Springboot整合Swagger3全注解配置(springdoc-openapi-ui)

时间：2023-03-16 11:37:43|栏目：JAVA代码|点击：次

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;
}
