由于要存储整个JSON，因此无需将其反序列化为一个对象:我建议您将HTTP流传输的有效负载简单地转换为java.lang.String并将其原样插入数据库.

Since you want to store the whole JSON, there is no need to deserialize it as an object: I suggest you simply transform the HTTP-streamed payload into a java.lang.String and insert it as-is in the DB.

这将是这样的:

<jdbc:postgresql-data-source name="PostgreSQL_Data_Source"
    user="username" password="pwd" url="jdbc:postgresql://localhost:5432/TestDB"
    transactionIsolation="UNSPECIFIED" doc:name="PostgreSQL Data Source" />

<jdbc:connector name="PostgreSQL_Connector" dataSource-ref="PostgreSQL_Data_Source"
    validateConnections="true" queryTimeout="-1" pollingFrequency="0"
    doc:name="Database">
    <jdbc:query key="InsertRecord"
        value="INSERT INTO &quot;AnotherJSonTable&quot;(&quot;StoreJsonObject&quot;) VALUES (CAST(#[message.payload] AS json))" />
</jdbc:connector>

<flow name="testRestFlow1" doc:name="testRestFlow1">
    <http:inbound-endpoint exchange-pattern="request-response"
        address="http://localhost:8082/index.html" doc:name="HTTP" />
    <http:rest-service-component httpMethod="GET"
        serviceUrl="http://localhost:35798/RestServiceImpl.svc/json/567" />
    <object-to-string-transformer />
    <jdbc:outbound-endpoint exchange-pattern="one-way"
        queryKey="InsertRecord" queryTimeout="-1" connector-ref="PostgreSQL_Connector"
        doc:name="Database" />
</flow>
