1.在父工程pom.xml添加依賴：
<dependency><groupId>com.dameng</groupId><artifactId>DmJdbcDriver18</artifactId><version>8.1.1.193</version>
</dependency>2.在nacos-config模塊pom.xml添加依賴：
<dependency><groupId>com.dameng</groupId><artifactId>DmJdbcDriver18</artifactId><version>8.1.1.193</version>
</dependency>3.修改nacos-console模塊配置文件application.properties?:
spring.sql.init.platform=dm
### Count of DB:
db.num=1### Connect URL of DB:
# db.url.0=jdbc:mysql://127.0.0.1:3306/nacos?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
# db.user=nacos
# db.password=nacos
db.jdbcDriverName=dm.jdbc.driver.DmDriver
db.url.0=jdbc:dm://localhost:5236?schema=NACOS
db.user.0=SYSDBA
db.password.0=SYSDBA4. 全局搜索這個ExternalDataSourceProperties.java類，添加如下信息：
//添加變量private String jdbcDriverName;public String getJdbcDriverName() {return jdbcDriverName;}public void setJdbcDriverName(String jdbcDriverName) {this.jdbcDriverName = jdbcDriverName;}//替換原來的方法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);if (StringUtils.isEmpty(poolProperties.getDataSource().getDriverClassName())) {System.out.println("jdbcDriverName=" + jdbcDriverName);if (StringUtils.isNotEmpty(jdbcDriverName)) {poolProperties.setDriverClassName(jdbcDriverName);} else {poolProperties.setDriverClassName(JDBC_DRIVER_NAME);}System.out.println("dataSources=" + dataSources);}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();if (StringUtils.isEmpty(ds.getConnectionTestQuery())) {ds.setConnectionTestQuery(TEST_QUERY);}dataSources.add(ds);callback.accept(ds);}Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");return dataSources;}
5.?修改DataSourceConstant.java類，添加變量：
public static final String DM = "dm";
6.修改ExternalConfigInfoPersistServiceImpl.java這個類的176和194行異常DuplicateKeyException改成DataIntegrityViolationException?
7.nacos-datasource-plugin模塊添加dm實現類，復制一個mysql包，然后把所有類名換成Dm，再把里面所有跟mysql相關的變量換成dm,如下：
同時把對應resources目錄下的文件，添加如下內容：
8.在根目錄運行：
mvn -Prelease-nacos -Dmaven.test.skip=true -Dcheckstyle.skip=true -Dcheckstyle.skip=true clean install -U9.在nacos-distribution模塊下會有生成的jar包，然后可以正常使用訪問了。。。
