dubbox rest服务接受参数乱码

dubbo服务接口如下 @Path("addcustomer") public interface IncrCustomerInterface { @POST @Path("saveenter") @Consumes @Produces public String saveEnterpriseInfo(@BeanParam EnterpriseInfo enterpriseInfo,@BeanParam CustomerBean custBean); 调用方代码如下 @RestController @RequestMapping("/bankCustomer") public class BankCustomerController { @Autowired private DubboSupport dubboSupport; @RequestMapping("/testSingle") public void testSingle() throws Exception { EnterpriseInfo enterpriseInfo = new EnterpriseInfo(); enterpriseInfo.setName(new String("测试企业名称".getBytes("ISO-8859-1"), "gbk")); enterpriseInfo.setCustomerNo("000001111"); enterpriseInfo.setIdCardType(new String("二代身份证".getBytes("ISO-8859-1"), "UTF-8")); enterpriseInfo.setAddress(new String("测试企业地址".getBytes("ISO-8859-1"), "gb2312")); enterpriseInfo.setIdentityAddress("测试企业身份证地址"); enterpriseInfo.setIdentityNo("测试企业身份证号码110"); IncrCustomerInterface incrCustomerInterface = dubboSupport.getIncrCustomerInterface(); CustomerBean bean = new CustomerBean(); bean.setCustomerNo("11111"); incrCustomerInterface.saveEnterpriseInfo(enterpriseInfo,bean); } } 服务端接口接受到参数以后,里面的中文全部为乱码,怎么解决?

关于dubbo和dubbox的问题,希望得到您的回答。

我在项目里面引入的依赖是 ![图片说明](https://img-ask.csdn.net/upload/201905/08/1557279772_960548.png) 我想知道这是dubbo还是dubbox,dubbo是Apache的项目,dubbox是当当的项目,那这里的阿里的依赖,是dubbo还是dubbox?这是第一个问题。 第二个问题:执行这个过程的目的是什么? ![图片说明](https://img-ask.csdn.net/upload/201905/08/1557279985_54050.png)

zookeeper rest dubbox

zookeeper里只存了dubbox rest服务的类名 方法名 我要怎样拿到资源地址,怎样调用

maven聚合ssm框架启动Tomcat不报错

ssm 用maven做的聚合项目为啥编译不了controller,进入不了jsp(除了index)

springboot 整合dubbox,采用外部应用服务器的servlet容器配置问题

<dubbo:protocol name="rest" server="servlet"/>在使用该配置使用外部容器时,官方说明: 如果你是用spring的ContextLoaderListener来加载spring,则必须保证BootstrapListener配置在ContextLoaderListener之前,否则dubbo初始化会出错。 是否有大神能够指导如何实现这个配置保证BootstrapListener在ContextLoaderListener之前完成配置?

dubbox 遇到的kryo序列化问题,搞了2天未果

我先把错误贴出来吧 ![这是控制台报错日志](https://img-ask.csdn.net/upload/201710/15/1508066124_663506.png) 我的序列化是这样配置的 ![图片说明](https://img-ask.csdn.net/upload/201710/15/1508066158_80452.png) user用户管理依赖这个通用接口包, web项目也依赖这个通用接口包,然后都会调用这个序列化的实现,web上可以请求到user里面,但是返回的时候就报序列化错误了。搞了2天了。哪位好心人帮忙看一下吧

dubbo中rest服务注册到zookeeper如何通过zookeeper访问呢?

dubbo发布rest服务,并注册到zookeeper,但是访问地址还是服务器的地址,并没有通过zookeeper,那么zookeeper好像没有什么用了?如果只发布rest服务

最近碰到dubbox 里面添加filter的问题,网上找了下,也没有啥效果,想问问有谁也碰到过?
