nginx 虽然简单，但是总要多装一个服务，多个风险。话不多说，直接上代码！！

1.引入jar包

        <dependency>
         <groupId>org.mitre.dsmiley.httpproxy</groupId>    
           <artifactId>smiley-http-proxy-servlet</artifactId>
           <version>1.7</version>  
        </dependency>

2.在yml添加配置

#代理文件服务为例
proxy:
  #上传
  uploading:
    servlet_url: /uploading/*
    target_url: http://192.168.0.142/file
  #下载
  download:
    servlet_url: /download/*
    target_url: http://192.168.0.142/files

3.配置类

package com.kc.framework.config;


import org.mitre.dsmiley.httpproxy.ProxyServlet;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class SolrProxyServletConfig{

    // 上传
    @Value("${proxy.uploading.servlet_url}")
    private String servletUrlUploading;
    @Value("${proxy.uploading.target_url}")
    private String targetUrlUploading;

    // 下载
    @Value("${proxy.download.servlet_url}")
    private String servletUrlDownload;
    @Value("${proxy.download.target_url}")
    private String targetUrlDownload;

    @Bean
    @SuppressWarnings(value={"unchecked", "rawtypes"})
    public ServletRegistrationBean proxyServletRegistrationDownload(){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new ProxyServlet(), servletUrlDownload);
        //这里名字必须不一样
        registrationBean.setName("suitDownload");
        registrationBean.addInitParameter("targetUri", targetUrlDownload);
        registrationBean.addInitParameter(ProxyServlet.P_LOG, "true");
        return registrationBean;
    }


    @Bean
    @SuppressWarnings(value={"unchecked", "rawtypes"})
    public ServletRegistrationBean proxyServletRegistrationUploading(){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new ProxyServlet(), servletUrlUploading);
        //这里名字必须不一样
        registrationBean.setName("suitUploading");
        registrationBean.addInitParameter("targetUri", targetUrlUploading);
        registrationBean.addInitParameter(ProxyServlet.P_LOG, "true");
        return registrationBean;
    }

}
