StartWithValidator.class

public class StartWithValidator implements ConstraintValidator {  private String start;  @Override  public void initialize(StartWithValidation constraintAnnotation) {    start = constraintAnnotation.start();  }  @Override  public boolean isValid(String value, ConstraintValidatorContext context) {    if (!StringUtils.isEmpty(value)) {      return value.startsWith(start);    }    return true;  }}

运用

@StartWithValidation(message = "Param 'address' must be start with 'Beijing'.", start = "Beijing")public String address;

解释：

地址必须以Beijing开头，否则校验失败
