### nacos2.1.1 更改dm 达梦数据库 ###

### 1. 下载源码 ###

[源码地址：https://github.com/alibaba/nacos/tree/2.1.1][https_github.com_alibaba_nacos_tree_2.1.1]

### 2. 在根目录下面的pom下，增加dm的驱动 ###

<properties>
           <dm-connector-java.version>8.1.1.49</dm-connector-java.version>
        </properties>
        
              <dependency>
                    <groupId>com.dameng</groupId>
                    <artifactId>Dm8JdbcDriver18</artifactId>
                    <version>${
        dm-connector-java.version}</version>
                </dependency>

### 3. 在 nacos-config 模块pom.xml直接引用驱动库 ###

<dependency>
                <groupId>com.dameng</groupId>
                <artifactId>Dm8JdbcDriver18</artifactId>
            </dependency>

### 4. 修改数据库配置文件对应的java文件ExternalDataSourceProperties.java ###

//增加属性
      private String jdbcDriverName;
    
        public String getJdbcDriverName() {
        
            return jdbcDriverName;
        }
    
        public void setJdbcDriverName(String jdbcDriverName) {
        
            this.jdbcDriverName = jdbcDriverName;
        }
    
       //修改方法
       /**
         * Build serveral HikariDataSource.
         *
         * @param environment {@link Environment}
         * @param callback    Callback 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(JDBC_DRIVER_NAME);
                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);
                ds.setIdleTimeout(TimeUnit.MINUTES.toMillis(10L));
                ds.setConnectionTimeout(TimeUnit.SECONDS.toMillis(3L));
                //此处修改start
                if (StringUtils.isNotEmpty(jdbcDriverName)) {
        
                    // 增加其他数据库驱动的支持
                    ds.setDriverClassName(jdbcDriverName);
                } else {
        
                    //默认使用mysql驱动
                    ds.setDriverClassName(JDBC_DRIVER_NAME);
                }
                //此处修改end
                dataSources.add(ds);
                callback.accept(ds);
            }
            Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");
            return dataSources;
        }

### 5. 构建项目 ###

`mvn -Prelease-nacos -Dmaven.test.skip=true -Dpmd.skip=true -Dcheckstyle.skip=true clean install -U`![在这里插入图片描述][e22f50ada3404a72856191ddd9786863.png]  
![在这里插入图片描述][39d4d77654ae4ed5ad82bb64dfb8a6a8.png]

### 6. 打包后的文件路径 ###

E:\ideaWorkspace\nacos-2.2.0\distribution|distribution\target\nacos-server-$version 下的  nacos 文件夹 就是最终的输出物。

### 7. 启动(启动路径不能有中文路径，中文路径下会报错) ###

start startup.cmd -m standalone

### 8. 以打好的nacos资源 ###

[nacos2.1.1-dm-linux版本][nacos2.1.1-dm-linux]  
[nacos2.1.1-dm-windows版本][nacos2.1.1-dm-windows]  
[nacos2.1.1-dm-sql][]

### 9. 访问路径 ###

### 10. 打包的时候可能出现 nacos-istio 包 打包失败的问题： ###

解决方式，把打包插件修改下面的即可解决
