Mule Java组件和线程安全

Question

An excerpt from this http://www.mulesoft.org/documentation/display/current/Configuring+Java+Components is:

When you specify the class directly on the component or pooled-component element, the PrototypeObjectFactory is used by default, and a new instance is created for each invocation, or a new pooled component is created in the case of the PooledJavaComponent

And, I have configured a Java class as Mule Java component like below:

<component class="com.mycompany.SalesOrderProductsHandler" doc:name="Java" /> . The class SalesOrderProductsHandler has implemented org.mule.api.lifecycle.Callable and has one state variable named targetProductsIndex .

My question follows:

Will a new instance of com.mycompany.SalesOrderProductsHandler get created every time a new request comes?

Answer 1

The documentation is absolutely correct. With:

<component class="com.mycompany.SalesOrderProductsHandler" />

you will get a new instance of com.mycompany.SalesOrderProductsHandler for each invocation.
