tomcat——静态资源映射

rehoni / 2021-12-02

方法一

tomcat访问外部的资源，配置静态资源映射

https://www.cnblogs.com/iyangyuan/p/3316444.html

<?xml version="1.0" encoding="UTF-8"?>
<Context crossContext="true" docBase="/users/ems/zhsbdStatic" path="/zhsbdResources" reloadable="true"> </Context>

server.xml的Host标签下

<Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
		<!-- 增加虚拟路径，供访问本地图片-->
		<Context path="/upload_file" docBase="D:/upload/img" reloadable="false" ></Context>

</Host>

方法二

只适合jar包或者打包了资源的war包，未打包资源的war包丢入服务器的tomcat，是无法通过配置来访问外部资源的

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    /**
     * Add handlers to serve static resources such as images, js, and, css
     * files from specific locations under web application root, the classpath,
     * and others.
     *
     * @param registry
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // addResourceHandler 服务的相对路径
        // addResourceLocations 本机/部署环境的绝对路径，注意Windows下前缀不同 file:///D:/files/
        registry.addResourceHandler("/oiisResources/**").addResourceLocations("file:/users/ems/websophic/static/");
    }
}
