Invoke Component in Mule | Call Java Class in Mule
Invoke component is used to invoke java class in Mule.
flow of Invoke component :
First of all write a simple java class containing a method to perform an operation.
We have TestInvoke.java class located in src/main/java
package com.test;
public class TestInvoke {
String str = null;
public String a(String str) {
System.out.println("Hello Himanshu" + " " + str);
this.str = str;
return "Hello Himanshu" + ' ' + str;
}
}
It will take payload which is passed as argument in method 'a'.
Invoke component configuration :
We have to give Bean defination of our java class in configuration XML.
<spring:beans>
<spring:bean class="com.test.TestInvoke" name="testInvoke"></spring:bean>
</spring:beans>
