Java 当我尝试在本地Tomcat 8.5上调试Eclipse JEE web项目时，本地主机上的服务器Tomcat v8.5无法启动

我还发现了其他类似的问题。答案似乎是针对那些人的错误，所以我放弃了

回想起来，当我停止这个项目时，我没有这个错误。我不记得在我回到这个项目并得到这个错误之前做过任何改变

我想在本地tomcat 8.5服务器上调试我的web应用程序。在EclipseIDEforEnterpriseJava开发人员版本2019-034.11.0中，我右键单击我的web项目并选择Debug As->Debug on Server。出现一个对话框，我选择手动定义新服务器的选项。我选择TomcatV8.5服务器。我点击Finish按钮。调试窗口中会出现一些红色文本。然后出现一个对话框，说明：

“在本地主机上启动Tomcat v8.5服务器”遇到问题

本地主机上的服务器Tomcat v8.5无法启动

我已经能够使用startup.sh成功地启动tomcat，并且能够使用shutdown.sh成功地关闭tomcat，所以我知道tomcat可以自己工作

我能够在AWS Beanstalk上运行此web项目

下面是它在调试窗口中的说明：

我在Eclipse中检查了一个web应用程序，它也在Tomcat8.5中运行。 tomcat-users.xml路径是[myworkspace]\Servers\tomcat v8.5 Server at localhost config

请尝试以下步骤：

下载全新的tomcat8.5并安装到新文件夹中 为您的项目创建一个全新的工作区。 转到eclipse服务器视图，单击该链接添加服务器 在其中选择ApacheTomcat8.5 选择新的tomcat安装文件夹 将您的web应用程序添加到其中 右键单击新添加的服务器并选择“开始”

---

在这些步骤中，我没有看到任何错误。你能试试吗

在Eclipse WTP中运行Tomcat有不同的方法，在下面的服务器位置部分中配置：

从日志中，您现在应该使用第一个选项，即使用工作区元数据不会修改Tomcat安装，在本例中，Eclipse将运行Tomcat，因为其根文件夹位于配置的服务器路径，即$project_workspace/.metadata/.plugins/org.Eclipse.wst.server.core/tmp3

请注意，这个Tomcat实例与从命令行使用startup.sh启动Tomcat的实例不同。它们具有不同的配置设置。您应该注意到，在定义服务器之后，还创建了一个服务器项目。该项目包含Eclipse运行的这个tomcat实例的配置

因此，在这个服务器项目中打开server.xml并找到MemoryRealm。我相信你在这里设置了一个无效的，这导致了这个问题。因此，请尝试更正它或简单地删除它，例如它将使用默认设置，该设置将引用服务器项目中的tomcat-users.xml

---

另一方面，您可以尝试使用第二个选项使用Tomcat安装控制Tomcat安装。然后Eclipse将运行Tomcat，就像您使用startup.sh运行它一样，我相信它应该可以运行，正如您提到的，它可以使用startup.sh启动

通常开发人员首先在“服务器”选项卡上定义服务器，然后在服务器上运行调试

---

我还怀疑您在eclipse中的项目类型不正确。我建议您检查项目类型。

当项目的某些Jar文件或其他依赖项相关文件损坏时，会发生这种情况。当我在做一个小项目时，我得到了同样的例外。我删除了与项目相关的所有依赖项，并重新安装了它们。它开始为我工作。

---

希望这有帮助

您的tomcat是嵌入tomcat还是外部tomcat服务器？@Justin我不知道这是什么意思。您是否试图找到文件/usr/share/tomcat8/webapps/ROOT/WEB-INF/tomcat-users.xml？我找到了tomcat-users.xml，但不在该路径中。请删除服务器并重置它，或者甚至重新设置整个项目？我不明白。你是什么意思？如果不是外部的，我该怎么称呼我正在使用的东西呢？一些IDE或像Spring boot这样的应用程序有嵌入式web容器。但看起来你的tomcat不是。我在server.xml中搜索了MemoryRealm。在server.xml中找不到的。服务器位置将灰显并禁用。如何更改其中的设置，例如选择使用Tomcat安装？删除服务器，然后重新注册。它将允许您在创建它之后第一次进行选择。这不起作用。仍然是灰色的。我在底部的帖子中添加了内容。“问题”窗格中出现了一些错误。不确定，它始终适用于我。我通常创建一个服务器，但尚未向其中添加任何应用程序，仅在选择要使用的选项后添加应用程序。
