Springboot访问静态资源

参考

SpringBoot静态资源的访问

默认的静态资源位置

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;
    }

}

自定义静态资源位置

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

# windows中2种斜杠都可以，Linux中使用右斜杠。统一使用右斜杠。
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：实现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：结尾一定以斜杠结尾，不然不起效果。
    */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
            .addResourceLocations("file:E:\\mozq\\image\\account\\img\\",
                    "classpath:/static/",
                    "file:e:/mozq/");
    }
}

静态资源访问路径匹配

# 指定以.txt结尾的url是访问静态资源。
spring:
  mvc:
    static-path-pattern: /**/*.txt

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