我一直收到
意外的404响应上传类文件

这是我的泊坞文件：

FROM java:8
WORKDIR /first
ADD ./build/libs/first.jar /first/first.jar
EXPOSE 8080
RUN bash -c 'touch /first/first.jar'
ENTRYPOINT ["java","-Dspring.data.mongodb.uri=mongodb://mongodb/micros", "-Djava.security.egd", "-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005","-jar", "first.jar"]

这是我的配置和配置

This is my configuration and the configuration

推荐答案

从Spring Boot 1.5.0开始，devtools默认值被更改为从胖罐中排除devtools。

As of Spring Boot 1.5.0, devtools defaults were changed to exclude the devtools from fat jars.

如果你想要包含它们，你必须将 excludeDevtools 标志设置为false。

If you want to include them, you have to set the excludeDevtools flag to false.

但是，devtools文档没有解释如何做到这一点。必要的文档实际上在spring-boot-gradle-plugin文档中。

However, the devtools documentation doesn't explain how to do this. The necessary documentation is actually in the spring-boot-gradle-plugin documentation.

为此，您可以将这段代码放在build.gradle文件中： / p>

To do it, you can put this snippet of code in your build.gradle file:

bootRepackage {
    excludeDevtools = false
}

不幸的是，这起初是错误的，并且从Spring Boot 1.5.0开始没有效果。解决方法是这样做：

Unfortunately, this was buggy at first and had no effect as of Spring Boot 1.5.0. The workaround was to do this instead:

springBoot {
    excludeDevtools = false
}

但是，我已经验证了 bootRepackage 方法适用于Spring启动1.5.8。

However, I have verified that the bootRepackage approach works for Spring Boot 1.5.8 .
