我在spring上下文文件中对图像文件进行了映射,如下所示:
<mvc:resources mapping="/images/**" location="/WEB-INF/images/" />
我对此进行了测试,以直接访问浏览器地址栏中 url 中的图像:hhttp://host:port/ManageDepartments/images/oracle.PNG
它在浏览器上呈现请求的图像,但为什么它阻止弹簧控制器 url 为用户请求提供服务。在 spring 上下文文件中对图像进行 url 映射后,当我在 url 下方尝试时,它返回 404 错误。
http://host:port/ManageDepartments/department/
在上下文文件中进行图像映射后无法获取部门主页!
对于jsp,下面是spring配置文件中的配置:
<bean id="jspViewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/"
p:suffix=".jsp" />
下面是项目结构:
任何建议都非常感谢!

在控制台中,我没有看到任何错误,但是在浏览器中,当我点击 hhttp://host:port/ManageDepartments/department/ 时,我得到了 HTTP 状态 404,该页面之前用于获取部门主页。
