靜態資源配置

Spring Boot 預設將 /** 所有訪問對映到以下目錄：

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

如果需要自定義對映目錄，可以繼承WebMvcConfigurerAdapter或WebMvcConfigurationSupport，以後者為例，如下：

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {
    
    @Override
    
 
public void addResourceHandlers(ResourceHandlerRegistry registry) {
        //將所有/static/** 訪問都對映到classpath:/static/ 目錄下
        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/");
    }

}
 

如果使用了攔截器HandlerInterceptor，好像覆蓋addResourceHandlers方法，似乎excludePathPatterns並沒有生效，不覆蓋的話前臺會報404。

攔截器配置 

同樣在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;

@Configuration
public class WebConfig extends WebMvcConfigurationSupport {
    // 需要注意的是HandlerInteceptor必須通過@Bean配置，直接新增@new SecurityInteceptor()會導致依賴類未注入
    @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);
    }
}
