Question

我一直在浏览几乎所有与我的问题相关的帖子，并尝试了所有发现的解决方案，并且这个问题不断出现。

我正在开发一个Web应用程序，几乎所有页面都将包含在内，但是当我尝试将Controllers与任何JSP连接时，每次都会显示此消息，因此我创建了一个只有一个表和一个表的新项目。几页，并且仍然会出现相同的“错误”，但仅在加载了某些信息的页面上，我尝试了一个非常简单的页面，并且可以正常工作

Whitelabel错误页面

此应用程序没有针对/ error的显式映射，因此您将其视为备用。

发生意外错误（类型=未找到，状态= 404）。没有可用消息

Answer 1

根据您点击时的Controller映射

localhost:8080/ => inicio page will load
localhost:8080/listcte => indexpac page will load
localhost:8080/newcte => nuevopac page will load

现在让我们看看您在尝试什么

localhost:8080/listado =>将引发错误页面，因为在Controller类中找不到该URL的映射。

localhost:8080/newcte =>应该加载nuevopac页面。检查控制台是否有错误，请添加nuevopac代码。可能是JSP抛出一些错误。

Answer 2

在Controller客户端类@Controller中替换为@RestController

没有消息可用JSP SpringBoot

Whitelabel错误页面
