请问，在eclipse spring如何添加配置文件

Posted 2023-04-17

配置完用户库后，怎么找到写配置文件的地方？我怎么找不到？我刚开始学J2EE，还希望各位不吝赐教
还有，那个log4j.properties文件在哪写？

参考技术A log4j.properties,放在项目的scr目录下
log4j.properties是要自己写的(新建一个log4j.properties文件),网上有很多参考模板.
配置文件是xml格式的,在程序里面调用就可以了(注意路径)本回答被提问者采纳 参考技术B 可以在help->eclipse
marketplace安装插件1
,spring
tool
suit
(sts)
2,
hibernate
tools
将这两个插件安装好，再输入class名就会有提示。

如何在 Eclipse 和 Window 10 上配置 AWS SAM

【中文标题】如何在 Eclipse 和 Window 10 上配置 AWS SAM

【英文标题】：How to configure AWS SAM on Eclipse and Window 10

【发布时间】：2019-05-23 19:41:31

【问题描述】：

我正在使用 STS 4 (https://spring.io/tools) 并添加了 Eclipse AWS 工具包 (https://marketplace.eclipse.org/content/aws-toolkit-eclipse)。

重启 STS 后，我们可以看到一切正常。

现在我已经在本地安装了 AWS SAM CLI

并配置了我们拥有 sam.exe 的路径

我在本地安装了 Java 8 和 Python 2.7 和 3.6 以及 docker。

现在创建了 AWS Java serverless 项目 maven install 并尝试运行 sam local

更新：

当我尝试运行 SAM-CLI 时，它的工作和返回响应。

我想知道是否有人解决了这个问题？

【问题讨论】：

你能解决这个问题吗？我得到完全相同的错误

【参考方案1】：

遇到同样的问题，进行了以下更改并能够继续...

在图片中的“并运行配置”部分中。 确保您已展开“高级”部分并添加了所需的信息，

AWS 配置

SAM 本地配置（应该设置）。

还可以尝试添加执行以下操作。 在您的文件夹中 C:\Users\YOUR_USER.aws 您应该看到两个文件、凭据和配置。 我没有文件配置，所以我创建了它并添加了以下内容：

[default]
region=YOUR_REGION

我还在凭据文件的 [用户名] 下添加了以下行：

region=YOUR_REGION

我保存并重新启动所有内容并使其正常工作。 现在我还有一些其他问题。但它们特定于 JSON 解析。

【参考方案2】：

有同样的问题。

首先你应该打开命令行并运行 where sam 如果您发现路径包含任何空格，例如，如果路径中有“程序文件”，则卸载 samcli 并重新安装。确保其路径不包含任何空格，例如：C:\Amazon\SAMCLI。当你完成安装 samcli 后，在 cmd 中重新运行之前的代码，并复制路径并粘贴到 eclipse 中。

其次，您应该按照 Dimman 的建议创建配置文件。您可以通过运行使用 awscli 来执行此操作 aws configuration

这将自动创建文件。保存并重新启动，一切都应该没问题。

祝你好运。

【讨论】：

您也可以将“c:\Program Files\...”部分替换为“C:\Progra~1\...”部分而不必重新安装SAM？我在我的 windows/eclipse 工作站上尝试过，它似乎没有帮助，但它可能对某些人有用？

我从 dos 做了“where sam”，它是 sam.cmd 版本（不是 sam.exe）版本？这些似乎都不起作用？有关如何解决此问题的任何进一步建议？
