我正在使用Hibernate Script Assert进行条件验证： 如果commRolesId包含4并且gnrlTransportersId数组列表为空，我想显示错误消息。
@ScriptAssert(lang="javascript",script="this.commRolesId.indexOf(4) >= 0 && _this.gnrlTransportersId.length == 0",message="{notBlank.message}")
public class CommUserDto {
@Size(min = 1,message = "{notBlank.message}")
private List<Long> commRolesId = new ArrayList<>();
private List<Long> gnrlTransportersId = new ArrayList<>();
}
但是，即使commRolesId数组不包含4，它也会抛出该消息。
请帮助。谢谢。
编辑：
import java.util.ArrayList;
import java.util.List;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.ScriptAssert;
@ScriptAssert(
lang = "javascript",script = "!(_this.commRolesId.contains(4) && _this.gnrlTransportersId.isEmpty())",message = "errorMessage")
public class CommUserDto {
@Size(min = 1,message = "should not be empty")
private List<Long> commRolesId = new ArrayList<>();
private List<Long> gnrlTransportersId = new ArrayList<>();
public List<Long> getCommRolesId() {
return commRolesId;
}
public void setCommRolesId(List<Long> commRolesId) {
this.commRolesId = commRolesId;
}
public List<Long> getGnrlTransportersId() {
return gnrlTransportersId;
}
public void setGnrlTransportersId(List<Long> gnrlTransportersId) {
this.gnrlTransportersId = gnrlTransportersId;
}
}
测试：
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
public class Test {
public static void main(String[] args) {
CommUserDto dto = new CommUserDto();
List<Long> commRolesId = new ArrayList<>();
commRolesId.add(1L);
List<Long> gnrlTransportersId = new ArrayList<>();
dto.setGnrlTransportersId(gnrlTransportersId);
dto.setCommRolesId(commRolesId);
Validator validator = Validation.buildDefaultValidatorFactory().getValidator();
Set<ConstraintViolation<CommUserDto>> constraintViolations = validator.validate(dto);
System.out.println(constraintViolations.size());
System.out.println(constraintViolations);
}
}
