Spring Boot 1.5.9，访问Docker容器中的资源映像时出现404错误

本文介绍了Spring Boot 1.5.9，访问Docker容器中的资源映像时出现404错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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。

In a Spring Boot 1.5.9 application I want to access static resources through HTTP using Google Chrome.

在Docker中，我有 404 错误，它在嵌入式tomcat中可以正常工作。

In Docker I have 404 error, it worked fine in embedded tomcat.

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：

This is how I configure the static resources:

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



结果



这是当我从docker中的Chrome 访问URL时的结果日志。 http：// localhost：8080 / resources / promotions / 37 / lg / 31723d95- eec3-4ff9-aa42-e3477559e9df.png

Result

This is the result log when I access the URL from chrome in docker 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中和没有docker时是否不同：

Investigation

I have replicated the production environment locally and I used the same absolute path file:/srv/upload/images in development, I can confirm that status code are different within docker and without it:


  • 在嵌入式tomcat中： 200

  • 在docker中：404

问题与路径不同无关，但是

The problem is not related to the path being different but only because of docker.


  • 有没有我忘记的步骤？ ？

任何提示将不胜感激。

我在码头工人nd资源，所以我想为您提供帮助。

I had a similar issue with docker and resources, so I would like to help you.

您能提供 TRACE 级的日志吗？
此级别可以帮助我们查看 PathResourceResolver 内部的情况，并根据此跟踪用于在大多数情况下。

Could you provide logs with TRACE level? This level helps us to see what is going on inside PathResourceResolver and according to this implementation trace is used in most cases.

对我来说，它很有用并对我有所帮助。

In my case, it was useful and helped me.
