Question

我想在项目资源中的静态目录中提供静态内容，但是出现错误：org.springframework.web.HttpRequestMethodNotSupportedException：请求方法'GET'不支持。

我添加了配置的Spring Security以忽略以“ / static /”开头的请求。我已将资源处理程序添加到WebMvcConfig中以在各个不同的位置查找静态内容，我尝试完全删除该资源处理程序。

我尝试将allowAll（）添加到“ / static /”路径。

我已经用错误信息及其各种组合搜索了Google，以查找解决方案。这是我提出Spring Security和WebMvcConfigs的地方。只是这些并不能解决我的问题。

最后，我尝试将静态文件放置在不同的位置。目录结构如下：

\resources\static\hello.css
\resources\static\css\hello.css
\resources\templates\home.html
\resources\templates\error.html

Thymeleaf正常工作，可以从模板目录中获取模板。

WebMvcConfig：

// Config Thymeleaf
private static final String VIEWS = "classpath:templates/";

@Bean
public ViewResolver viewResolver() {
    ThymeleafViewResolver resolver = new ThymeleafViewResolver();
    resolver.setTemplateEngine(templateEngine());
    resolver.setCharacterEncoding("UTF-8");
    return resolver;
}

private ISpringTemplateEngine templateEngine() {
    SpringTemplateEngine engine = new SpringTemplateEngine();
    engine.setTemplateResolver(templateResolver());
    return engine;
}

private ITemplateResolver templateResolver() {
    SpringResourceTemplateResolver resolver = new SpringResourceTemplateResolver();
    resolver.setApplicationContext(applicationContext);
    resolver.setPrefix(VIEWS);
    resolver.setSuffix(".html");
    resolver.setTemplateMode(TemplateMode.HTML);
    return resolver;
}

// Enable static resources
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry
            .addResourceHandler("/static/**")
            .addResourceLocations("/resources/static/", "classpath:static/", "/static/", "classpath:resources/static");
}

Spring Security配置：

@Override
public void configure(WebSecurity web) throws Exception {
    web
        .ignoring()
        .antMatchers("/static/**");
}

我希望看到我的css文件，但是我看到由异常处理程序生成的错误页面，并显示消息“不支持请求方法'GET'”

这是从我请求css文件开始的调试跟踪：

Answer 1

经过数小时的调试，我发现未提供静态内容的原因！这是因为具有映射的控制器没有路径：

@PostMapping()

在将路径添加到映射后，上面的配置可以正常工作。很奇怪，它弄乱了静态文件的投放！

非常感谢@Ganesh在Spring Boot not serving static content中的提示

感谢@Avaruuskadetti，您节省了我的时间

调试：软件包org.springframework.web.servlet >>>> HandlerExecutionChain

protected HandlerExecutionChain getHandler(HttpServletRequest request) throws Exception {
    if (this.handlerMappings != null) {
        Iterator var2 = this.handlerMappings.iterator();

        while(var2.hasNext()) {
            HandlerMapping hm = (HandlerMapping)var2.next();
            if (this.logger.isTraceEnabled()) {
                this.logger.trace("Testing handler map [" + hm + "] in DispatcherServlet with name '" + this.getServletName() + "'");
            }

            HandlerExecutionChain handler = hm.getHandler(request);
            if (handler != null) {
                return handler;
            }
        }
    }

    return null;
}

提供静态内容会导致请求方法“ GET”不受支持
