Question

我在SpringMVC中使用了百里香，并且试图将图像加载到视图中。

在项目中，我的图像位于MyApp / WebContent / resources / images

我尝试过：

<img src="WebContent/resources/images/photo.png" 
    class="img-responsive" width="100" height="100">
</div>

然后出现下一个错误：

No mapping found for HTTP request with URI [/MyApp/WebContent/resources/images/photo.png] in DispatcherServlet with name 'thymeleaf'

我也尝试过将图像放在下一个路径上：

MyApp/main/src/resources/images

MyApp/main/src/resources/static/images

MyApp/WebContent/WEB-INF/resources/images

MyApp/WebContent/WEB-INF/images

但它永远都行不通

我进行编辑以添加项目中的依赖项。

来自pom.xml的依赖项：

Answer 1

您可以将图像放在main / src / resources / static / images中，图像src应该是：

<img src="/images/photo.png" class="img-responsive" width="100" height="100"/>

如果您不将/放在开头，它将尝试以url的形式访问它，而不是在静态文件夹中进行搜索。

更新：请看一下这个示例项目：

https://github.com/adinafometescu/tutorials/tree/master/spring-boot-image

我用弹簧靴和百里香叶创建了一个示例项目，以显示简单的图像

Answer 2

尝试在百里香中使用它 1）您必须从main /资源文件夹中获取静态内容，然后在您的视图中这样做尝试过：

<img src="-(tilde 
 symbol)/../public/static/images/photo.png" 
    class="img-responsive" width="100" height="100">
 </div>

Answer 3

在配置文件中声明这样的静态资源

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"<your Base package-name>"}
public class WebConfig implements WebMvcConfigurer {

// Declare your Static resources
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/Webcontent/**).addResourceLocations("/")
.setCachePeriod(31556926);
}

 then put img tag <img src="/WEB-INF/resources/images/photo.png" width="200px" height = "100px"/>

或XML：

<mvc:resources location="/Webcontent/" mapping="/webcontent/**" /> //not tested but see if it works!!

这是Java配置（大多数情况下都可以使用！），因为cuz XML Config太复杂了，试试这个，让我知道..欢呼

无法在百里香和春天加载图像
