有没有办法使用JAVA将第三方jar添加到Azure功能。我需要让json-simple jar和jackson-databind jar在运行时可用于该函数。现在,我的代码抛出一个运行时异常(ClassNotFound Exception),因为该函数在运行时无法引用jar,因为它不可用。
我尝试使用maven-shade-plugin。它确实创建了一个包含外部jar的可执行jar,但部署仍然采用原始jar。
请建议。
感谢。

我遇到了同样的问题,我想出了如何安排解决方案。
首先,按照this link的简明指南,从一个全新的Maven项目开始。
假设<project_root_path>
为您要创建项目的文件夹。
生成maven项目后,只需在<project_root_path>/pom.xml
<build><plugins>...</plugins></build>
内的<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<outputDirectory>${project.build.directory}/azure-functions/${functionAppName}</outputDirectory>
<appendAssemblyId>false</appendAssemblyId>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<archive />
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>assembly</goal>
</goals>
</execution>
</executions>
</plugin>
添加 maven-assembly-plugin 插件:
mvn clean compile package
使用命令<project_root_path>/target/<project_name>.jar
编译和打包Azure函数将在路径<dependencies></dependencies>
上生成一个jar,其中包含pom.xml <project_name>
下列出的所有外部库。
注1 :如果您未修改标准pom.xml,则会根据<artifactId>_<version>.jar
生成<appendAssemblyId>false</appendAssemblyId>
。
注意2 :如果您未在上述代码段中使用<project_name>
指令,则<artifactId>_<version>-<descriptorRef>.jar
将为<project_root_path>/target/<project_name>.jar
。请考虑以下说明。
所以,现在您应该拥有完整的<project_root_path>/target/azure-functions/<azure_function_name>/
,但在使用之前,您必须将其复制到<azure_function_name>
下,其中mvn azure-functions:run
是您在创建过程中为您的函数指定的名称记录在above link。
现在您可以使用Azure Maven插件测试它:
mvn azure-functions:deploy
<outputDirectory>${project.build.directory}/azure-functions/${functionAppName}</outputDirectory>
最后,关键点是将使用maven-assembly-plugin生成的jar移动到Azure Maven插件在运行/部署过程中所看到的正确位置。我希望我能找到一种使用标准Maven命令的更自动的方式。
希望这有帮助。

在<configuration>
POM标记中添加<goal>
并将mvn azure-functions:run
标记更改为程序集,它使Maven自动复制Azure功能登台目录中的最终JAR。这允许mvn azure-functions:deploy
和<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.0</version>
<configuration>
<shadedArtifactAttached>false</shadedArtifactAttached>
<outputFile>${project.build.directory}/azure-functions/${functionAppName}/${project.artifactId}-${project.version}.jar</outputFile>
<filters>
<filter>
<artifact>*:*</artifact>
<excludes>
<exclude>META-INF/*.SF</exclude>
<exclude>META-INF/*.DSA</exclude>
<exclude>META-INF/*.RSA</exclude>
</excludes>
</filter>
</filters>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
</execution>
</executions>
</plugin>
命令直接使用包含所有依赖项的正确JAR文件。不再需要手动操作。
上述POM已相应更新。

如果您想使用Maven Shade插件而不是Maven Assembly插件,请将上述XML代码段替换为以下内容:
innerHTML
它将使用之前提到的相同标准Maven命令。

您用于准备Azure Function项目的pom.xml
生成的azure-functions-archetype
的最新版本(有关更多详细信息,请参见this link)似乎已经包含用于复制依赖项的插件。
我的pom.xml
默认情况下包括以下插件,并且它似乎自动将我指定的依赖项复制到${stagingDirectory}/lib
中。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${stagingDirectory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
<includeScope>runtime</includeScope>
<excludeArtifactIds>azure-functions-java-library</excludeArtifactIds>
</configuration>
</execution>
</executions>
</plugin>
