mule在json中动态插入数据

在mule中，上面的json是我的输入数据。我想在mule中更改运行时的状态值。有人能告诉它怎么走吗？

先把它转换成地图：

{
  "product1": {
     "addedBy": "1014",
    "addedDate": "1429681809598",
    "campaignName": promotion,
    "status": "Available"

  },
    "product2": {
       "addedBy": "1015",
      "addedDate": "1429681809598",
      "campaignName": bulkoffer,
      "status": "Available"

  },
    "product3": {
         "addedBy": "1015",
        "addedDate": "1429681809598",
        "campaignName": premiumoffer,
        "status": "Available"        
    }    
    }

然后使用MEL更新贴图

<json:object-to-json-transformer returnClass="java.util.HashMap" />

准备好后，将其转换回json：

<expression-component>payload.product1.status = 'Unavailable'</expression-component>

另一种方法是使用它，它可以很容易地满足您的需求，并且可以在运行时动态地更改status的值，无论您想要更改哪个statuselement

<json:object-to-json-transformer />
