Nacos适配达梦数据库
Nacos提供了两种存储方式文件存储、mysql存储，默认使用的是文件存储的方式，在实际开发中我们可能需要使用其它数据库，比如达梦、人大金仓等，就需要我们自己对Nacos源码进行修改适配，本文以达梦数据库展开，教你如何进行源码修改。
前期准备
首先我们需要Nacos源码，可以去github-nacos或者gitee-nacos进行下载，
本文以2.1.2版本为例，其它版本类似，稍有不同之处请参考其他博主教程。
修改流程
初始化项目
引入达梦数据库驱动；
修改父工程pom文件，引入版本号
<dm-connector-java.version>8.1.1.193</dm-connector-java.version>
1
修改三个地方的pom文件依赖（父工程、nacos-config、nacos-naming）注释mysql驱动，添加达梦数据库驱动
子模块版本号可以不写
<!-- <dependency>-->
<!-- <groupId>mysql</groupId>-->
<!-- <artifactId>mysql-connector-java</artifactId>-->
<!-- <version>${mysql-connector-java.version}</version>-->
<!-- </dependency>-->
<dependency>
<groupId>com.dameng</groupId>
<artifactId>Dm8JdbcDriver18</artifactId>
<version>${dm-connector-java.version}</version>
</dependency>
修改达梦数据库连接参数配置文件nacos-console模块的application.properties
达梦数据库sql如下

修改nacos-config模块下的ExternalDataSourceProperties.java
注释掉private static final String JDBC_DRIVER_NAME = "com.mysql.cj.jdbc.Driver";。
添加驱动属性private String jdbcDriverName;，生成了get、set方法。
为DataSourcePoolProperties指定驱动名称poolProperties.setDriverClassName(jdbcDriverName);
全部代码如下：
public class ExternalDataSourceProperties {
// private static final String JDBC_DRIVER_NAME = "com.mysql.cj.jdbc.Driver";
private String jdbcDriverName;
private static final String TEST_QUERY = "SELECT 1";
private Integer num;
private List<String> url = new ArrayList<>();
private List<String> user = new ArrayList<>();
private List<String> password = new ArrayList<>();
public void setNum(Integer num) {
this.num = num;
}
public void setUrl(List<String> url) {
this.url = url;
}
public void setUser(List<String> user) {
this.user = user;
}
public void setPassword(List<String> password) {
this.password = password;
}
public String getJdbcDriverName() {
return jdbcDriverName;
}
public void setJdbcDriverName(String jdbcDriverName) {
this.jdbcDriverName = jdbcDriverName;
}
/**

*

poolProperties.setPassword(getOrDefault(password, index, password.get(0)).trim());

修改nacos-config模块下PropertiesConstant.java类
修改public static final String MYSQL= "mysql";为public static final String DM = "dm";
修改nacos-config模块下PropertyUtil.java类
setUseExternalDB(PropertiesConstant.DM
.equalsIgnoreCase(getString(PropertiesConstant.SPRING_DATASOURCE_PLATFORM, "")));
修改nacos-core模块下StartingApplicationListener.java类
private static final String DEFAULT_DATABASE = "dm";
启动测试
启动主类加入-Dnacos.standalone=true参数，以单机模式启动
如果出现use external storage说明你全部配置正确，如果没有，请仔细检查操作步骤。
测试新增数据
语法适配
测试发现：角色管理-绑定角色-动态查询用户名、权限管理-添加权限-动态查询角色名接口sql报错
修改下列类中sql语句
ExternalRolePersistServiceImpl
@Override
public 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;
}
ExternalUserPersistServiceImpl
@Override
public 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;
}
修改后测试结果如下，可以动态匹配成功。
源码打包
打包前一定要修改distribution模块下的application.properties文件，与console模块配置一样一样。这个配置就是打包完成后的配置文件。
打包项目，跳过test、pmd、checkstyle
mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Dcheckstyle.skip=true clean install -U
1
打包成功后，压缩包在nacos-distribution模块下target目录中
踩坑
可能会出现的错误，找不到Dm8JdbcDriver18jar包，原因是需要我们手动将Dm8JdbcDriver18添加到我们的本地maven库中，可以使用如下命令进行添加
mvn install:install-file -Dfile=D:\***\dm\drivers\jdbc\DmJdbcDriver18.jar -DgroupId=com.dameng -DartifactId=Dm8JdbcDriver18 -Dversion=8.1.1.193 -Dpackaging=jar
1
file后面改成自己的达梦安装目录下的驱动jar包，groupId、artifactId、version请与pom中引入内容保持一致
No DataSource set
一般是数据库连接配置文件出错或者是dm数据库表有问题，请从配置文件中数据库名，ip、账号、密码开始排查，然后排查dm数据库表及数据是否正确创建。
注： 修改完成后直接通过下述命令进行编译，在distribution模块的target目录生成编译文件
mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Dcheckstyle.skip=true clean install -U
