先上代碼看一下

import com.hisense.common.utils.ResultVOUtil;
import com.hisense.common.vo.ResultVO;
import com.hisense.home.model.SysLoginModel;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

import org.springframework.web.bind.annotation.RequestMapping;

@RestController
@RequestMapping("/sys")
@Api(tags="用戶登錄")

public class LoginController {

    @ApiOperation("登錄接口")
    @PostMapping("/login")
    public ResultVO login(@Valid @RequestBody SysLoginModel sysLoginModel, BindingResult bindingResult){

        if (bindingResult.hasErrors()){
            return ResultVOUtil.error(1000,bindingResult.getAllErrors().get(0).getDefaultMessage());
        }


        return ResultVOUtil.success();
    }
}

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

import javax.validation.constraints.NotEmpty;

/**

@Data
@ApiModel(value="登錄對象", description="登錄對象")
public class SysLoginModel {
    @NotEmpty(message = "手機號不能為空")
    @ApiModelProperty(value = "賬號")
    private String userName;
    @NotEmpty(message = "密碼不能為空")
    @ApiModelProperty(value = "密碼")
    private String password;
    @NotEmpty(message = "驗證碼不能為空")

    private String captcha;
}

@Valid 如果爆紅，請檢查一下springboot版本是否大于 2.3.0

解決辦法有兩種。第一種是降低springboot版本小于2.3.0 第二種辦法是比較推薦的，就是pom新增如下：

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-validation</artifactId>
        </dependency>
