The entity class is as follows:

import lombok.Data;
import javax.validation.Valid;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;
import java.util.List;
@Data
public  class OutstoreCodeVO {
    @NotBlank(message = "The outbound order number cannot be empty " )
     private String orderNo;
    
    @Valid
    @NotEmpty(message = "The traceback code array cannot be empty " )
     private List<String> codes;

}

2. Reason analysis: The annotations cannot be recognized due to different versions:

(1), when the version is org.hibernate.validator:hibernate-validator:6.0.13.Final

The imported dependencies are:

import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotEmpty;

(2), when the version is org.hibernate.validator:hibernate-validator:6.2.3.Final

 The imported dependencies must be:

import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.NotEmpty;

3. Solution: Since the version is version 6.2.3, the package introduced by the @NotBlank and @NotEmpty annotations is changed to:

import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.NotEmpty;
