Constructor Detail

BigQueryFileMessageHandler

public BigQueryFileMessageHandler(BigQueryTemplate bigQueryTemplate)

Method Detail

doInit

protected void doInit()

Overrides:

doInit in class org.springframework.integration.handler.AbstractReplyProducingMessageHandler

setTableNameExpression

public void setTableNameExpression(org.springframework.expression.Expression tableNameExpression)

Sets the SpEL Expression to evaluate to determine the table name.

Parameters:

tableNameExpression - the SpEL expression used to evaluate the table name

setTableName

public void setTableName(String tableName)

Sets the BigQuery table name to use. This overwrites any previous settings made by setTableNameExpression(org.springframework.expression.Expression).

Parameters:

tableName - name of the BigQuery table

setFormatOptionsExpression

public void setFormatOptionsExpression(org.springframework.expression.Expression formatOptionsExpression)

Sets the SpEL Expression used to determine the FormatOptions for the handler.

Parameters:

formatOptionsExpression - the SpEL expression used to evaluate the FormatOptions

setFormatOptions

public void setFormatOptions(FormatOptions formatOptions)

Sets the handler's FormatOptions which describe the type/format of data files being loaded. This overwrites any previous settings made by setFormatOptionsExpression(org.springframework.expression.Expression).

Parameters:

formatOptions - the format of the data file being loaded

setTableSchemaExpression

public void setTableSchemaExpression(org.springframework.expression.Expression tableSchemaExpression)

Sets the SpEL expression used to determine the Schema for the handler.

Parameters:

tableSchemaExpression - the SpEL expression used to evaluate the Schema.

setTableSchema

public void setTableSchema(Schema schema)

Sets the Schema of the table to load for the handler.

Parameters:

schema - the schema of the table to load.

setTimeout

public void setTimeout(Duration timeout)

Sets the Duration to wait for a file to be loaded into BigQuery before timing out when waiting synchronously.

Parameters:

timeout - the Duration timeout to wait for a file to load

setSync

public void setSync(boolean sync)

A boolean indicating if the BigQueryFileMessageHandler should synchronously wait for each file to be successfully loaded to BigQuery.

If set to true, the handler runs synchronously and returns Job for message responses. If set to false, the handler will return ListenableFuture of the Job as the response for each message.

Parameters:

sync - whether BigQueryFileMessageHandler should wait synchronously for jobs to complete. Default is false (async).

handleRequestMessage

protected Object handleRequestMessage(org.springframework.messaging.Message<?> message)

Specified by:

handleRequestMessage in class org.springframework.integration.handler.AbstractReplyProducingMessageHandler
