如何使用spring boot将参数传递给Apache Camel中的方法

import org.apache.camel.builder.RouteBuilder;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Component;

@SpringBootApplication
public class MyApp {

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

    @Component
    public class MyRoute extends RouteBuilder {

        @Override
        public void configure() throws Exception {
            from("direct:start")
                    .process(exchange -> {
                        // 从消息中获取参数
                        String param = exchange.getIn().getBody(String.class);
                        // 调用方法并处理参数
                        String result = processParam(param);
                        // 将处理结果设置为消息的主体
                        exchange.getIn().setBody(result);
                    })
                    .to("direct:end");
        }

        private String processParam(String param) {
            // 在这里处理参数并返回结果
            return "Processed: " + param;
        }
    }
}

import org.apache.camel.ProducerTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class MyController {

    @Autowired
    private ProducerTemplate producerTemplate;

    @GetMapping("/process/{param}")
    public String processParam(@PathVariable String param) {
        // 发送消息并调用路由
        String result = producerTemplate.requestBody("direct:start", param, String.class);
        return result;
    }
}
