问题

我有一个使用spring-mvc 5.1.8.RELEASE和thymeleaf 3.0.11.RELEASE-junit和log4j的简单动态Web应用程序。

我的项目是通过xml文件配置的

当我启动我的应用程序时，我得到了错误消息：

Request processing failed; nested exception is java.lang.IllegalStateException: ApplicationObjectSupport instance [org.thymeleaf.spring5.view.ThymeleafView@54e2c72d] does not run in an ApplicationContext

我搜索了类似的内容，但是我没有找到-也许我使用了错误的搜索词？

设置

我使用spring-mvc和thymeleaf设置了一个“简单”的maven-java-web-project。当前它由两个控制器（StartController和ErrorController），一个拦截器，两个jsp（start.jsp和error.jsp-用于测试目的），两个html文件（{ {1}}和start.html），error.html，web.xml和pom。

设置-web.xml： 

spring-servlet.xml

设置-spring-servlet.xml： 

<?xml version="1.0" encoding="UTF-8"?>
<web-app
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"

设置-ErrorController（spring-mvc jsp） 

package de.cmr.app.controller;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.servlet.View;
import org.thymeleaf.spring5.view.ThymeleafView;

@Controller("StartController")
public class StartController {
    private static final Logger LOG = LogManager.getLogger(StartController.class);

    @GetMapping("/")
    public View start() {
        final ThymeleafView view = new ThymeleafView("start");
        return view;
    }
}

设置-拦截器 

package de.cmr.app.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller("ErrorController")
public class ErrorController {
    @GetMapping("/error")
    public ModelAndView error() {
        final ModelAndView modelAndView = new ModelAndView("error");
        modelAndView.addObject("caption", "WebAppThymeleaf");
        return modelAndView;
    }
}

逻辑-应该发生什么

  1. 用户启动应用
  2. 拦截器应将用户代理及其CPU打印到控制台
  3. ，应该在package de.cmr.app.interceptors; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; public class AppMvcInterceptor implements HandlerInterceptor { @Override public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response, final Object handler, final Exception ex) throws Exception { // TODO Auto-generated method stub HandlerInterceptor.super.afterCompletion(request, response, handler, ex); } @Override public void postHandle(final HttpServletRequest request, final HttpServletResponse response, final Object handler, final ModelAndView modelAndView) throws Exception { // TODO Auto-generated method stub HandlerInterceptor.super.postHandle(request, response, handler, modelAndView); } @Override public boolean preHandle(final HttpServletRequest request, final HttpServletResponse response, final Object handler) throws Exception { System.out.println("User-Agent: " + request.getHeader("user-agent")); System.out.println("User-Agent-CPU: " + request.getHeader("ua-cpu")); return HandlerInterceptor.super.preHandle(request, response, handler); } } 上通过百里香（start.html）欢迎使用

逻辑-实际情况

  1. 用户启动应用
  2. 拦截器将用户代理及其CPU打印到控制台
  3. StartController被称为
  4. StartController#start()如期返回StartController#start()
  5. ThymeleafView抛出ThymeleafView#render()
  6. 然后通过spring-mvc jsp（IllegalStateException）将用户引向error.jsp

我的问题

我在做什么错了？

我的配置出了什么问题？

编辑-2019-08-05

根据建议，我尝试了Spring Initializer

我还更改了Juli 31, 2019 6:14:10 NACHM. org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [spring] in context with path [/de.cmr.app.web.spring.thymeleaf] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: ApplicationObjectSupport instance [org.thymeleaf.spring5.view.ThymeleafView@54e2c72d] does not run in an ApplicationContext] with root cause java.lang.IllegalStateException: ApplicationObjectSupport instance [org.thymeleaf.spring5.view.ThymeleafView@54e2c72d] does not run in an ApplicationContext at org.springframework.context.support.ApplicationObjectSupport.getApplicationContext(ApplicationObjectSupport.java:146) at org.springframework.web.context.support.WebApplicationObjectSupport.getWebApplicationContext(WebApplicationObjectSupport.java:109) at org.springframework.web.context.support.WebApplicationObjectSupport.getServletContext(WebApplicationObjectSupport.java:133) at org.thymeleaf.spring5.view.ThymeleafView.renderFragment(ThymeleafView.java:198) at org.thymeleaf.spring5.view.ThymeleafView.render(ThymeleafView.java:189) at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1371) at org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1117) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:1056) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:942) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:1005) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:897) at javax.servlet.http.HttpServlet.service(HttpServlet.java:634) at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:882) at javax.servlet.http.HttpServlet.service(HttpServlet.java:741) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:231) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:53) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.logging.log4j.web.Log4jServletFilter.doFilter(Log4jServletFilter.java:71) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:166) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:200) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:96) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:490) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:139) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:92) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:74) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:343) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:408) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:66) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:836) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1839) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.base/java.lang.Thread.run(Thread.java:835) 方法，以返回Startontroller#start()而不是String

我将基于xml的配置更改为基于Java /基于注释的配置

我在ThymeleafView中实现了ApplicationContextAware并将其手动设置为我的StartController

和

什么都不起作用，总是相同的错误
