Question

我试图在嵌入式tomcat中将spring boot与JSF集成，但没有运气，我尝试了两种方法，一种是使用web.xml，另一种是使用Java配置。在这两种情况下，xhtml页面都没有被渲染，而是渲染了一个空白页面。以下是配置。

的pom.xml

src / main / resources / META-INF目录中的

faces.config

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

在src / main / webapp / META-INF中使用的context.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Resource name="BeanManager" auth="Container"
        type="javax.enterprise.inject.spi.BeanManager" factory="org.jboss.weld.resources.ManagerObjectFactory" />

将Index.html移至src / main / resources / META-INF / resources 的的index.xhtml

@SpringBootApplication
@ComponentScan(basePackages={"com.kp.swasthik.bjsf"})
public class KpSbBjsfApplication extedns SpringBootServletInitializer{


    public static void main(String[] args) {
        SpringApplication.run(KpSbBjsfApplication.class, args);
    }    

     @Override
     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
    return application.sources(KpSbBjsfApplication.class);
  } 

  @Bean
public ServletRegistrationBean facesServletRegistration() {

    ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new FacesServlet(), "*.xhtml");
    servletRegistrationBean.addUrlMappings("/faces/*");
    servletRegistrationBean.setLoadOnStartup(1);
    return servletRegistrationBean;
}

@Bean
public ServletListenerRegistrationBean<ConfigureListener> jsfConfigureListener() {
    return new ServletListenerRegistrationBean<ConfigureListener>(new ConfigureListener());
}

@Bean
@ConditionalOnMissingBean
public RequestContextListener getRequestContextListener() {
    return new RequestContextListener();
}
}

和servlet上下文init类。

public class ServletCustmContextInitializer implements ServletContextInitializer {

    @Override
    public void onStartup(ServletContext jsfServlet) throws ServletException {
   jsfServlet.setInitParameter("com.sun.faces.forceLoadConfiguration", Boolean.TRUE.toString());
    jsfServlet.setInitParameter("javax.faces.PARTIAL_STATE_SAVING_METHOD", "true");
    jsfServlet.setInitParameter("javax.faces.PROJECT_STAGE", "Development");
    jsfServlet.setInitParameter("facelets.DEVELOPMENT", "true");
    jsfServlet.setInitParameter("javax.faces.FACELETS_REFRESH_PERIOD", "1");
    jsfServlet.setInitParameter("primefaces.CLIENT_SIDE_VALIDATION", "true");
    jsfServlet.setInitParameter("javax.faces.DEFAULT_SUFFIX", ".xhtml");
    jsfServlet.setInitParameter("primefaces.THEME", "bootstrap");

    }

}

我设法调出jsf-spring启动配置，但现在JSF注释不起作用。如果我手动将注释添加到faces-config.xml，则托管注释可以正常工作。我甚至添加了metadata-complete =＆＃34; false＆＃34;所以jsf可悲地扫描注释它不起作用

恰巧我写了一篇关于如何做到这一点的教程。您可以在GitHub上find it here以及功能齐全的maven演示项目。

这里的关键问题是Spring Boot是自以为是并且更喜欢java-config，因此配置是从java代码注入的，而Tomcat要求web.xml只是作为一个舒适的毯子存在;它没用过。

不要使用Omnifaces，它需要CDI并且在我的尝试中似乎不可能在嵌入式Tomcat中表现。还有其他可以使用的工具，它们运行良好，在我的教程中，我已经配置了Rewrite，如何做到这一点并不明显。
