根据您随问题发布的信息，我首先对您的项目进行一些假设/猜测：

您的项目被设置为

Java

项目

您正在使用

Maven

运行构建，包生产设置为：

WAR

成功构建后，

style.css

的副本将出现在以下位置：

/target/libraryproject/WEB-INF/classes/static/css/style.css

我认为我在前两个版本中非常安全，但是第三个猜测可能不正确，这取决于构建的设置方式。例如，目标路径的

libraryproject

部分实际上可能类似于：

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，因此请记住这一点，但以下是我的建议：

步骤1：更改现有的

SpringConfig.addResourceHandlers

方法，删除

DEVELOPMENT\u TIME

透视图，重构

resourceLocations

参数以定义

运行时

规范，以便在

运行时

，静态资源从

WAR

文件中的根

classpath

加载：

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/resources/**")
                .addResourceLocations("classpath:/static/");
}

步骤2：更新

login.jsp

中的样式表

link

规范，以便从步骤1中定义的

WAR

文件

resourceLocation

加载

style.css

：

<link href="<c:url value="css/style.css"/>" rel="stylesheet"/>

请注意路径如何相对于目标生成位置中的

/static/

资源根位置，该位置在

WAR

中保持不变

在这两次改变之后，我想你会恢复正常的。我希望如此。如果没有，请告诉我，我会尽力帮你。我记得我也遇到过同样的问题，苦干了几个小时，还有令人沮丧的404错误。这很痛苦-希望这能帮助您解决问题-

似乎

webapp

位于

src

目录下。

webapp

与

main

处于同一级别。这个结构是由maven生成的。试着使用

我检查了这3个点，它们都正常。我尝试了这两个步骤，但当我插入

时，它给出了该值的错误-无法解析目录。如果您能提供更多详细信息，我将帮助您了解发生了什么-
