问题1：

springboot swagger不支持批量上传文件，批量上传接收的数据是空

问题2：

The valid characters are defined in RFC 7230 and RFC 3986  

根因是tomcat7之后，严格限制了url。

@Component
public class PortalTomcatWebServerCustomizer implements WebServerFactoryCustomizer {


    @Override
    public void customize(WebServerFactory container) {
        TomcatServletWebServerFactory containerFactory = (TomcatServletWebServerFactory) container;
        containerFactory.addConnectorCustomizers(new TomcatConnectorCustomizer() {
            @Override
            public void customize(Connector connector) {
                connector.setProperty("relaxedQueryChars", "[]|-\\:{}^.<>");
                connector.setProperty("relaxedPathChars", "[]|-\\:");
            }
        });
    }
}
