  • Newbie Question: Using Groovy on file sample

    I am a newbie to Spring Integration and Love everything I have seen so far.

    I have been experimenting with the sample apps and making minor modifications to make sure I understand them.

    I am working with the file sample. I would like to implement the org.springframework.integration.sampes.filecopy.Ha ndler in Groovy.

    When I test it by running TextFileCopyTest, I receive the following stack trace:

    (Any Thoughts? Does someone have an example using Spring Integration and Groovy this way from the Samples?)

    Could you please post your configuration so we can get some context as to how you are doing it?

    Comment


    • #3
      One important point this raises is that we need to add a Groovy sample, so I just created a task in JIRA for that: https://jira.springsource.org/browse/INT-1888

      In the meantime, you can see a few examples of using Groovy scripts from within Spring Integration components in these test configurations (see the XML files): http://git.springsource.org/spring-i.../groovy/config

      Hope that helps.

        Config Info

        Mark and Oleg,

        Thanks for the speedy reply, . . . I will look at the examples and see if I get some insights.

        Here is my config file and GroovyHandler:

        ==============================

        package org.springframework.integration.samples.filecopy

        class GroovyHandler {

        public String handleString(String input) {
        System.out.println("Copying text: " + input);
        return input.toUpperCase();
        }

        }

          When you look at those samples (in the tests), you will see that in Spring Integration you can use Groovy as *just a Script* instead of a class.

          However, if you do want a "bean" that is actually Groovy-based, then just have a look at the core Spring support for that as described here: http://static.springsource.org/sprin...e-beans-groovy

            Still having an issue

            I 've tried to simplify the example and have an attachment of the eclipse project.

            In order to simplify the process I switched from a service activator to an transformer with an inline groovy script.

            Note it is using the loadConfig in the same directory as the test, not the resource version.

            When I run TextFileCopyTest, I receive the following error and stack trace:

            Cannot resolve the name 'integration:innerPollerType' to a(n) 'type definition' component.

            Any help would be appreciated.

              Ok, first change your POM to use 2.0.2.BUILD-SNAPSHOT. The 'innerPollerType' was removed https://jira.springsource.org/browse/INT-1715.
              Let us now. I'll try to run it in a bit.

                  Same Error

                  Ok, update pom.xml to the 2.0.4.BUILD-SNAPSHOT

                  <spring.integration.version>2.0.4.BUILD-SNAPSHOT</spring.integration.version>

                  Same error.

                  could it be that

                  http://www.springframework.org/schem...ntegration.xsd

                  still references innerPollerType?

                  Should we get XSD from somewhere else?

                    It seems like its picking up a wrong schema somehow.
                    Coudl you try to change it to http://www.springframework.org/schem...ration-2.0.xsd

                        Can you also verify that the 2.0.4.BUILD-SNAPSHOT version is the *only* one on your classpath?

                          Hmm

                          Let me try your sample. I'll let you know.

                            Got something working

                            Here is what I had to do to get things going:

                            1) Download spring-integration-2.0.xsd to local drive
                            2) Change xsd innerPollerType references to BasePollerType
                            3) Change loadConfig.xml schemaLocation reference to use local copy
                            4) remove poller reference and use global poller

                            <poller id="poller" default="true" >
                            <interval-trigger interval="100"/>
                            </poller>

                            5) modify pom.xml to include spring-integration-groovy 2.0.4.BUILD-SNAPSHOT Dependency

                            Step 2 and 4 seems to be the primary issues.

                            I am attaching the changed xsd and the eclipse project so that you can see and a sample data file

                              You should never have to do any of that. The XSD is loaded from the classpath (not the publicly available URL). Did you check to be sure that you don't have multiple versions of Spring Integration on your classpath?
