我有 Spring MVC 应用程序，我使用的是 Java 配置，没有 XML。我的 JSP 无法访问 CSS 文件。我用谷歌搜索了一整天，几乎尝试了一切。当我检查我的页面时，控制台中出现错误 - 无法加载资源:服务器响应状态为 404(未找到)我正在使用 Wildfly 服务器。
SpringConfig:
package com.library.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "com.library")
public class SpringConfig extends WebMvcConfigurerAdapter {
@Bean
public ViewResolver viewResolver(){
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/resources/views/");
resolver.setSuffix(".jsp");
return resolver;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/static/css/");
}
}
DispatcherInitializer:
package com.library.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class DispatcherInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {SpringConfig.class};
}
@Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] {"/"};
}
}

最佳答案
根据您随问题发布的信息，我首先对您的元素做出一些假设/猜测:
- 您的元素设置为
Java元素。 - 您正在使用
Maven运行您的构建，并将包生产设置为:<packaging>WAR</packaging>. - 成功构建后，
style.css的副本最终位于以下位置:/target/libraryproject/WEB-INF/classes/static/css/style.css.
我认为前 2 个猜测很安全，但第 3 个猜测可能不正确，具体取决于您的build设置方式。例如，libraryproject目标路径的一部分实际上可能是这样的:libraryproject-0.0.1-SNAPSHOT .如果是这样，您可能需要对以下内容进行一些调整，所以请记住这一点，但这里是我的建议:
第 1 步:
更改现有的SpringConfig.addResourceHandlers方法，删除 DEVELOPMENT_TIME透视，重构 resourceLocations定义 RUNTIME 的参数规范，所以在RUNTIME , 静态资源从根加载 classpath在WAR文件:
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("classpath:/static/");
}
第 2 步:
更新样式表 link规范 login.jsp以便它加载 style.css来自 WAR文件 resourceLocation在步骤 1 中定义:
<link href="<c:url value="css/style.css"/>" rel="stylesheet"/>
注意路径是如何相对于 /static/ 的目标构建位置中的资源根位置，在 WAR 中保持不变.
在这 2 项更改之后，我认为您将能够正常运行。但愿如此。如果没有，请告诉我，我会尽力帮助您。我记得有过同样的问题，苦苦思索了几个小时，还有令人沮丧的 404 错误。这很痛苦 - 希望这可以帮助您解决问题 -
