Mulesoft Java Connector Invoke Example
To invoke a Java method using the MuleSoft Java Connector, you can create a custom Java class with the desired method and then call that method from a MuleSoft flow using the Java Connector. Here’s a step-by-step example:
Step 1: Create a Java Class
Create a Java class with the method you want to invoke. Let’s say you want to create a simple class that performs a calculation. Here’s an example:
package com.example;
public class Calculator {
public int add(int a, int b) {
return a + b;
}
}
Step 2: Create a MuleSoft Project
In Anypoint Studio, create a new Mule project or open an existing one.
Step 3: Add Java Class to Your Project
Add the Java class you created in Step 1 to your Mule project. Place it in the appropriate package within your project’s src/main/java directory.
Step 4: Configure the Java Connector
In your Mule project’s XML configuration file (usually mule-config.xml), configure the Java Connector to use your custom Java class. Here’s an example:
<mule xmlns="http://www.mulesoft.org/schema/mule/core"
xmlns:java="http://www.mulesoft.org/schema/mule/java"
xmlns:spring="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd
http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd
http://www.mulesoft.org/schema/mule/java http://www.mulesoft.org/schema/mule/java/current/mule-java.xsd">
<!-- Configure the Java Connector to use your custom Java class -->
<java:config name="Java_Config" doc:name="Java" class="com.example.Calculator"/>
<!-- Define your Mule flow -->
<flow name="invokeJavaMethodFlow">
<!-- Invoke the 'add' method from the Java class -->
<java:invoke config-ref="Java_Config" method="add" doc:name="Invoke" >
<java:args>
<java:arg value="3" />
<java:arg value="4" />
</java:args>
</java:invoke>
<!-- Log the result -->
<logger message="Result: #[payload]" level="INFO" doc:name="Logger"/>
</flow>
</mule>
In the above configuration, we configure the Java Connector to use the com.example.Calculator class. Then, in the invokeJavaMethodFlow, we invoke the add method from the Calculator class and log the result.
Step 5: Run the Mule Application
Save your Mule configuration and run the Mule application in Anypoint Studio. You should see the result of invoking the Java method in the log.
