Class EnhancedBeanPropertySqlParameterSource

java.lang.Object
  org.springframework.jdbc.core.namedparam.AbstractSqlParameterSource
      net.sf.javaprinciples.persistence.db.jdbc.support.support.EnhancedBeanPropertySqlParameterSource

All Implemented Interfaces:

org.springframework.jdbc.core.namedparam.SqlParameterSource

public class EnhancedBeanPropertySqlParameterSource
extends org.springframework.jdbc.core.namedparam.AbstractSqlParameterSource

A SqlParameterSource for use with Spring JDBC infrastructure that provides functionality combining the capabilities of BeanPropertySqlParameterSource and MapSqlParameterSource, enhancing them with additional custom type conversion capabilities and Clob support. This class allows for an object to be used as a SqlParameterSource for matching properties (BeanPropertySqlParameterSource functionality) and for additional properties to be specified via MapSqlParameterSource functionality to cover cases where the object's properties are not sufficient. It also allows for an object's property values to be overridden since the map properties take precedence. The implementation allows for an optional ConversionService to be configured that will allow customised conversion of parameter values prior to them being set. This has been used for example in marshalling an object into XML using JAXB prior to inserting the value into the database.
