在 Spring MVC 3.0.2 中显示图像

Question

我正在使用 Spring 3.0.2 当我尝试显示图像时，我得到的只是一个带有红十字的框。我也尝试过使用

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

但我得到一个错误
"匹配的通配符是严格的，但是找不到元素'mvc:resources'的声明"

我也尝试添加 Spring V4 jar，但它们现在与以前的 jar 冲突。

这是我的 spring-servlet.xml

任何关于如何显示我的图像的帮助将不胜感激

Answer 1

您的 mvc:resources 设置与您的 img src 标签不匹配。 首先，改变

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

到

<mvc:resources mapping="/resources/**" location="/WEB-INF/resources" /> 

然后将您的静态文件（或文件夹）移动到 /WEB-INF/resources 目录下。

然后将img标签的src更正为/resources/path/to/image开头。

但是如果你的图像不需要保护，你可以让静态文件保持原样，然后将 mvc:resources 更改为

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

将img标签的src改为/resources/images/path/to/image
