Question

基本上，我希望能够在JSON中发布对象并使用Java打印此对象的详细信息。

为了我想要（我必须）使用SPRING-BOOT和Camel

这是代表我的对象的类：

    public class Response {
    private long id;
    private String content;

    public Response(){

    }

    public Response(long id, String content) {
        this.id = id;
        this.content = content;
    }

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content){
        this.content = content;
    }

}

然后我有一个休息控制器：

    @RestController
public class BasicController {

    private static final String template = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    //Handle a get request 
    @RequestMapping("/test")
    public Response getResponse(@RequestParam(value="name", defaultValue="World") String name) {
        System.out.println("Handle by spring");
        return new Response(counter.incrementAndGet(),
                            String.format(template, name));
    }

    //Handle a post request
    @RequestMapping(value = "/post", method = RequestMethod.POST)
    public ResponseEntity<Response> update(@RequestBody Response rep) {

        if (rep != null) {
            rep.setContent("HANDLE BY SPRING");
        }  
        return new ResponseEntity<Response>(rep, HttpStatus.OK);
    }
}

使用此代码，我能够处理发布请求和打印细节，但我必须使用Camel。所以我尝试了以下内容：

1）我添加了一个bean conf

@SpringBootApplication
public class App 
{

    private static final String CAMEL_URL_MAPPING = "/camel/*";
    private static final String CAMEL_SERVLET_NAME = "CamelServlet";

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new CamelHttpTransportServlet(), CAMEL_URL_MAPPING);
        registration.setName(CAMEL_SERVLET_NAME);
        return registration;
    }
}

2）然后我创建了2条路线。

<?xml version="1.0" encoding="UTF-8"?>
<routes xmlns="http://camel.apache.org/schema/spring">
<!--      <route id="test"> -->
<!--          <from uri="timer://trigger"/> -->
<!--          <to uri="log:out"/> -->
<!--      </route> -->
     <route id="test2">
         <from uri="servlet:///test"/>
         <to uri="log:Handle by camel"/>
     </route>
 </routes>

有了这个，我就可以向骆驼提出请求了。但我不知道如何建立Spring和骆驼之间的联系。有没有办法用我的弹簧控制器处理请求然后调用骆驼路线？在同一个网址上..

您可以使用自动装配的producerTemplate来调用Camel路由。如果添加依赖项，将创建它：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-spring-boot</artifactId>
    <version>${camel.version}</version> <!-- use the same version as your Camel core version -->
</dependency>

有关详情，请参阅Camel文档here。

在你的情况下你会打电话给：

producerTemplate.sendBody...

使用Camel和Spring-boot构建REST应用程序
