SqlParameterSource

public class MapSqlParameterSource
extends AbstractSqlParameterSource

SqlParameterSource implementation that holds a given Map of parameters.

This class is intended for passing in a simple Map of parameter values to the methods of the NamedJdbcTemplate class.

The addValue methods on this class will make adding several values easier. The methods return a reference to the MapSqlParameterSource itself, so you can chain several method calls together within a single statement.

addValue(String, Object)

MapSqlParameterSource

public MapSqlParameterSource(Map<String,?> values)

Create a new MapSqlParameterSource based on a Map.

参数：

values - a Map holding existing parameter values (can be null)

方法详细信息

addValue

public MapSqlParameterSource addValue(String paramName,
                                      Object value)

Add a parameter to this parameter source.

参数：

paramName - the name of the parameter

value - the value of the parameter

返回：

a reference to this parameter source, so it's possible to chain several calls together

addValue

public MapSqlParameterSource addValue(String paramName,
                                      Object value,
                                      int sqlType)

Add a parameter to this parameter source.

参数：

paramName - the name of the parameter

value - the value of the parameter

sqlType - the SQL type of the parameter

返回：

a reference to this parameter source, so it's possible to chain several calls together

addValue

public MapSqlParameterSource addValue(String paramName,
                                      Object value,
                                      int sqlType,
                                      String typeName)

Add a parameter to this parameter source.

参数：

paramName - the name of the parameter

value - the value of the parameter

sqlType - the SQL type of the parameter

typeName - the type name of the parameter

返回：

a reference to this parameter source, so it's possible to chain several calls together

addValues

public MapSqlParameterSource addValues(Map<String,?> values)

Add a Map of parameters to this parameter source.

参数：

values - a Map holding existing parameter values (can be null)

返回：

a reference to this parameter source, so it's possible to chain several calls together
