Nacos2.1.2改造适配达梦数据库7.0

出于业务需求，现将Nacos改造适配达梦数据库7.0，记录本次改造过程。

一、前期准备

• Nacos源码，版本：2.1.2：源码下载地址
• 安装达梦数据库7.0：官网下载地址

对于Nacos的认识，可以点击Spring Cloud Alibaba–Nacos服务注册和配置中心查看了解

达梦数据库管理系统是达梦公司推出的具有完全自主知识产权的高性能数据库管理系统（即国产数据库），如图，安装完成，登录即可。

SYSDBA身份登录达梦，执行以下SQL，进行数据库配置：

--创建表空间
CREATE TABLESPACE  "NACOS" DATAFILE 'NACOS.DBF' SIZE 300 autoextend on maxsize 67108863 CACHE = NORMAL;
--创建用户
CREATE USER "NACOS" IDENTIFIED BY "123456789" LIMIT PASSWORD_LOCK_TIME 1, PASSWORD_GRACE_TIME 10 DEFAULT TABLESPACE "NACOS";
--给用户授权
GRANT "RESOURCE","PUBLIC","DBA","VTI" TO "NACOS";

创建NACOS模式下的表结构

二、适配流程

1、项目初始化

IDEA打开源码，该项目是maven工程，配置好maven设置，将依赖成功导入。

2、引入驱动

1、父工程POM文件，properties中添加达梦驱动版本号，使父子工程保持版本一致。

 <dm-connector.version>7.6.0.77</dm-connector.version>

添加依赖：

    <dependency><groupId>com.dameng</groupId><artifactId>Dm7JdbcDriver17</artifactId><version>${dm-connector.version}</version></dependency>

2、修改nacos-config模块、nacos-naming模块的pom文件，增加dm驱动依赖。

        <!-- <dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency>--><dependency><groupId>com.dameng</groupId><artifactId>Dm7JdbcDriver17</artifactId><version>${dm-connector.version}</version></dependency>

3、源码修改

3、修改nacos-console模块的application.properties，增加链接达梦数据库的配置信息

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
spring.datasource.platform=dm### Count of DB:
db.num=1
db.jdbcDriverName=dm.jdbc.driver.DmDriver
### Connect URL of DB:
db.url.0=jdbc:dm://127.0.0.1:5236?scheme=NACOS&useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
db.user.0=NACOS
db.password.0=123456789

4、修改nacos-config模块下的ExternalDataSourceProperties.java

1. 注释Mysql的使用private static final String JDBC_DRIVER_NAME = "com.mysql.cj.jdbc.Driver;。
2. 添加驱动属性private String jdbcDriverName;增加get()、set()方法。
3. DataSourcePoolProperties指定驱动名称poolProperties.setDriverClassName(jdbcDriverName);

5、修改nacos-config模块下PropertiesConstant.java类

修改public static final String DM = "dm";

6、修改nacos-config模块下PropertyUtil.java类

7、修改nacos-core模块下StartingApplicationListener.java类

private static final String DEFAULT_DATABASE = "dm";

8、修改ExternalRolePersistServiceImpl的findRolesLikeRoleName方法：

@Overridepublic List<String> findRolesLikeRoleName(String role) {String sql = "SELECT role FROM roles WHERE role LIKE '%"+role+"%'";List<String> users = this.jt.queryForList(sql, String.class);return users;}

9、修改ExternalUserPersistServiceImpl的findUserLikeUsername方法：

   @Overridepublic List<String> findUserLikeUsername(String username) {String sql = "SELECT username FROM users WHERE username LIKE '%"+username+"%'";List<String> users = this.jt.queryForList(sql, String.class);return users;}

三、启动测试

配置启动类，添加参数-Dnacos.standalone=true，单机模式启动。

浏览器访问：localhost:8848/nacos/，出现登录页面，启动成功。

四、打包测试

修改distribution模块下的application.properties配置文件，配置DM链接信息。

执行以下命令打包：

mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Dcheckstyle.skip=true clean install -U

打包成功后，压缩包在nacos-distribution模块下target目录中，将该包复制到非中文目录下，停止IDEA启动的项目，进入bin目录，双击startup.cmd，启动成功。

浏览器输入localhost:8848/nacos，出现登录页面，启动成功，增加业务配置文件，美好日子开始了。
