Файл css не относится к моему jsp (проект maven / spring / hibernate)

/ 27 февраля 2020

Я создал небольшой проект для заполнения формы (Имя + страна) и после проверки мы составляем список таблицы в базе данных. Проект представляет собой веб-приложение с Maven. Я интегрировал Spring + Hibernate для управления моей базой данных. Однако я не могу применить файл css к jsp и не могу отобразить изображение. Я не могу понять, как я могу решить мою проблему.

Структура проекта:

добавить spring-web-config. xml в WEB-INF: 

<beans xmlns="http://www.springframework.org/schema/beans"

Я не вижу никакой конфигурации сопоставления ресурсов в вашем коде.

Вы можете добавить spring-web-config.xml внутри WEB-INF со следующим содержимым 

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans     
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">

    <mvc:resources mapping="/resources/**" location="/resources/"  />


</beans>

Любые запросы из этого шаблона URL /resources/**, Spring будет искать ресурсы из /resources/ путь.

Использовать в JSP 

<link href="<c:url value="/resources/css/main.css" />" rel="stylesheet">

or

<script src="<c:url value="/resources/js/main.js" />"></script>

Подробнее см. здесь

Вариант 2:

Вы можете попробуйте добавить строку mvc:resource в существующую строку spring.xml
