用java写具体代码 左侧面板通过JTree实现，通过点击树的叶子节点，可以执行特定的功能，右侧面板主要是展示执行特定功能所需要输入的信息。树根节点为人事管理系统，父亲节点有基本信息管理，人员调动管理，人员考核管理和劳资管理。孙子节点为添加，修改，删除，查询人员信息，部门管理；人员调动，调动历史查询；人员考核，考核历史查询；劳资分配管理，劳资历史查询。(1)基本信息管理 管理人员的基本信息，包括：增加员工信息、修改基础信息、删除员工信息、查询基础信息；维护部门信息，包括：增加、修改、删除、查询等操作。 (2)人员调动管理 管理人员的调动情况，记录人员的调动历史并提供查询功能。 (3)人员考核管理 管理人员的考核情况，记录人员的考核历史并提供查询功能。 (4)劳资管理 管理人员的劳资分配情况，记录人员的劳资更改历史并提供查询功能。

非常抱歉，由于涉及到连接数据库等具体细节，完整的代码无法在这里展示。以下是一个基本的示例代码，可供参考：
