实现

多个数据同步job就新建多个json文件,每个json文件中执行一次的job

比如第一个同步的json文件内容:

{
    "job": {
        "content": [
            {
                "reader": {
                    "name": "mysqlreader",
                    "parameter": {
                        "column": [
						"station_id",
						"station_number",
						"group_id",
						"mine_id",
						],
                        "connection": [
                            {
                                "jdbcUrl": [
								"jdbc:mysql://127.0.0.1:3306/数据库名?useUnicode=true&characterEncoding=gbk"
								],
                                "table": [
								"表名"
								]
                            }
                        ],
                        "password": "密码",
                        "username": "用户名",
                        "where": ""
                    }
                },
                "writer": {
                    "name": "mysqlwriter",
                    "parameter": {
                        "column": [
						"station_id",
						"station_number",
						"group_id",
						"mine_id",
						],
                        "connection": [
                            {
                                "jdbcUrl": "jdbc:mysql://127.0.0.1:3306/数据库名?useUnicode=true&characterEncoding=gbk",
                                "table": [
								"表名"
								]
                            }
                        ],
                        "password": "密码",
                        "preSql": [
						"delete from 表名"
						],
                        "session": [],
                        "username": "root",
                        "writeMode": "insert"
                    }
                }
            }
        ],
        "setting": {
            "speed": {
                "channel": "5"
            }
        }
    }
}

注意将数据库地址、名称、表名、列名、用户名、密码等改成自己对应。

然后再新建第二个数据同步的json文件

{
    "job": {
        "content": [
            {
                "reader": {
                    "name": "mysqlreader",
                    "parameter": {
                        "column": [
						"id",
						"location_number",
						"car_num",
						],
                        "connection": [
                            {
                                "jdbcUrl": [
								"jdbc:mysql://127.0.0.1:3306/数据库名?useUnicode=true&characterEncoding=gbk"
								],
                                "table": [
								"表名"
								]
                            }
                        ],
                        "password": "密码",
                        "username": "用户名",
                        "where": ""
                    }
                },
                "writer": {
                    "name": "mysqlwriter",
                    "parameter": {
                        "column": [
						"id",
						"location_number",
						"car_num",
						],
                        "connection": [
                            {
                                "jdbcUrl": "jdbc:mysql://127.0.0.1:3306/数据库名?useUnicode=true&characterEncoding=gbk",
                                "table": [
								"表名"
								]
                            }
                        ],
                        "password": "密码",
                        "preSql": [
						"delete from 表名"
						],
                        "session": [],
                        "username": "用户名",
                        "writeMode": "insert"
                    }
                }
            }
        ],
        "setting": {
            "speed": {
                "channel": "5"
            }
        }
    }
}

将此两个json文件放在datax的bin目录下

并在此目录下新建bat文件

#设置编码
chcp 65001
@echo off
title "自定义标题"
set INTERVAL=3600
timeout %INTERVAL%
 
:Again

python datax.py  ./busCarInfoViewMysql2Mysql.json

ping 127.0.0.1 -n 5

python datax.py  ./tBaseStationMysql2Mysql.json

echo %date% %time:~0,8%
 
timeout %INTERVAL%
 
goto Again

这里的3600就代表每3600秒执行一次。

ping 127.0.0.1 -n 5 目的是为了中间停顿5秒。
