identity-api-user

Branch	Build Status
master

This repository contains modules related to the identity user related REST apis. It can be compiled using JDK 8, JDK 11 or JDK 17.

Plugin to Generate the API Stubs

To generate stub, the swagger2cxf-maven-plugin is used.

We have done improvements to this plugin so that the stubs can be generated within a given package name. Therefore you can define multiple swagger files and deploy them in a single web application. To get the improvements locally, please follow the given steps.

1. Clone the repository https://github.com/IsuraD/swagger2cxf-maven-plugin

git clone https://github.com/IsuraD/swagger2cxf-maven-plugin.git

2. Checkout the branch swagger_to_jar

git checkout swagger_to_jar

3. Build the plugin

mvn clean install

Now, the locally built swagger2cxf plugin will be picked from the local .m2 repository when generating the stubs.

In this repository each user resource type is represented by a unique component. Hence, you need to create a new maven module for the resource type. Under this component the implementation of each major version will have a unique component along with version in it's name.

Implement a new API with a new swagger definition - version one

1. Include the API swagger definition in the given location of this maven project (identity-api-user). Suggested name for the file name of the API definition is <resource>.yaml

   +-- identity-api-user
   |   +-- components
   |       +-- org.wso2.carbon.identity.api.user.<resource>
   |           +-- org.wso2.carbon.identity.api.user.<resource>.<version>
   |               +-- src
   |                   +-- main
   |                       +-- resources
   |                           +--api.yaml
   |               +-- pom.xml
   |           +-- pom.xml
   

   Let's consider sample definition as challenge.yaml

    +-- identity-api-user
    |   +-- components
    |       +-- org.wso2.carbon.identity.api.user.challenge
    |           +-- org.wso2.carbon.identity.api.user.challenge.v1
    |               +-- src
    |                   +-- main
    |                       +-- resources
    |                           +--challenge.yaml
    |               +-- pom.xml
    |           +-- pom.xml
   

2. Include the given plugin to the pom.xml file of the module org.wso2.carbon.identity.api.user.<resource> .<version>

   <plugin>
       <groupId>org.wso2.maven.plugins</groupId>
       <artifactId>swagger2cxf-maven-plugin</artifactId>
       <version>1.0-SNAPSHOT</version>
       <configuration>
           <inputSpec>${project.basedir}/src/main/resources/<resource>.yaml</inputSpec>
       </configuration>
   </plugin>
   

   For our example:

   <plugin>
       <groupId>org.wso2.maven.plugins</groupId>
       <artifactId>swagger2cxf-maven-plugin</artifactId>
       <version>1.0-SNAPSHOT</version>
       <configuration>
           <inputSpec>${project.basedir}/src/main/resources/challenge.yaml</inputSpec>
       </configuration>
   </plugin>
   

   Note: Make sure to comment above plugin when you commit to remote as this plugin is not available in the maven repository.

3. Run the following command inside the module org.wso2.carbon.identity.api.user.<resource>.<version> to generate the stubs

   mvn swagger2cxf:generate
   

4. Comment out the plugin added for your API definition before committing to the git.

Implement a new version of an existing API - version one+plus

A new version is introduced only when a major version of API swagger definition is introduced.

1. Locate the correct parent module of the current API implementation. Create a new module with the new version and include the API swagger definition in the new module project . Suggested name for the file name of the API definition is .yaml

   +-- identity-api-user
   |   +-- components
   |       +-- org.wso2.carbon.identity.api.user.<resource>
   |           +-- org.wso2.carbon.identity.api.user.<resource>.<version>
   |               +-- src
   |                   +-- main
   |                       +-- resources
   |                           +--api.yaml
   |               +-- pom.xml
   |           +-- org.wso2.carbon.identity.api.user.<resource>.<version+1>
   |               +-- src
   |                   +-- main
   |                       +-- resources
   |                           +--api.yaml
   |               +-- pom.xml
   |           +-- pom.xml
   

   Let's consider sample definition as challenge.yaml

    +-- identity-api-user
    |   +-- components
    |       +-- org.wso2.carbon.identity.api.user.challenge
    |           +-- org.wso2.carbon.identity.api.user.challenge.v1
    |               +-- src
    |                   +-- main
    |                       +-- resources
    |                           +--challenge.yaml
    |               +-- pom.xml
    |           +-- org.wso2.carbon.identity.api.user.challenge.v2
    |               +-- src
    |                   +-- main
    |                       +-- resources
    |                           +--challenge.yaml
    |               +-- pom.xml
    |           +-- pom.xml
   

2. Include the given plugin to the pom.xml file of the module org.wso2.carbon.identity.api.user.<resource> .<version>

   <plugin>
       <groupId>org.wso2.maven.plugins</groupId>
       <artifactId>swagger2cxf-maven-plugin</artifactId>
       <version>1.0-SNAPSHOT</version>
       <configuration>
           <inputSpec>${project.basedir}/src/main/resources/<resource>.yaml</inputSpec>
       </configuration>
   </plugin>
   

   For our example:

   <plugin>
       <groupId>org.wso2.maven.plugins</groupId>
       <artifactId>swagger2cxf-maven-plugin</artifactId>
       <version>1.0-SNAPSHOT</version>
       <configuration>
           <inputSpec>${project.basedir}/src/main/resources/challenge.yaml</inputSpec>
       </configuration>
   </plugin>
   

3. Run the following command inside the module org.wso2.carbon.identity.api.user.<resource>.<version> to generate the stubs

   mvn swagger2cxf:generate
   

4. Comment out the plugin added for your API definition before committing to the git.

Implementing API definitions

Once you execute the above steps to generate the code it will generate set of java classes defining the Basic API definition.

├── src
│   ├── gen
│   │   └── java.org.wso2.carbon.identity.rest.api.user.<resource>.<version>
│   └── main
│       ├── java
│       │   └── java.org.wso2.carbon.identity.rest.api.user.<resource>.<version>.impl

In our example

├── src
│   ├── gen
│   │   └── java.org.wso2.carbon.identity.rest.api.user.challenge.v1
│   └── main
│       ├── java
│       │   └── java.org.wso2.carbon.identity.rest.api.user.challenge.v1.impl

You need to implement the functions of the classes under java.org.wso2.carbon.identity.rest.api.user.challenge.v1 .impl package to respond with desired output.

Inorder to improve re-usability of common implementations between versions, we encourage you to include a common component org.wso2.carbon.identity.api.user.<resource>.common for your resource type component as below.

   +-- identity-api-user
   |   +-- components
   |       +-- org.wso2.carbon.identity.api.user.<resource>
   |           +-- org.wso2.carbon.identity.api.user.<resource>.common
   |               +-- src
   |               +-- pom.xml
   |           +-- org.wso2.carbon.identity.api.user.<resource>.<version>
   |               +-- src
   |                   +-- main
   |                       +-- resources
   |                           +--api.yaml
   |               +-- pom.xml
   |           +-- org.wso2.carbon.identity.api.user.<resource>.<version+1>
   |               +-- src
   |                   +-- main
   |                       +-- resources
   |                           +--api.yaml
   |               +-- pom.xml
   |           +-- pom.xml
   

Let's consider sample resource

     +-- identity-api-user
     |   +-- components
     |       +-- org.wso2.carbon.identity.api.user.challenge
     |           +-- org.wso2.carbon.identity.api.user.challenge.common
     |               +-- src
     |               +-- pom.xml
     |           +-- org.wso2.carbon.identity.api.user.challenge.v1
     |               +-- src
     |                   +-- main
     |                       +-- resources
     |                           +--challenge.yaml
     |               +-- pom.xml
     |           +-- org.wso2.carbon.identity.api.user.challenge.v2
     |               +-- src
     |                   +-- main
     |                       +-- resources
     |                           +--challenge.yaml
     |               +-- pom.xml
     |           +-- pom.xml

You may add this common component in both the api version specific components as dependency and reuse.
