例如在同一个包下定义如下的enum

    1. syntax = "proto3";
    2. package proto;
    3. enum SpiderStatus {
    4.     IDEAL = 0; //开始
    5.     RUNNING = 1; //执行中
    6.     END = 2; //结束
    7.     START = 3; //空闲中
    8.     Waiting = 4; //队列等待中
    9.     Error = 5; //发生错误
    10.     UNKNOW = -1;
    11.     Connect = 60; //客户端链接
    12.     Disconnect = 61; //客户端断开链接
    13. }
    14. enum ContentStatus {
    15.     UNUSED = 0;
    16.     DISABLE = 1;
    17.     RELEASE = 2;
    18.     UNKNOW=-1;
    19. }
    20. #这里UNKNOW出现了两次会报错，为了避免这种情况一般实用前缀避免,他这样做的原因是兼容才c++的语法
    21. enum SpiderStatus {
    22.     SpiderStatus_IDEAL = 0; //开始
    23.     SpiderStatus_RUNNING = 1; //执行中
    24.     SpiderStatus_END = 2; //结束
    25.     SpiderStatus_START = 3; //空闲中
    26.     SpiderStatus_Waiting = 4; //队列等待中
    27.     SpiderStatus_Error = 5; //发生错误
    28.     SpiderStatus_UNKNOW = -1;
    29.     SpiderStatus_Connect = 60; //客户端链接
    30.     SpiderStatus_Disconnect = 61; //客户端断开链接
    31. }
    32. enum ContentStatus {
    33.     ContentStatus_UNUSED = 0;
    34.     ContentStatus_DISABLE = 1;
    35.     ContentStatus_RELEASE = 2;
    36.     ContentStatus_UNKNOW=-1;
    37. }
