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

  1. 初始化项目
  2. 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>
  • 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>
  1. 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

INSERT INTO nacos.roles (username, role) VALUES ('nacos', 'ROLE_ADMIN'); commit;
  1. 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;}/** * Build serveral HikariDataSource. * * @param environment {@link Environment} * @param callbackCallback function when constructing data source * @return List of {@link HikariDataSource} */List<HikariDataSource> build(Environment environment, Callback<HikariDataSource> callback) {List<HikariDataSource> dataSources = new ArrayList<>();Binder.get(environment).bind("db", Bindable.ofInstance(this));Preconditions.checkArgument(Objects.nonNull(num), "db.num is null");Preconditions.checkArgument(CollectionUtils.isNotEmpty(user), "db.user or db.user.[index] is null");Preconditions.checkArgument(CollectionUtils.isNotEmpty(password), "db.password or db.password.[index] is null");for (int index = 0; index < num; index++) {int currentSize = index + 1;Preconditions.checkArgument(url.size() >= currentSize, "db.url.%s is null", index);DataSourcePoolProperties poolProperties = DataSourcePoolProperties.build(environment);poolProperties.setDriverClassName(jdbcDriverName);poolProperties.setJdbcUrl(url.get(index).trim());poolProperties.setUsername(getOrDefault(user, index, user.get(0)).trim());poolProperties.setPassword(getOrDefault(password, index, password.get(0)).trim());HikariDataSource ds = poolProperties.getDataSource();ds.setConnectionTestQuery(TEST_QUERY);dataSources.add(ds);callback.accept(ds);}Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");return dataSources;}interface Callback<D> {/** * Perform custom logic. * * @param datasource dataSource. */void accept(D datasource);}}

  1. 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";

  2. 修改nacos-config模块下PropertyUtil.java类

setUseExternalDB(PropertiesConstant.DM.equalsIgnoreCase(getString(PropertiesConstant.SPRING_DATASOURCE_PLATFORM, "")));

  1. 修改nacos-core模块下StartingApplicationListener.java类
    private static final String DEFAULT_DATABASE = "dm";

启动测试

  1. 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。

访问http://localhost:8848/nacos
测试新增数据

语法适配

  1. 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
@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;}

  • ExternalUserPersistServiceImpl
 @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;}

  • 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。

    1. 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

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

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。
