JSR303数据校验

1.导入依赖

<dependency>
            <groupId>jakarta.validation</groupId>
            <artifactId>jakarta.validation-api</artifactId>
            <version>2.0.2</version>
        </dependency>

 

2.给要校验的javaBean上标注校验注解

@Validated
public class Dog

给对象属性添加校验注解

@Email(message = "邮箱格式错误")
private String name;
