JarCastingThis plugin is a wrapper around kongchen's swagger-maven-plugin
This is a fork of gigaSproule/swagger-gradle-plugin that uses swaggerSpec instead of swagger for the specification extension. This is done to avoid conflicts with the swagger-codegen-plugin which uses the same extension name.
This enables your Swagger-annotated project to generate Swagger specs and customizable, templated static documents during the gradle build phase. Unlike swagger-core, swagger-gradle-plugin does not actively serve the spec with the rest of the application; it generates the spec as a build artifact to be used in downstream Swagger tooling.
Features
- Supports Swagger Spec 2.0
- Supports SpringMvc & JAX-RS
- Use Handlebars as template to customize the static document.
Usage
Import the plugin in your project by adding following configuration:
swaggerSpec {
apiSource {
...
}
}
One apiSource can be considered as a version of APIs of your service.
You can specify several apiSources. Generally, one is enough.
Configuration for apiSource
| name | description |
|---|---|
springmvc |
Tell the plugin your project is a JAX-RS(false) or a SpringMvc(true) project |
locations required |
Classes containing Swagger's annotation @Api, or packages containing those classes can be configured here, using ; as the delimiter. |
schemes |
The transfer protocol of the API. Values MUST be from the list: "http", "https", "ws", "wss". |
host |
The host (name or ip) serving the API. This MUST be the host only and does not include the scheme nor sub-paths. It MAY include a port. The host does not support path templating. |
basePath |
The base path on which the API is served, which is relative to the host. The value MUST start with a leading slash (/). The basePath does not support path templating. |
descriptionFile |
A Path to file with description to be set to Swagger Spec 2.0's info Object |
info required |
The basic information of the api, using same definition as Swagger Spec 2.0's info Object |
securityDefinitions |
You can put your security definitions here, see more details below |
templatePath |
The path of a handlebars template file, see more details below. |
outputPath |
The path of the generated static document, not existed parent directories will be created. If you don't want to generate a static document, just don't set it. |
outputFormats |
The format types of the generated swagger spec. Valid values are json, yaml or both json,yaml. The json format is default. |
swaggerDirectory |
The directory of generated swagger.json file. If null, no swagger.json will be generated. |
swaggerApiReader |
If not null, the value should be a full name of the class implementing com.github.kongchen.swagger.docgen.reader.ClassSwaggerReader. This allows you to flexibly implement/override the reader's implementation. Default is com.github.kongchen.swagger.docgen.reader.JaxrsReader |
attachSwaggerArtifact |
If enabled, the generated swagger.json file will be attached as a gradle artifact. The swaggerDirectory's name will be used as an artifact classifier. Default is false. |
modelSubstitute |
The model substitute file's path, see more details below |
typesToSkip |
Nodes of class names to explicitly skip during parameter processing. More details below |
apiModelPropertyAccessExclusionsList |
Allows the exclusion of specified @ApiModelProperty fields. This can be used to hide certain model properties from the swagger spec. More details below |
jsonExampleValues |
If true, all example values in @ApiModelProperty will be handled as json raw values. This is useful for creating valid examples in the generated json for all property types, including non-string ones. |
skipSwaggerGeneration |
If true, swagger generation will be skipped. Default is false. |
Template File
If you'd like to generate a template-driven static document, such as markdown or HTML documentation, you'll need to specify a handlebars template file in templatePath. The value for templatePath supports 2 kinds of path:
-
Resource in classpath. You should specify a resource path with a classpath: prefix. e.g:
classpath:/markdown.hbsclasspath:/templates/hello.html
-
Local file's absolute path. e.g:
${project.rootDir}/src/main/resources/markdown.hbs${project.rootDir}/src/main/resources/template/hello.html
There's a standalone project for the template files, fetch them and customize it for your own project.
Security Definitions
There're 3 types of security definitions according to Swagger Spec: basic, apiKey and oauth2.
You can define multi definitions here, but you should fully follow the spec.
You can define a basic definition like this:
securityDefinition {
name = 'MyBasicAuth'
type = 'basic'
}
or define several definitions in a json file and specify the json path like this:
securityDefinition {
json = '/securityDefinition.json'
}
The file will be read by getClass().getResourceAsStream, so please note the path you configured.
The securityDefinition.json file should also follow the spec, one sample file like this:
{
"api_key": {
"type": "apiKey",
"name": "api_key",
"in": "header"
},
"petstore_auth": {
"type": "oauth2",
"authorizationUrl": "http://swagger.io/api/oauth/dialog",
"flow": "implicit",
"scopes": {
"write:pets": "modify pets in your account",
"read:pets": "read your pets"
}
}
}
Model Substitution
Throughout the course of working with Swagger, you may find that you need to substitute non-primitive objects for primitive objects. This is called model substituion, and it is supported by swagger-gradle-plugin. In order to configure model substitution, you'll need to create a model substitute file. This file is a simple text file containing n lines, where each line tells swagger-gradle-plugin to substitutes a model class with the supplied substitute. These two classes should be seperated by a colone (:).
Sample model substitution
com.foo.bar.PetName : java.lang.String
The above model substitution configuration would tell the plugin to substitute com.foo.bar.PetName with java.lang.String. As a result, the generated swagger.json would look like this ...
"definitions" : {
"Pet" : {
"properties" : {
...
"petName" : {
"type" : "string"
}
...
}
}
... instead of like this:
"definitions" : {
"Pet" : {
"properties" : {
...
"petName" : {
"$ref" : "#/definitions/PetName"
}
...
}
}
The model substitution file will be read by getClass().getResourceAsStream, so please note the path you configured.
Skipping Types During Processing with typesToSkip
You can instruct swagger-gradle-plugin to skip processing the parameters of certain types by adding the following to your build.gradle: // TODO: Not fully supported yet
typesToSkip = [
'com.foobar.skipper.SkipThisClassPlease',
'com.foobar.skipper.AlsoSkipThisClassPlease'
}
Excluding certain @ApiModelProperty items
If you'd like to exclude certain @ApiModelPropertys based on their access values, you may do so by adding the following as a child node of apiSource in your build.gradle:
apiModelPropertyAccessExclusionsList = [
'secret-property'
]
The above setting would prevent internalThing from appearing in the swagger spec output, given this annotated model:
...
@ApiModelProperty(name = "internalThing", access = "secret-property")
public String getInternalThing() {
return internalThing;
}
...
Note: In order to use apiModelPropertyAccessExclusionsList, you must specify both the name and access fields of the property you wish to exclude.
Generating the swagger documentation
To generate the swagger documentation, you need to run ./gradlw generateSwaggerDocument.
N.B In previous versions (< 0.1.0) the task was swagger, but this caused a conflict with another plugin, swagger-codegen, (issue #8).
Install/Deploy swagger.json
You can instruct swagger-gradle-plugin to deploy the generated swagger.json by adding the following to your build.gradle:
swaggerDirectory = '${project.rootDir}/swagger-ui'
attachSwaggerArtifact = true
The above setting attaches the generated file to Gradle for install/deploy purpose with swagger-uias classifier and json as type
