Introduction

Data Import Converter Storage.

Provides PostgreSQL based storage to complement the data import module. Written in Java, using the raml-module-builder and uses Maven as its build system.

Compiling

   mvn install

See that it says "BUILD SUCCESS" near the end.

Docker

Build the docker container with:

   docker build -t mod-data-import-converter-storage .

Test that it runs with:

   docker run -t -i -p 8081:8081 mod-data-import-converter-storage

Installing the module

Follow the guide of Deploying Modules sections of the Okapi Guide and Reference, which describe the process in detail.

First of all you need a running Okapi instance. (Note that specifying an explicit 'okapiurl' might be needed.)

   cd .../okapi
   java -jar okapi-core/target/okapi-core-fat.jar dev

We need to declare the module to Okapi:

curl -w '\n' -X POST -D -   \
   -H "Content-type: application/json"   \
   -d @target/ModuleDescriptor.json \
   http://localhost:9130/_/proxy/modules

That ModuleDescriptor tells Okapi what the module is called, what services it provides, and how to deploy it.

Deploying the module

Next we need to deploy the module. There is a deployment descriptor in target/DeploymentDescriptor.json. It tells Okapi to start the module on 'localhost'.

Deploy it via Okapi discovery:

curl -w '\n' -D - -s \
  -X POST \
  -H "Content-type: application/json" \
  -d @target/DeploymentDescriptor.json  \
  http://localhost:9130/_/discovery/modules

Then we need to enable the module for the tenant:

curl -w '\n' -X POST -D -   \
    -H "Content-type: application/json"   \
    -d @target/TenantModuleDescriptor.json \
    http://localhost:9130/_/proxy/tenants/<tenant_name>/modules

REST Client

Provides RMB generated Client to call the module's endpoints. The Client is packaged into the lightweight jar.

Maven dependency

    <dependency>
      <groupId>org.folio</groupId>
      <artifactId>mod-data-import-converter-storage-client</artifactId>
      <version>x.y.z</version>
      <type>jar</type>
    </dependency>

Where x.y.z - version of mod-data-import-converter-storage.

Usage

ConverterStorageClient is generated by RMB and provides methods for all endpoints described in the RAML file

    // create client object with okapi url, tenant id and token
    ConverterStorageClient client = new ConverterStorageClient("localhost", "diku", "token");

Clients methods work with RMB generated data classes based on json schemas. mod-data-import-converter-storage-client jar contains only generated by RMB DTOs and clients.

Example of sending a request to the mod-data-import-converter-storage

    // send request to mod-data-import-converter-storage
    client.getConverterStorage(response->{
      // processing response
      if (response.statusCode() == 200){
        System.out.println("Call is successful");
      }
    });
