示例

@ApiModel("SysUser实体类")
@Data
public class SysUser {

    @ApiModelProperty(value = "id", required = true)
    private Integer id;

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

    @ApiModelProperty(value = "birth", required = true)
    private Date birth;

}

@Api(tags = "sysUser管理")
@RestController
@RequestMapping(value = "sysUser", produces = "application/json; charset=utf-8")
public class SysUserController {

    @ApiOperation("参数校验测试")
    @ApiImplicitParam(name = "sysUser", required = true)
    @PostMapping("test")
    public Result<SysUser> test(@RequestBody SysUser sysUser) {
        return AjaxResult.success(sysUser);
    }

    @ApiOperation("接口测试")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "name", required = true)
    })
    @GetMapping("test2")
    public Result<String> test2(@RequestParam("name") String name) {
        return AjaxResult.success("OK: " + name);
    }

常用注解

@Api(tags = "sysUser管理")
// 放在controller类上，描述当前controller

@ApiOperation("接口测试")
// 放在接口上，描述当前接口

@ApiImplicitParam(name = "sysUser", required = true)
// 放在接口上，描述当前接口参数--->单个参数时

@ApiImplicitParams({
	@ApiImplicitParam(name = "name", required = true),
	@ApiImplicitParam(name = "age", required = true)
})
// 放在接口上，描述当前接口参数--->多个参数时

@ApiModel("SysUser实体类")
// 放在实体类上，描述当前实体类

@ApiModelProperty(value = "id", required = true)
// 放在实体类的属性上，描述当前属性
