    datax下载地址:http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz

    步骤:

    1,环境准备:

      JDK1.8

         Python2.7

           DataX

    2,测试安装是否成功,打开命令界面

      ①cd (你的datax安装目录)in

      ②py -2 {YOUR_DATAX_HOME}/bin/datax.py {YOUR_DATAX_HOME}/job/job.json  如:py -2 E:MySoftWaredataxdataxindatax.py E:MySoftWaredataxdataxjobjob.json

      如果成功:

      则出现以下界面则成功,若出现乱码,输入CHCP 65001,即可解决

     3,创建mysql数据表和csv文件,测试csv导入mysql表

    mysql表:

    CREATE TABLE `demo` (
      `id` varchar(11) NOT NULL,
      `name` varchar(255) DEFAULT NULL,
      `age` varchar(255) DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    View Code

    csv样式:

    demo.json:

    {
        "job": {
            "content": [
                {
                    "reader": {
                        "name": "txtfilereader", 
                        "parameter": {
                        "path": ["E:/example/demo.csv"], 
                        "encoding":"GBK",
                            "column": [
                                {
                                    "index": 0,
                                    "type": "string"
                                },
                                {
                                    "index": 1,
                                    "type": "string"
                                },
                                {
                                    "index": 2,
                                    "type": "string"
                                },
                            ],
                        "skipHeader": "true"
                        }
                    }, 
                    "writer": {
                        "name": "mysqlwriter", 
                        "parameter": {
                            "column": [
                            "id",
                            "name",
                            "age",
                            ], 
                            "connection": [
                                {
                                    "jdbcUrl": "jdbc:mysql://localhost:3306/data?useUnicode=true&characterEncoding=utf8", 
                                    "table": ["demo"]
                                }
                            ], 
                            "password": "123456", 
                            "username": "root",
                            "preSql":[""],
                            "session":["set session sql_mode='ANSI'"],
                            "writeMode":"insert"
                        }
                    }
                }
            ], 
            "setting": {
                "speed": {
                    "channel": "1"
                }
            }
        }
    }
    View Code

    使用命令:py -2 E:MySoftWaredataxdataxindatax.py E:exampledemo.json

    运行结果如下:

      成功将数据导入mysql中。

    3,遇到的错误。

    我遇到的错误有 您提供的配置信息不是合法的JSON格式: syntax error, position at 795, name fieldDelimiter 

    因为我json文件中加上了"fieldDelimiter":"," 这种写法不对,删除即可。
