Question

嗨我有简单的Spring应用程序：

WebConfig.java：

package spittr.web;

@Configuration
@EnableWebMvc
@ComponentScan("spittr.web")
public class WebConfig extends WebMvcConfigurerAdapter {

      @Override
      public void addResourceHandlers(ResourceHandlerRegistry registry) {
        super.addResourceHandlers(registry);
      }

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

registerForm.jsp：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="sf" %>
<%@ page session="false" contentType="text/html; charset=UTF-8" %>
<html>
  <head>
    <title>Spittr</title>
    <link rel="stylesheet" type="text/css" 
          href="<c:url value="/resources/style.css" />" >
  </head>
  <body>
    <h1>registration</h1>

 <sf:form method="POST" commandName="spitter" >

      <sf:errors path="*" element="div" cssClass="errors" />

      <sf:label path="firstName" 
          cssErrorClass="error">name</sf:label>: 
        <sf:input path="firstName" cssErrorClass="error" /><br/>

         ....

      <input type="submit" value="register" />
    </sf:form>
  </body>
</html>

当我在以上注册表格中获取：

  @RequestMapping(value="/register", method=GET)
  public String showRegistrationForm(Model model) {
      model.addAttribute("spitter", new Spitter());
    return "registerForm";
  }

CSS文件没有加载，我得到JSP页面，但没有CSS样式，并且在Tomcat控制台中有错误：

127.0.0.1 - - [22 / Nov / 2016：18：04：48 +0100]“GET /Spittr-0.0.1-SNAPSHOT/resources/style.css HTTP / 1.1”405 1045

问题出在哪里？ CSS文件位于 /Spittr-0.0.1-SNAPSHOT/resources/style.css 路径中，并且我指定了默认资源处理程序，因此为什么JSP页面无法获取此静态文件。

感谢您的任何建议：）

Answer 1

好的，我明白了：

1-从 WebMvcConfigurationSupport

重写 resourceHandlerMapping（）

@Override
@Bean
public HandlerMapping resourceHandlerMapping() {
    AbstractHandlerMapping handlerMapping = (AbstractHandlerMapping) super.resourceHandlerMapping();
    handlerMapping.setOrder(-1);
    return handlerMapping;
}

2 - 从 WebMvcConfigurationSupport / WebMvcConfigurerAdapter 覆盖 addResourceHandlers（）：

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

Spring - 无法获取资源（405错误）
