spring-boot - JAR 中的 Spring Boot + Elastic Beanstalk .ebextensions

Question

我有一个非常标准的 Spring Boot 应用程序(带有位于标准 application.properties 文件夹中的 /src/main/resources 属性文件)，我将其作为“胖 JAR”部署在 AWS Elastic Beanstalk 上。它工作得很好，但在服务器上上传图像存在问题。经过一些调查，似乎需要调整 NGINX 配置(将 client_max_body_size 增加到某些内容，以便它可以接受上传到 10MB )，因此我添加了一个 .ebextensions文件夹下 /src/main/resources具有以下内容的文件(取自 this answer ):-

files:
    "/etc/nginx/conf.d/proxy.conf":
        mode: "000755"
        owner: root
        group: root
        content: |
           client_max_body_size 20M;

但是，当我运行 mvn 时在我的构建中它不会创建 .ebextensions在根文件夹中，我想知道什么是最好的解决方案。我的 pom.xml文件非常小，目前包含以下内容:

    ...

    <packaging>jar</packaging>

    ....

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>

            <dependencies>
                <dependency>
                    <groupId>org.springframework</groupId>
                    <artifactId>springloaded</artifactId>
                    <version>1.2.6.RELEASE</version>
                </dependency>
            </dependencies>

        </plugin>

提前致谢!

@Lorena 当我插入时 <resources> ... XML 进入我的 pom.xml然后启动它崩溃的服务器如下: -

2017-03-20 21:40:29.504  WARN 10784 --- [           main] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'emailApiSpringBootMail': Unsatisfied dependency expressed through field 'javaMailSender'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.mail.javamail.JavaMailSender' available: expected at least 1 bean which qualifies as autowire candidate.

Description:

Field javaMailSender in com.myapp.server.api.impl.EmailApiSpringBootMail required a bean of type 'org.springframework.mail.javamail.JavaMailSender' that could not be found.
    - Bean method 'mailSender' not loaded because AnyNestedCondition 0 matched 2 did not; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.JndiNameProperty @ConditionalOnProperty (spring.mail.jndi-name) did not find property 'jndi-name'; NestedCondition on MailSenderAutoConfiguration.MailSenderCondition.HostProperty @ConditionalOnProperty (spring.mail.host) did not find property 'host'

再次删除 XML 解决了这个问题，所以不幸的是这不起作用。

上一节描述的问题似乎是新的 <resources>指向 .ebextentions覆盖了 <resources>块定义在: -

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.4.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

为了让一切正常，我复制了它并附加到末尾，如下所示:-

    <resources>

        <resource>
            <directory>src/main/resources/ebextensions</directory>
            <targetPath>.ebextensions</targetPath>
            <filtering>true</filtering>
        </resource>

        <!-- Followed is copied from `spring-boot-starter-parent.pom` -->

        <resource>
            <directory>${basedir}/src/main/resources</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/application*.yml</include>
                <include>**/application*.properties</include>
            </includes>
        </resource>
        <resource>
            <directory>${basedir}/src/main/resources</directory>
            <excludes>
                <exclude>**/application*.yml</exclude>
                <exclude>**/application*.properties</exclude>
            </excludes>
        </resource>

    </resources>

感谢大家的帮助!

Lorena Salamanca 提出的解决方案 Spring Boot + Elastic Beanstalk .ebextensions in JAR对我不起作用...:\

我的解决方案适用于 Spring 1.5.3.RELEASE

在项目的根目录中添加 .ebextensions 并在插件部分的末尾添加此代码段:

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-antrun-plugin</artifactId>
            <version>1.6</version>
            <executions>
                <execution>
                    <id>prepare</id>
                    <phase>package</phase>
                    <configuration>
                        <tasks>
                            <unzip src="${project.build.directory}/${project.build.finalName}.jar" dest="${project.build.directory}/${project.build.finalName}" />
                            <copy todir="${project.build.directory}/${project.build.finalName}/" overwrite="false">
                                <fileset dir="./" includes=".ebextensions/**"/>
                            </copy>
                            <!-- <jar jarfile="${project.build.directory}/${project.build.finalName}.jar" basedir="${project.build.directory}/${project.build.finalName}"/>-->
                            <zip compress="false" destfile="${project.build.directory}/${project.build.finalName}.jar" basedir="${project.build.directory}/${project.build.finalName}"/>
                        </tasks>
                    </configuration>
                    <goals>
                        <goal>run</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

本插件使用ant解压spring boot生成的最终jar，复制根目录下的.ebextensions，再次用同名压缩(jar)。经过测试并在生产中工作:)
