坑！！！sofarpc+zookeeper整合的坑
前言
sofarpc是目前在着手使用的一个rpc框架，然鹅，一直整合不成功，现在提取出一个简单工程来排错。注意，使用的sofarpc的版本是5.5.0。
坑1-中文路径的错
有中文路径的话会提示下面类似的错误：
log4j:ERROR Could not parse url 巴拉巴拉巴拉巴拉com.sun.org.apache.xerces.internal.util.URI$MalformedURIException: Path contains invalid character: 巴拉巴拉巴拉巴拉
因为sofarpc会读取自己jar包里面的一个log-conf.xml文件，初始化log4j，不过log4j压根不认中文路径，都会报错的。所以，项目目录不要有中文，也不要有特殊字符，或者空格，这是最省事的做法。
坑2–无法注册注册服务到zookeeper
这个问题有点大了，各种各样的原因都有的，下面我就说说自己的一个例子以作参考。
项目代码
新建一个项目，如下：
我都是直接抄网上的，还有抄官网的例子，下面是各个java文件：
package net.hello.rpc;
public interface HelloService {
public String sayHello(String name);
}
package net.hello.rpc;
public class HelloServiceImpl implements HelloService {
public String sayHello(String name) {
return "hello " + name;
}
}
package net.hello.main;
import com.alipay.sofa.rpc.config.ProviderConfig;
import com.alipay.sofa.rpc.config.RegistryConfig;
import com.alipay.sofa.rpc.config.ServerConfig;
import com.alipay.sofa.rpc.context.RpcRuntimeContext;
import com.alipay.sofa.rpc.log.Logger;
import com.alipay.sofa.rpc.log.LoggerFactory;
import net.hello.rpc.HelloService;
import net.hello.rpc.HelloServiceImpl;
/**

*/
public class ZookeeperBoltServerMain {
/**
* slf4j Logger for this class
*/
private final static Logger LOGGER = LoggerFactory.getLogger(ZookeeperBoltServerMain.class);
public static void main(String[] args) {
/**
* 运行需要pom.xml里增加依赖
org.apache.curator
curator-recipes
test
*/
RegistryConfig registryConfig = new RegistryConfig()
.setProtocol("zookeeper")
.setAddress("127.0.0.1:2181");
ServerConfig serverConfig = new ServerConfig()
.setPort(22101)
.setDaemon(false);
ProviderConfig providerConfig = new ProviderConfig()
.setInterfaceId(HelloService.class.getName())
.setRef(new HelloServiceImpl())
.setServer(serverConfig)
.setRegistry(registryConfig);
providerConfig.export();
LOGGER.warn("started at pid {}", RpcRuntimeContext.PID);
}
}
package net.hello.main;
import com.alipay.sofa.rpc.config.ConsumerConfig;
import com.alipay.sofa.rpc.config.RegistryConfig;
import com.alipay.sofa.rpc.context.RpcRuntimeContext;
import com.alipay.sofa.rpc.log.Logger;
import com.alipay.sofa.rpc.log.LoggerFactory;
import net.hello.rpc.HelloService;
/**

*
*
* @author GengZhang
*/
public class ZookeeperBoltClientMain {
/**
* slf4j Logger for this class
*/
private final static Logger LOGGER = LoggerFactory.getLogger(ZookeeperBoltClientMain.class);
public static void main(String[] args) throws InterruptedException {
/**

org.apache.curator
curator-recipes
test
*/
RegistryConfig registryConfig = new RegistryConfig()
.setProtocol("zookeeper")
.setAddress("127.0.0.1:2181");
ConsumerConfig consumerConfig = new ConsumerConfig()
.setInterfaceId(HelloService.class.getName())
.setRegistry(registryConfig)
.setTimeout(3000);
HelloService helloService = consumerConfig.refer();
LOGGER.warn("started at pid {}", RpcRuntimeContext.PID);
try {
while (true) {
try {
String s = helloService.sayHello("xxx");
LOGGER.warn("{}", s);
} catch (Exception e) {
LOGGER.error(e.getMessage(), e);
}
try {
Thread.sleep(2000);
} catch (Exception e) {
}
}
} catch (Exception e) {
LOGGER.error("", e);
}
synchronized (ZookeeperBoltClientMain.class) {
while (true) {
ZookeeperBoltClientMain.class.wait();
}
}
}
}
注意，这个项目是gradle项目，gradle文件如下：
plugins {
id 'java'
}
group 'net.w2p'
version '1.0-SNAPSHOT'
/***定义项目环境变量***/
String _ENV_="test" //默认是测试环境

println "!!!您自定义的环境无效！环境变量只能在test、ppe、product中三选一！！";
}
else{

解释一下，sofarpc用的版本是5.5.0，而zk客户端用的版本是：
4.1.0
排错
运行zookeeperBoltServerMain：
没有任何报错。。额，估计是发布任务成功了。美滋滋，下面用命令行连接zk，看看zk的节点有没有添加到：
用zk做注册中心最后都是要往里面插入节点的，没有插入的话就表示连接不上或者压根没注册服务，简单的命令用法请看：
ZooKeeper系列3：ZooKeeper命令、命令行工具及简单操作
下面直接操作。
心凉了半截。。。节点只有zookeeper。。这个估计不会是sofarpc添加的。。。也就是sofarpc没有添加节点。
执行客户端：
一直卡住，死也不说什么错。。停止了也没报错。。。麻烦了。。
不停尝试，不过，在偶然情况下看到了日志记录的痕迹：
这家伙原来都不输出错误，将错误全部都放到账号下面的logs文件夹里面！！！
一查：
果然有。。。。然后逐个逐个打开文件看看，欸，发现问题了：

意思是curator里面没有需要的方法—额，估计是版本冲突了，我引入的curator是最新的。。。sofarpc不支持最新的！
赶紧查一查官方demo使用的curator的版本号：
没有给出curator版本号啊。。。。难怪我会找最新的了，因为没给出来。。。
查找缺失的方法，可以看到有同仁用过这方法了：
Zookeeper客户端Curator使用详解
而且还给出版本引用：
用的是2.12.0，查查官网，这个版本是不是很旧了：
欸？？？这些版本号都不是版本越大时间越新的，看来误解了，各个大版本应该是对应不同的端的。。
版本2一直迭代，最新的是2.13.0，好了，改改：
好了，再运行server：
zk上用命令查看节点：
好了，稳妥了，已经注册到zk上面了。
开client：
突然发现自己没有写输出语句，下面补充一下：
结果：
好了，已经可以运行了。不过，有点bug还要跟进，因为日志又有错了：
这次是fastjson错误：

也是醉了。。。
it同仁也遇到过：
好了，查了maven最新版本为2.9.8，下面在build.gradle上面添加依赖：
就是说，最后的build.gradle如下：
plugins {

}

version '1.0-SNAPSHOT'
/***定义项目环境变量***/
String _ENV_="test" //默认是测试环境
if(System.getProperty("env")!=null&&!System.getProperty("env").isEmpty()){

if(!tmpEnv.equals("test")
&&!tmpEnv.equals("ppe")
&&!tmpEnv.equals("product")){
println "!!!您自定义的环境无效！环境变量只能在test、ppe、product中三选一！！";
}
else{
_ENV_=tmpEnv;
}
}
println "当前指定环境为：$_ENV_"
/***定义项目环境变量 end***/
/***rootProject配置 开始***/
/***这个配置中心是需要手工配置的。***/

结语
想不到一些小小的整合都要话费这么多心思。。
网上那么多资料这么多例子都检查过没出过问题吗？
