nacos2.1集成达梦数据库

1、下载源码

https://github.com/alibaba/nacos

2、新增达梦驱动依赖

父pom.xml

<dm-driver.version>8.1</dm-driver.version>

        <dependency>
            <groupId>com.dm.driver</groupId>
            <artifactId>jdbc18</artifactId>
            <version>${dm-driver.version}</version>
        </dependency>
           

nacos-config模块pom.xml

<dependency>
            <groupId>com.dm.driver</groupId>
            <artifactId>jdbc18</artifactId>
        </dependency>
           

3、修改nacos-console模块配置文件application.properties

#*************** Config Module Related Configurations ***************#
### If use MySQL as datasource:
spring.datasource.platform=dm
### Count of DB:
db.num=1

### Connect URL of DB:
db.jdbcDriverName=dm.jdbc.driver.DmDriver
db.url.0=jdbc:dm://127.0.0.1:5236/MAIN?STU&zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
db.user.0=NACOS
db.password.0=NACOS!@#
           

4、 nacos-config模块修改java类

修改ExternalDataSourceProperties.java

private String jdbcDriverName;

    public String getJdbcDriverName() {
        return jdbcDriverName;
    }

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

	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));
            System.out.println("===================================");
            System.out.println("jdbcDriverName=" + jdbcDriverName);
            if (StringUtils.isNotEmpty(jdbcDriverName)) {
                // 怎加其他数据库驱动
                ds.setDriverClassName(jdbcDriverName);
            } else {
                //默认为mysql驱动
                ds.setDriverClassName(JDBC_DRIVER_NAME);
            }
            System.out.println("===================================");
            System.out.println("dataSources=" + dataSources);
            dataSources.add(ds);
            callback.accept(ds);
        }
        Preconditions.checkArgument(CollectionUtils.isNotEmpty(dataSources), "no datasource available");
        return dataSources;
    }
           

修改PropertiesConstant.java

//新增达梦常量
    public static final String DM = "dm";
           

修改PropertyUtil.java

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

代码后面增加以下代码

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

5、运行

idea运行单机版需要添加VM options配置：-Dnacos.standalone=true，直接springboot run就可以，打包部署到服务器经历的一些问题：

网上说打出来的包在nacos-distribution/target/目录下有nacos-server-2.1.1.tar.gz文件，一开始用idea打包死活打不出来，在nacos-console/target下有nacos-server.jar，用这个jar运行单机又出现异常：java.net.UnknownHostException: jmenv.tbsite.net，nacos默认是集群部署的，单机启动需要添加参数用-m standalone，用start.sh启动命令：./startup.sh -m standalone 用jar启动命令：java ‘-Dnacos.standalone=true’ -jar ./nacos-server.jar；最后配了maven环境变量，用命令：mvn -Prelease-nacos ‘-Dmaven.test.skip=true’ ‘-Dcheckstyle.skip=true’ clean install -U 在nacos-distribution/target/目录下有nacos-server-2.1.1.tar.gz文件
