Nacos2.24持久化到Postgres数据库适配

  • 前言
  • 步骤
    • 拉取源码
    • 添加依赖
    • 修改源码
    • 编译打包
    • 修改配置
    • 测试运行
  • 参考

前言

公司基于springboot实现了一套单体框架，目前我负责搭建SpringCloud微服务框架，需要用到nacos，但是由于公司特殊性，nacos的持久化只能选择pg，也上网找了一些资料，这里做一下记录，也把坑给大家踩一下。

步骤

拉取源码

拉取最新源码到本地
官方文档：https://nacos.io/zh-cn/docs/quick-start.html
源码地址：https://github.com/alibaba/nacos develop分支

添加依赖

  • 在项目根下的pom.xml文件中添加如下依赖：
........
<properties>
	<postgresql.version>42.5.1postgresql.version>
properties>

........
<dependency>
    <groupId>org.postgresqlgroupId>
    <artifactId>postgresqlartifactId>
    <version>${postgresql.version}version>
dependency>
  • 在项目的config模块的pom.xml文件中添加如下依赖:
........
<dependency>
   <groupId>org.postgresqlgroupId>
   <artifactId>postgresqlartifactId>
   <version>${postgresql.version}version>
dependency>

修改源码

  • 在项目的plugin模块的datasource模块com.alibaba.nacos.plugin.datasource.impl包下新建一个包名为postgres,拷贝同级包mysql下的所有文件到postgres包下，修改类名和文件名为xxxByPostgreSql，如图

  • 修改刚拷贝的几个类中LIMIT ?,?写法为OFFSET ? LIMIT ?，代码如下，可以直接复制：

修改配置
 
  
修改nacos\conf目录下的application.properties配置，增加如下配置
 
  
spring.datasource.platform=postgresql
db.num=1
db.url.0=jdbc:postgresql://127.0.0.1:5432/nacos_db?currentSchema=public&reWriteBatchedInserts=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
db.user.0=postgres
db.password.0=postgres
# 注意添加配置需要
db.pool.config.driverClassName=org.postgresql.Driver

 
  
修改配置项：
 
  
.....................
### If turn on auth system:
nacos.core.auth.system.type=nacos
nacos.core.auth.enabled=true
.....................
nacos.core.auth.server.identity.key=nacos
nacos.core.auth.server.identity.value=nacos
.....................
nacos.core.auth.plugin.nacos.token.secret.key=VGhpc0lzTXlDdXN0b21TZWNyZXRLZXkwMTIzNDU2Nzg=


 
  
测试运行
 
  
执行命令startup.cmd -m standalone
 【Nacos2.24持久化到Postgres数据库适配——详细版】_第6张图片
 打开地址：http://localhost:8848/nacos，账号密码均输入nacos
 新增一条测试配置
 【Nacos2.24持久化到Postgres数据库适配——详细版】_第7张图片
 打开数据库表config_info
 【Nacos2.24持久化到Postgres数据库适配——详细版】_第8张图片
 
  
完美
 
  
需要注意的是：官方2.2.4版本的是client，对应的server还说2.2.3版本
 
  
参考

    加密社引言在Solidity合约开发过程中，事件（Events）是一种非常重要的机制。它们不仅能够让开发者记录智能合约的重要状态变更，还能够让外部系统（如前端应用）监听这些状态的变化。本文将详细介绍Solidity中的事件机制以及如何利用不同的手段来触发、监听和获取这些事件。事件存储的地方当我们在Solidity合约中使用emit关键字触发事件时，该事件会被记录在区块链的交易收据中。具体而言，事件

    人生的路很长，但是我们只能前进不能后退就像钟表，可以回到起点，却已时过境迁，永远也找不到那个过去的昨天。因我们总是会对过去有着很多留恋不舍和怀念，会时常回头看看走过的脚印，时常想起过去的美好时光，时常想到那些悲伤和不如意。今天的到来时钟不可阻止，历史的记录，原人生最宝贵的不是金钱，不是地位，而是时间。拥有时间就等于拥有一切，因为拥有时间，我们不怕囊中羞涩，因为拥有时间我们不惮创业无门，因为拥有时间

    在上一篇《解读Servlet原理篇一》中提到，要实现javax.servlet.Servlet接口（即写自己的Servlet应用），你可以写一个继承自javax.servlet.GenericServletr的generic Servlet ，也可以写一个继承自java.servlet.http.HttpServlet的HTTP Servlet（这就是为什么我们自定义的Servlet通常是exte

            性能优化是通过某些有效的方法来提高MySQL的运行速度，减少占用的磁盘空间。性能优化包含很多方面，例如优化查询速度，优化更新速度和优化MySQL服务器等。本文介绍方法的主要有： 
        a.优化查询 
        b.优化数据库结构

    项目需要当某事件触发时，执行http请求任务，失败时需要有重试机制，并根据失败次数的增加，重试间隔也相应增加，任务可能并发。 
由于是耗时任务，首先考虑的就是用线程来实现，并且为了节约资源，因而选择线程池。 
为了解决不定间隔的重试，选择Timer和TimerTask来完成

    首先要说的是，不同版本数据库提供的系统表会有不同，你可以根据数据字典查看该版本数据库所提供的表。 
 
select * from dict where table_name like '%SESSION%'; 
就可以查出一些表，然后根据这些表就可以获得会话信息

    类的继承可以提高代码的重用行，减少冗余代码；还能提高代码的扩展性。Java继承的关键字是extends 
格式:public class 类名（子类）extends 类名（父类）{ } 
子类可以继承到父类所有的属性和普通方法，但不能继承构造方法。且子类可以直接使用父类的public和 
protected属性，但要使用private属性仍需通过调用。 
子类的方法可以重写，但必须和父类的返回值类

线程同步异步
                                    
    多线程和同步 : 如进程、线程同步，可理解为进程或线程A和B一块配合，A执行到一定程度时要依靠B的某个结果，于是停下来，示意B运行；B依言执行，再将结果给A；A再继续操作。  所谓同步，就是在发出一个功能调用时，在没有得到结果之前，该调用就不返回，同时其它线程也不能调用这个方法  
  
多线程和异步:多线程可以做不同的事情,涉及到线程通知

            在JSP的开发过程中，经常出现中文乱码的问题。 
        首先了解一下Java中文问题的由来： 
        Java的内核和class文件是基于unicode的，这使Java程序具有良好的跨平台性，但也带来了一些中文乱码问题的麻烦。原因主要有两方面，
