IntelliJ IDEA - SpringBoot 项目/无法找到对 go 的声明

Question

I am fairly new to Java and Spring and I have troubles with writing a simple application.我是 Java 和 Spring 的新手，我在编写一个简单的应用程序时遇到了麻烦。

Thing is, IntelliJ does not see my.jsp files that are in the project.问题是，IntelliJ 看不到项目中的 my.jsp 文件。 The application works, but I am not getting help from IntelliJ.该应用程序有效，但我没有从 IntelliJ 获得帮助。 I also can't use model I created in my HomeController class in my homepage.jsp with forms and modelAttribute, as it becomes red and does not support me writing the code.我也不能使用我在主页的 HomeController class 中创建的 model。jsp 和 forms 和 modelAttribute，因为它变成红色并且不支持我编写代码。

.jsp files are in webapp/WEB-INF/jsp/ .jsp 文件在 webapp/WEB-INF/jsp/

I have application.properties file with:我有 application.properties 文件：

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

Here are my files:这是我的文件：

HomeController.java家庭控制器.java

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String hello(Model theModel){

        Credentials theCredentials = new Credentials();

        theModel.addAttribute("credentials", theCredentials);

        return "homepage";
    }
}

Credentials.java凭据.java

public class Credentials {

private String username;
private String password;

public Credentials() {
}

public String getUsername() {
    return username;
}

public void setUsername(String username) {
    this.username = username;
}

public String getPassword() {
    return password;
}

public void setPassword(String password) {
    this.password = password;
}

} }

homepage.jsp主页.jsp

Maybe you have something wrong with your web-inf directory mark. 也许您的web-inf目录标记有问题。 Right click on webapp -> mark directory as -> sources root 右键单击webapp->将目录标记为-> Sources root
