將其轉換爲地圖第一：

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

然後使用MEL更新地圖

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

然後將其轉換回JSON當您準備：

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

另一種方法是使用Dataweave它可以很容易地滿足您的需求nd可以在運行時動態更改"status"的值，其中"status"要更改的元素

<dw:transform-message doc:name="Transform Message"> 
     <dw:set-payload><![CDATA[%dw 1.0 
      %output application/json 
      --- 
      { 
      product1: { 
       "addedBy": payload.product1.addedBy, 
       "addedDate": payload.product1.addedDate, 
       "campaignName": payload.product1.campaignName, 
       "status": "Unavailable" 
      }, 
      product2:{ 
       "addedBy": payload.product2.addedBy, 
       "addedDate": payload.product2.addedDate, 
       "campaignName": payload.product2.campaignName, 
       "status": "Unavailable" 
      }, 
      product3:{ 
       "addedBy": payload.product3.addedBy, 
       "addedDate": payload.product3.addedDate, 
       "campaignName": payload.product3.campaignName, 
       "status": "Unavailable" 
      } 

      } ]]></dw:set-payload> 
    </dw:transform-message>
