Springboot2.x整合Swagger3.x

作者:互联网

1、SpringBoot添加pom文件依赖

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.11</version>
        <relativePath/>
    </parent>

    <properties>
        <java.version>11</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--swagger3依赖-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-boot-starter</artifactId>
            <version>3.0.0</version>
        </dependency>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.16</version>
            <scope>provided</scope>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

 

2、配置文件增加配置

server:
  port: 8082

spring:
  application:
    name: swagger-server

swagger:
  enable: true
  application-name: ${spring.application.name}
  application-version: 1.0
  application-description: 电商平台管理后端接口文档

 

3、创建配置类

import io.swagger.annotations.ApiOperation;
import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.ApiKey;
import springfox.documentation.service.Contact;
import springfox.documentation.service.SecurityScheme;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

import java.util.ArrayList;
import java.util.List;

@Component
@EnableOpenApi
@ConfigurationProperties("swagger")
@Data
public class SwaggerConfiguration {
    /**
     * 是否开启swagger,生产环境一般关闭,所以这里定义一个变量
     */
    private Boolean enable;

    /**
     * 项目应用名
     */
    private String applicationName;

    /**
     * 项目版本信息
     */
    private String applicationVersion;

    /**
     * 项目描述信息
     */
    private String applicationDescription;

    @Bean
    public Docket docket() {
        return new Docket(DocumentationType.OAS_30)
                .pathMapping("/")
                // 定义是否开启swagger,false为关闭,可以通过变量控制,线上关闭
                .enable(enable)
                //配置api文档元信息
                .apiInfo(apiInfo())
                // 选择哪些接口作为swagger的doc发布
                .select()
                //apis() 控制哪些接口暴露给swagger,
                // RequestHandlerSelectors.any() 所有都暴露
                // RequestHandlerSelectors.basePackage("net.xdclass.*")  指定包位置
                // withMethodAnnotation(ApiOperation.class)标记有这个注解 ApiOperation
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any()).build()
                // 如何保护我们的Api,有三种验证(ApiKey, BasicAuth, OAuth)
                .securitySchemes(security())
                // 接口文档的基本信息
                .apiInfo(apiInfo());
    }


    /**
     * 接口文档详细信息
     *
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title(applicationName)
                .description(applicationDescription)
                .contact(new Contact("联系标题", "https://www.baidu.com", "510716143@qq.com"))
                .version(applicationVersion)
                .build();
    }

    private List<SecurityScheme> security() {
        ArrayList<SecurityScheme> apiKeys = new ArrayList<>();
        apiKeys.add(new ApiKey("accessToken", "accessToken", "accessToken"));
        return apiKeys;
    }


}

4、创建controller类

import com.example.model.User;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import io.swagger.v3.oas.annotations.responses.ApiResponse;
import io.swagger.v3.oas.annotations.responses.ApiResponses;
import org.springframework.web.bind.annotation.*;

import java.util.ArrayList;
import java.util.List;

@Api(tags = "测试接口")
@RestController
@RequestMapping("demo")
public class DemoController {

    @ApiOperation("查询集合数据")
    @ApiImplicitParams(value = {
            @ApiImplicitParam(name = "id",value = "查询id"),
            @ApiImplicitParam(name = "name",value = "查询名称",required = true)
    })
    @ApiResponses({
            @ApiResponse(responseCode = "200", description ="OK"),
            @ApiResponse(responseCode = "204", description ="No results returned")
    })
    @PostMapping("list1")
    public List<String> list1(Integer id,String name){
        List<String> list = new ArrayList<>();
        list.add("张三");
        list.add("李四");
        return list;
    }

    @ApiOperation("测试删除")
    @ApiImplicitParam(name = "id", value = "删除ID", example = "100", required = true)
    @PostMapping(value = "/delete/{id}")
    public Integer delete(@PathVariable("id") Long id){
        System.out.println("删除成功:"+id);
        return 200;
    }

    @ApiOperation("保持对象")
    @PostMapping("save")
    public Object save(@RequestBody User user){
        User user1 = new User();
        user1.setId(user.getId());
        user1.setName(user.getName());
        return user1;
    }

}

 

5、访问 http://localhost:8082/swagger-ui/index.html

 

6、常用注解,官网

@Api()用于类;
表示标识这个类是swagger的资源


@ApiOperation()用于方法;
表示一个http请求的操作


@ApiParam()用于方法,参数,字段说明;
表示对参数的添加元数据(说明或是否必填等)


@ApiModel()用于类
表示对类进行说明,用于参数用实体类接收


@ApiModelProperty()用于方法,字段
表示对model属性的说明或者数据操作更改


@ApiIgnore()用于类,方法,方法参数
表示这个方法或者类被忽略


@ApiImplicitParam() 用于方法
表示单独的请求参数


@ApiImplicitParams() 用于方法,包含多个 @ApiImplicitParam

具体使用举例说明:


@Api()
用于类;表示标识这个类是swagger的资源
tags–表示说明
value–也是说明,可以使用tags替代
