添加到 Spring 项目的 HikariCP 出现错误

Question

我使用提供的 HikariCP 在项目中添加了一个新的数据源配置：

@Configuration
public class DataSourceConfig {

    @Autowired
    private DataSource dataSource;

    @Bean
    public DataSource customDataSource(DataSourceProperties properties) {

        final CustomHikariDataSource dataSource = (CustomHikariDataSource) properties
            .initializeDataSourceBuilder().type(CustomHikariDataSource.class).build();
        if (properties.getName() != null) {
            dataSource.setPoolName(properties.getName());
        }
        return dataSource;
    }

    @Bean
    @Scope(
        value = ConfigurableBeanFactory.SCOPE_PROTOTYPE,
        proxyMode = ScopedProxyMode.TARGET_CLASS)
    public JdbcTemplate jdbcTemplate() throws SQLException {
        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
        return jdbcTemplate;
    }

    private static class CustomHikariDataSource extends HikariDataSource {
        @Override
        public Connection getConnection() throws SQLException {

            Connection connection = super.getConnection();
//            connection.setSchema(Utilities.getTenantId());
            return connection;
        }
    }
}

之后我立即开始得到这些：

项目在此之前运行良好。这些错误的问题是什么以及如何解决它们？

Answer 1

您正在创建一个 Datasource Bean 并且还在相同的配置中自动装配它 class

将 Datasource Bean 移动到不同的配置 class
