Controller接参代码

@PostMapping("/add")
	@ApiOperation(value = "添加活动信息")
	public Result<ActivityVo> activityAdd(@RequestBody @Valid ActivityDTO activityDTO) throws UnsupportedEncodingException {
		return activityService.activityAdd(activityDTO);
	}

接参实体类

package com.qingke.studytour.manager.entity.dto;

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

import javax.validation.constraints.NotBlank;
import java.math.BigDecimal;
import java.util.Date;

@NotBlank注解源码

可以看到该注解支持校验类型CharSequence类型的实体对象

The annotated element must not be {@code null} and must contain at least one

• non-whitespace character. Accepts {@code CharSequence}.
