在过去的几天中,我一直在进行Camel和REST DSL的基本演示,但是最终我遇到了这个问题。我对Spring Boot的魔力还很陌生,因此非常感谢任何反馈!
当我运行项目时,对于我的两条路线来说,一切似乎都可以正确启动。但是,当我尝试GET请求时,总是会返回404“未找到”消息。
我只有两个类在同一个程序包中,所以我不认为可见性会成为问题。我将项目创建为Spring Start Project,然后将其作为Spring Boot应用程序运行。日志显示两条路由已成功启动,并且Tomcat正在使用端口8080。上下文路径是在application.properties文件中专门配置的。
我的主要应用程序类:
打包com.example.demo;
import org.apache.camel.CamelContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@SpringBootApplication
@Configuration
@ComponentScan("com.example.demo")
public class DemoApplication {
@Autowired
CamelContext camelContext;
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
我的路由器类:
package com.example.demo;
import org.springframework.stereotype.Component;
import org.apache.camel.LoggingLevel;
import org.apache.camel.model.rest.RestBindingMode;
import org.apache.camel.builder.RouteBuilder;
@Component
public class DemoCamelRouter extends RouteBuilder {
@Override
public void configure() throws Exception {
restConfiguration().component("servlet")
.bindingMode(RestBindingMode.auto);
rest().get("/hello")
.to("direct:hello");
from("direct:hello")
.log(LoggingLevel.INFO, "Hello World")
.transform().simple("Hello World");
}
}
我的application.properties文件:
camel.springboot.main-run-controller=true
server.servlet.context-path=/demo
我正在使用http://localhost:8080/demo/hello
测试此服务这是我的Maven依赖项。
spring-boot-starter-web (managed:2.1.0.RELEASE)
spring-boot-starter-web-services (managed:2.1.0.RELEASE)
spring-boot-starter-test (managed:2.1.0.RELEASE)
camel-core: 2.22.2
camel-spring-boot-starter: 2.22.2
camel-servlet: 2.22.2
camel-http-common: 2.22.2
javax.servlet-api (managed:4.0.1)
最后,这是日志显示的内容。

答案 0 :(得分:2)
从Camel的2.19版本开始,CamelServlet默认设置为“ / camel”。这样您的网址就会变成:
http://localhost:8080/demo/camel/hello
更新:
使用camel-servlet
时,您还需要定义以下bean:
@Bean
public ServletRegistrationBean<Servlet> servletRegistrationBean() {
ServletRegistrationBean<Servlet> registration = new ServletRegistrationBean<>(new CamelHttpTransportServlet(), "/camel/*");
registration.setName("CamelServlet");
return registration;
}
或者应该添加camel-servlet
依赖而不是camel-servlet-starter
依赖
