JSP 文件无法链接

发布于 2025-01-16 19:16:50 字数 5184 浏览 0 评论 0原文

我在同一文件夹中有 2 个 JSP 文件。 src/main/webapp/WEB-INF/jsp.jsp.jsp

我试图在本地主机上将两个页面链接在一起，它将读取我的索引页面，但不会链接到我的添加库存 jsp。

控制器：


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;


import com.project.domain.Vehicle;
import com.project.service.VehicleService;

@Controller
public class VehicleController {
    
    @Autowired
    VehicleService vehicleService;

    @GetMapping("/")
    public String welcome(Model model) {
        return "index";
        
    }
    
    @GetMapping("/add-inventory")
    public ModelAndView addInventory(Model model) {
        return new ModelAndView("add-inventory", "vehicle", new Vehicle());
    }
    
    @PostMapping("/add-inventory")
    public String handleAddInventory(Model model, @ModelAttribute("vehicle") Vehicle vehicle, HttpSession session) {
        vehicleService.saveVehicle(vehicle);
        model.addAttribute("newvehicle", vehicle);
        return "index";
}
}

索引文件：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
</head>
<body>
Hello World

<a href="/add-inventory">Add Inventory</a> <br>



</body>
</html>

添加库存文件： add-inventory 文件：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Add Cars</title>
</head>
<body>
Why is this not working

</body>
</html>

我尝试更改方法以返回这样的字符串，但它也不起作用。

@GetMapping("/add-inventory")
    public String welcome(Model model) {
        return "add-inventory";

jsp页面错误图片

原文

I have 2 JSP files in the same folder. src/main/webapp/WEB-INF/jsp.

I'm trying to link the two pages together on a local host, it will read my index page, but will not link to my add-inventory jsp.

Controller:


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.servlet.ModelAndView;


import com.project.domain.Vehicle;
import com.project.service.VehicleService;

@Controller
public class VehicleController {
    
    @Autowired
    VehicleService vehicleService;

    @GetMapping("/")
    public String welcome(Model model) {
        return "index";
        
    }
    
    @GetMapping("/add-inventory")
    public ModelAndView addInventory(Model model) {
        return new ModelAndView("add-inventory", "vehicle", new Vehicle());
    }
    
    @PostMapping("/add-inventory")
    public String handleAddInventory(Model model, @ModelAttribute("vehicle") Vehicle vehicle, HttpSession session) {
        vehicleService.saveVehicle(vehicle);
        model.addAttribute("newvehicle", vehicle);
        return "index";
}
}

index file:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
</head>
<body>
Hello World

<a href="/add-inventory">Add Inventory</a> <br>



</body>
</html>

add-inventory file:
add-inventory file:

<head>
<meta charset="UTF-8">

<body>

</body>

I've tried changing the method to return a string like this and it does not work either.

@GetMapping("/add-inventory")
    public String welcome(Model model) {
        return "add-inventory";

解决了！

我必须将此代码添加到应用程序中。但不知道 @Componentscan 和 @Override 方法实际上做了什么。任何解释都会很棒。哈哈

@SpringBootApplication
@ComponentScan(basePackages="com.project")
public class CarAppApplication extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(CarAppApplication.class);
    }
    
    public static void main(String[] args) {
        SpringApplication.run(CarAppApplication.class, args);
    }

SOLVED!

I had to add this code to the Application. No clue what the @Componentscan and @Override methods actually do though. Any explanation would be great. Haha

@SpringBootApplication
@ComponentScan(basePackages="com.project")
public class CarAppApplication extends SpringBootServletInitializer{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(CarAppApplication.class);
    }
    
    public static void main(String[] args) {
        SpringApplication.run(CarAppApplication.class, args);
    }
