Question

我有两个带有构造函数的不同类，但具有相似的pojo，并且我想实现Java继承，因为在运行声纳代码分析时会给我代码重复

我创建了DaoException和ServiceException类，它们具有相同的pojo，并且希望使用公共pojo以避免代码重复

public class DaoException extends Exception {

  private static final long serialVersionUID = 1L;

  private final int code;
  private String message;


  public DaoException(int code, String message) {

      this.code = code;
      this.message = message;
  }

  public DaoException(int code, Throwable throwable) {

      this.code = code;
      this.message = throwable.getMessage();
  }

  public int getCode() {

      return code;
  }

  public void setCode(int code) {

      this.code = code;
  }

  public String getMessage() {

      return message;
  }

  public void setMessage(String message) {

      this.message = message;
  }
}

public class ServiceException extends Exception {

private static final long serialVersionUID = 1L;

private final int code;
private String message;

public ServiceException(int code, String message) {

    this.code = code;
    this.message = message;
}

public ServiceException(int code, Throwable throwable) {

    this.code = code;
    this.message = throwable.getMessage();
}

public int getCode() {

    return code;
}

public void setCode(int code) {

    this.code = code;
}

public String getMessage() {

    return message;
}

public void setMessage(String message) {

    this.message = message;
}

}

请告知。

您可以为ServiceException和DAOExecption创建一个公共父类。您可以创建带有所有详细信息的类GenericException。然后使ServiceException和DAOExecption扩展此GenericException。从孩子那里调用适当的父类的构造函数
