Camel的direct，Bean测试

//处理Bean

    public TestBean(){

    public String showBody(Exchange exchange) throws Exception {
        System.out.println("\r\n\r\n");
        Message in=exchange.getIn();
        byte []bs=read((ByteArrayInputStream)in.getBody());

    /*
    --> parse(request) //got head and body
    --> response=route(request) //call remote system by head[system_id][service_id][method_id]
    --> write_response(response)

    配置文件名为：system_id_value.ini, 如：opg.ini

    发起方：在head提供 system_id, service_id,method_id 三个参数,
         esb在收到请求后，将请求转发到配置的地址
        system_url= //远程的接口地址
        uri_${service_id}_${method_id}= //远程方法uri, 和 system_url 组成完整的接口url
        head_dealer=
        body_dealer=

    system_id=opg
    service_url=http://127.0.0.1/opg //rmi, soa ,
    method_uri=head    //或者 url即将 /service_id/method_id 加到 service_url 后面
    request_type=json //或者 map , 请求的数据格式：目标需要的请求数据格式 json 或 httpRequest的 Map
    response_type=json //text, 返回的数据格式

    service_id

camel-config.xml 主要内容：

用浏览器访问： http://127.0.0.1:8080/esb/camel/time 可获得系统的时间。

本测试主要体验了： direct 和 bean , exchange 的基本用法。

下面是用 karaf 过程的一些记录：

//注册 camel feature 到 karaf
           feature:repo-add mvn:org.apache.camel.karaf/apache-camel/2.17.1/xml/features

      //安装 camel 到 karaf
           feature:install camel

           feature:install -v camel-blueprint

      //查看camel运行状态
           feature:list | grep camel
      //查看 repo
           feature:repo-list
      //加 camel-blueprint
           feature:install camel-blueprint

      mvn compile
      mvn install / mv clean install

      bundle:install mvn:com.packt.camel/chapter3/1.0-SNAPSHOT
    bundle:list
    bundle:start id
    bundle:stop id
    camel:context-list
    bundle:uninstall chapter3

    feature:install camel-jetty
