Continue traveling in the XML ocean of mule.
Send a map message to a VM: queue. The mule dynamically executes the SQL statement based on the map information and returns data. The SELECT query mule returns map data by default.
Configuration file:
<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <mule xmlns = "http://www.mulesource.org/schema/mule/core/2.1" <br/> xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" <br/> xmlns: JDBC = "http://www.mulesource.com/schema/mule/jdbc/2.1" <br/> xmlns: spring = "http://www.springframework.org/schema/beans" <br/> xmlns: Vm = "http://www.mulesource.org/schema/mule/vm/2.1" <br/> xsi: schemalocation = "<br/> http://www.mulesource.com/schema/mule/jdbc/2.1 H Ttp: // www.mulesource.com/schema/mule/jdbc/2.1/mule-jdbc-ee.xsd <br/> http://www.mulesource.org/schema/mule/core/2.1 http://www.mulesource.org/schema/mule/core/2.1/mule.xsd http://www.springframework.org/schema/beans <br/> http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.mulesource.org/schema/mule/vm/2.1 http://www.mulesource.org/schema/mule/vm/2.1/mule-vm.xsd <br/> <br /> <Spring: bean id = "datasource" <br/> class = "org. apache. commons.

NOTE: If mule uses 2.1, the namespase Suffix of JDBC transport is com, instead of org. If an error is written, the IDE will not prompt, and the program exception is also very strange. I had to wait for an afternoon :(
Test procedure:
Public class mymuleclienttest <br/>{< br/> Public static void main (string [] ARGs) throws muleexception <br/>{< br/> // create mule <br/> mulecontext; <br/> string Config = "my-mule-jdbc-config.xml "; <br/> mulecontext = new defaultmulecontextfactory (). createmulecontext (config); <br/> mulecontext. start (); <br/> // creat mule client <br/> muleclient client = new muleclient (); <br/> map = new hashmap (); <br/> map. put ("firstname", "Feng"); <br/> mulemessage response = client. send ("VM: // query", MAP, null); <br/> system. out. println ("response =" + response. getpayload (); <br/>}< br/>}
The executed SQL is:
Select first_name, last_name from app_user where first_name = "Feng"

Insert execution is similar. You only need to modify it as follows:
<Outbound> <br/> <pass-through-router> <br/> <JDBC: outbound-endpoint querykey = "insertuser" synchronous = "true"/> <br/> </pass-through-router> <br/> </outbound>

It seems that the JDBC transtort of mule is the ibatis of the crying version,
