Spring 引导 + JAR 中的 Elastic Beanstalk .ebextensions

Spring Boot + Elastic Beanstalk .ebextensions in JAR

我有一个非常标准的 Spring 引导应用程序(在标准 /src/main/resources 文件夹中有一个 application.properties 属性文件),我将其作为 "fat JAR"。它工作得很好,但在服务器上上传图像时存在问题。经过一些调查后,似乎需要调整 NGINX 配置(将 client_max_body_size 增加到某种程度,以便它可以接受高达 10MB 的上传),因此我在 [=] 下添加了一个 .ebextensions 文件夹17=] 和一个包含以下内容的文件(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 在我的构建中它不会在根文件夹中创建 .ebextensions,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 当我将 <resources> ... XML 插入我的 pom.xml 然后启动服务器时,它崩溃并显示以下内容:-

再次删除 XML 可以解决问题,但不幸的是,这将不起作用。

上一节中描述的问题似乎是指向 .ebextentions 的新 <resources> 覆盖了定义在 -

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

为了让一切正常运行,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>

感谢大家的帮助!

这是一个可以用于 JAR 的 pom 片段:

<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 文件中的根目录相同

其实我把样本上传到这个repo。只需做一个 mvn package

您收到的错误消息是针对未找到 javaMailSender 属性。

您在 pom.xml 中提到的资源路径会覆盖默认的资源根路径。

因此 JavaMailSender 正在此新资源路径下寻找 jndi 配置或邮件属性,但找不到它。因此出现错误。

spring.mail.jndi-name=mail/testmail

spring.mail.host=testserver.com
spring.mail.port=25
spring.mail.username=test
spring.mail.password=test123
spring.mail.protocol=smtp
spring.mail.defaultEncoding=UTF-8
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.auth.mechanisms=NTLM
spring.mail.properties.mail.smtp.auth.ntlm.domain=DOMAIN
spring.mail.properties.mail.debug=true

实际上是 spring-boot jar 相关的问题。由于您使用的是 1.2.6 版本的 spring-boot,它有一些错误,例如 javamailsender 问题。您需要将 spring 引导版本升级到 1.3.0.release 以上。

在此 ticket#3478 中,已修复 spring-boot 的邮件发送器问题。 所以你可以升级到最新版本或其他超过 1.3.0 版本的版本。

<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter</artifactId>
    <version>1.3.5.RELEASE</version>
</dependency>

希望这能解决您的问题。

Lorena Salamanca 提出的解决方案对我不起作用...:\

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,再次同名zip(jar)。经过测试并投入生产:)

我相信在这种情况下使用的是独立的 JAR,使用 Procfile-based configuration 然后将 JAR 和 .ebextensions 捆绑到一个 zip 文件中会更容易。

首先在项目的根目录下创建一个名为Procfile的文件,内容如下:

web: java -jar sample_app-1.0.0.jar

然后创建一个 zip 文件,其中包含 JAR 和 Procfile 文件以及 .ebextensions 目录:

sample_app.zip
|
|_.ebextensions
|   |_ nginx
|      |_ conf.d
|         |_ proxy.conf
|
|_ sample_app-1.0.0.jar
|_ Procfile
