丰富的中介者要插入到消息正文中的对象类型无效 [英] Enrich mediator Invalid Object type to be inserted into message body

问题描述

ERROR: Enrich mediator Invalid Object type to be inserted into message body

ERROR: Enrich mediator Invalid Object type to be inserted into message body

尝试丰富消息时，这里是代理配置:

when trying to enrich the message, here is the proxy configuration:

<proxy xmlns="http://ws.apache.org/ns/synapse" name="Database" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
   <target>
      <inSequence>
         <dblookup>
            <connection>
               <pool>
                  <password>1234</password>
                  <user>root</user>
                  <url>jdbc:mysql://localhost:3306/new_db</url>
                  <driver>com.mysql.jdbc.Driver</driver>
               </pool>
            </connection>
            <statement>
               <sql>select * from users where name="rik"</sql>
               <result name="client_expiration" column="expiration" />
               <result name="client_id" column="id" />
               <result name="client_name" column="name" />
            </statement>
         </dblookup>
         <log level="custom">
            <property name="returned value for client_expiration is :" expression="get-property('client_expiration')" />
            <property name="returned value for client_id is :" expression="get-property('client_id')" />
            <property name="returned value for client_name is :" expression="get-property('client_name')" />
         </log>
         <property name="property1" expression="get-property('client_expiration')" scope="default" />
         <enrich>
            <source type="property" property="property1" />
            <target type="body" action="sibling" />
         </enrich>
         <sequence key="getback" />
      </inSequence>
   </target>
</proxy>

和序列配置(但应该不是这里的问题):

and the sequence configuration (but should not be here the problem):

<sequence xmlns="http://ws.apache.org/ns/synapse" name="getback">
   <header name="To" action="remove" />
   <property name="RESPONSE" value="true" scope="default" />
   <send />
   <log level="full" />
</sequence>

非常感谢！

EDIT:日志有效，但消息无效.这是日志文件:

EDIT: the log works but the message doesn't. This is the log file:

推荐答案

像这样丰富 mediator 并尝试

Have enrich mediator like this and try

<enrich>
            <source type="custom" xpath="get-property('property1')"/>
            <target type="body" action="sibling"/>
        </enrich>
