騾子 - 對象參數數據庫

Question

我有這個mule flow：

<?xml version="1.0" encoding="UTF-8"?> 

<mule xmlns:db="http://www.mulesoft.org/schema/mule/db" xmlns:json="http://www.mulesoft.org/schema/mule/json" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <spring:beans> 

     <spring:bean id="propertyConfigurer" 
      class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
      <spring:property name="locations"> 
       <spring:list> 
        <spring:value>configSQL.properties</spring:value> 
       </spring:list> 
      </spring:property> 
     </spring:bean> 

    </spring:beans> 

    <db:generic-config name="BBDD_USER" doc:name="Generic Database Configuration" driverClassName="net.sourceforge.jtds.jdbc.Driver" 
    url="${sql.url}/${sql.database};user=${sql.username};password=${sql.password}"/> 

    <flow name="sincro-sql" doc:name="sincro-sql"> 

     <http:inbound-endpoint exchange-pattern="one-way" host="localhost" port="8042" doc:name="HTTP"/> 

     <logger message="#[message.payloadAs(java.lang.String)]" level="INFO" doc:name="JSON"/> 

     <json:json-to-object-transformer doc:name="JSON to Object" returnClass="json.database.object.Data"/> 

     <db:stored-procedure config-ref="BBDD_USER" doc:name="Data" source="json.database.object.Data" streaming="true"> 
      <db:parameterized-query><![CDATA[{ CALL dbo.ExecSQL(:table_name, :field_name) }]]></db:parameterized-query> 
      <db:in-param name="field_name" type="VARCHAR" value="field_test"/> 
      <db:in-param name="table_name" type="VARCHAR" value="table_test"/> 
     </db:stored-procedure> 

    </flow> 
</mule> 

它收到一個JSON我變換與類，它包含反對：

@JsonAutoDetect  
public class Data{ 

     private String table_name; 
     private String field_name; 

     public void setTableName(String table_name) { 
      this.table_name= table_name; 
     } 

     public String getTableName() { 
      return table_name; 
     } 

     public void setFieldName(String field_name) { 
      this.field_name= field_name; 
     } 

     public String getFieldName() { 
      return field_name; 
     } 
    } 

最後，我打電話給我的數據庫。我怎樣才能分配，例如財產關於從類到參數在數據庫元素表名？

例如，

<db:in-param name="table_name" type="VARCHAR" value="PROPERTY OF CLASS"/>

使用MEL（騾表達語言特點）和標準的Java方法調用。由於數據是您的有效載荷，請使用＃[payload.table_name] MEL將自動爲該字段使用getter。
