Springboot通过controller跳转html页面踩的坑

Posted 2023-05-04

参考技术A @RestController

public class LoginController

//当注解用@Controller时 直接return "页面名称";

//    @RequestMapping("/login")

//    public String usrLogin()

//        return "index";

//   

//

//    @RequestMapping("/login-error")

//    public String loginError()

//        return "login-error";

//   

    @RequestMapping("/login")

public ModelAndViewusrLogin()

return new ModelAndView("index");

   

@RequestMapping("/login-error")

public ModelAndViewloginError()

return new ModelAndView("login-error");

   

新建的springboot跳转页面404的问题

从start.spring.io下载的maven项目,功能选择的web,部署到本地后controller断点能击中，但retrun后提示404，同时后台打印一条error日志

Cannot forward to error page for request [/] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false

解决方法

　　pom.xm引入

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

就好了。
