityRoute
) 上包含了必要的@Component
注释,但是我无法从您的帖子中看出您的SpringSecurityRoute
是否通过组件扫描或其他类似方式添加到 Spring 上下文中. 一种确定的方法是在您对ProducerTemplate
调用 #sendBody 之前查看路由是否已添加到您的上下文中,如下所示:
@Test
public void testRoute() {
logger.info("Starting test.");
List<Route> routes = producerTemplate.getCamelContext().getRoutes();
// inspect list of routes in your debugger and see if your route is
// present within the camel context.
producerTemplate.sendBody("direct:secure", "body");
}
如果它不存在,则会导致您的帖子标题中提到的“端点上没有可用的消费者”错误。 因此,请确保您正在对包含您的路由的包进行组件扫描。
这是我如何将我的连接在一起:
路线建设者:
package com.example.camel.routes;
import org.apache.camel.builder.RouteBuilder;
import org.springframework.stereotype.Component;
@Component
public class HelloCamelRoute extends RouteBuilder {
public void configure() {
from("direct:sayHello").to("stream:out");
}
}
Spring Java 配置:
package com.example.camel.routes;
import org.apache.camel.spring.javaconfig.CamelConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan("com.example.camel.routes")
public class CamelConfig extends CamelConfiguration {
}
我将它包含在我的单元测试类中,如下所示:
package com.example.camel.routes;
import org.apache.camel.CamelContext;
import org.apache.camel.Produce;
import org.apache.camel.ProducerTemplate;
import org.apache.camel.Route;
import org.apache.camel.test.spring.CamelSpringRunner;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import java.util.List;
@RunWith(CamelSpringRunner.class)
@ContextConfiguration(classes = CamelConfig.class)
public class HelloCamelRouteIT {
@Autowired
protected CamelContext camelContext;
@Produce
protected ProducerTemplate producerTemplate;
@Test
public void doit() {
producerTemplate.sendBody("direct:sayHello", "Hello!");
}
}
你好!
当您在 Spring Boot 应用程序中测试骆驼时,还有其他跑步者可以使用。 看看https://camel.apache.org/manual/latest/spring-testing.html让你指向正确的方向。
