原因:

下面jdbcUrl只能指定一个路径,将列表转为字符串即可
"jdbcUrl":["jdbc:mysql://localhost:3306/temp?characterEncoding=utf8"]改为
"jdbcUrl":"jdbc:mysql://localhost:3306/temp?characterEncoding=utf8"

"writer": {
               "name": "mysqlwriter",
               "parameter": { 
                   "username":"root",
                   "password":"xxx",
                   "column" : [ "id",  "name" ],
				"connection": [
				{
					"table": ["table2"],
					"jdbcUrl":["jdbc:mysql://localhost:3306/temp?characterEncoding=utf8"]
				}]
               }
           }
