```
The MappingLdifReader is an adaptation of the FlatFileItemReader built around an LdifParser. It differs from the standard LdifReader in its ability to map LdapAttributes objects to POJOs.
The MappingLdifReaderrequires an RecordMapper implementation. If mapping is not required, the LdifReader should be used instead. It simply returns an LdapAttributes object which can be consumed and manipulated as necessary by ItemProcessor or any output service.
As with the FlatFileItemReader, the strict option differentiates between whether or not to require the resource to exist before processing. In the case of a value set to false, a warning is logged instead of an exception being thrown.

public MappingLdifReader()
```
- 方法详细资料
  - setStrict
```
public void setStrict(boolean strict)
```
    In strict mode the reader will throw an exception on AbstractItemCountingItemStreamItemReader.open(org.springframework.batch.item.ExecutionContext) if the input resource does not exist.
    参数:
    strict - false by default
  - setSkippedRecordsCallback
```
public void setSkippedRecordsCallback(RecordCallbackHandler skippedRecordsCallback)
```
    RecordCallbackHandler implementations can be used to take action on skipped records.
    参数:
    skippedRecordsCallback - will be called for each one of the initial skipped lines before any items are read.
  - setRecordsToSkip
```
public void setRecordsToSkip(int recordsToSkip)
```
    Public setter for the number of lines to skip at the start of a file. Can be used if the file contains a header without useful (column name) information, and without a comment delimiter at the beginning of the lines.
    参数:
    recordsToSkip - the number of lines to skip
  - setRecordMapper
```
public void setRecordMapper(RecordMapper<T> recordMapper)
```
    Setter for object mapper. This property is required to be set.
    参数:
    recordMapper - maps record to an object
  - doClose
```
protected void doClose()
                throws java.lang.Exception
```

  - doRead
```
protected T doRead()
            throws java.lang.Exception
```
    从类复制的说明: AbstractItemCountingItemStreamItemReader
    Read next item from input.
    指定者:
    doRead 在类中 AbstractItemCountingItemStreamItemReader<T>
    返回:
    an item or null if the data source is exhausted
    抛出:
    java.lang.Exception - Allows subclasses to throw checked exceptions for interpretation by the framework
