JAR中的Spring Boot + Elastic Beanstalk .ebextensions

Question

我有一个非常标准的Spring Boot应用程序(application.properties属性文件位于标准/src/main/resources文件夹中),我将其作为"胖JAR"部署在AWS Elastic Beanstalk上.它工作得很好,但是服务器上的图像上传存在问题.经过一些调查后,似乎需要调整NGINX配置(增加到client_max_body_size可以接受上传的内容10MB),因此我添加了一个带有以下内容的文件.ebextensions夹/src/main/resources(取自此答案): -

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我的构建时,它不会.ebextensions在根文件夹中创建,我想知道什么是最佳解决方案.我的pom.xml文件很小,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<resources> ...向我插入XML pom.xml然后启动服务器时,它崩溃了以下内容: -

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修复了这个问题,所以不幸的是这不起作用.

上一节中描述的问题似乎是新<resources>指向.ebextentions覆盖了以下<resources>定义的块: -

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

为了使一切正常,我将其复制并附加到末尾,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>

谢谢大家的帮助!

这是一个pom片段,它将使它适用于JAR:

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

它的工作方式与将.ebextensions移动到.war文件 中的方式相同

实际上我把样本上传到了这个仓库.做一个mvn package

Lorena Salamanca Spring Boot + Elastic Beanstalk .ebextensions在JAR中提出的解决方案不适用于我...：\

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以下代码段：

<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>

此插件使用ant解压缩由春季启动生成的最终jar，将.ebextensions复制到根目录中，然后再次使用相同的名称压缩（jar）。经过测试并在生产中工作：）
