nacos2.0.0-2.2.0版本源码运行报错问题解决（Failed to instantiate PersistentClientOperationServiceImpl: Constructor threw exception）

说明

本篇文章是以 2.2.0 进行的，但实际测试 2.0.0 和 2.1.0 也有这个问题，不过 2.2.1 没有，合理猜测在2.0.0-2.2.0都有这个问题。

错误详情

这是具体的报错信息

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'namingHealthController': Unsatisfied dependency expressed through field 'healthOperatorV2'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'healthOperatorV2Impl' defined in file [F:\nacos-2.2.0\naming\target\classes\com\alibaba\nacos\naming\core\HealthOperatorV2Impl.class]: Unsatisfied dependency expressed through constructor parameter 2; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'clientOperationServiceProxy' defined in file [F:\nacos-2.2.0\naming\target\classes\com\alibaba\nacos\naming\core\v2\service\ClientOperationServiceProxy.class]: Unsatisfied dependency expressed through constructor parameter 1; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'persistentClientOperationServiceImpl' defined in file [F:\nacos-2.2.0\naming\target\classes\com\alibaba\nacos\naming\core\v2\service\impl\PersistentClientOperationServiceImpl.class]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.alibaba.nacos.naming.core.v2.service.impl.PersistentClientOperationServiceImpl]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Fail to init node, please see the logs to find the reason.

巡查与解决

根据最后的那条信息，“Caused by: java.lang.IllegalStateException: Fail to init node, please see the logs to find the reason.”，这是说明要看日志，但在项目里有一个 logs 的文件夹，可能会有人会以为是里面的日志，但点击查看就会发现就一个日志文件，打开还是空白的。

那现在该如何进行查找呢？仔细想想，有一些软件喜欢在C盘的用户目录下缓存数据，那 nacos 进行源码运行会不会在这里保存日志，检查一下，发现用户目录下有一个 nacos 目录，点击进去，有一个 logs 文件夹，点击后里面就有日志文件了。

查看了几个日志文件，会发现在alipay-jraft文件中有一个 RocksDBException 的报错。

2023-08-09 09:41:26,267 ERROR Fail to init logStorage

2023-08-09 09:41:26,267 ERROR Node <naming_persistent_service_v2/2.0.0.1:7848> initLogStorage failed.

RocksDBException 的报错，搜索一下 RocksDB，这是一个嵌入式的数据库，可以通过maven运行，功能上有点类似于redis。报错信息是 Failed to create a directory，而且我的用户名是一个中文的，那就可以猜测报错的原因是中文用户名了，实际上也就是这个问题。

那怎么解决呢，总不能修改用户名吧，虽然这也是一种解决办法，但有没有不修改用户名的呢。

相信都能想到修改目录的生成的地址的方法，但是，如何修改目录，通过检查配置文件，虽然有配置日志地址的，但这个明显是 RocksDB 数据库的目录，但可以试试，会发现还是同样的报错，就代表不是这个，那就要进行代码的研究了。

通过 RocksDB，代码中进行全局搜索，发现 nacos 并没有 RocksDB 的配置类，但是在 KvStorage 接口类中的 KvType 枚举中有 RocksDB。

在这里插入图片描述
KvStorage 这个接口类的名字看起来和我上面日志报错里最后的“initLogStorage failed.”有点像，然后 RocksDB 是k-v的数据库，可以进行合理猜测，这里就是进行 RocksDB 操作的其中一个地方。

于是全局查找使用 KvType 的地方，会发现除去测试有两处地方用到的这个地方，分别是 StorageFactory 类和 NamingKvStorage 类。但看一下就明白，NamingKvStorage 是使用方，StorageFactory 是定义方，StorageFactory 定义了 createKvStorage 静态方法，那么只需要对 NamingKvStorage 类进行分析即可。

在这里插入图片描述
NamingKvStorage 类中，使用到 createKvStorage 静态方法的是 NamingKvStorage(final String baseDir) 的构造方法，这里出现了 dir，这是经常用于地址的缩写，就说明快到地方了。

在这里插入图片描述
查看是哪里实体化了这个构造方法，会发现只在抽象方法 BasePersistentServiceProcessor 中的 BasePersistentServiceProcessor() 中使用到了。

在这里插入图片描述
观察里面传递的参数“UtilsAndCommons.DATA_BASE_DIR”，这很明显是个地址，于是找到定义的地方。

在这里插入图片描述
通过日志里面报错的对比”C:\Users\中文的用户名\nacos\data\protocol\raft\naming_persistent_service_v2\log: ϵͳÕҲ»µ½ָ¶“，合理猜测 EnvUtil.getNacosHome() 是定义到用户目录的地方。

那么查看 EnvUtil.getNacosHome() 里面写了啥。

在这里插入图片描述
会发现有个 NACOS_HOME_KEY，查看定义。

在这里插入图片描述
通过全局搜索 nacos.home，发现了 cmd 文件和 sh 文件中有 -Dnacos.home=。

在这里插入图片描述
于是配置了VM参数”-Dnacos.home=F:\nacos-2.2.0\logs\“这个无中文的路径，运行成功。
