Cannot change HTTP accept header - use a different locale resolution strategy

Probably you do not have any bean  defined as "localeResolver" because by default AcceptHeaderLocaleResolver is implemented by spring which does not allow locale changed by setLocale() method. So you need to check if you have defined a bean for "localeResolver". You can do it like

@Bean
public LocaleResolver localeResolver(){}

Or

@Bean(name="localeResolver")
public LocaleResolver setupLocaleResolver(){}
