这个错误信息中的异常是 `java.lang.ClassCastException: com.mflex.job.entity.Job cannot be cast to com.mflex.job.entity.Job`,看起来是一个类转换异常。具体来说,你的代码中尝试将一个 `com.mflex.job.entity.Job` 对象转换为 `com.mflex.job.entity.Job`,但这两个类型看起来是相同的,因此出现了转换异常。
这种情况通常是由于类加载器问题引起的。可能有两个不同的类加载器加载了同一个类,从而导致 JVM 中存在两个不同的类实例,尽管它们的名称相同。这种情况下,当你尝试将一个实例转换为另一个实例时,会出现类转换异常。
解决这个问题的方法是检查你的应用程序的类加载器是否正确。如果你使用了多个类加载器,请确保它们都能够正确加载你的类,并且不要重复加载同一个类。如果你不确定这些问题,建议你仔细检查你的应用程序的类路径和类加载器,并尝试进行调试。

com.alibaba.fastjson.JSONException: can not cast to : cc.mrbird.febs.system.entity.User
This error occurs when you try to cast an object of a different type to the User class. The FastJSON library is unable to convert the object to the User class because it does not have the required properties and methods.
To resolve this error, you need to ensure that the object you are trying to cast is of the correct type. You can also check the structure and properties of the User class to ensure that it matches the object you are trying to cast.

Layui FEBS是一款简单高效的后台权限管理系统,使用Spring Boot和Layui构建。FEBS-Shiro是其中的一个技术选型,后端采用了Spring Boot 2.2.1、Mybatis-Plus、MySQL 5.7.x、Hikari、Redis和Shiro 1.4.2。前端使用了Layui 2.5.5、Nepadmin、formSelects 4.x多选框、eleTree树组件和formSelect.js树形下拉。
对比一下,在后端代码中,有一个findProjectDetailPage方法用于分页查询项目详情。该方法接收一个QueryRequest对象和一个Project对象作为参数,其中QueryRequest用于分页查询,Project用于条件查询。在方法中,首先对排序进行处理,将驼峰命名法转为下划线分割,并根据排序方式(升序或降序)进行排序设置。然后,使用baseMapper的findProjectDetailPage方法进行分页查询,并返回查询结果。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
