【全栈开发指南】GitEgg-Cloud开启分库分表配置

  因为在实际业务应用中，大部分的业务需求达不到分库分表的级别，有的业务稍微复杂点可能分库就可以搞定，不需要分表，所以这里注释关闭掉了shardingsphere-jdbc分库分表和Seata分布式事务的配置，只保留了dynamic-datasource动态多数据源的配置，如果需要使用分表和分布式事务，那么把注释打开即可。
1、打开gitegg-platform-db中shardingsphere-jdbc的依赖注释

        <!-- Sharding-Jdbc -->
        <dependency>
            <groupId>org.apache.shardingsphere</groupId>
            <artifactId>shardingsphere-jdbc-core-spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.shardingsphere</groupId>
            <artifactId>shardingsphere-jdbc-core-spring-namespace</artifactId>
        </dependency>

2、打开gitegg-platform-db中DynamicDataSourceProviderConfig.java的配置注释

@Configuration
@AutoConfigureBefore(DynamicDataSourceAutoConfiguration.class)
public class DynamicDataSourceProviderConfig {

    @Resource
    private DynamicDataSourceProperties properties;

    /**
     * shardingSphereDataSource
     */
    @Lazy
    @Resource(name = "shardingSphereDataSource")
    private DataSource shardingSphereDataSource;

    @Bean
    public DynamicDataSourceProvider dynamicDataSourceProvider() {
        Map<String, DataSourceProperty> datasourceMap = properties.getDatasource();
        return new AbstractDataSourceProvider() {
            @Override
            public Map<String, DataSource> loadDataSources() {
                Map<String, DataSource> dataSourceMap = createDataSourceMap(datasourceMap);
                dataSourceMap.put("sharding", shardingSphereDataSource);
                return dataSourceMap;
            }
        };
    }

    /**
     * 将动态数据源设置为首选的
     * 当spring存在多个数据源时, 自动注入的是首选的对象
     * 设置为主要的数据源之后，就可以支持shardingjdbc原生的配置方式了
     */
    @Primary
    @Bean
    public DataSource dataSource(DynamicDataSourceProvider dynamicDataSourceProvider) {
        DynamicRoutingDataSource dataSource = new DynamicRoutingDataSource();
        dataSource.setPrimary(properties.getPrimary());
        dataSource.setStrict(properties.getStrict());
        dataSource.setStrategy(properties.getStrategy());
        dataSource.setProvider(dynamicDataSourceProvider);
        dataSource.setP6spy(properties.getP6spy());
        dataSource.setSeata(properties.getSeata());
        return dataSource;
    }
}

3、修改配置文件shardingsphere-jdbc的分库分表规则

  # shardingsphere 配置
  shardingsphere:
    props:
      sql:
        show: true
    datasource:
      common:
        type: com.alibaba.druid.pool.DruidDataSource
        validationQuery: SELECT 1 FROM DUAL        
      names: shardingorder0,shardingorder1
      shardingorder0:
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://127.0.0.1/gitegg_cloud_mall_order0?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf8&all owMultiQueries=true&serverTimezone=Asia/Shanghai
        username: root
        password: root
      shardingorder1:
        type: com.alibaba.druid.pool.DruidDataSource
        url: jdbc:mysql://127.0.0.1/gitegg_cloud_mall_order1?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf8&all owMultiQueries=true&serverTimezone=Asia/Shanghai
        username: root
        password: root
    rules:
      sharding:
        tables:
          t_mall_order:
            actual-data-nodes: shardingorder$->{0..1}.t_mall_order$->{0..1}
            # 配置分库策略
            databaseStrategy:
              standard:
                shardingColumn: id
                shardingAlgorithmName: database-inline
            table-strategy:
              standard:
                sharding-column: id
                sharding-algorithm-name: table-inline-order
            key-generate-strategy:
              column: id
              key-generator-name: snowflake
          t_mall_order_sku:
            actual-data-nodes: shardingorder$->{0..1}.t_mall_order_sku$->{0..1}
            # 配置分库策略
            databaseStrategy:
              standard:
                shardingColumn: id
                shardingAlgorithmName: database-inline
            table-strategy:
              standard:
                sharding-column: id
                sharding-algorithm-name: table-inline-order-sku
            key-generate-strategy:
              column: id
              key-generator-name: snowflake
        sharding-algorithms:
          database-inline:
            type: INLINE
            props:
              algorithm-expression: shardingorder$->{id % 2}
          table-inline-order:
            type: INLINE
            props:
              algorithm-expression: t_mall_order$->{id % 2}
          table-inline-order-sku:
            type: INLINE
            props:
              algorithm-expression: t_mall_order_sku$->{id % 2}
        key-generators:
          snowflake:
            type: SNOWFLAKE
            props:
              worker-id: 123

4、打开动态数据源的分布式事务配置

      # 开启seata代理，开启后默认每个数据源都代理，如果某个不需要代理可单独关闭
      seata: true

5、打开Seata本身的配置开关

seata:
  enabled: true

6、完整Nacos配置文件
