tomcat 来自 eclipse 的 7 个项目
tomcat 7 project from eclipse
我有一个在我的产品服务器上运行良好的基础项目Tomcat 7.
我将其导入 Eclipse，为 运行 创建了一个 tomcat 7 服务器并进行了一些开发。
在 Eclipse 浏览器中一切正常，但是当我导出 war 文件并将其放入我的产品服务器上的 webapps 文件夹中时，出现以下错误：
FAIL - Application at context path /art_current could not be started
有关信息，我的 Prod tomcat 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-INF 文件夹中创建一个 context.xml 文件：
<Context path="/art_current" />
但还是出现同样的错误
我注意到一些事情，当我通过 Eclipse 导出我的项目时，项目结构发生了变化：
Basic Project :
Exported project from Eclipse :
我们可以看到，有一些新的文件夹，特别是出现了一个META-INF文件夹，是否正常？
也许我做错了什么，但我找不到什么
编辑
这是我尝试从 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：
Unsupported major.minor version 52.0
正如我们在这里看到的：Unsupported major.minor version 52.0
这是因为我的eclipse在Java 1.8编译了我的项目，而我的tomcat在1.7编译了运行。即使我在 Eclipse 下的 1.7 中更改了我的项目构建路径和编译器（+ 清理和重建）。
所以我刚刚将 Tomcat java 版本从 1.7 切换到 1.8，现在一切正常。
我有一个在我的产品服务器上运行良好的基础项目Tomcat 7.
我将其导入 Eclipse，为 运行 创建了一个 tomcat 7 服务器并进行了一些开发。
在 Eclipse 浏览器中一切正常，但是当我导出 war 文件并将其放入我的产品服务器上的 webapps 文件夹中时，出现以下错误：
FAIL - Application at context path /art_current could not be started
有关信息，我的 Prod tomcat 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-INF 文件夹中创建一个 context.xml 文件：
<Context path="/art_current" />
但还是出现同样的错误
我注意到一些事情，当我通过 Eclipse 导出我的项目时，项目结构发生了变化：
Basic Project :
Exported project from Eclipse :
我们可以看到，有一些新的文件夹，特别是出现了一个META-INF文件夹，是否正常？

我找到了以下解决方案：
在日志文件中我们可以看到：
Unsupported major.minor version 52.0
正如我们在这里看到的：Unsupported major.minor version 52.0
这是因为我的eclipse在Java 1.8编译了我的项目，而我的tomcat在1.7编译了运行。即使我在 Eclipse 下的 1.7 中更改了我的项目构建路径和编译器（+ 清理和重建）。
所以我刚刚将 Tomcat java 版本从 1.7 切换到 1.8，现在一切正常。
