Provide way in MVC Java config to modify rather than replace default HandlerExceptionResolvers [SPR-13931] #18503
Description
Bill Chen opened SPR-13931 and commented
Currently, if one configures a resolver with WebMvcConfigurerAdapter.configureHandlerExceptionResolvers(), the default ones will not be added. And since WebMvcConfigurationSupport.addDefaultHandlerExceptionResolvers() is not directly accessible, one has to copy code from that method to manipulate the defaults.
Fundamentally, this way of registering resolvers (by adding them to a list which is then used to build a HandlerExceptionResolverComposite) is really unnecessary because Spring MVC can use multiple HandlerExceptionResolver beans in the context anyways.
Can the default ones be exposed as normal beans with enough gaps in their default order instead?
Alternatively, at least provide a way to insert resolvers in between the defualt ones like the extendMessageConverters() method.
