我有一个基本项目，在我的prod服务器Tomcat 7中运行良好。

我在Eclipse中导入了它，创建了一个tomcat 7服务器来运行它，并进行了一些开发。在eclipse中，所有操作都很好，但是当我导出war文件并将其放在prod服务器的webapps文件夹中时，我得到了以下错误：

代码语言：javascript
复制
FAIL - Application at context path /art_current could not be started

有关信息，我的project在Java7下，所以我在1.7中更改了我的项目构建路径和java编译器。

我试图在META文件夹中创建一个context.xml文件：

代码语言：javascript
复制
<Context path="/art_current" />

但仍然有相同的错误

我注意到，当我通过Eclipse导出我的项目时，项目结构发生了改变：

基础项目:

​

​

从Eclipse导出的项目:

​

​

正如我们所看到的，有一些新的文件夹，特别是出现了一个META文件夹，它正常吗？

也许我做错了什么，但我找不到什么

下面是我尝试从tomcat管理器启动我的应用程序时得到的日志：

我找到了以下解决方案：

在日志文件中，我们可以看到：

代码语言：javascript
复制
Unsupported major.minor version 52.0

如我们所见：Unsupported major.minor version 52.0

这是因为我的eclipse用Java1.8编译了我的项目，我的tomcat在1.7中运行。即使我更改了我的项目构建路径和编译器在1.7下的Eclipse( +清理和重建)。

因此，我刚刚将Tomcat版本从1.7改为1.8，现在一切都很好。
