在端口8081上击中URL“ / getEmployees”时，我没有得到字符串“ this is employee list”作为响应，而是得到了字符串“ getEmployees” 从Controller类返回，这意味着控制器没有重定向到应该打印“这是员工列表”的jsp页面。...请有人帮我吗？对我来说要花很多时间。...

Answer 1

@RestController：是@Controller和@RestponseBody的组合。因此，从REST控制器方法返回的所有内容都将以String（{JSON/XML）的形式返回，因为这是REST Full Web Services所期望的。

@Controller：创建模型对象的Map并查找返回值的视图。

因此，从@RestController更改为@Controller应该会对您有所帮助。

是的，需要在Application类上使用@EnableWebMvc。
