为JDBC弹性搜索河设置映射

我将ES 0.20.6与elasticsearch-river-jdbc plugin一起使用。我创建了一个工程，并使用一条河：为JDBC弹性搜索河设置映射

SQL="SELECT ..." 
curl -XPUT 'localhost:9200/_river/myindex_river/_meta' -d '{ 
    "type" : "jdbc", 
    "jdbc" : { 
     "driver" : "org.postgresql.Driver", 
     "url" : "jdbc:postgresql://localhost:5432/mydb_db", 
     "user" : "myuser", 
     "password" : "mypassword", 
     "sql" : "'"$SQL"'" 
    }, 
    "index" : { 
     "index" : "myindex", 
     "type" : "mytype", 
     "type_mapping" : null 
    } 
}'

现在我想的是添加类型映射为the option is defined in the plugin documentation。但我真的cant't找出语法和始终得到以下错误（与"Source: "部分的变化取决于我尝试）

我想您所提交的东西，甚至不是一个正确的JSON对象。我可以想象，type_mapping对象必须包含映射，几乎与使用put mapping api或creating索引所提交的映射几乎相同。

哇，谢谢。我甚至都没有想过。我使用继续的json符号来设置映射，但是我需要在我的json对象中有一个json字符串...工作方式：''type_mapping“：”{\“mytype \”：{\“properties \”：{\ “活性\”：{\ “类型\”：\ “布尔\”，\ “存储\”：\ “是\”}}}}“'。非常感谢！ – Crystark

我必须补充一点，我使用的是Chrome Sense，并且甚至在json对象内的回车符也非常特殊。 – dickyj

在ElasticSearch 1.0.0中，你应该这样做：http://ondrej-kvasnovsky.blogspot.com/2013/10/how-to-configure-jdbc-river-for.html –
