spring-boot代码手动装配

tidb 数据源

@Configuration
@MapperScan(basePackages = "com.demo.das.tidb.mapper", sqlSessionFactoryRef = "tidbSqlSessionFactory")
public class TidbDataSourceConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.tidb")
    public HikariConfig tidbConfig() {
        return new HikariConfig();
    }

    @Bean
    public HikariDataSource tidbDataSource(HikariConfig tidbConfig) {
        HikariDataSource dataSource = new HikariDataSource(tidbConfig);
        return dataSource;
    }

    @Bean
    public SqlSessionFactory tidbSqlSessionFactory(HikariDataSource tidbDataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(tidbDataSource);
        ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        bean.setConfigLocation(resolver.getResource("classpath:mybatis-config.xml"));
        bean.setMapperLocations(resolver.getResources("classpath:mapper/tidb/*.xml"));
        bean.setTypeAliasesPackage("com.demo.entity");
        return bean.getObject();
    }

    @Bean("tidbTransactionManger")
    public DataSourceTransactionManager tidbTransactionManger(DataSource tidbDataSource) {
        return new DataSourceTransactionManager(tidbDataSource);
    }
}

clickhouse数据源

@Configuration
@MapperScan(basePackages = "com.demo.das.clickhouse.mapper", sqlSessionFactoryRef = "clickHouseSqlSessionFactory")
public class ClickHouseDataSourceConfig {


    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.clickhouse")
    public HikariConfig clickHouseConfig() {
        return new HikariConfig();
    }

    @Bean
    public HikariDataSource clickHouseDataSource(HikariConfig clickHouseConfig) {
        HikariDataSource dataSource = new HikariDataSource(clickHouseConfig);
        return dataSource;
    }

    @Bean
    public SqlSessionFactory clickHouseSqlSessionFactory(DataSource clickHouseDataSource) throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(clickHouseDataSource);
        ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        bean.setConfigLocation(resolver.getResource("classpath:mybatis-config.xml"));
        bean.setMapperLocations(resolver.getResources("classpath:mapper/clickhouse/*.xml"));
        bean.setTypeAliasesPackage("com.demo.entity");
        return bean.getObject();
    }
