== Why is this an issue?

include::../description.adoc[]

=== Noncompliant code example

With a maximum number of 4 parameters:

[source,java]
----
public void doSomething(int param1, int param2, int param3, String param4, long param5) {
...
}
----

=== Compliant solution

[source,java]
----
public void doSomething(int param1, int param2, int param3, String param4) {
...
}
----

=== Exceptions

Methods annotated with :

* Spring's ``++@RequestMapping++`` (and related shortcut annotations, like ``++@GetRequest++``)
* JAX-RS API annotations (like ``++@javax.ws.rs.GET++``)
* Bean constructor injection with ``++@org.springframework.beans.factory.annotation.Autowired++``
* CDI constructor injection with ``++@javax.inject.Inject++``
* ``++@com.fasterxml.jackson.annotation.JsonCreator++``
* Micronaut's annotations (like ``++@io.micronaut.http.annotation.Get++``)

may have a lot of parameters, encapsulation being possible. Such methods are therefore ignored.

Also, if a class annotated as a Spring component (like ``++@org.springframework.stereotype.Component++``) has a single
constructor, that constructor will be considered ``++@Autowired++`` and ignored by the rule.

!RequestMapping Annotation Not Ignored.png!


Hi, 

I have been using the SonarJava 5.8 updated plugin and I still see RequestMapping annotation is not being ignored by SonarQube. Attached is the image of code snippet(sorry I have to hide the names due to the company policies). Can someone tell me how to make it work?  

Thanks
