同学你好，

1、在MEvaluationController中配置的路径为/management/evaluation，那么在如下路径这里需要添加/evaluation

2、这是警告信息，对程序运行没有影响，可忽略不计

祝学习愉快~

同学你好，图书界面没了，建议同学查看访问路径是否正确，控制台是否有报错呢，在该问答中没有发现同学说的"还有一个提问"是指哪里，建议同学新开问答，将对应的报错以及访问的路径贴出，便于老师测试运行

同学你好，404是访问路径不正确的，同学在MEvaluationController中配置的路径为/management/evaluation，但在访问时路径缺少/evaluation

这里建议同学检查自己的左侧导航栏那里的路径引入是否书写错误呢？

同学你好，贴出的信息并不能看出来问题所在，建议将左侧导航栏那里的路径截图看一下，便于老师检查
