BeanTransformerAdapter

public BeanTransformerAdapter()

Create a new BeanPropertyRowMapper for bean-style configuration.

另请参阅:

setMappedClass(java.lang.Class<T>), setCheckFullyPopulated(boolean)

BeanTransformerAdapter

public BeanTransformerAdapter(Class<T> mappedClass)

Create a new BeanPropertyRowMapper, accepting unpopulated properties in the target bean.

Consider using the newInstance(java.lang.Class<T>) factory method instead, which allows for specifying the mapped type once only.

参数:

mappedClass - the class that each row should be mapped to

BeanTransformerAdapter

public BeanTransformerAdapter(Class<T> mappedClass,
                      boolean checkFullyPopulated)

Create a new BeanPropertyRowMapper.

参数:

mappedClass - the class that each row should be mapped to

checkFullyPopulated - whether we're strictly validating that all bean properties have been mapped from corresponding database fields

方法详细资料

setMappedClass

public void setMappedClass(Class<T> mappedClass)

Set the class that each row should be mapped to.

initialize

protected void initialize(Class<T> mappedClass)

Initialize the mapping metadata for the given class.

参数:

mappedClass - the mapped class.

getMappedClass

public final Class<T> getMappedClass()

Get the class that we are mapping to.

setCheckFullyPopulated

public void setCheckFullyPopulated(boolean checkFullyPopulated)

Set whether we're strictly validating that all bean properties have been mapped from corresponding database fields.

Default is false, accepting unpopulated properties in the target bean.

isCheckFullyPopulated

public boolean isCheckFullyPopulated()

Return whether we're strictly validating that all bean properties have been mapped from corresponding database fields.

setPrimitivesDefaultedForNullValue

public void setPrimitivesDefaultedForNullValue(boolean primitivesDefaultedForNullValue)

Set whether we're defaulting Java primitives in the case of mapping a null value from corresponding database fields.

Default is false, throwing an exception when nulls are mapped to Java primitives.

isPrimitivesDefaultedForNullValue

public boolean isPrimitivesDefaultedForNullValue()

Return whether we're defaulting Java primitives in the case of mapping a null value from corresponding database fields.

initBeanWrapper

protected void initBeanWrapper(org.springframework.beans.BeanWrapper bw)

Initialize the given BeanWrapper to be used for row mapping. To be called for each row.

The default implementation is empty. Can be overridden in subclasses.

参数:

bw - the BeanWrapper to initialize

getColumnValue

protected Object getColumnValue(ResultSet rs,
                    int index,
                    PropertyDescriptor pd)
                         throws SQLException

Retrieve a JDBC object value for the specified column.

The default implementation calls JdbcUtils.getResultSetValue(java.sql.ResultSet, int, Class). Subclasses may override this to check specific value types upfront, or to post-process values return from getResultSetValue.

参数:

rs - is the ResultSet holding the data

index - is the column index

pd - the bean property that each result object is expected to match (or null if none specified)

返回:

the Object value

抛出:

SQLException - in case of extraction failure

另请参阅:

JdbcUtils.getResultSetValue(java.sql.ResultSet, int, Class)

newInstance

public static <T> org.springframework.jdbc.core.BeanPropertyRowMapper<T> newInstance(Class<T> mappedClass)

Static factory method to create a new BeanPropertyRowMapper (with the mapped class specified only once).

参数:

mappedClass - the class that each row should be mapped to

transformTuple

public Object transformTuple(Object[] tuple,
                    String[] aliases)

指定者:

transformTuple 在接口中 org.hibernate.transform.ResultTransformer

transformList

public List transformList(List list)

指定者:

transformList 在接口中 org.hibernate.transform.ResultTransformer
