静态资源配置

Spring Boot 默认将 /** 所有访问映射到以下目录：

classpath:/staticclasspath:/publicclasspath:/resourcesclasspath:/META-INF/resources

如果需要自定义映射目录，可以继承WebMvcConfigurerAdapter或WebMvcConfigurationSupport，以后者为例，如下：

@Configurationpublic class WebConfig extends WebMvcConfigurationSupport {        @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {        //将所有/static/** 访问都映射到classpath:/static/ 目录下        registry.addResourceHandler("/js/**").addResourceLocations("classpath:/static/js/");        registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/static/resources/");        registry.addResourceHandler("/images/**").addResourceLocations("classpath:/static/images/");        registry.addResourceHandler("/css/**").addResourceLocations("classpath:/static/css/");        registry.addResourceHandler("/font/**").addResourceLocations("classpath:/static/font/");        registry.addResourceHandler("/themes/**").addResourceLocations("classpath:/static/themes/");    }}

如果使用了拦截器HandlerInterceptor，好像覆盖addResourceHandlers方法，似乎excludePathPatterns并没有生效，不覆盖的话前台会报404。

拦截器配置 

同样在WebConfig中配置，如下：

package com.hundsun.ta.aop.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;import com.hundsun.ta.interceptor.SecurityInteceptor;@Configurationpublic class WebConfig extends WebMvcConfigurationSupport {    // 需要注意的是HandlerInteceptor必须通过@Bean配置，直接添加@new SecurityInteceptor()会导致依赖类未注入    @Bean    SecurityInteceptor securityInteceptor() {        return new SecurityInteceptor();    }    @Override    protected void addInterceptors(InterceptorRegistry registry) {        registry.addInterceptor(securityInteceptor()).excludePathPatterns("/css/**", "/js/**", "/font/**", "/images/**", "/resources/**", "/themes/**");        super.addInterceptors(registry);    }}
