3 Quick Start

3.1 Build tool and plugins from source

Build environment requirements

# Get the latest source code for toolkit from github
$ git clone https://github.com/apache/servicecomb-toolkit.git
$ cd toolkit

# Build package
$ mvn clean install

3.2 Use the toolkit-maven-plugin plugin

3.2.1 configuration

Configured in the pom file of the maven project

<plugin>
    <groupId>org.apache.servicecomb.toolkit</groupId>
    <artifactId>toolkit-maven-plugin</artifactId>
    <version>0.3.0-SNAPSHOT</version>
    <configuration>
        <!-- Set to 'code' to resolve the current project. Set to 'contract' to resolve the contract file for the specified path.If not set, the default is 'code' -->
        <sourceType>code</sourceType>
        <!-- The type of the contract file is generated. If it is not set, the default is 'yaml' -->
        <contractFileType>yaml</contractFileType>
        <!-- The type of the generated document. If not set, the default is 'html' -->
        <documentType>html</documentType>
        <!-- The root directory to save microservice project,contract file and document. If it is not set, the default is the 'target' under the directory where the command is run -->
        <outputDirectory>./target</outputDirectory>
        <!-- Input contract file path. Valid when sourceType is set to 'contract', must be set -->
        <contractLocation>./contract</contractLocation>
        <!-- Checked contract file path. Valid when sourceType is set to 'contract', must be set -->
        <sourceContractPath>./target/contract</sourceContractPath>
        <!-- Sample contract file path, must be set -->
        <destinationContractPath>./contract</destinationContractPath>
        <!-- Generated microservice project configuration -->
        <service>
            <!-- Microservice type,can generated 'provider/consumer/all',the default is 'all' -->
            <serviceType>all</serviceType>
            <!-- Microservice project 'groupid',optional,the default is 'domain.orgnization.project' -->
            <groupId>domain.orgnization.project</groupId>
            <!-- Microservice project 'artifactId',optional,the default is 'sample' -->
            <artifactId>sample</artifactId>
            <!-- Microservice project 'artifactVersion',optional,the default is '0.1.0-SNAPSHOT' -->
            <artifactVersion>0.1.0-SNAPSHOT</artifactVersion>
            <!-- Microservice project 'packageName',optional,the default is 'domain.orgnization.project.sample' -->
            <packageName>domain.orgnization.project.sample</packageName>
        </service>
        <!-- Specify additional attribute values that can be referenced by the mustache template.Only used when plugin goal is generate -->
        <additionalProperties>
            <prop1>value</prop1>
            <prop2>value</prop2>
            ...
            <propN>value</propN>
        </additionalProperties>
    </configuration>
</plugin>

3.2.2 Command

# Generating contract, document and microservice project
mvn toolkit:generate

# Verify code and contract consistency
mvn toolkit:verify

3.2.2.1 Extract the microservice project, OpenAPI contract file and document from the code

Configuration(use default configuration if not set <configuration>)

example

<plugin>
    <groupId>org.apache.servicecomb.toolkit</groupId>
    <artifactId>toolkit-maven-plugin</artifactId>
    <version>0.3.0-SNAPSHOT</version>
    <configuration>
        <!-- Set to 'code' to resolve the current project. Set to 'contract' to resolve the contract file for the specified path.If not set, the default is 'code' -->
        <sourceType>code</sourceType>
        <!-- The root directory to save contract file and document. If it is not set, the default is the 'target' under the directory where the command is run -->
        <outputDirectory>./target</outputDirectory>
        <!-- Generated microservice project configuration -->
        <service>
            <!-- Microservice type,can generated 'provider/consumer/all',the default is 'all' -->
            <serviceType>all</serviceType>
        </service>
    </configuration>
</plugin>

Run in shell

mvn toolkit:generate

When generating contracts from code,support for identifying restful interfaces written by the following annotations (class level)

RestController, RestSchema, RpcSchema, RequestMapping

When generating contracts from code,the restful interface method access modifier must be specified as public

3.2.2.2 Generate the microservice project and document from contract

Configuration(use default configuration if not set <configuration>)

example

<plugin>
    <groupId>org.apache.servicecomb.toolkit</groupId>
    <artifactId>toolkit-maven-plugin</artifactId>
    <version>0.3.0-SNAPSHOT</version>
    <configuration>
        <!-- Set to 'code' to resolve the current project. Set to 'contract' to resolve the contract file for the specified path.If not set, the default is 'code' -->
        <sourceType>contract</sourceType>
        <!-- The root directory to save contract file and document. If it is not set, the default is the 'target' under the directory where the command is run -->
        <outputDirectory>./target</outputDirectory>
        <!-- Input contract file path. Valid when sourceType is set to 'contract', must be set -->
        <contractLocation>./contract</contractLocation>
        <!-- Generated microservice project configuration -->
        <service>
            <!-- Microservice type,can generated 'provider/consumer/all',the default is 'all' -->
            <serviceType>provider</serviceType>
        </service>
    </configuration>
</plugin>

Run in shell

mvn toolkit:generate

        <destinationContractPath>./contract</destinationContractPath>
    </configuration>
