构造器详细资料

BeanPropertyRowMapper

public BeanPropertyRowMapper()

Create a new BeanPropertyRowMapper.

BeanPropertyRowMapper

public BeanPropertyRowMapper(Class<T> requiredType)

Create a new BeanPropertyRowMapper.

方法详细资料

setRequiredType

public void setRequiredType(Class<T> requiredType)

Set the type that each result object is expected to match.

If not specified, the column value will be exposed as returned by the JDBC driver.

isCaseInsensitive

public boolean isCaseInsensitive()

setCaseInsensitive

public void setCaseInsensitive(boolean caseInsensitive)

mapRow

public T mapRow(ResultSet rs,
       int rowNum)
         throws SQLException

从接口复制的说明: RowMapper

实现这个方法为结果集的一行记录进行转换，并将最终转换结果返回。如果返回为 null 等同于忽略该行。 需要注意，不要调用结果集的 next() 方法。

参数:

rs - 记录集

rowNum - 当前记录的行号

抛出:

SQLException

getColumnValue

protected Object getColumnValue(ResultSet rs,
                    int index,
                    Class<?> requiredType)
                         throws SQLException

取得指定列的值

抛出:

SQLException

newInstance

public static <T> 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
