Generator

根据GraphQL Schema生成Java代码及DgraphSchema

参考 graphql-example

使用

1. 添加maven依赖

最新版本为 1.6.0-SNAPSHOT

<dependency>
    <groupId>io.github.wangyuheng</groupId>
    <artifactId>arc-generator</artifactId>
    <version>1.6.0-SNAPSHOT</version>
</dependency>

2. 添加graphql schema文件

新建文件 test/resources/graphql/schema.graphqls

Example

scalar DateTime

schema{
    query: Query,
    mutation: Mutation
}

type Query{
    project(
        id: String
    ): Project
}

type Mutation{
    createProject(
        payload: ProjectInput
    ): Project
}
type Project{
    id: String!
    name: String!
    description: String!
    createTime: DateTime!
    milestone(
        id: String
    ): Milestone
    milestones: [Milestone]
}

type Milestone{
    id: String!
    name: String!
    description: String!
    version: String!
    createTime: DateTime!
    endTime: DateTime
}

input ProjectInput{
    name: String!
    description: String!
    dsl: String!
    vendorBranches: [String!]!
}

3. 新建配置文件

新建配置文件， 默认路径为 resources:arc-generator.json 可以通过plugin配置修改

{
  "basePackage": "io.github.wangyuheng.arcgeneratorexample",
  "dropAll": false,
  "genStrategies": [
    {
      "codeGenOperation": "SKIP",
      "codeGenType": "REPO"
    },
    {
      "codeGenOperation": "OVERRIDE",
      "codeGenType": "API"
    }
  ],
  "ignoreJavaFileNames": [
    "User"
  ],
  "dgraphPath": "dgraph/schema.dgraph"
}

4. 执行maven命令

mvn arc:generate

可以通过参数-Dtarget决定生成java or dgraph schema 如

mvn arc:generate -Dtarget=java

运行后会在根据配置在指定目录生成相关业务代码

其他

1. 内置directive

• directive @Action on FIELD_DEFINITION 区分field是字段还是方法
