Introducci\u00f3n<\/h1>\r\n

Mule es ESB (Enterprise Service Bus) Se usa para enviar\/recibir mensajes heterog\u00e9neos entre diferentes productos\/consumidores.

Admite muchos componentes de transporte y servicio como JMS, SOAP, JBI, BPEL, EJB, AS\/400, HTTP, JDBC, TCP, UDP, SMTP, FILE, FTP y m\u00e1s.

Como en Internet el idioma padre es HTTP vamos a ver c\u00f3mo hacer logging de las peticiones y respuestas HTTP que pasan por mule.<\/p>\r\n

<\/p>\r\n

Log de HTTP con log4j<\/h1>\r\n

Vamos a suponer un caso sencillo, done una petici\u00f3n HTTP entrante produce una HTTP saliente.<\/p>\r\n

En mule el flujo podr\u00eda ser as\u00ed:<\/p>\r\n

\"ConsumeRestAPI<\/p>\r\n

No es el objetivo de esta entrada dar una clase de mule, basta decir que las bolas azules unas es un “HTTP Listener<\/strong>” que escucha los mensajes enviados a mule y un “HTTP Request<\/strong>” que se encarga de enviar peticiones HTTP desde mule a otra aplicaci\u00f3n. Ambos compoenntes, necesitan de otro que no es gr\u00e1fico que se llama “Configuration”.<\/p>\r\n

Voy a suponer el caso que tengo una configuraci\u00f3n para el listener que se llama HTTP_Listener_config<\/strong> y otra para el Request que se llama a su vez HTTP_Request_configuration<\/strong>. En este caso el fichero log4j.xml<\/strong> para observar un fichero de log y un log por consola ser\u00eda algo as\u00ed:<\/p>\r\n

    <!--These are some of the loggers you can enable. 
        There are several more you can find in the documentation. 
        Besides this log4j configuration, you can also use Java VM environment variables
        to enable other logs like network (-Djavax.net.debug=ssl or all) and 
        Garbage Collector (-XX:+PrintGC). These will be append to the console, so you will 
        see them in the mule_ee.log file. -->
