web.xml中的上下文参数值将被忽略

Question

我一直想知道为什么没有应用primefaces主题并且永远无法修复它。今天，我发现，当我使用与web.xml中相同的内容向我的应用程序添加Bean“ ServletContextInitializer”时，它可以工作。我读到一些app.properties可能会覆盖设置的内容吗？我有一个application.properties，但仅用于数据库和jpa / hibernate。

应用程序：

@EnableAutoConfiguration
@ComponentScan({ "de.develop.telefonbuch" })
public class Application extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public FilterRegistrationBean<RewriteFilter> rewriteFilter() {
        FilterRegistrationBean<RewriteFilter> rwFilter = new FilterRegistrationBean<RewriteFilter>(new RewriteFilter());
        rwFilter.setDispatcherTypes(
                EnumSet.of(DispatcherType.FORWARD, DispatcherType.REQUEST, DispatcherType.ASYNC, DispatcherType.ERROR));
        rwFilter.addUrlPatterns("/*");
        return rwFilter;
    }

    @Bean
    public ServletContextInitializer servletContextCustomizer() {
        return new ServletContextInitializer() {
            @Override
            public void onStartup(ServletContext sc) throws ServletException {
                sc.setInitParameter(Constants.ContextParams.THEME, "afternoon");
                sc.setInitParameter(Constants.ContextParams.FONT_AWESOME, "false");
                sc.setInitParameter(ProjectStage.PROJECT_STAGE_PARAM_NAME, ProjectStage.Development.name());
            }
        };
    }

    @Bean
    public ServletRegistrationBean<FacesServlet> servletRegistrationBean() {
        FacesServlet servlet = new FacesServlet();
        return new ServletRegistrationBean<FacesServlet>(servlet, "*.jsf");
    }

}

我的web.xml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
