JsonBuilder将对象动态转为json

 

代码如下：

 

import groovy.json.*

 

def builder = new JsonBuilder()
 
        def root = builder{
            "data"(
                LkInfo.list().collect{ lkInfo ->
                [
                    "city":lkInfo.city,
                    "name":lkInfo.name
                    ]
                }
            )
        }

 

println  builder.toPrettyString();

 

结果如下：

 

{
    "data": [
        {
            "city": "太原",
            "name": "名称1"
        },
        {
            "city": "太原",
            "name": "名称2"
        }

   ]

}

 

代码2:

import groovy.json.* def ars=[["1":1,"2":2],"456","789"] def builder = new JsonBuilder()  //如同构建对象般  builder.pepole{      person {          firstName 'leng'          lastName 'feng'          //传入map          address1{                 city 'BeiJing'                  country 'China'                  zip 12345                 }          address2(                 city: 'Shanghai',                  country: 'China',                  zip: 12345                 )          married true          //传如list          conferences 'JavaOne', 'Gr8conf'          delegate."ars"(ars)     }  }  //以树形结构输出  println JsonOutput.prettyPrint(builder.toString())
