getOut

public ZipOutputStream getOut()

获取原始的ZipOutputStream

Returns:

ZipOutputStream

add

public ZipWriter add(boolean withSrcDir,
                     FileFilter filter,
                     File... files)
              throws IORuntimeException

对文件或文件目录进行压缩

Parameters:

withSrcDir - 是否包含被打包目录，只针对压缩目录有效。若为false，则只压缩目录下的文件或目录，为true则将本目录也压缩

filter - 文件过滤器，通过实现此接口，自定义要过滤的文件（过滤掉哪些文件或文件夹不加入压缩），null表示不过滤

files - 要压缩的源文件或目录。如果压缩一个文件，则为该文件的全路径；如果压缩一个目录，则为该目录的顶层目录路径

Returns:

this

Throws:

IORuntimeException - IO异常

Since:

resources - 需要压缩的资源，资源的路径为Resource.getName()

Returns:

this

Throws:

IORuntimeException - IO异常

add

public ZipWriter add(String path,
                     InputStream in)
              throws IORuntimeException

添加文件流到压缩包，添加后关闭输入文件流
如果输入流为null，则只创建空目录

Parameters:

path - 压缩的路径, null和""表示根目录下

in - 需要压缩的输入流，使用完后自动关闭，null表示加入空目录

Returns:

this
