Swagger2

Swagger文档基础配置

@Configuration //标记这是一个配置
@EnableSwagger2 //启用Swagger2
public class SwaggerConfig {
    // 创建接口文档的具体信息，会显示在接口文档页面中
    public ApiInfo createApiInfo(){
        return new ApiInfoBuilder()
                // 文档标题
                .title("2022接口文档")

                .description("Swaager使用文档")
                // 联系人信息
                .contact(new Contact("Stars","","xx@QQ.com"))
                // 版本
                .version("V1.0")
                .license("Stars_Yu")
                .build();
    }
@Bean(value = "dockerBean")//IOC容器  创建Docket存入容器，Docket代表一个接口文档
public Docket dockerBean(){
        Docket docket =  new Docket(DocumentationType.SWAGGER_2)
                // 创建接口文档的具体信息
                .apiInfo(createApiInfo())
                .groupName("基础平台")
                // 创建选择器，控制哪些接口被加入文档
                .select()
                // 指定@ApiOperation标注的接口被加入文档
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .build();
        return  docket;
    }
}

 

Mybatis_Plus

配置Mappger基础方法

其中BaseMapper已存在增删改查等基础方法

通过Service中调用的方法进行数据查询

调用Service中方法

自定义接口

自定义方法 通过对应xml进行具体实现

自定义方法的具体实现
