找不到运行时未初始化的类

错误信息：

Error: Classes that should be initialized at run time got initialized during image building:

org.slf4j.LoggerFactory was unintentionally initialized at build time. To see why org.slf4j.LoggerFactory got initialized use --trace-class-initialization=org.slf4j.LoggerFactory

遇到这种错误，先找出所有的完整类名，比如这里的是 org.slf4j.LoggerFactory，然后记下。

在 pom.xml 的 plugins 找到下面的插件：

<plugin>
    <groupId>org.graalvm.buildtools</groupId>
    <artifactId>native-maven-plugin</artifactId>
</plugin>

添加配置参数，改成下面这样：

<plugin>
    <groupId>org.graalvm.buildtools</groupId>
    <artifactId>native-maven-plugin</artifactId>
    <!-- Native Build Solutions from: https://www.bilibili.com/opus/965880411977678853 -->
    <configuration>
        <buildArgs>
            --no-fallback
            --initialize-at-build-time=org.slf4j.LoggerFactory
            --initialize-at-build-time=org.slf4j.simple.SimpleLogger
            --initialize-at-build-time=org.slf4j.MDC
            --initialize-at-build-time=ch.qos.logback.classic.Level
            --initialize-at-build-time=ch.qos.logback.classic.Logger
            --initialize-at-build-time=ch.qos.logback.core.util.StatusPrinter
            --initialize-at-build-time=ch.qos.logback.core.status.StatusBase
            --initialize-at-build-time=ch.qos.logback.core.status.InfoStatus
            --initialize-at-build-time=ch.qos.logback.core.spi.AppenderAttachableImpl
            --initialize-at-build-time=ch.qos.logback.core.util.Loader
            --initialize-at-build-time=org.slf4j.impl.StaticLoggerBinder
            --initialize-at-build-time=ch.qos.logback.classic.spi.ThrowableProxy
            --initialize-at-build-time=ch.qos.logback.core.CoreConstants
            --initialize-at-build-time=ch.qos.logback.core.util.StatusPrinter2
            --initialize-at-build-time=org.slf4j.helpers.Reporter
            -H:+ReportExceptionStackTraces
        </buildArgs>
    </configuration>
</plugin>

只需将找不到的类用 --initialize-at-build-time= 提前指出就好了，根据实际情况补全即可，上面已经尽可能完整的给出了。

找不到构造函数

错误信息：

kotlin.reflect.jvm.internal.KotlinReflectionInternalError: Could not compute caller for function: public constructor UserRegisterDTO(username: kotlin.String, password: kotlin.String, email: kotlin.String, emailCode: kotlin.String)

这种情况出现在 Kotlini 编写的 SpringBoot 项目打包后的 Runtime，而 SpringBoot 官方提供了一个 @RegisterReflectionForBinding 注解用于解决这个问题。

使用方法很简单，如下所示：s

@Configuration
@RegisterReflectionForBinding(UserRegisterDTO::class)
class NativeBuildConfig {

}
