Any static resource is also look for a URL Mapping in spring mvc, so static resources should be defined in the springmvc-servlet.xml.
任何静态资源也是在 spring mvc 中寻找 URL Mapping，所以静态资源应该在springmvc-servlet.xml.
Add the following entry to your MVC configuration. I assume that your static files in resourcesfolder.
将以下条目添加到您的 MVC 配置中。我假设您的文件resources夹中的静态文件。
<mvc:resources mapping="/resources/**" location="/resources/" />
then static files can be accessible from the page.
然后可以从页面访问静态文件。
<img src="/resources/images/logo.jpg" />

try
尝试
<img src="/MyApp/WebContent/images/logo.jpg" />
Even though it is a Spring MVC app, it should still deploy as a normal webapp. Check your deployment to make sure, and also use the browser to test loading.
即使它是一个 Spring MVC 应用程序，它仍然应该作为一个普通的 web 应用程序进行部署。检查您的部署以确保，并使用浏览器测试加载。

To avoid to have to indicate explicitly the context path you can use jstl core and do it like that
为了避免必须明确指示上下文路径，您可以使用 jstl core 并这样做
<img src="<c:url value="/images/logo.jpg"/>"/>
You can also check this thread about spring ressource and path
您还可以查看有关 spring 资源和路径的此线程

我把images文件夹放在WEB-INF目录下，在spring-dispatcher-servlet.xml文件中完全配置后，我使用了这个img src:< img src=" projectname/../images/logo.jpg" />我的jsp页面，图片终于显示出来了。

To make it work I had to do in spring config:
为了使它工作，我必须在 spring 配置中做：
<mvc:resources mapping="/resources/**" location="/resources/" />
In JSP:
在 JSP 中：
<spring:url value="/resources/images" var="images" />
<img src="${images}/back.png"/>

in springmvc-servlet.xml you should add <mvc:resources location="/WEB-INF/images/" mapping="/images/**" />and in jsp <img src="images/logo.jpg" />and you should create a folder under web-inf which is named images and in the web.xml your servlet mapping shoul be like that <url-pattern>/</url-pattern>.
在 springmvc-servlet.xml 中，您应该<mvc:resources location="/WEB-INF/images/" mapping="/images/**" />在 jsp 中添加和，<img src="images/logo.jpg" />并且应该在 web-inf 下创建一个名为 images 的文件夹，在 web.xml 中，您的 servlet 映射应该是这样的<url-pattern>/</url-pattern>。
