java - JHipster Eclipse 项目在“main”中内存不足

Question

我正在建立一个不涉及任何花里胡哨的基线 JHipster 项目（没有集群等）。我正在使用我的标准启用节点的（当然）命令行遵循确切的教程步骤，然后将项目作为 Maven 项目导入 Eclipse。根据对项目的审查，一切看起来都应该可以正常工作，除非我尝试在服务器上运行它或使用 mvn 命令行构建它......

错误信息

INFO: Starting Servlet Engine: Apache Tomcat/7.0.12
Exception in thread "main" 
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "main"

POM/Maven

据我所知，这可能是一个 POM 依赖错误，但如果是这样，那么我有一段时间要弄清楚是哪个。我的项目直接配置为使用 JRE 1.7。我的POM在下面。另一个想法是它与 Hipster 的原始 NPM 安装直接相关（在 POM 之后）：

查看 NPM 在初始 JHipster 生成时响应的内容，我实际上也在这些日志中看到了错误，如下所述。有人有这方面的背景吗？

2400 verbose etag pad-stdio from cache
2401 error Error: No compatible version found: findup-sync@'^0.1.2'
2401 error Valid install targets:
2401 error ["0.1.0","0.1.1","0.1.2","0.1.3"]
2401 error     at installTargetsError (C:\ProgramFiles\nodejs\node_modules\npm\lib\cache.js:719:10)
2401 error     at C:\Program Files\nodejs\node_modules\npm\lib\cache.js:638:10
2401 error     at saved (C:\Program Files\nodejs\node_modules\npm\node_modules\npm-registry-client\lib\get.js:142:7)

即使出现此错误，我也能够手动将 findup-sync 包含在 directnpm install findup-sync@0.1.2中，但这并没有解决我与 Tomcat 实例有关的错误。

它必须与 com.sun:tools.jar 有其他特别的关系...查看我的 POM，但如果有人以前在 JHipster 上经历过这种情况，请给我留言。感谢您的帮助！

这里有3个问题：

我的 Eclipse 配置指向 JRE 而不是 JDK（其中包含正确的 com.sun:tools jar）。然而，为了进行正确的更新，它并不像更新我的 JAVA_HOME 变量并继续前进那么简单......请参见下面的步骤 1-5。
- 描述此问题的 StackOverflow 文章在此处注明：Maven 3 Artifact problem
我的 application-dev.yml 属性文件没有指向生成的数据库。Eclipse 只是在生成连接池时遇到了问题，而不是抛出描述性错误，而是会炸毁。请参阅下面的第 8 步。
我的项目是一个 spring-boot 项目，因此无法在 Eclipse 中的通用 Tomcat 服务器上执行。请参阅下面的第 9 步。

决议摘要

将 %JAVA_HOME% 更改为 JDK
使用以下行更新 eclipse.ini：
- -vm
- C:\Program Files\Java\jdk1.7.0_25\bin\
更新 Eclipse 首选项：'Window > Preferences > Java > Installed JREs' > delete and add new JDK
更新项目属性：'Project > Properties > Java Build Path' > delete old JRE and add new JDK
关闭所有打开的命令提示符和活动服务器（可能正在缓存 %JAVA_HOME% 是什么......我花了一个小时才意识到这一点）
mvn 清洁包
告诉 SureFire 在 POM 构建期间被跳过
确保更新您的 application-dev.yml 文件以指向一个真实的数据库（在 Eclipse 中执行只是表明存在内存丢失的异常，但运行mvn spring-boot:run会为您提供更好的错误报告）。
如果是 spring-boot 应用程序，请将其作为 spring-boot 应用程序运行，而不是直接在 Eclipse 中的 Tomcat Server 上运行。我还没有研究为什么这会如此痛苦，但我稍后会回来。如果您知道，请在评论中添加详细信息。

首先在 Eclipse 而不是 Maven 中运行的问题 - 错误日志非常具有误导性！

java - JHipster Eclipse 项目在“main”中内存不足
