#编者注
因为要编写一个统一的xmlrpc调用与rest，里面涉及到了跨域调用问题。随即有如下内容javascript

#Spring的跨域
##Spring 4.2.x 编者本来是想在Spring响应内容添加跨域请求，但因为很差划定跨域范围，产生了拆分想法。但通过查询Spring文档后发现，最新稳定版本提供了跨域支持**@CrossOrigin**，随即咱们就能够在Controller当中添加注解来完成。css

@Controller
@RequestMapping(value = "/default/Api")
public class XmlrpcServerController {

    @CrossOrigin
    @RequestMapping(method = RequestMethod.POST)
    public Object xmlrpc_api(@RequestBody String body) throws Exception {

        //get body
        System.out.println(body);

        //doing

        return result;
    }

#JSON信息的接收除了咱们要接收上面需求的xml文件之外，rest接收还应当包括其余对象。经过搜索发现须要经过ajax把json以data的形式进行发送。html
