- - org.springframework.core.io.ByteArrayResource

所有已实现的接口:
InputStreamSource, Resource
直接已知子类:
TransformedResource
```
public class ByteArrayResource
extends AbstractResource
```
Resource implementation for a given byte array.
Creates a ByteArrayInputStream for the given byte array.
Useful for loading content from any given byte array, without having to resort to a single-use InputStreamResource. Particularly useful for creating mail attachments from local content, where JavaMail needs to be able to read the stream multiple times.
从以下版本开始:
1.2.3

```
public ByteArrayResource(byte[] byteArray)
```
    Create a new ByteArrayResource.
    参数:
    byteArray - the byte array to wrap
  - ByteArrayResource
```
public ByteArrayResource(byte[] byteArray,
                         String description)
```
    Create a new ByteArrayResource with a description.
    参数:
    byteArray - the byte array to wrap
    description - where the byte array comes from

  - getByteArray
```
public final byte[] getByteArray()
```
    Return the underlying byte array.
  - exists
```
public boolean exists()
```
    This implementation always returns true.
    指定者:
    exists 在接口中 Resource
    覆盖:
    exists 在类中 AbstractResource
  - contentLength
```
public long contentLength()
```
    This implementation returns the length of the underlying byte array.
    指定者:
    contentLength 在接口中 Resource
    覆盖:
    contentLength 在类中 AbstractResource

    InputStreamSource.getInputStream()
  - getInputStream
```
public InputStream getInputStream()
                           throws IOException
```
    This implementation returns a ByteArrayInputStream for the underlying byte array.
    返回:
    the input stream for the underlying resource (must not be null)
    抛出:
    FileNotFoundException - if the underlying resource doesn't exist
    IOException - if the content stream could not be opened

    ByteArrayInputStream
  - getDescription
```
public String getDescription()
```
    This implementation returns a description that includes the passed-in description, if any.

  - equals
```
public boolean equals(Object obj)
```
    This implementation compares the underlying byte array.

  - hashCode
```
public int hashCode()
```
    This implementation returns the hash code based on the underlying byte array.
