SpringBoot靜態資源的訪問

默認的靜態資源位置

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

@ConfigurationProperties(prefix = "spring.resources", ignoreUnknownFields = false)
public class ResourceProperties {

    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = { 
        "classpath:/META-INF/resources/",                              
        "classpath:/resources/", 
        "classpath:/static/", 
        "classpath:/public/" };

    public void setStaticLocations(String[] staticLocations) {
        this.staticLocations = appendSlashIfNecessary(staticLocations);
    }

    private String[] appendSlashIfNecessary(String[] staticLocations) {
        String[] normalized = new String[staticLocations.length];
        for (int i = 0; i < staticLocations.length; i++) {
            String location = staticLocations[i];
            normalized[i] = location.endsWith("/") ? location : location + "/";
        }
        return normalized;
    }

}

自定義靜態資源位置

方法一：配置文件 spring.resources.static-locations

# windows中2種斜槓均可以，Linux中使用右斜槓。統一使用右斜槓。
spring:
  resources:
    #static-locations: classpath:/mybatis/, file:E:\image\account\img
    static-locations: classpath:/mybatis/, file:E:${server.servlet.context-path}/image/account/img

方法二：實現WebMvcConfigurer接口

package com.mozq.boot.upload01.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    /*
        注意：結尾必定以斜槓結尾，否則不起效果。
    */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
            .addResourceLocations("file:E:\\mozq\\image\\account\\img\\",
                    "classpath:/static/",
                    "file:e:/mozq/");
    }
}

靜態資源訪問路徑匹配

# 指定以.txt結尾的url是訪問靜態資源。
spring:
  mvc:
    static-path-pattern: /**/*.txt

@ConfigurationProperties(prefix = "spring.mvc")
public class WebMvcProperties {
    private String staticPathPattern = "/**";
}
