在apache tomcat上部署war文件时不加载CSS和JS文件-Java 学习之路

我正在使用spring-boot-starter-web-mvc进行初始开发 . 当我在服务器上部署war文件时，它不会加载css和js文件，但是当我使用spring boot运行相同的代码时，它运行正常 . 下面是加载js和css文件的目录结构和配置 . 任何人都可以让我知道如何解决问题？仅使用基于java的项目配置 . 在部署项目之前，我在doc中引用了8.1.1，并使用了与下面相同的pom文件配置 .

Directory structure

配置文件 -

public class ViewWebAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // configuration for assets/ static files
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/jsp/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

    @Bean
    public ResourceBundleMessageSource messageSource() {
        ResourceBundleMessageSource rb = new ResourceBundleMessageSource();
        rb.setBasenames(new String[] { "validation" });
        return rb;
    }

}

使用如下 spring 标签加载js和css -

<%@taglib prefix="spring" uri="http://www.springframework.org/tags"%>

<spring:url value="/resources/assets/js/custom.min.js" var="customJS" />
<script src="${customJS}"></script>

<link href="${customFieldAgent}" rel="stylesheet"/>
<spring:url value="/resources/assets/css/customfieldAgent.css" var="customFieldAgent" />

以下是服务器日志 -

17：03：10.014 [http-nio-8080-exec-7] DEBUG org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - 找不到[/ $]的处理程序方法17:03 ：10.014 [http-nio-8080-exec-7] WARN org.springframework.web.servlet.PageNotFound - 在DispatcherServlet中找不到带有URI [/ ui / $％7BstarrrJS％7D]的HTTP请求的映射，名称为“dispatcher”17 ：03：10.014 [http-nio-8080-exec-7] DEBUG org.springframework.web.servlet.DispatcherServlet - 成功完成请求17：03：10.018 [http-nio-8080-exec-4] DEBUG org.springframework . web.servlet.DispatcherServlet - 名为'dispatcher'的DispatcherServlet处理[/ ui / $％7BcustomJS％7D]的GET请求17：03：10.018 [http-nio-8080-exec-4] DEBUG org.springframework.web.servlet .mvc.method.annotation.RequestMappingHandlerMapping - 查找路径/ $ 的处理程序方法17：03：10.019 [http-nio-8080-exec-4] DEBUG org.springframework.web.servlet.mvc.method.annotation .RequestMappingHandlerMapping - 没找到汉用于[/ $]的dler方法17：03：10.019 [http-nio-8080-exec-4] WARN org.springframework.web.servlet.PageNotFound - 没有找到带URI的HTTP请求的映射[/ ui / $ DispatcherServlet中的％7BcustomJS％7D]，名称为“dispatcher”17：03：10.019 [http-nio-8080-exec-4] DEBUG org.springframework.web.servlet.DispatcherServlet - 已成功完成请求

试试这种方式它对我有用 .

Project Structure:

src/main/webapp/static/[css,js,images]
src/main/webapp/WEB-INF/views/[for all .jsp pages]

Configuration

@Configuration
@ComponentScan(basePackages = "parent package name where all packages reside")
public class ApplicationConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/views/");
        viewResolver.setSuffix(".jsp");
        registry.viewResolver(viewResolver);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // when static resources are inside resources folder under WEB-INF
        // registry.addResourceHandler("/resources/**").addResourceLocations("/WEB-INF/resources/");

        // when static resources are inside static folder under webapp
        registry.addResourceHandler("/static/**").addResourceLocations("/static/");
    }
}

让 DispatcherServlet 知道怎么收拾东西......

import javax.servlet.Filter;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ApplicationInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { ApplicationConfiguration.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }     
}

现在在视图上调用这些...

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"  
"http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
        <link href="<c:url value='/static/css/application.css' />" rel="stylesheet"></link>
    </head>

Add this in your pom.xml

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
    </dependency>

希望这会帮助你 .

在我的Spring Boot项目中，我尝试将WAR文件部署到TOMCAT中，但它无法识别资源路径，它会抛出 404 File not found error ，但是当我作为SpringBootApplication运行时，它可以正常工作，只有在作为WAR文件部署到TOMCAT时才会发出 . 所以最后我发现了这个问题，现在它在我的项目结构上完美运作

将这些行添加到 application.properties 文件中
```
spring.resources.add-mappings=true
spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/
```
我来自https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html

它完美地工作......

对于这个js，图像，css或来自战争文件图像或任何文件的外部都可以显示，并且通过使用下面的行获得访问权限对两个场景是通用的

spring.resources.add-映射=真

对于spring boot war文件或任何spring文件来访问或显示这个你必须放入application.properties文件或任何属性文件

spring.resources.static-位置=类路径：/ META-INF /资源/，类路径：/资源/，类路径：/静态/

对于外部访问文件或显示图像的外部文件，您可以将其作为

spring.resources.static-位置=文件：/// C：/ XXXXXXXXX / XXXXXXXXX

AS说道，它正在努力尝试它
