spring 注解@Validated验证大于或小于浮点数使用方法
引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
在需要添加注解的dto类中添加@DecimalMax或@DecimalMin注解
import java.io.Serializable;
import java.math.BigInteger;
import lombok.Data;
import javax.validation.constraints.*;
@Data
public class RedEnvelopDto implements Serializable {
private static final long serialVersionUID = 1L;
@NotNull(message = "不能为空")
@DecimalMin(value = "0.01",message = "红包金额必须大于或等于0.01")
@DecimalMax(value = "10000" ,message = "红包金额必须小于或等于10000")
private String totalMoney;
@NotNull(message = "不能为空")
private BigInteger sendId;
}
- 关于 Flowchart流程图 语法，参考 [这儿][4].
在controller层方法参数中添加@Validated注解
@PostMapping(value = "/api/setred")
public Result<Object> setRed(@Validated @RequestBody RedEnvelopDto redEnvelopDto) {
return null;
}
