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");
