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

问题描述

我正在使用Camel的spring DSL构建路由，并且正在使用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，我是这样做的:

<bean ref="myPojoBeanProcessor"/>

其中，"myPojoBeanProcessor"在我的Spring上下文中被定义为bean.

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

然后，我切换到:

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

我认为Java DSL相当于:

The Java DSL equivalent would be, I think:

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

我想知道在后面的方法中，是否将在每个请求中实例化一个bean对象，还是将bean实例缓存并用作一个单例对象(如spring中的默认值).

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Google中找到答案.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

为什么不尝试一下:)

Camel将使用默认的no-arg构造函数一次创建一个实例，并缓存该实例，例如其单例作用域.

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