java - STS v3.5.0.RELEASE x64 不会热交换 VM 类

Question

我正在使用 Windows 8.1 x64 瑞典语。我试图关注这个https://www.youtube.com/watch?v=GTrNkhVnJBU有关如何使 STS 进行热插拔的指南。我将 Eclipse 设置为自动构建，并且检查了类文件实际上是否已在目标目录中替换。我添加了 javaagent 参数。我还测试了使用我的 VM 参数从命令行（一个简单的 hello world）启动它，尽管我的用户名包含空格，但它会启动。我试图将 springloaded.jar 移动到不包含空格的文件夹中。仍然没有热插拔。为了测试它，我重建了我的命令行 hello world 或在 STS 中我改变了一个字符串并保存了文件。该类自动构建，但网页仍打印旧消息。STS 安装目录为 C:\dev\Apps\STS。.m2 存储库的路径中有空格。我试过 jdk 1.7.0_25、jdk 1.7.0_55 和 springloaded-1.1.5.RELEASE.jar、springloaded-1.2.0.RELEASE.jar

Answer 1

当您启动附加了弹簧加载代理的应用程序时，您在 STS 的控制台视图中看到了什么？您是否注意到有关 springloaded-1.2.0.RELEASE.jar 未找到或无法打开的任何消息？您可以在此处粘贴您的启动配置 VM 参数吗？

修改代码并保存后，看起来成功的热交换应该会在控制台视图中产生如下所示的消息： [Loader@5cfab5b1] swsmmaRequestMappingHandlerMapping : Mapped "{[/greeting],methods=[],params=[ ],headers=[],consumes=[],produces=[],custom=[]}" 到公共 hello.Greeting hello.GreetingController.greeting(java.lang.String)

Lauch configuration arguments as requested:
-Dspring.liveBeansView.mbeanDomain
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=38900
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

Program arguments:
-javaagent:C:/Users/Anna\ Ohlsson/.m2/repository/org/springframework/springloaded/1.2.0.RELEASE/springloaded-1.2.0.RELEASE.jar -noverify

This is what the boot up messages look like. Someone requested to see them.
