将应用程序迁移到Spring 5并部署到Websphere 8.5.5之后，我们发现了此异常

我们已经能够看到在调用getObject（）方法时定义的任何bean工厂中会发生什么

@Bean
    public ContentNegotiatingViewResolver viewResolver() {
        ContentNegotiatingViewResolver viewResolver = new ContentNegotiatingViewResolver();
        viewResolver.setOrder(-1);
        viewResolver.setContentNegotiationManager(contentNegotiationManager().getObject());
        viewResolver.setDefaultViews(defaultViews());
        viewResolver.setViewResolvers(viewResolvers());
        return viewResolver;
    }

执行此行时会发生异常

viewResolver.setContentNegotiationManager(contentNegotiationManager().getObject());

与4.3.x春季版本相同的应用程序不会发生。
