使用注解@Validated效验VO参数是否合规

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
