springboot项目访问静态资源的配置代码实例

这篇文章主要介绍了springboot项目访问静态资源的配置代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

这里只是简单记录当上传图片不是放在tomcat其他服务器中时，只是放在磁盘中便可以这样配置，在项目启动后可以访问到磁盘中的资源。

@Configuration
public class SystemConfigurer implements WebMvcConfigurer {

  @Value("${jeewx.path.upload}")
  private String upLoadPath; //配置的文件的存储位置如 “E://image”
  @Value("${spring.resource.static-locations}")
  private String staticLocations; //其他静态资源位置，如js,css文件

  /**默认拦截器排除资源*/
  private List<String> EXCLUDE_PATHS= Arrays.asList("/plug-in/**","/content/**","/upload/**","/system/*.do","/error");
  @Autowired
  private LoginInterceptor loginInterceptor;
  @Autowired
  private AccessSignInterceptor accessSignInterceptor;

  @Value("${jeewx.interceptor.is-open}")
  private boolean isOpen;
  @Value("${jeewx.interceptor.excludeUrls.login-interceptor}")
  private String loginInterceptorExcludeUrls;
  @Value("${jeewx.interceptor.excludeUrls.access-sign-interceptor}")
  private String accessSignInterceptorExcludeUrls;

   /**
   * 静态资源的配置 - 使得可以从磁盘中读取 Html、图片、视频、音频等
   */
  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/**")
        .addResourceLocations("file:" + upLoadPath + "//")
        .addResourceLocations(staticLocations.split(","));
  }
/** * 登录验证码 */ @Bean @SuppressWarnings({ "rawtypes","unchecked" }) public ServletRegistrationBean randCodeImageServlet() { ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new RandCodeImageServlet(),"/randCodeImage"); return servletRegistrationBean; } /** * 拦截器（登录 + 签名） */ public void addInterceptors(InterceptorRegistry registry) { if(isOpen) { log.info("loginInterceptorExcludeUrls: "+loginInterceptorExcludeUrls); log.info("accessSignInterceptorExcludeUrls: "+accessSignInterceptorExcludeUrls); registry.addInterceptor(loginInterceptor).addPathPatterns("/**/back/**/*").excludePathPatterns(EXCLUDE_PATHS).excludePathPatterns(loginInterceptorExcludeUrls.split(",")); registry.addInterceptor(accessSignInterceptor).addPathPatterns("/**").excludePathPatterns("/**/back/**").excludePathPatterns(EXCLUDE_PATHS).excludePathPatterns(accessSignInterceptorExcludeUrls.split(",")); } } /** * 默认跳转登录页面 */ @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/").setViewName("redirect:/system/login.do"); registry.setOrder(Ordered.HIGHEST_PRECEDENCE); } }
