Java 如何使用maven为Spring指定loadTimeWeaver

我有一个奇怪的错误。我在intelliJIDEA IDE中运行了一个基本的spring boot web服务器（在jetty上）

当我运行maven“package”命令，并尝试从命令行运行web服务器时，它会给我一个loadTimeWeaver错误。我不理解这两种运行环境之间的区别，在我看来，它确实应该工作

在IDEA中，我在运行配置中指定以下内容：
主要类别：包装、起动机
VM选项：-javaagent:C:/Users/newb/EXT_LIBS/spring-instrument-4.0.3.RELEASE.jar-noverify

在命令行中，我尝试执行以下操作：
java-javaagent:C:/Users/newb/EXT_LIBS/spring-instrument-4.0.3.RELEASE.jar-noverify-jar target\MySpringServer.war

但我得到了以下错误：

解决此loadTimeWeaver问题的最佳方法是什么？有没有理由认为它可以在我的IDE中工作，但不能在IDE之外工作？我已经尝试强制设置loadTimeWeaver，但这并不是一件小事，而且它在我的IDE中工作这一事实意味着我只需要检查一些非常小的事情

提前谢谢

编辑：
我找到了答案！以下问题对我很有帮助：

基本上，我还需要在命令行上指定-Xbootclasspath/a:C:/Users/newb/EXT_LIBS/spring-instrument-4.0.3.RELEASE.jar。现在它没有给我那些加载时间编织错误！呜

这应该可以解决您的问题

@Bean
public InstrumentationLoadTimeWeaver loadTimeWeaver()  throws Throwable {
    InstrumentationLoadTimeWeaver loadTimeWeaver = new InstrumentationLoadTimeWeaver();
    return loadTimeWeaver;
}

在配置中也可以这样做

发现了一个新的解决方案，该方案只解决了动态设置spring InstrumentationLoadTimeWeaver以支持方面，而无需使用显式java代理启动JVM

<dependency>
    <groupId>de.invesdwin</groupId>
    <artifactId>invesdwin-instrument</artifactId>
    <version>1.0.2</version>
</dependency>

是 啊它非常适合我，并且使LTW配置更容易避免指定jvm--javaagent arg！，它非常适合我，使LTW配置更容易避免指定jvm--javaagent arg。我很好奇，你需要加载时编织做什么？我很好奇，你需要加载时编织做什么？
