我如何使用 spring 引导创建 JSF 应用程序

Question

我正在尝试创建一个 JSF Spring 引导应用程序。这是我编码的内容：

我的pom.xml:

面孔配置：

<?xml version="1.0" encoding="UTF-8"?>
<faces-config xmlns="http://xmlns.jcp.org/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
        http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd"
              version="2.2">
    <application>
        <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
    </application>
</faces-config>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" version="3.1">
    <servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <listener>
        <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
    </listener>
</web-app>

Spring启动应用程序：

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan({"tp.spring.mvc.rest"})
public class TpSpringMvcRestApplication extends SpringBootServletInitializer  implements CommandLineRunner{
    
    private static Logger LOGGER = Logger.getLogger(TpSpringMvcRestApplication.class.getName());
    
    @Autowired
    private UserService userService;

    public static void main(String[] args) {
        SpringApplication.run(TpSpringMvcRestApplication.class, args);
    }
    
    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        FacesServlet servlet = new FacesServlet();
        return new ServletRegistrationBean(servlet, "*.jsf");
    }
    
    @Bean
    public FilterRegistrationBean rewriteFilter() {
        FilterRegistrationBean rwFilter = new FilterRegistrationBean(new RewriteFilter());
        rwFilter.setDispatcherTypes(
                EnumSet.of(DispatcherType.FORWARD, DispatcherType.REQUEST, DispatcherType.ASYNC, DispatcherType.ERROR));
        rwFilter.addUrlPatterns("/*");
        return rwFilter;
    }

控制器：

@Scope(value = "session")
@Component(value = "userController") // Name of the bean in Spring IoC
@ELBeanName(value = "userController") // Name of the bean used by JSF
@Join(path = "/", to = "/login.jsf")
public class UserController {
        
    public void doLogin() { 
        System.out.println("HELLO");
    }
}

XHTML 登录页面：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

    <ui:composition xmlns="http://www.w3.org/1999/xhtml"

        xmlns:h="http://java.sun.com/jsf/html"
        xmlns:ui="http://java.sun.com/jsf/facelets"
        template="/template/template.xhtml">
        <ui:param name="page_name" value="Connexion" />
        <ui:define name="menu">
            <h:form id="form">
                <b>Connexion</b>
                <h:panelGrid columns="2">
                    <h:outputText value="Login (Email)" />
                    <h:commandButton id="btn" value="Connexion"
                        action="#{userController.doLogin()}" />
                </h:panelGrid>
            </h:form>
        </ui:define>
    </ui:composition>

问题是，当我点击连接按钮时，控制器中的方法没有被调用，我收到一个 Whitelabel 错误页面。

我该如何解决这个问题？

你能试着改变一下吗:

return new ServletRegistrationBean(servlet, "*.xhtml");
