java - GraalVM 不适用于数据库连接

转载作者：行者123 更新时间：2023-12-05 02:26:55

我正在尝试使用 Graalvm 构建 native 图像，但每次我尝试使用 mvn gluonfx:build 构建它时都会出现错误，项目中有数据库连接，例如:H2 DB。

正常运行即可
没有任何数据库连接，原生镜像构建成功

这是pom文件的代码

最佳答案

您有此链接错误:

[Tue Aug 30 12:24:03 EEST 2022][INFO] [SUB] Undefined symbols for architecture arm64:
[Tue Aug 30 12:24:03 EEST 2022][INFO] [SUB]   "_JNI_OnLoad_jaas", referenced from:
[Tue Aug 30 12:24:03 EEST 2022][INFO] [SUB]       ___svm_vm_target_staticlibraries in com.example.demo1.main.driver.o

如果你这样做:

$ nm target/gluonfx/aarch64-darwin/gvm/tmp/SVM-166XXXXX/com.example.demo1.main.driver.o | grep jaas
                 U _JNI_OnLoad_jaas

这意味着您的 native 图像对象中确实存在未解析的符号(作为 gluonfx:compile 的结果)，应该在链接时修复(使用 gluonfx:link).

您可以在日志中看到链接命令，它应该类似于:

gcc /HelloFX/target/gluonfx/aarch64-darwin/gvm/HelloFX/AppDelegate.o /HelloFX/target/gluonfx/aarch64-darwin/gvm/HelloFX/launcher.o \
/HelloFX/target/gluonfx/aarch64-darwin/gvm/tmp/SVM-1661853087924/hellofx.hellofx.o \

-Wl,-force_load,~/.gluon/substrate/javafxStaticSdk/19-ea+8/darwin-aarch64/sdk/lib/libglass.a ... \
-o /HelloFX/target/gluonfx/aarch64-darwin/HelloFX -L~/.gluon/substrate/javafxStaticSdk/19-ea+8/darwin-aarch64/sdk/lib \
-L/~/.gluon/substrate/graalvm/graalvm-svm-java17-darwin-m1-gluon-22.1.0.1-Final/Contents/Home/lib/svm/clibraries/darwin-aarch64 \ 
-L/~/.gluon/substrate/graalvm/graalvm-svm-java17-darwin-m1-gluon-22.1.0.1-Final/Contents/Home/lib/static/darwin-aarch64

注意添加的库:libjava.a、libnio.a、libnet.a、...

这些来自 ~/.gluon/substrate/graalvm/graalvm-svm-java17-darwin-m1-gluon-22.1.0.1-Final/Contents/Home/lib/static/darwin-aarch64.

但是，libjaas.a 库未被链接，这解释了上述错误。

好消息是缺少的库在该路径中与其他库一起可用，因此您可以轻松地将其包含在带有 linkerArgs 的链接命令中。 :

           <plugin>
                <groupId>com.gluonhq</groupId>
                <artifactId>gluonfx-maven-plugin</artifactId>
                <version>${gluonfx.maven.plugin.version}</version>
                <configuration>
                     <target>${gluonfx.target}</target>
                     <mainClass>${main.class}</mainClass>
                     <linkerArgs>
                         <arg>-ljaas</arg>
                     </linkerArgs>
                </configuration>
            </plugin>

现在再次运行 mvn gluonfx:link，链接错误应该消失了。

其他一些提示:

使用推荐的 Gluon 版本的 GraalVM 22.1.0.1-Final(参见 docs)
运行 mvn gluonfx:runagent(如果您还没有运行的话)，在构建 native 镜像之前，发现反射在您的项目中的所有用途。
不要使用--allow-incomplete-classpath，最好提前修复错误。
Media 对 GluonFX 插件的支持非常有限(基于您的依赖项)(参见 docs。
