Nacos 2.5.0 深度适配PostgreSQL全流程

06-01 1685阅读

1.依赖配置阶段

在项目根目录(nacos-all)的pom.xml中引入PostgreSQL驱动依赖

为nacos-config-plugin和nacos-persistence模块添加PostgreSQL相关依赖

2.数据源适配改造

修改nacos-datasource-plugin模块下的DataSourceConstant常量类，新增PostgreSQL相关常量

在impl目录下新建postgresql包，基于MySQL实现类复制改造：

重命名类后缀为Postgresql
调整SQL分页语法为PostgreSQL特有的OFFSET ? LIMIT ?格式

将where.limit方法改造为where.limitPG

3.持久层配置优化

在nacos-datasource-plugin模块下的resource/mapper目录下新增PostgreSQL专属的Mapper文件

com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoBetaMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoTagMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoGrayMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigTagsRelationMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.HistoryConfigInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.TenantInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.TenantCapacityMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.GroupCapacityMapperByPostgresql

nacos-persistence模块下修改PersistenceConstant类补充PostgreSQL支持

nacos-persistence模块下重构ExternalDataSourceProperties类：
新增driverName属性及setter方法

将静态的JDBC_DRIVER_NAME改为动态获取驱动名称

4.分页处理适配

在default-auth-plugin模块中：

扩展AuthPageConstant分页常量
新增PostgresqlPageHandlerAdapter（基于MySQL适配器改造）

在PageHandlerAdapterFactory中注册PostgreSQL处理器

5.打包

mvn clean -Prelease-nacos install -U -DskipTests -Drat.skip=true

打包成功后在distribution下可以找到打包好的文件

配置application.properties：

替换为实际的PostgreSQL连接信息
特别注意schema名称配置

调整start.cmd启动脚本参数

spring.datasource.platform=postgresql
db.num=1
db.url.0=jdbc:postgresql://localhost:54321/mydb?currentSchema=public&reWriteBatchedInserts=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
db.user.0=user
db.password.0=password
db.pool.config.driverClassName=org.postgresql.Driver

最后附赠PG建表语句，祝大家都成功！！！
