Question

我使用 Elasticsearch 来面对JDBC驱动程序的问题。

我已经下载了必要的文件，它已安装在我的htdocs文件夹中。

这是我安装的路径

e:\xampp\htdocs\search\elasticsearch-1.7.1

我已将JDBC插件安装在同一文件夹中，路径为

e:\xampp\htdocs\search\elasticsearch-1.7.1\plugins\river-jdbc\

以上路径有两个文件

1) elasticsearch-river-jdbc-1.0.0.RC1.2.jar
2) mysql-connector-java-5.1.26-bin.jar

安装完成后，我重新启动了bin文件夹中的elasticsearch.bat。

然后我检查了以下路径中的jdbc

http://localhost:9200/_nodes?settings=true&pretty=true\

我得到了所有细节，这里是插件节点，

"plugins": [

     {
        "name": "river-jdbc",

        "version": "NA",

        "description": "JDBC River",

        "jvm": true,
        "site": false

     }

我希望安装完成。然后我在e:\xampp\htdocs\search\elasticsearch-1.7.1\创建了config.json文件此文件包含以下代码

{
    "type" : "jdbc",
    "jdbc" :{
        "strategy" : "oneshot",
        "driver" : "com.mysql.jdbc.Driver",
        "url" : "jdbc:mysql://localhost:9200/dbname",
        "user" : "root",
        "password" : "",
        "sql" : "select * from tablename",
        "poll" : "1h",
        "scale" : 0,
        "autocommit" : false,
        "fetchsize" : 100,
        "max_rows" : 0,
        "max_retries" : 3,
        "max_retries_wait" : "10s",
        "locale" : "it",
        "digesting" : true,
    },
    "index" : {
        "index" : "jdbc",
        "type" : "jdbc",
        "bulk_size" : 100,
        "max_bulk_requests" : 30,
        "versioning" : false,
        "acknowledge" : false
    }
}

如果我正在运行以下代码

E:\Xampp\htdocs\search\elasticsearch-1.7.1>curl -XPUT "http://127.0.0.1:9200/_river/jdbcriver/_meta" -d @config.json

它显示以下错误，

{"error":"MapperParsingException[failed to parse]; nested: JsonParseException[Un
expected character ('}' (code 125)): was expecting either valid name character (
for unquoted name) or double-quote (for quoted) to start field name\n at [Source
: [B@458c9675; line: 1, column: 495]]; ","status":400}
E:\Xampp\htdocs\search\elasticsearch-1.7.1>

我的遗体有什么遗漏。如何连接表格并获得结果？

Elasticsearch：MapperParsingException [无法解析];嵌套：JsonParseException [未预期的字符（'}'
