Question

当我尝试在Eclipse中打开hibernate透视图时，我收到上述错误，并带有以下堆栈跟踪：

我查看了网站，我知道问题是关于sfl4j包含，但不幸的是我试图排除它，更新它，添加一个依赖项，但每次尝试都失败了。

我可以从依赖层次结构中看到的版本是1.6.1，与hibernate核心pom中的版本相同（但在那个版本中，范围是test。

该库包含该类和方法，但我不知道为什么hibernate工具无法找到它们。

我尝试使用Spring Tool Suite ide，并使用全新的Eclipse Eclipse安装。

我的想法已经不多了。：（

Answer 1

检查你的项目pom和eclipse配置：你有两个不同版本的log4j / slf4j。

Answer 2

问题在于类路径中的相同jar的两个或更多版本，如David所示。

在这种情况下，你可以试试这些：

•您的hibernate工具插件（＆lt; eclipse_directory＆gt; / plugins /）和您的项目maven存储库（＆lt; user_directory＆gt; /。m2 / repository / org / slf4j）具有不同的SLF4J jar版本。在这两个文件夹中保持相同的版本（读取类路径）。在这两个中保留最新的一个并删除旧的。这是一个肮脏的黑客，但是保持jar版本同步的可接受方式。

•另一种（更好的）方法，将数据访问对象保存在单独的项目中。创建一个简单的maven POJO项目，并通过hibernate工具自动生成代码。将此项目导入到您正在维护业务逻辑的项目中。这是大型项目中的标准设计，好的部分是，您不必遭受版本冲突。
