这是我的restFull web服务
public File[] restore(String test){
File[] files = new File(System.getProperty("user.dir")+"/BackUpsMapping").listFiles();
System.out.println("done");
return files;
}
下面是使用web服务的代码部分
ResponseEntity<File[]> results = restTemplate.getForEntity("http://localhost:8181/cxf/karafsimple/say/restore", File[].class);
谢谢你的帮助
