使用 Spring JDBC 连接到 MS SQL Server 2017 HA 侦听器时出现问题

Question

我们正在连接到 PCF 中的 MS SQL 服务器 HA 侦听器。 以下是我们用来创建数据源和连接模板的逻辑 -

    public DataSource internetpoolDataSource(Cloud cloud) {
        PoolConfig poolConfig = getPoolConfig();
        DataSourceConfig dbConfig = new DataSourceConfig(poolConfig, null, Arrays
                .asList(new String[] { "HikariCpPooledDataSourceCreator", "BasicDbcpPooledDataSourceCreator" }));
        logger.info("Connecting to {} ", env.getProperty("internetdb.service"));
        DataSource dataSource = null;
        try {
            dataSource = connectionFactory().dataSource(env.getProperty("internetdb.service"), dbConfig);
        }
        catch (Exception e) {
            logger.error("Error obtained while creating service connector: {}", ExceptionUtils.getStackTrace(e));
            throw e;
        }
        return dataSource;
    }

    /**
     * 
     * @param dataSource
     * @return
     */
    @Bean(name = "internetpoolJdbcTemplate")
    public JdbcOperations internetpoolJdbcTemplate(@Qualifier("internetpoolDataSource") DataSource dataSource){
        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
        JdbcOperations proxy = null;
        try{
            logger.info("Attempting to connect to primary");
            ProxyInternetJdbcTemplateHandler proxyInternetJdbcTemplateHandler = new  ProxyInternetJdbcTemplateHandler(jdbcTemplate);
            proxy = (JdbcOperations) Proxy.newProxyInstance(jdbcTemplate.getClass().getClassLoader(), jdbcTemplate.getClass().getInterfaces(), proxyInternetJdbcTemplateHandler);
        }
        catch(Exception e){
            proxy =  jdbcTemplate;
            logger.error("Exception while creating internetpool failover proxy",e);
        }
        return proxy;
    }

该字符串看起来像 - jdbc:sqlserver://<host>:<port>;databaseName=<database>;user=<user>;password={<password>};MultiSubnetFailover=true

这会导致一个看起来像这样的异常 -

当我们尝试不带括号的密码时，我得到一个异常，内容为 -

org.springframework.beans.factory.BeanCreationException: Error registering service factory; nested exception is org.springframework.cloud.CloudException: No suitable ServiceConnectorCreator found: service id=test-sqldb, service info type=org.springframework.cloud.service.BaseServiceInfo, connector type=interface javax.sql.DataSource

需要注意的一点是，我们能够使用这些连接字符串并连接到各个节点。 问题仅在于 HA 侦听器
