问题描述

好吧，我正在尝试在tomcat中运行我的Web应用程序，但是我收到以下错误：

Well, i'm trying to Run my web application in tomcat, but i got the following error:

我的项目有效，有些类有奇怪的错误，例如：JOIN FETCH表达式不能用标识变量定义。当我运行Maven - > Update Project时，JOIN FETCH ..中的错误消失但我仍然没有启动我的服务器。

My project works with and some classes have strange errors, like this: "JOIN FETCH expressions cannot be defined with an identification variable.". When i run "Maven --> Update Project" the error in "JOIN FETCH.." disappear but i continue don't get start my server.

推荐答案

对于此错误，可能有不同的解决方案。我已经记下那些对我有用的东西了。

For this error, there can be different solutions. I have noted down the ones that had worked for me.

解决方案1。这在部署和调试环境中总会发生。在部署环境中，只需确保您的服务器类路径包含Spring jar库（例如spring-4.0.4.jar）。

Solution 1. This is always happened in deployment and debugging environment. In deployment environment, just make sure your server classpath has included the Spring jar library (e.g spring-4.0.4.jar).

在调试环境中，步骤可能会有所不同来自不同的IDE，但解决方案是一样的。在Eclipse中，开发人员通常会创建一个tomcat，jboss ...无论用于调试的应用程序服务器，只需确保包含正确的Spring jar。

In debugging environment, the steps may vary from different IDE, but the solution is same. In Eclipse, developers usually will create a tomcat, jboss…whatever application server for debugging, just make sure the correct Spring jars are included.

1. 双击调试服务器单击打开启动


2. 配置以访问服务器环境单击类路径选项卡在此处包含Spring jar文件，它还可能需要
   由于Spring依赖，常见的日志jar。


3. 完成后，再次运行
   申请。

。

解决方案2 。如果您使用Maven作为构建工具并使用它来下载依赖项，则可能存在一些jar冲突。因为Tomcat服务器通常提供一些jar，例如servlet-api和jpa-api。所以，如果你再次使用maven包含它们;识别它们会有问题。

Solution 2. If you are using Maven as a build tool and downloading dependencies using it, there can be some jar conflict. Because Tomcat servers normally provide some jars such as servlet-api and jpa-api. So if you again included them using maven; there will be problems in identifying them.

解决方案3 。如果您使用Eclipse作为IDE并使用Maven作为构建工具并使用tomcat作为服务器;记住Tomcat服务器不会查看文件夹内的jar。为此，有一个小技巧，

Solution 3. If you are using Eclipse as your IDE and using Maven as your build tool and tomcat as your server; remember Tomcat server will not look on the jars which are just inside the folders. For that there's a small trick,

1. 右键单击您的项目并选择属性从显示的窗口中

1. Right click on your project and select properties From the displayed window,

选择部署程序集

选择添加

添加Maven依赖项

单击应用并单击确定

希望其中一个解决方案可以帮助您解决问题。快乐编码并确保使用Java。

Hope one of these solutions would help you to solve your problem. Happy Coding and make sure that is using Java.
