swagger2文档的步骤

传统方法

　　a: 创建web工程

　　b： 配置springmvc web.xml

　　c： 编写controller

　　d ：部署tomact

springboot

　　1 创建springboot 工程 必须继承spring-boot-stater-parent

　　导依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.7.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.7.0</version>
</dependency>

配置文件Config

import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2 //开启在线文档
public class SwaggerConfig {
    //声明api 文档属性 构建器
    private ApiInfo apiInfo(){
        return new ApiInfoBuilder()
                .title("springboot中使用在线文档构建RestFul风格Apis")
                .description("哈哈")
                .termsOfServiceUrl("http://www.baidu.com/")
                .contact("0708java")
                .version("2.0")
                .build();

    }
    //配置核心配置信息
    public Docket creatRestApi(){
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.offcn.springbootdemo.controller"))
                .paths(PathSelectors.any())
                .build();
    }
}

　　2 编写controller

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/work")
public class WorkController {

    @RequestMapping(value = "/first")
    public String getList(@RequestParam("id") Integer id){

        return "hahahah"+id;
    }
}

　　3 主启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootdemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootdemoApplication.class, args);
    }

}

　　4 启动main
