springboot集成swagger

　　Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。

作用：

1. 接口的文档在线自动生成。
2. 功能测试。

1、配置pom.xml

       <!-- swagger -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

        <!-- jackson相关依赖 -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.5.4</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml</groupId>
            <artifactId>classmate</artifactId>
            <version>1.2.0</version>
        </dependency>

2、使用注解来进行启动swagger

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

/**
 * @author Administrator
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                //.apis(RequestHandlerSelectors.basePackage("com.template.controller"))
                .apis(RequestHandlerSelectors.withClassAnnotation(RestController.class))
                .paths(PathSelectors.any())
                .build();
//        return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).build();
    }

    /**
     * 构建 api文档的详细信息函数,注意这里的注解引用的是哪个
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("SpringBoot 使用 Swagger2 构建RESTful API")
                //创建人
                .contact(new Contact("Test", "http://www.xuanqi.co/", "631789194@qq.com"))
                //版本号
                .version("1.0")
                //描述
                .description("API帮助文档")
                .build();
    }
}

3、配置Controller

@Slf4j
@RestController
@Api(description = "测试接口")
@RequestMapping("test")
public class TestController extends BaseController {

    @ApiOperation(value = "测试方法",notes = "返回多个测试结果")
    @ApiImplicitParam(name="param",value="测试参数",paramType ="查询",required = true, dataType = "String")
    @GetMapping("constant")
    public String getConstant(String param){
        Map<String,String> map=new HashMap<>();
        map.put("threadName",Thread.currentThread().getName());
        map.put("param",param);

        log.info(JsonUtil.toJson(map));
        return JsonUtil.toJson(map);
    }
}

4、页面效果

http://localhost:9001/web/swagger-ui.html

5、controller测试效果
