Incorrect constructor injection in XML Spring bean

Reports Spring <bean> using constructor-based dependency injection.

The inspection triggers when it can't find an appropriate constructor or factory method for <bean> with the configured <constructor-arg> tags and defined autowire policy.

Example:

    public class MyComponent {
    // constructor
    public MyComponent(MyBean bean) {}
    // factory method
    public static MyComponent getInstance(String name, int port) {
    }

    <beans>
      <bean class="beans.MyComponent" id="foo"> <!-- reports "No matching constructor found in class 'MyComponent" -->
         <constructor-arg ref="myBean"/>
         <constructor-arg value="123"/>
      </bean>

      <bean class="beans.MyComponent" factory-method="getInstance"> <!-- reports "No matching factory method found in class" -->
         <constructor-arg value="123"/>
      </bean>
    </beans>
