一：引入依赖包
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-validation -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>二：在注解里标记清楚规则
@Data
public class Test01VO {
@NotNull(message = "ID不能为空")
private Integer id;
@Min(0)
@Max(5)
private Integer score;
private String content;
}三：在Controller里使用@Validated注解
@PostMapping("/test01")
public String test(@Validated @RequestBody Test01VO test01vo) {
System.out.print("test>>>>>>>>>"+test01vo.getId());
return "success";
}四：调用接口验证是否生效
参数：
{
"id": "",
"score": 5
}返回参数异常：
{
"code": 410,
"msg": "ID不能为空; ",
"data": null,
"traceId": null
}参数：
{
"id": "1",
"score": "10"
}返回参数异常：
{
"code": 410,
"msg": "must be less than or equal to 5; ",
"data": null,
"traceId": null
}参数：
{
"id": "1",
"score": 5
}返回值：
success
以上就是使用注解@Validated效验VO参数是否合规的详细内容，更多关于@Validated效验VO参数的资料请关注编程网其它相关文章！
