flexmodel-codegen

Flexmodel的代码生成器模块，使用groovy脚本作为模板进行代码生成

1. 引入maven依赖

<dependency>
    <groupId>tech.wetech.flexmodel</groupId>
    <artifactId>flexmodel-codegen</artifactId>
    <version>LATEST</version>
</dependency>

2. 使用示例

继承类tech.wetech.flexmodel.ApiDefinitionGenerator

class ListApiDefinitionGenerator extends ApiDefinitionGenerator {

  @Override
  def generate(PrintWriter out, GenerationContext context) {
    def schemaName = context.getModelClass().getSchemaName()
    def modelName = context.getModelClass().getModelName()
    out.println "query MyListQuery( \$where: ${schemaName}_${modelName}_bool_exp) {"
    out.println "  ${schemaName}_list_${modelName}(where: \$where) {"
    context.getModelClass().getAllFields().each {
      if (!it.isRelationField()) {
        out.println "    ${it.fieldName}"
      }
    }
    out.println "  }"
    out.println "}"
  }
}

通过模板输出到目标对象中

ModelClass modelClass = GenerationTool.buildModelClass("com.example", dto.getDatasourceName(), entity);
GenerationContext generationContext = new GenerationContext();
generationContext.setModelClass(modelClass);
new ListApiDefinitionGenerator().generate(new PrintWriter(System.out), generationContext);

此为单文件的示例，tech.wetech.flexmodel.codegen.AbstractModelListGenerator实现多个模型输出到同一个文件中
