Avoid ambiguous property warning for setter methods with multiple parameters [SPR-13349]

[spring-projects-issues]

Tristan Hill opened SPR-13349 and commented

I'm getting this warning on application initialization:

WARN  org.springframework.beans.GenericTypeAwarePropertyDescriptor  - Invalid JavaBean property 'endpoint' being accessed! Ambiguous write methods found next to actually used [public void com.amazonaws.AmazonWebServiceClient.setEndpoint(java.lang.String) throws java.lang.IllegalArgumentException]: [public void com.amazonaws.AmazonWebServiceClient.setEndpoint(java.lang.String,java.lang.String,java.lang.String)]

The bean configuration is:

<bean class="com.amazonaws.services.s3.AmazonS3Client" id="s3Client">
    <constructor-arg index="0" ref="awsDefaultCredentialsProviderChain"/>
    <constructor-arg index="1" ref="awsClientConfiguration"/>
    <property name="endpoint" value="value"/>
</bean>

Is the method really ambiguous since only a single string parameter is provided as argument?

Strictly speaking, such an overloaded method is not a valid JavaBean property even in case of a different number of parameters. However, point taken that it is not an issue in practice, since we'll always pick the single-arg method anyway.

I'll try to reduce that warning check to single-arg methods for 4.2.1.

Resolved for 4.2.1 now, and also scheduled for a backport to 4.1.8.
