spring boot 1.4 jsp页面未计算Forward InternalViewResolver

因为我希望所有jsp都有一个新的路径(我知道我们也可以在controller中这样做),我担心会保留相同的servlet来服务angular frontend和jsp。 因为jhipster生成了许多参数化的类(HttpSecurity),所以我认为创建一个新的servlet(没有任何自定义参数)可能更简单,可以避免问题。

DispatcherServlet.render()
--> resolveViewName() qui retourne une JstlView
--> JstlView.render()
--> renderMergedOutputModel()
dispatcherPath = prepareForRendering(request, response);   //  dispatcherPath = /mesPagesJsps/log4jAdmin.jsp
RequestDispatcher rd = getRequestDispatcher() // rd.path=/mesPagesJsps/log4jAdmin.jsp   and   rd.servletChain=another DispatcherServlet !!! why ??? named dispatcherServlet, which is not my jsp servlet
--> rd.forward()
--> forwardImpl()
--> response.resetBuffer()
newServletPath = newRequestUri = /mesPagesJsps/log4jAdmin.jsp
pathMatch.servletChain still contains wrond servlet : dispatcherServlet instead of jspServlet
--> servletContext.getDeployment().getServletDispatcher().dispatchToPath(requestImpl.getExchange(), pathMatch, DispatcherType.FORWARD);
--> servletInitialDispatcher.dispatchToPath()
servletRequestContext.servletChain correspond to my servletJSP
--> dispatchRequest( pathInfo = /mesPagesJsps/log4jAdmin.jsp, dispatcherType=FORWARD, servletChain is not my jsp servletJSP but dispatcherServlet )
Exchange is : HttpServerExchange{ GET /mesPagesJsps/log4jAdmin.jsp request {Accept=[text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8], Accept-Language=[fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3], Cache-Control=[max-age=0], Accept-Encoding=[gzip, deflate], User-Agent=[Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0], Connection=[keep-alive], Cookie=[CSRF-TOKEN=f6843de6-766d-4259-8a84-242c020420bc; JSESSIONID=VrVa7HNkUmzv_JM_cAhwyrfGWGCcrjZSltoQh2EJ], Upgrade-Insecure-Requests=[1], Host=[localhost:8080]} response {X-Application-Context=[testify_jhi:swagger,dev:8080], Content-Language=[fr-]}}
--> servletInitialHandler.dispatchRequest()
setCurrentServlet( WITH SERVLET dispatcherServlet and NOT servletJSP )
--> next.handleRequest(exchange) : next is here a SessionRestoringHandler
--> next.handleRequest(exchange) : next is here PredicateHandler. This called because a sessionId has been found ...
--> predicate.resolve() with a predicate of type REQUEST (I think this bad) --> which return falseHandler
--> next.handleRequest() --> with again a predicate of type REQUEST --> which return falseHandler
--> next.handleRequest() --> with a ServletDispatchingHandler whose ServletChain is the wrong servlet : dispatcherServlet instead of servletJSP
the dispatcher type is still FORWARD here but its to late because I thing the wrong servlet process the request

因为我希望所有jsp都有一个新的路径(我知道我们也可以在controller中这样做),我担心会保留相同的servlet来服务angular frontend和jsp。 因为jhipster生成了许多参数化的类(HttpSecurity),所以我认为创建一个新的servlet(没有任何自定义参数)可能更简单,可以避免问题。

例如,有HttpSecurity,这是:

public void customize(ConfigurableEmbeddedServletContainer container) {
    MimeMappings mappings = new MimeMappings(MimeMappings.DEFAULT);
    // IE issue, see https://github.com/jhipster/generator-jhipster/pull/711
    mappings.add("html", "text/html;charset=utf-8");
    // CloudFoundry issue, see https://github.com/cloudfoundry/gorouter/issues/64
    mappings.add("json", "text/html;charset=utf-8");
    //mappings.add("jsp", "text/html;charset=utf-8"); // si je fais ça, en combinaisais avec le addResourcesHandler(), alors la page jsp est affichée dans le navigateur
    container.setMimeMappings(mappings);
    // When running in an IDE or with ./mvnw spring-boot:run, set location of the static web assets.
    setLocationForStaticAssets(container);
}

我最终发现并解决了这个问题(解决方案如下),它似乎与一些undertow元素有联系,defaut没有配置这些元素来初始化japser。JasperInitializer从未初始化。 如果有人想向我解释,欢迎:)

必须在配置类中添加此代码。

@Bean
public TomcatContextCustomizer tomcatContextCustomizer() {
    return new TomcatContextCustomizer() {
        @Override
        public void customize(Context context) {
            context.addServletContainerInitializer(new JasperInitializer(), null);
        }
    };
}

@Bean
public TomcatEmbeddedServletContainerFactory tomcatContainerFactory() {
     TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
     factory.setTomcatContextCustomizers(Arrays.asList(new TomcatContextCustomizer[] { tomcatContextCustomizer() }));
     return factory;
}

另一个问题:我的spring boot应用程序中没有xml文件,只有一个: 是否可以用web-INF/servletJSP servlet替换我构建的servlet web应用程序上下文定义。xml按java/注释定义?
