nacos2.1集成达梦数据库DM8

1、下载源码

git clone https://github.com/alibaba/nacos.git

2、主pom.xml添加 达梦8的JDBC驱动类库的 声明

    
        
            
                com.dameng
                Dm8JdbcDriver18
                ${dm-connector-java.version}
            
        
    


    
      8.1.1.49
    

3、在 nacos-config 模块pom.xml直接引用驱动库

    com.dameng
    Dm8JdbcDriver18

4、修改nacos-console模块 的配置文件application.properties

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource: 这里打开
spring.datasource.platform=mysql

### Count of DB: 这里打开，并新增 dm.jdbc.driver.DmDriver 的驱动
db.num=1
db.jdbcDriverName=dm.jdbc.driver.DmDriver

### Connect URL of DB: 打开并指定 url 连接字符串
#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.url.0=jdbc:dm://127.0.0.1:5236/IRR_NACOS?STU&zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
db.user.0=IRR_NACOS
db.password.0=xxxxxxxx

5、修改 nacos-config模块下的ExternalDataSourceProperties.java 类

    private String jdbcDriverName;

    public String getJdbcDriverName() {
        return jdbcDriverName;
    }

    public void setJdbcDriverName(String jdbcDriverName) {
        this.jdbcDriverName = jdbcDriverName;
    }

	 List build(Environment environment, Callback callback) {
        List 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));
            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);
            }
            dataSources.add(ds);
            callback.accept(ds);
        }
        Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");
        return dataSources;
    }

6、修改ExternalRolePersistServiceImpl类

备注：搜索全部的表，修改sql语句，在表名前添加模式名

DELETe FROM IRR_NACOS.ROLES WHERe role=?

7、构建项目

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

8、获得构建完成后的工程

distribution/target/nacos-server-$version 下的  nacos 文件夹 就是最终的输出物。

9、启动
