classpath:/META-INF/resources
classpath:/resources
classpath:/static
classpath:/public

3.配置檔案

#預設值為 /**
spring.mvc.static-path-pattern=
#預設值為 classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
spring.resources.static-locations=這裡設定要指向的路徑，多個使用英文逗號隔開

4.自定義靜態資源對映

@Configuration
 

public class MyWebMvcConfigurerAdapter extends WebMvcConfigurerAdapter {
    /**
     * 配置靜態訪問資源
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/my/**").addResourceLocations("classpath:/my/");
        super
 
.addResourceHandlers(registry);
    }
}

4.1訪問外部目錄

@Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/my/**").addResourceLocations("file:E:/my/");
        super.addResourceHandlers(registry);
    }

4.2頁面跳轉

/**
     * 以前要訪問一個頁面需要先建立個Controller控制類，再寫方法跳轉到頁面
     * 在這裡配置後就不需要那麼麻煩了，直接訪問http://localhost:8080/toLogin就跳轉到login.jsp頁面了
     * @param
 
 registry
     */
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/toLogin").setViewName("login");
        super.addViewControllers(registry);
    }

5.攔截器

public class MyInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {
        System.out.println("開始攔截--------------------");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {
        System.out.println("攔截中----------------------");
    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {
        System.out.println("攔截完成----------------------");
    }
}

5.1註冊攔截器

/**
* 攔截器
* @param registry
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
    // addPathPatterns 用於新增攔截規則
    // excludePathPatterns 使用者排除攔截
    registry.addInterceptor(new MyInterceptor()).addPathPatterns("/**").excludePathPatterns("/toLogin","/login");
    super.addInterceptors(registry);
}
