elasticsearch配置mapping时，对所有的type有效

在elasticsearch中一个index下面会有很多的type，在一个项目中type的数量未知，所以在建立template的时候需要mapping不指定type（对所有的type有效）
因此需要用到_default_字段：

PUT /my_index{
"mappings": {
    "_default_": {
            "properties": {
                "field1": {
                    "type": "string",
                    "index": "analyzed"
                }
             }
     }
}

在项目中需要用到的配置帖出来，大家参考：

{
    "template":"projectlog*",
    "settings":{
         "number_of_shards" : 5
    },
    "mappings": {

            "_default_": {
                "_source" : { "enabled" : true },
                "properties": {
                    "additionInfo": {
                        "type": "string",
                        "index": "not_analyzed" },
                    "devEnv": {
                        "type": "string",

                    "eventId": {
                        "type": "string",

                    "eventName": {
                        "type": "string",
                        "index": "not_analyzed" },

                        "index": "not_analyzed" },
                    "ip": {
                        "type": "string",

                    "ruleId": {
                        "type": "string",

                }
            }
