Overriding singleton bean

[hsn]

I found that i can not register bean which already exists in xml:

Error: java.lang.IllegalStateException: Could not register object [Configuration: core-default.xml, core-site.xml, mapred-default.xml, mapred-site.xml, yarn-default.xml, yarn-site.xml, hdfs-default.xml, hdfs-site.xml, job.xml] under bean name 'hadoopConfiguration': there is already object [org.springframework.data.hadoop.configuration.Conf igurationFactoryBean@7e4e194f]

How to solve this? is there some way to unregister bean at runtime and then register a new one under same name?

changed code to:
/* register hadoop configuration */
springContext.getBeanFactory().destroyBean("hadoop Configuration", springContext.getBean("hadoopConfiguration"));
springContext.getBeanFactory().registerSingleton(" hadoopConfiguration", conf);

but still does not work

Error: java.lang.IllegalStateException: Could not register object [Configuration: core-default.xml, core-site.xml, mapred-default.xml, mapred-site.xml, yarn-default.xml, yarn-site.xml, hdfs-default.xml, hdfs-site.xml, job.xml] under bean name 'hadoopConfiguration': there is already object [org.springframework.data.hadoop.configuration.Conf igurationFactoryBean@27b104d7] bound

have you tried

public void removeBeanDefinition(String beanName) instead of destroyBean.

i am using ClassPathXmlApplicationContext and it does not have this method.
