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

Question

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：

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"]

结果

这是我从 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

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

预期的

这是我在访问时所期望的（在开发环境中） http://localhost:8080/resources/promotions/39/lg/843291ef-2309-4809-9f37-38257e087a97.jpeg

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级别的日志吗？这个级别帮助我们查看内部发生了什么，PathResourceResolver并且根据此实现跟踪在大多数情况下使用。

就我而言，它很有用并帮助了我。

根据这个

您可以通过使用 --trace 标志（或 application.properties 中的 trace=true）启动应用程序来启用“跟踪”模式
