Create a new ResultMapper.

MappingRowMapper

public MappingRowMapper(Class<T> mapperClass,
                        TypeHandlerRegistry handlerRegistry)

Create a new ResultMapper.

方法详细资料

getMapperClass

public Class<T> getMapperClass()

getCategory

public String getCategory()

从接口复制的说明: TableInfo

分类(对于mysql 是 db，对于 pg 是 schema，对于 oracle 是 owner)

指定者:

getCategory 在接口中 TableInfo

getTableName

public String getTableName()

从接口复制的说明: TableInfo

表名

指定者:

getTableName 在接口中 TableInfo

isCaseInsensitive

public boolean isCaseInsensitive()

setCaseInsensitive

public void setCaseInsensitive(boolean caseInsensitive)

findFieldInfoByProperty

public FieldInfo findFieldInfoByProperty(String propertyName)

allFieldInfoByProperty

public Collection<FieldInfo> allFieldInfoByProperty()

getTableInfo

public TableInfo getTableInfo()

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。

指定者:

mapRow 在接口中 RowMapper<T>

参数:

rs - 记录集

rowNum - 当前记录的行号

抛出:

SQLException

newInstance

public static <T> MappingRowMapper<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

newInstance

public static <T> MappingRowMapper<T> newInstance(Class<T> mappedClass,
                                                  TypeHandlerRegistry registry)

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
