### 配置代理
#请求resource时代理转发到端口8088项目中
proxy.test.servlet_url_one= /resource/*
proxy.test.target_url_one= https://localhost:8088

@Component
@Data
public class ProxyFilterServlet {
 @Value("${proxy.test.target_url_one}")
 private String targetUrl;
 @Value("${proxy.test.servlet_url_one}")
 private String servletUrl;
}

@Configuration
public class ProxyServletConfig {
 @Autowired
 private ProxyFilterServlet proxyFilterServlet;
 //多个代理servlet可以配置多个bean
 @Bean
 public ServletRegistrationBean servletRegistrationBean(){
 ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new ProxyServlet(), proxyFilterServlet.getServletUrl());
 //这个setName必须要设置，并且多个的时候，名字需要不一样
 servletRegistrationBean.setName("go_backend");
 servletRegistrationBean.addInitParameter("targetUri", proxyFilterServlet.getTargetUrl());
 servletRegistrationBean.addInitParameter(ProxyServlet.P_LOG, "false");
 return servletRegistrationBean;
 }
