With value referenced from property file in XML configuration, setter selection can be random in case of overloaded setter methods (e.g. on SimpleClientHttpRequestFactory)

[dima-sarin]

Affects: 6.1.4

Summary
With value referenced from property file in XMLConfig, if a bean-defined class has an overloaded setter, an exception may be thrown at runtime.

I checked the logs and found that the wrong setter was used.
Specifically, I found that the setter was changing each time the application was launched.

This behaviour occurs in XMLConfig

I found this behaviour in the bean definition of SimpleClientHttpRequestFactory.
Here is an example of a Bean definition.

<bean id="beanId" class="org.springframework.http.client.SimpleClientHttpRequestFactory">
        <property name="connectTimeout">
            <value type="int">${connectionTimeout}</value>
        </property>
        <property name="readTimeout">
            <value type="int">${readTimeout}</value>
        </property>
    </bean>

SimplyClientHttpRequestFactory has overload setter of Duration and int such as setConnectTimeout method, setReadTimeout method.

This is a follow-up to #32159 which turned out to be incomplete since it did not take type conversion for a fallback method into account.

Thank you, @jhoeller !

FYI for anyone who is experiencing this issue, the following bean definition worked fine for me in 6.1.4 version

<bean id="beanId" class="org.springframework.http.client.SimpleClientHttpRequestFactory">
        <property name="connectTimeout" value="#{T(java.time.Duration).ofMillis(${connectionTimeout})}"/>
        <property name="readTimeout" value="#{T(java.time.Duration).ofMillis(${readTimeout})}"/>
    </bean>
