由于骆驼上下文引起的错误，我无法运行我的程序，我应该怎么做才能解决这个问题?

Question

我在这里要做的是通过camel apache创建一个缩放会议。每当我运行程序时，我总是得到错误，导致错误的行是当我启动骆驼上下文c.start()时下面是我运行的代码:

package com.example.demo;
import com.google.gson.Gson;
import com.google.gson.JsonObject;
import org.apache.camel.*;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.model.dataformat.JsonLibrary;
import static org.springframework.http.converter.json.Jackson2ObjectMapperBuilder.json;
public class Test {
private String token = "sample token";
public static void main(String[] args) throws Exception {
CamelContext c = new DefaultCamelContext();
settings set = new settings(true, true, false,
false, true,"voip","cloud");
recurrence rec = new recurrence(1,1);
c.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start")
.process(exchange -> exchange.getIn().setBody(new ZoomSetting(
"Testing zoom api",
2,
"2022-05-09T14: 00: 00",
45,
"America/New_York",
"testing",
rec,
set
)))
.marshal().json(JsonLibrary.Gson)
.setHeader(Exchange.HTTP_METHOD, constant("POST"))
.setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
.setHeader("Authorization", simple("Bearer"+ token))
.to("https://api.zoom.us/v2/users/me/meetings")
.process(exchange -> log.info("The response code is: {}", exchange.getIn().getHeader(Exchange.HTTP_RESPONSE_CODE)));
}
});
c.start();
}
}

我试图在pom.xml文件中包含依赖项，但这并没有真正起作用。以下是我在pom.xml中包含的依赖项:

如果你想使用main方法运行camel，你应该使用camel-main它用于运行独立的驼峰应用程序。你要做的是将camel作为独立应用程序运行，但使用camel-spring-boot依赖项。

您可以使用maven原型camel- prototype -main生成新的独立驼峰应用程序项目，并将其作为如何设置项目的参考。

mvn archetype:generate -DarchetypeGroupId="org.apache.camel.archetypes" -DarchetypeArtifactId="camel-archetype-main" -DarchetypeVersion="3.14.3"

如果你想使用spring-framework和spring-boot要跑骆驼，可以使用camel- prototype -spring-boot原型，用于生成示例驼峰弹簧靴项目。我建议在使用camel之前先熟悉Spring-framework和Spring-boot的基础知识，以避免不必要的混淆。

mvn archetype:generate -DarchetypeGroupId="org.apache.camel.archetypes" -DarchetypeArtifactId="camel-archetype-spring-boot" -DarchetypeVersion="3.14.3"

• Camel - Archetypes
• Camel - main
• 骆驼-弹簧靴
