json - 将 json 附加到 groovy 中的 json

Question

我是 groovy 的新手。我的要求是我必须将一个 json 附加到一个 json 中。我的代码如下:

我构造的JSON:

def builder = new groovy.json.JsonBuilder()
   def root=builder.event{                
            type  "model_output_load_init"
            time new Timestamp(date.getTime())
            status "success"                        
        }

来自数据库的 JSON:

def json = rs.getString("status");

现在我必须将构造附加到来自数据库的 JSON 中。请帮我解决这个问题。提前致谢。

编辑:

我构造的 JSON:

{
    "event": {
        "type": "model_output_load_init",
        "time": "2015-10-01T14:08:17+0000",
        "status": "success"
    }
}

来自数据库的 JSON:

{
    "model_build": {
        "Initialized": {
            "Timestamp": ""
        }
    },
    "modelExec": {
        "Initialized": {
            "Timestamp": ""
        }
    }
}

需要的输出:

{
    "model_build": {
        "Initialized": {
            "Timestamp": ""
        }
    },
    "modelExec": {
        "Initialized": {
            "Timestamp": ""
        }
    },
    "event": {
        "type": "model_output_load_init",
        "time": "2015-10-01T14:08:17+0000",
        "status": "success"
    }

}

您可以附加到 JsonSlurper 生成的 map 。

import groovy.json.JsonBuilder
import groovy.json.JsonSlurper

def builder = new JsonBuilder()
def root = builder.event{                
    type  "model_output_load_init"
    time new Timestamp(date.getTime())
    status "success"                        
}

// Simulates the JSON from DB
def json = new JsonSlurper().parseText('''
{
    "model_build": {
        "Initialized": {
            "Timestamp": ""
        }
    },
    "modelExec": {
        "Initialized": {
            "Timestamp": ""
        }
    }
}''')

// Append the built JSON to the "slurped" JSON
json.event = root.event

// Re-build the JSON so it can saved as a String
new JsonBuilder(json).toPrettyString()

输出看起来像这样:

{
    "event": {
        "type": "model_output_load_init",
        "time": "2015-10-01T14:39:11+0000",
        "status": "success"
    },
    "modelExec": {
        "Initialized": {
            "Timestamp": ""
        }
    },
    "model_build": {
        "Initialized": {
            "Timestamp": ""
        }
    }
}
