本文介绍了一个使用Hessian进行服务端调用的例子，展示了如何通过Spring配置文件及编程方式实现远程服务调用。文章包括了具体的配置示例和服务调用代码。

spring-hessian-client.xml是hessian客户端调用的配置,可以配置多个.服务端的配置参考spring-hessian-server.xml

很多时候，服务端地址是变得，那么我们就不能总变spring-hessian-client.xml吧，除非你用disconf来管理配置文件，但是那为啥又不直接使用dubbo呢？除了配置的方式，另外一种方式，就可以写代码调用，下面是实例

@Transactional(readOnly = false)
    @Override
    public void sync() {
        List<FontalInstock> fontalInstocks = fontalInstockService.selectNoSyncDatas();
        if (!CheckEmptyUtil.isEmpty(fontalInstocks)){
            String datas = gson.toJson(fontalInstocks);
            String merchCode = fontalConfigService.getMerchCode();
            String url = fontalConfigService.getMonitorUrl() + WorkerEnum.syncMonitorInstock.value();
            String upDown = fontalConfigService.getUpDown();
            //
            HessianProxyFactory factory  = new HessianProxyFactory();
            SyncMonitorInstockService syncMonitorInstockService;
            String result = null;
            try {
                syncMonitorInstockService = (SyncMonitorInstockService)factory.create(SyncMonitorInstockService.class,url);
                result = syncMonitorInstockService.sync(datas, merchCode, upDown);
                if (!CheckEmptyUtil.isEmpty(result)){
                    // 更改上传结果
                    callback(result);
                }
            } catch (MalformedURLException e) {
                logger.error("远程调用monitor 失败,失败原因:{}",e.getMessage());
                e.printStackTrace();
            }
        }
    }
