es java api 设置index mapping 报错 mapping source must be pairs of fieldnames and properties definition.

java.lang.IllegalArgumentException: mapping source must be pairs of fieldnames and properties definition.

从es官网找到的

request.mapping("_doc",
        "{\n" +
        "  \"_doc\": {\n" +
        "    \"properties\": {\n" +
        "      \"message\": {\n" +
        "        \"type\": \"text\"\n" +
        "      }\n" +
        "    }\n" +
        "  }\n" +
        "}",
        XContentType.JSON);不生效并报错查看源码，发现mapping的第二个参数，要求必须为 %2==0，改为

request.mapping("_doc", "datetime", "type=date");多个参数

request.mapping("_doc", "datetime", "type=date", "string", "type=text");
