springboot项目配置虚拟路径问题

1. 如果使用springboot内置的tomcat时

@Configuration
public class WebTomcatVirtualPathConfig implements WebMvcConfigurer {

    @Value("${tomcat.virtual.path}")
    private String resourceHandler;

    @Value("${basePath}")
    private String resourceLocations;

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler(resourceHandler).addResourceLocations("file:///" + resourceLocations + "/");
    }

}

application.properties文件中增加：

#访问该链接时，经过静态资源路径
tomcat.virtual.path=/upload/virtual/**
#文件在磁盘上实际存储路径
basePath=C:/Users/mawt/Desktop/im/upload-basepath

测试：访问图片路径为http://192.168.1.145:8088/upload/virtual/10047.jpg

1. idea中使用外部tomcat启动时（跟上面的配置没有关系）

在tomcat的conf/server.xml中增加如下内容（加粗内容）：

 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
             <!-- 设置图片虚拟路径[访问时路径为/upload/virtual] -->  
            <Context path="/upload/virtual" docBase="C:/Users/mawt/Desktop/im/upload-basepath" reloadable="true" />  

        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->

        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

      </Host>

打上勾勾，如此便可以实现
