String类型变量转成InputStream或者Reader流类型，用于sax解析的输入,转成InputStream时中文乱码，转成Reader流就好了

JAVA将字符串变为输入流 
关于字符串转化为输入流，我找到2种方法： 
用StringReader将字符串转化为Reader 

用ByteArrayInputStream将字符串转化为InputStream.

示例代码如下： 

public static InputStream getStringInputStream(String s) { 
    if (s != null && !s.equals("")) { 
        try { 

            ByteArrayInputStream stringInputStream = new ByteArrayInputStream( 
                    s.getBytes("UTF-8")); 

或者

	InputStream is = new ByteArrayInputStream(text.getBytes("UTF-8"));

            return stringInputStream; 
        } catch (Exception e) { 

            e.printStackTrace(); 
        } 
    } 
    return null; 
} 

public static Reader getStringReader(String s) { 
    if (s != null && !s.equals("")) { 
        try { 

            StringReader stringReader = new StringReader(s); 
            return stringReader; 
        } catch (Exception e) { 

            e.printStackTrace(); 
        } 
    } 
    return null; 
}
