spring-boot - Primfaces 6.2 使用 Spring Boot 2.1 上传文件

Question

我正在尝试使用 Primefaces 6.2 和 Spring Boot 2.1 上传文件我想我已经配置好了所有东西，但我无法上传文件。当我尝试上传文件时，我看到页面上正在加载，但在控制台中我没有日志，而且我的调试器不会在处理函数的断点处停止。

我的 .xhtml 表单：

<h:form id="uploadForm" enctype="multipart/form-data">
        <p:fileUpload value="#{estimateState.file}" skinSimple="true" label="Wybierz plik"
                      update="growl" mode="advanced" auto="true"
                      fileUploadListener="#{estimateController.handleFileUpload}"/>
</h:form>

文件处理程序

public void handleFileUpload(FileUploadEvent event) {
    informationMessage(getState().getFile().getFileName() + " is uploaded.");
}

初始化 PrimeFaces 的 Bean

@Bean
public FilterRegistrationBean primeFacesFileUploadFilter(@Autowired ServletRegistrationBean<FacesServlet> facesServletServletRegistrationBean) {
    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(new org.primefaces.webapp.filter.FileUploadFilter());
    registration.setName("primeFacesFileUploadFilter");
    registration.setDispatcherTypes(DispatcherType.FORWARD);
    registration.setServletNames(Collections.singleton(FACES_SERVLET_NAME));
    registration.setServletRegistrationBeans(Collections.singleton(facesServletServletRegistrationBean));
    return registration;
}

@Override
public void setServletContext(ServletContext servletContext) {
    servletContext.setInitParameter("facelets.DEVELOPMENT", Boolean.TRUE.toString());

    servletContext.setInitParameter("javax.faces.DEFAULT_SUFFIX", ".xhtml");
    servletContext.setInitParameter("javax.faces.PROJECT_STAGE", "Development");
    servletContext.setInitParameter("javax.faces.FACELETS_REFRESH_PERIOD", "1");
    servletContext.setInitParameter("javax.faces.FACELETS_LIBRARIES", "/WEB-INF/springsecurity.taglib.xml");
    servletContext.setInitParameter("javax.faces.FACELETS_SKIP_COMMENTS", Boolean.TRUE.toString());

    servletContext.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());

    servletContext.setInitParameter("primefaces.CLIENT_SIDE_VALIDATION", Boolean.TRUE.toString());
    servletContext.setInitParameter("primefaces.THEME", "ui-lightness");
    servletContext.setInitParameter("primefaces.UPLOADER", "commons");
    servletContext.setInitParameter("primefaces.MOVE_SCRIPTS_TO_BOTTOM", Boolean.TRUE.toString());
}

@Bean
public ServletRegistrationBean<FacesServlet> facesServletServletRegistrationBean() {
    ServletRegistrationBean<FacesServlet> servletRegistrationBean = new ServletRegistrationBean(new FacesServlet(), "*.xhtml");
    servletRegistrationBean.setLoadOnStartup(1);
    servletRegistrationBean.setName(FACES_SERVLET_NAME);
    return servletRegistrationBean;
}

我还在我的 pom.xml 文件中添加了公共依赖项

<dependency>
        <groupId>commons-fileupload</groupId>
        <artifactId>commons-fileupload</artifactId>
        <version>1.3</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
    <dependency>
        <groupId>commons-io</groupId>
        <artifactId>commons-io</artifactId>
        <version>2.6</version>
    </dependency>

请帮我！提前致谢 ：）

我得到这样的东西：

我的配置 bean 有问题下面正确配置的 bean：

 @Bean
public FilterRegistrationBean primeFacesFileUploadFilter(@Autowired ServletRegistrationBean<FacesServlet> facesServletServletRegistrationBean) {
    FilterRegistrationBean registration = new FilterRegistrationBean(new org.primefaces.webapp.filter.FileUploadFilter(), facesServletServletRegistrationBean);
    registration.setName("primeFacesFileUploadFilter");
    registration.addUrlPatterns("/*");
    registration.setDispatcherTypes(DispatcherType.FORWARD, DispatcherType.REQUEST);
    return registration;
}

@Bean
public FacesServlet facesServlet() {
    return new FacesServlet();
}

@Bean
public ServletRegistrationBean<FacesServlet> facesServletServletRegistrationBean(@Autowired FacesServlet facesServlet) {
    ServletRegistrationBean<FacesServlet> servletRegistrationBean = new ServletRegistrationBean(facesServlet, "*.xhtml");
    servletRegistrationBean.setLoadOnStartup(1);
    servletRegistrationBean.setName(FACES_SERVLET_NAME);
    return servletRegistrationBean;
}

我需要添加 facesServlet bean，并且在 FilterRegistrationBean 中使用了两个参数构造函数。我也删除了这一行

registration.setServletRegistrationBeans(Collections.singleton(facesServletServletRegistrationBean));
