注解：Springfox改用Springdoc后，注解改变：
@Api → @Tag@ApiIgnore → @Parameter(hidden = true) or @Operation(hidden = true) or @Hidden@ApiImplicitParam → @Parameter@ApiImplicitParams → @Parameters@ApiModel → @Schema@ApiModelProperty(hidden = true) → @Schema(accessMode = READ_ONLY)@ApiModelProperty → @Schema@ApiOperation(value = "foo", notes = "bar") → @Operation(summary = "foo", description = "bar")@ApiParam → @Parameter@ApiResponse(code = 404, message = "foo") → @ApiResponse(responseCode = "404", description = "foo")实用新增注解：
@ParameterObject 案例
@Tag(name = "用户接口")
@RestController
@RequestMapping("sys/user")
public class SysUserController {@Resourceprivate ISysUserService sysUserService;@Operation(summary = "分页查询")@GetMapping("page")public AjaxResult queryPage(@ParameterObject SysUserPageDTO dto) {PageInfo page = sysUserService.queryPage(dto);return AjaxResult.success(page);}@Operation(summary = "详情")@GetMapping("{id}")public AjaxResult queryInfo(@PathVariable Long id) {SysUserDTO dto = sysUserService.queryById(id);return AjaxResult.success(dto);}@Operation(summary = "新增")@PostMappingpublic AjaxResult save(@RequestBody SysUserDTO dto) {Long id = sysUserService.saveInfo(dto);return AjaxResult.success(id);}
}@Getter
@Setter
@TableName("user")
@Schema(name = "User", description = "$!{table.comment}")
public class User implements Serializable {private static final long serialVersionUID = 1L;@Schema(description = "主键")@TableId("id")private Long id;@Schema(description = "用户名")@TableField("name")private String name;@Schema(description = "手机号")@TableField("phone")private String phone;@Schema(description = "性别")@TableField("sex")private String sex;@Schema(description = "状态 0:禁用，1:正常")@TableField("status")private Integer status;
