Apache Camel

个人理解

Camel相当于轻量级的ESB

from 定义源消息触发后续动作

process 触发后camel做的处理，比如分发，正则匹配下的分发

to 消息到哪里去

 

开启多个微服务，发送消息到camel，camel接收后，发送到下一个微服务

微服务应该是采用轮询的方式监听消息或数据，对于非高并发的场景，是可以接受的。

Running Examples

This section walks you through running the examples which are shipped with a binary distribution.

Before you start

First you need to Download a binary distribution.

To run the demos with maven, you need to download and install Apache Maven.

To test your Maven install, change directory to the examples directory and type:

mvn -v

You should see something like:

camel-rider:/tmp/camel/examples$ mvn -v

Maven version: 3.0.3

Running the examples in Maven

To run the first example using Maven, change directory to the example you want to run then issue the following command:

mvn exec:java

To run the other Spring-based examples such as the Spring Example, use the Camel Maven Plugin. For example:

cd camel-example-spring

mvn camel:run

Running the examples in your IDE

In each example you can run the main() from your IDE.

To create an IDEA project, run

mvn idea:idea

If you are an Eclipse user, run

mvn eclipse:eclipse

You should now be able to open the project(s) in your IDE and run any main() method you wish.
