提问by gstackoverflow
I have the following route definition:
我有以下路线定义：
@Component
public class CamelRoutes extends RouteBuilder {
@Override
public void configure() throws Exception {
from("seda:second")
.bean("helloWorld?method=smth")
.process(exchange -> {
System.out.println("Message:" + exchange.getIn().getBody());
})
.log("body:${body}");
and following bean:
和以下豆：
public static class HelloWorld {
public void execute(String str){
System.out.println("HelloWorld#execute: " + str);
}
public void smth(String str){
System.out.println("HelloWorld#smth: " + str);
}
}
But application doesn't start.

但是应用程序没有启动。

But I see:
但我看到：
from("direct:a").bean(ClassName.class , "methodName").to("direct:b");
when application starts.
应用程序启动时。
I checked - method marked as @Beanis invoked.
我检查了 - 标记为的方法@Bean被调用。
采纳答案by gstackoverflow
this works:
这有效：
from("direct:a").bean("registeredClassName","methodName").to("direct:b");
// this registered named is the name that you give to spring annotations like
//@Component , @Configuration , @Service , @Controller , @Bean etc...
// If you are using Camel stand alone then registeredClassName is the name that
// you gave to camel's registry.
//For example:
SimpleRegistry simpleRegistry = new SimpleRegistry(); // this class is just a mapper
simpleRegistry.put("registeredClassName",new ClassName());
CamelContext camelContext = new DefaultCamelContext(simpleRegistry);
回答by Od Chan
The way you give the class name and method to "bean" is wrong!
If you wanna use beanthen these are acceptable ways for how to work with it:
你给“bean”类名和方法的方式是错误的！如果您想使用，bean那么这些是可以接受的使用方式：
// In Spring Boot
@Autowired
private ClassName instanceOfClassName;
from("direct:a").bean(instanceOfClassName , "methodName").to("direct:b");
from("direct:a").to("bean:registeredClassName?method=methodName").to("direct:b");
// remember no parenthesis () for methodName
from("direct:a").to("bean:FullyQualifiedClassName?method=Name").to("direct:b");
And this is the right way for using class and method together like the way you went through:
这是将类和方法一起使用的正确方法，就像您所经历的那样：
from("direct:start").bean("registeredClassName","methodName(${body},${header.customerId},${header.customerType}");
Also this is another way of invoking bean and its' method although it is a little advance and you need to know what is Simple-Language.
这也是调用 bean 及其方法的另一种方式，尽管它有点先进，您需要知道什么是简单语言。
##代码##That's all :))
就这样 ：））
回答by cristianoms
As you're already using Spring, why not annotate your bean with @Componentand use an autowired instance inside your route?
由于您已经在使用 Spring，为什么不在@Component您的路由中注释您的 bean并使用自动装配的实例呢？
