爲JDBC彈性搜索河設置映射

我將ES 0.20.6與elasticsearch-river-jdbc plugin一起使用。我創建了一個工程，並使用一條河：爲JDBC彈性搜索河設置映射

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 
    } 
}'

現在我想的是添加類型映射爲the option is defined in the plugin documentation。但我真的cant't找出語法和始終得到以下錯誤（與"Source: "部分的變化取決於我嘗試）

我想您所提交的東西，甚至不是一個正確的JSON對象。我可以想象，type_mapping對象必須包含映射，幾乎與使用put mapping api或creating索引所提交的映射幾乎相同。

哇，謝謝。我甚至都沒有想過。我使用繼續的json符號來設置映射，但是我需要在我的json對象中有一個json字符串...工作方式：''type_mapping「：」{\「mytype \」：{\「properties \」：{\ 「活性\」：{\ 「類型\」：\ 「布爾\」，\ 「存儲\」：\ 「是\」}}}}「'。非常感謝！ – Crystark

我必須補充一點，我使用的是Chrome Sense，並且甚至在json對象內的回車符也非常特殊。 – dickyj

在ElasticSearch 1.0.0中，你應該這樣做：http://ondrej-kvasnovsky.blogspot.com/2013/10/how-to-configure-jdbc-river-for.html –
