Java 如何优雅的抛出业务异常

 public interface IErrorCode {
   public String value();
 }

import java.util.EnumMap;

import com.test.IErrorCode;

public enum MyBusinessErrorCode implements IErrorCode {

  /**
   * 角色不存在或已被删除
   */
  ERR_MODEL_001,
  /**
   * 角色编码已存在
   */
  ERR_MODEL_002;

  private static EnumMap<MyBusinessErrorCode, String> errorCodeMap = new EnumMap<MyBusinessErrorCode, String>(
      MyBusinessErrorCode.class);

  static {
    errorCodeMap.put(ERR_MODEL_001, "角色不存在！");
    errorCodeMap.put(ERR_MODEL_002, "角色编码已存在！");
  }

  public String value() {
    return errorCodeMap.get(this);
  }
}

public class ExceptionUtil {

  /**
   * 获取业务异常类
   */
  public static BusinessException CreateBusinessException(
      IErrorCode code) {
    return new BusinessException(code);
  }

  /**
   * 获取带数据格式化的业务异常类
   *
   * @param code
   */
  public static BusinessException CreateFormatedBusinessException(BusinessErrorCode code, Object ... object){
    String str = code.value();
    str = String.format(str, object);
    return new BusinessException(code.name(), str, "");
  }

}

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    Date date;
    try {
      // 申请时间
      date = sdf.parse(form.getApplyDateView());
    } catch (ParseException e) {
      throw ExceptionUtil.CreateBusinessException(MyBusinessErrorCode.ERR_RBM_005);
    }
