关于httpclient乱码问题我改写了源码
改写的地方
org.apache.commons.httpclient.util.EncodingUtil

 public static byte[] getAsciiBytes(final String data) {

        if (data == null) {
            throw new IllegalArgumentException("Parameter may not be null");
        }

        try {
            return data.getBytes("UTF-8");
        } catch (UnsupportedEncodingException e) {
            throw new HttpClientError("HttpClient requires ASCII support");
        }
    }

org.apache.commons.httpclient.methods.multipart.StringPart

 public StringPart(String name, String value, String charset) {
        
        super(
            name,
            DEFAULT_CONTENT_TYPE,
            charset == null ? "UTF-8" : charset,
            DEFAULT_TRANSFER_ENCODING
        );
        if (value == null) {
            throw new IllegalArgumentException("Value may not be null");
        }
        if (value.indexOf(0) != -1) {
            // See RFC 2048, 2.8. "8bit Data"
            throw new IllegalArgumentException("NULs may not be present in string parts");
        }
        this.value = value;
    }

org.apache.commons.httpclient.methods.multipart.FilePart

 public FilePart(String name, PartSource partSource, String contentType, String charset) {
