问题执行springwebflow流关联视图未呈现

Question

我对使用spring-boot + primefaces和spring-webflow开发的应用程序有疑问。从日志中可以看到流已被记录并执行，但是未呈现与流相关的视图.DispatcherServlet似乎进入了根上下文。

这是我的pom文件：

这是我的流程配置类

package it.forgroup.dpmpilot.webflow.config;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.faces.config.AbstractFacesFlowConfiguration;

import org.springframework.webflow.executor.FlowExecutor;
import org.springframework.webflow.mvc.servlet.FlowHandlerAdapter;
import org.springframework.webflow.mvc.servlet.FlowHandlerMapping;

import it.forgroup.dpmpilot.exception.ExceptionListener;

@Configuration
public class WebFlowConfig extends AbstractFacesFlowConfiguration {


    @Bean(name="a")
    public FlowDefinitionRegistry flowRegistry() {
        return getFlowDefinitionRegistryBuilder()
                .setBasePath("/flows")
                .addFlowLocationPattern("/**/*.xml")
                .setFlowBuilderServices(flowBuilderServices())
                .build();
    }

    @Bean(name="b")
    public FlowBuilderServices flowBuilderServices() {
        return getFlowBuilderServicesBuilder()
                .setDevelopmentMode(true)
                .build();
    }

    @Bean(name="c")
    public FlowExecutor flowExecutor(ExceptionListener allExceptionListener) {
        return getFlowExecutorBuilder(flowRegistry())
                .addFlowExecutionListener(new FlowFacesContextLifecycleListener())
                .addFlowExecutionListener(allExceptionListener)
                .setMaxFlowExecutionSnapshots(0)
                .build();
    }

    @Bean("d")
    public FlowHandlerMapping flowHandlerMapping() {
        FlowHandlerMapping handlerMapping = new FlowHandlerMapping();
        handlerMapping.setOrder(-1);
        handlerMapping.setFlowRegistry(flowRegistry());
        return handlerMapping;
    }

    @Bean("e")
    public FlowHandlerAdapter flowHandlerAdapter(@Autowired ExceptionListener allExceptionListener) {
        JsfFlowHandlerAdapter adapter = new JsfFlowHandlerAdapter();
        adapter.setFlowExecutor(flowExecutor(allExceptionListener));
        return adapter;
}

}

请我需要帮助。
