Apache Camel POJO Bean Processor Singleton 还是 Prototype? [英] Apache Camel POJO Bean Processor Singleton or Prototype?

问题描述

我使用 Camel 的 spring DSL 来构建路由，我使用我的 POJO bean 作为处理器.

I'm using Camel's spring DSL to build routes and I'm using my POJO bean as a processor.

最初，我这样做:

<bean ref="myPojoBeanProcessor"/>

其中，myPojoBeanProcessor"在我的 spring 上下文中被定义为一个 bean.

where, 'myPojoBeanProcessor' was defined as a bean in my spring context.

然后，我切换到:

<bean beanType="com.mycompany.transformation.MyPojoBeanProcessor"/>

Java DSL 等价物，我认为:

The Java DSL equivalent would be, I think:

from("xxx").bean(MyPojoBeanProcessor.class).xxx

我想知道使用后一种方法，是否会在每个请求中实例化 bean 对象，或者是否会缓存 bean 实例并将其用作单例(如 spring 中的默认设置).

I'm wondering if with the later approach, a bean object would be instantiated with every request or would the bean instance be cached and used as a singleton (like the default in spring).

我无法在骆驼文档或谷歌上找到答案.有人知道这个问题的答案吗?

I was unable to find an answer in the camel documentation or on google. Does anyone know the answer to this question?

推荐答案

为什么不试试看 :)

Camel 将使用默认的无参数构造函数一次创建一个实例，并缓存该实例，例如它的单例范围.

Camel will create an instance one time using the default no-arg constructor, and cache the instance, eg its singleton scoped.
