Spring boot 1.5.9，访问 Docker 容器中的资源镜像时出现 404 错误

标签 spring spring-boot docker spring-mvc spring-security

在 Spring Boot 1.5.9 应用程序中，我想使用 Google Chrome 通过 HTTP 访问静态资源。

在 Docker 中，我有 404错误 ，它在嵌入式 tomcat 中运行良好。

配置

这是Dockerfile :

FROM openjdk:8-jre-alpine
VOLUME /tmp

RUN addgroup -S spring --gid 13371 && adduser -S spring -G spring --uid 13371
RUN mkdir -p /srv/upload
RUN chown -R spring:spring /srv/upload

ADD *.jar app.jar
RUN sh -c 'touch /app.jar'

USER spring:spring

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Duser.timezone=UTC","-jar","/app.jar"]

这是我配置静态资源的方式:

public class MyWebMvcConfigurerAdapter extends WebMvcConfigurerAdapter { 
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**")
                .addResourceLocations("file:upload/images/")
                .setCachePeriod(0);
    }
}

结果

这是我从 chrome 访问 URL 时的结果日志 在码头 http://localhost:8080/resources/promotions/37/lg/31723d95-eec3-4ff9-aa42-e3477559e9df.png

调查

我已经在本地复制了生产环境，并且使用了相同的绝对路径file:/srv/upload/images在开发中，我可以确认状态代码在 docker 和没有它的情况下是不同的:
  • 在嵌入式 tomcat 中:200
  • 在 docker :404

    • 问题与路径不同无关，而仅与 docker 有关。

    题
  • 有没有我忘记的步骤？

    • 任何提示将不胜感激。

    最佳答案

    我没有足够的声望点来发表评论，所以我写下我的评论作为答案:(

    我在 docker 和资源方面遇到了类似的问题，所以我想帮助你。

    你能提供带有TRACE的日志吗？等级？
    这个级别帮助我们了解内部发生了什么PathResourceResolver并根据此 implementation大多数情况下使用跟踪。

    就我而言，它很有用并帮助了我。

    根据 this

    You can enable a “trace” mode by starting your application with a --trace flag (or trace=true in your application.properties)
