Apache Camel: Instantiate a class using its multiparameter constructor - apache-camel

Question

How do I go about invoking a method on a class object by having it instantiated with its multiparameter constructor in a Camel route using Spring DSL with bean binding first?
For example this one:
package org.my.package;
public class SomeClass {
public SomeClass() {}
public SomeClass(String param1, String param2) {
...
}
public void doSomething() {
}
}
Method invokation using the default (no-args) constructor is clear:
<to uri="bean:org.my.package.SomeClass?method=doSomething" />

You can instantiate a class instance only using default no-argument constructor. But you can use bean properties for set class fields.
Bean
<bean class="org.my.pack.SomeClass" factor:bean-type="DEFAULT"
id="SomeClass" name="SomeClass">
<property name="param1" value="Value1"/>
<property name="param2" value="Value2"/>
</bean>
Class
package org.my.pack;
public class SomeClass {
public String param1;
public String param2;
public String getParam1() {
return param1;
}
public void setParam1(String param1) {
this.param1 = param1;
}
public String getParam2() {
return param2;
}
public void setParam2(String param2) {
this.param2 = param2;
}
public String doSomething() {
return "Param1 - " + param1 + " Param2 - " + param2;
}
public static void main(String[] args) {
}
}
Or you can also use annotations for method parameters and take values from headers for example (https://camel.apache.org/manual/latest/parameter-binding-annotations.html)
public String doSomething(#Header("param1") String param1, #Header("param2") String param2) {
return "Param1 - " + param1 + " Param2 - " + param2;
}
