限定符和类型	方法和说明
protected void	bind(io.r2dbc.spi.Statement statement, int index, Object value)
protected void	bindNull(io.r2dbc.spi.Statement statement, int index, Class<?> type)
protected SqlRequest	convertRequest(SqlRequest sqlRequest) 转换SQL为R2dbcSqlRequest,由于不同数据库的预编译占位符不同,需要进行转换
protected reactor.core.publisher.Flux<io.r2dbc.spi.Result>	doExecute(io.r2dbc.spi.Connection connection, SqlRequest request) 使用指定的Connection执行SQL并返回执行结果
reactor.core.publisher.Mono<Void>	execute(org.reactivestreams.Publisher<SqlRequest> request) 执行SQL语句,忽略结果.
protected int	getBindFirstIndex()
protected String	getBindSymbol()
protected abstract reactor.core.publisher.Mono<io.r2dbc.spi.Connection>	getConnection() 获取连接
protected io.r2dbc.spi.Statement	prepareStatement(io.r2dbc.spi.Statement statement, SqlRequest request)
protected abstract void	releaseConnection(reactor.core.publisher.SignalType type, io.r2dbc.spi.Connection connection) 释放连接，不建议实现此方法，推荐在getConnection里使用Mono.usingWhen(Publisher, Function, Function)来处理.
<E> reactor.core.publisher.Flux<E>	select(org.reactivestreams.Publisher<SqlRequest> request, ResultWrapper<E,?> wrapper) 执行查询语句,并使用同一个包装器包装返回结果
protected reactor.core.publisher.Flux<SqlRequest>	toFlux(org.reactivestreams.Publisher<SqlRequest> request) 将SQL流转为Flux
reactor.core.publisher.Mono<Integer>	update(org.reactivestreams.Publisher<SqlRequest> request) 执行更新语句,支持 update,delete,insert
