今天寫的ES客戶端測試的文件裏一個方法報錯，方法體以下：
java

public IndexResponse createIndex(String indexName, String type,
			String jsonArray) {

		IndexRequestBuilder builder = client.prepareIndex(indexName, type).setSource(jsonArray);
		
		IndexResponse response = builder.execute().actionGet();
		return response;

	}

報錯內容以下：json

在我這裏形成這一異常的緣由是傳遞的參數jsonArray格式不對，我打印了下jsonArray，格式以下：app

[{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}]

這裏正確的格式應該是這樣：

{"name":"hui1","salary":10000.39982635574,"age":8}

即使將原來以 "[" 開關的jsonArray去年「[」,改爲這樣：elasticsearch

{"name":"hui1","salary":10000.39982635574,"age":8},
{"name":"hui2","salary":10000.160206564933,"age":11},
{"name":"hui3","salary":10000.417013742277,"age":28},
{"name":"hui4","salary":10000.26786620842,"age":7}

也同樣會報錯。測試
