一、创建Springboot项目，引入pom依赖

 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.12</version> </dependency> <!-- 只需要引入这一个依赖就行了 --> <dependency> <groupId>org.springdoc</groupId> <artifactId>springdoc-openapi-ui</artifactId> <version>1.5.5</version> </dependency> 

二、配置类请求头携带token

import io.swagger.v3.oas.annotations.ExternalDocumentation; import io.swagger.v3.oas.annotations.OpenAPIDefinition; import io.swagger.v3.oas.annotations.enums.SecuritySchemeIn; import io.swagger.v3.oas.annotations.enums.SecuritySchemeType; import io.swagger.v3.oas.annotations.info.Contact; import io.swagger.v3.oas.annotations.info.Info; import io.swagger.v3.oas.annotations.security.SecurityRequirement; import io.swagger.v3.oas.annotations.security.SecurityScheme; @OpenAPIDefinition( info = @Info( title = "Swagger3", version = "1.0", description = "Swagger3使用演示", contact = @Contact(name = "TOM") ), security = @SecurityRequirement(name = "JWT"), externalDocs = @ExternalDocumentation(description = "参考文档", url = "https://github.com/swagger-api/swagger-core/wiki/Swagger-2.X---Annotations" ) ) @SecurityScheme(type = SecuritySchemeType.HTTP, name = "JWT", scheme = "bearer", in = SecuritySchemeIn.HEADER) public class Swagger3Config { } 

• @OpenAPIDefinition全局只能定义一个，主要配置文档信息和安全配置，这里列举了常用的请求头携带token的安全配置模式
• @OpenAPIDefinition下的info属性配置文档信息
• @OpenAPIDefinition下的security配置认证方式，name属性引入自定义的认证模式
• @SecurityScheme注解就是自定义的认证模式，配置请求头携带token

三、配置文件

server: port: 8080 springdoc: api-docs: #是否开启文档功能 enabled: true #swagger后端请求地址 path: /api-docs swagger-ui: #自定义swagger前端请求路径，输入http：127.0.0.1:8080/test会自动重定向到swagger页面 path: /test #包扫描路径 packages-to-scan: com.hello.controller,com.hello.dto #这里定义了两个分组，可定义多个，也可以不定义 group-configs: #分组名 - group: admin #按路径匹配 pathsToMatch: /admin/ #分组名 - group: user #按包路径匹配 packagesToScan: com.hello.api.user 

四、接口定义

定义两个接口

package com.hello.api.admin; import com.hello.dto.CommonResult; import com.hello.dto.User; import io.swagger.v3.oas.annotations.Operation; import io.swagger.v3.oas.annotations.Parameter; import io.swagger.v3.oas.annotations.media.Content; import io.swagger.v3.oas.annotations.media.Schema; import io.swagger.v3.oas.annotations.responses.ApiResponse; import io.swagger.v3.oas.annotations.tags.Tag; @Tag(name = "AdminControllerApi", description = "管理员相关接口") public interface AdminControllerApi { @Operation(summary = "管理员添加用户", description = "根据姓名添加用户并返回", parameters = { @Parameter(name = "name", description = "姓名") }, responses = { @ApiResponse(description = "返回添加的用户", content = @Content(mediaType = "application/json", schema = @Schema(anyOf = {CommonResult.class, User.class}))), @ApiResponse(responseCode = "400", description = "返回400时候错误的原因") } ) CommonResult<User> addUser(String name); @Operation(summary = "管理员删除用户", description = "根据姓名删除用户") @ApiResponse(description = "返回添加的用户", content = @Content(mediaType = "application/json", schema = @Schema(implementation = User.class))) CommonResult<User> delUser(@Parameter(description = "姓名") String name); @Operation(summary = "管理员更新用户", description = "管理员根据姓名更新用户") @ApiResponse(description = "返回更新的用户", content = @Content(mediaType = "application/json", schema = @Schema(implementation = User.class))) CommonResult<User> updateUser(@Parameter(schema = @Schema(implementation = User.class), required = true, description = "用户类") User user); } 

package com.hello.api.user; import com.hello.dto.User; import io.swagger.v3.oas.annotations.Operation; import io.swagger.v3.oas.annotations.Parameter; import io.swagger.v3.oas.annotations.media.Content; import io.swagger.v3.oas.annotations.media.Schema; import io.swagger.v3.oas.annotations.responses.ApiResponse; import io.swagger.v3.oas.annotations.tags.Tag; @Tag(name = "UserControllerApi", description = "用户的增删改查") public interface UserControllerApi { @Operation(summary = "添加用户", description = "根据姓名添加用户并返回", parameters = { @Parameter(name = "name", description = "姓名") }, responses = { @ApiResponse(description = "返回添加的用户", content = @Content(mediaType = "application/json", schema = @Schema(implementation = User.class))), @ApiResponse(responseCode = "400", description = "返回400时候错误的原因")} ) User addUser(String name); @Operation(summary = "删除用户", description = "根据姓名删除用户", parameters = { @Parameter(name = "name", description = "姓名") }) void delUser(String name); } 

五、实现类

实现刚才的两个接口

package com.hello.controller.admin; import com.hello.api.admin.AdminControllerApi; import com.hello.dto.CommonResult; import com.hello.dto.User; import lombok.extern.slf4j.Slf4j; import org.springframework.web.bind.annotation.*; @RestController @RequestMapping("/admin") @Slf4j public class AdminController implements AdminControllerApi { @PostMapping("/add/{name}") @Override public CommonResult<User> addUser(@PathVariable String name) { return CommonResult.success(new User(name, 18)); } @GetMapping("/del/{name}") @Override public CommonResult<User> delUser(@PathVariable String name) { log.info("管理员删除name={}的用户", name); return CommonResult.success(new User(name, 25)); } @PostMapping("/update") @Override public CommonResult<User> updateUser(@RequestBody User user) { user.setAge(100); log.info("管理员更新{}用户的年龄为{}", user, 100); return CommonResult.success(user); } } 

package com.hello.controller.user; import com.hello.api.user.UserControllerApi; import com.hello.dto.User; import lombok.extern.slf4j.Slf4j; import org.springframework.web.bind.annotation.*; @RestController @RequestMapping("/user") @Slf4j public class UserController implements UserControllerApi { @PostMapping("/add/{name}") @Override public User addUser(@PathVariable String name) { return new User(name, 18); } @GetMapping("/del/{name}") @Override public void delUser(@PathVariable String name) { log.info("删除name={}的用户", name); } } 

六、实体类定义

package com.hello.dto; import io.swagger.v3.oas.annotations.media.Schema; import lombok.AllArgsConstructor; import lombok.Getter; import lombok.Setter; @Getter @Setter @AllArgsConstructor @Schema(name = "CommonResult", description = "通用返回对象") public class CommonResult<T> { @Schema(name = "code", description = "状态码") private long code; @Schema(name = "message", description = "提示信息") private String message; @Schema(name = "data", description = "数据封装") private T data; / * 成功返回结果 * * @param data 获取的数据 */ public static <T> CommonResult<T> success(T data) { return new CommonResult<T>(200, "操作成功", data); } / * 失败返回结果 * * @param message 提示信息 */ public static <T> CommonResult<T> failed(String message) { return new CommonResult<T>(400, message, null); } } 

package com.hello.dto; import io.swagger.v3.oas.annotations.media.Schema; import lombok.AllArgsConstructor; import lombok.Data; @Schema(name="User",description ="用户信息" ) @Data @AllArgsConstructor public class User { @Schema(name = "name",description = "姓名") private String name; @Schema(name = "age",description = "年龄") private int age; } 

七、运行项目查看效果

浏览器输入127.0.0.1:8080/test会重定向到swagger页面

点击右上角的Authorize就会弹出以下界面，输入token，请求接口就会自动携带该token发送请求，这里随便输入一个abc为token，点击Authorize

打开一个接口去测试，查看效果，发现请求已经自动携带了token
