Swagger是一款好用的Java接口文档工具，引入Maven坐标之后就可以在项目启动之后，通过访问相应的地址可以看到生成好的接口文档。

• 官网：https://swagger.io/
• 官方接口文档：http://docs.swagger.io/swagger-core/apidocs/index.html
• Github：https://github.com/swagger-api

一、页面效果1

**访问地址：**http://localhost:8081/swagger-ui.html

依赖方式1：
（只支持效果1的展示形式）

<!-- swagger -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>${swagger.version}</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>1.18.18</version>
</dependency>

二、页面效果2

**访问地址：**http://localhost:8081/doc.html

依赖方式2：
（支持效果1 和 效果2 的展示形式）

<!-- swagger -->
<dependency>
    <groupId>com.open.capacity</groupId>
    <artifactId>swagger-spring-boot-starter</artifactId>
    <version>2.0.1</version>
</dependency>

三、Swagger配置类

import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
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;

import java.util.HashSet;
import java.util.Set;

/**
 * <p> @Title SwaggerConfig
 * <p> @Description Swagger 配置类
 *
 * @author ACGkaka
 * @date 2021/4/23 15:40
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket buildDocket() {

        /// accessToken 请求头要求
//        ParameterBuilder ticketPar = new ParameterBuilder();
//        List<Parameter> parameters = new ArrayList<>();
//        ticketPar.name("accessToken").description("accessToken")
//                .modelRef(new ModelRef("string")).parameterType("header")
//                .required(false).build();
//        parameters.add(ticketPar.build());

        Set<String> consumes = new HashSet<>();
        consumes.add("multipart/form-data");
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
//                .apis(RequestHandlerSelectors.any())
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build()
//                .globalOperationParameters(parameters)
                .consumes(consumes);
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Demo System")
                .description("Demo System API")
                .version("V1.0")
                .build();
    }
}

四、接口注解形式

import com.demo.swagger.query.DemoQueryParam;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

/**
 * <p> @Title DemoController
 * <p> @Description Controller 接口
 *
 * @author ACGkaka
 * @date 2021/4/24 23:35
 */
@Api(tags = "接口类")
@RestController
@RequestMapping("/demo")
public class DemoController {

    @ApiOperation("get接口")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id", value = "主键", dataType = "String", paramType = "json", required = true)
    })
    @GetMapping("/get")
    public String get(String id) {
        return id;
    }

    @ApiOperation("post接口")
    @PostMapping("/post")
    public DemoQueryParam post(@RequestBody DemoQueryParam param) {
        return param;
    }
}

五、POST 请求体注解

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

/**
 * <p> @Title DemoQueryParam
 * <p> @Description Demo 请求体
 *
 * @author ACGkaka
 * @date 2021/4/24 23:41
 */
@Data
@ApiModel(description = "请求入参")
public class DemoQueryParam {

    /**
     * 主键
     */
    @ApiModelProperty(value = "主键", required = true)
    private String id;

    /**
     * 姓名
     */
    @ApiModelProperty(value = "姓名", required = true)
    private String name;

    /**
     * 年龄
     */
    @ApiModelProperty("年龄")
    private Integer age;
}
