在Spring Boot中使用多视图解析器时，为什么JSP页面没有显示？

Question

我为PDF，Excel和用于JSP文件的InternalResourceViewResolver添加了多视图解析器。 PDF和Excel解析器工作正常，但是当我调用/ test调用我的测试（test.jsp）时，我看到一个空白页。但是，当我删除其他解析器或禁用我的webconfig时，test.jsp（/ test）可以很好地加载。

以下是我在调用/ test（绑定到测试控制器和test.jsp）时看到的错误：

2018-08-11 23:43:06.191 ERROR 12136 --- [nio-9090-exec-1] o.s.boot.web.support.ErrorPageFilter     : Cannot forward to error page for request [/test] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false

此外，以下是我的webconfig负责添加多个解析器（pdf，excel和jsp页面）：

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer
                .defaultContentType(MediaType.APPLICATION_JSON)
                .favorPathExtension(true);
    }

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    /*
     * Configure ContentNegotiatingViewResolver
     */
    @Bean
    public ViewResolver contentNegotiatingViewResolver(ContentNegotiationManager manager) {
        ContentNegotiatingViewResolver resolver = new ContentNegotiatingViewResolver();
        resolver.setContentNegotiationManager(manager);

        // Define all possible view resolvers
        List<ViewResolver> resolvers = new ArrayList<>();

        resolvers.add(internalResourceViewResolver());
        resolvers.add(pdfViewResolver());
        resolvers.add(excelViewResolver());

        resolver.setViewResolvers(resolvers);
        return resolver;
    }

    @Bean
    public ViewResolver internalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();

        resolver.setPrefix("/WEB-INF/jsp");
        resolver.setSuffix(".jsp");
        return resolver;
    }

    /*
     * Configure View resolver to provide XLS output using Apache POI library to
     * generate XLS output for an object content
     */
    @Bean
    public ViewResolver excelViewResolver() {
        return new ExcelViewResolver();
    }

    /*
     * Configure View resolver to provide Pdf output using iText library to
     * generate pdf output for an object content
     */
    @Bean
    public ViewResolver pdfViewResolver() {
        return new PdfViewResolver();
    }
}
