log4z

new golang package log config for zap

底层根据zap的log库，超高性能

可以轻松根据配置文件初始哈logger，并且可以快速生成不同的logger，每个logger里面有不同的level定义配置

最后提供了默认console的logger配置，这样在写testcase的时候不用担心logger没有初始化的问题

var LoggerCommon *zap.Logger
var LoggerWechat *zap.Logger

func ExampleInit() {        
    configPath := "./conf/log4z.xml"
    loggerMap := log4z.InitLogger(configPath)
    LoggerCommon = getLoggerOrConsole(loggerMap, "Common")
    LoggerWechat = getLoggerOrConsole(loggerMap, "Wechat")

    fmt.Println("LoggerCommon", LoggerCommon)
    fmt.Println("LoggerWechat", LoggerWechat)
}

func getLoggerOrConsole(dict map[string]*zap.Logger, key string) *zap.Logger {
    logger, ok := dict[key]
    if ok {
        fmt.Printf("info: get logger %s success\r\n", key)
    } else {
        fmt.Printf("warnning: log4z get logger (%s) failed\r\n", key)
        fmt.Printf("warnning: now set logger %s to default console logger\r\n", key)
        logger = log4z.GetConsoleLogger()
    }
    return logger
}

根据这样的写法，兼顾了生产代码和测试用例的需求
