java8字符集，如何解决字符乱码问题

1、java8支持的字符集：@Test public void test() { Map<String,Charset> map = Charset.availableCharsets(); Set<Map.Entry<String,Charset>> entrySet = map.entrySet(); for(Map.Entry<String,Charset> entry:entrySet) { System.out.println(entry.getKey() + "=" + entry.getValue()); } }

2、运行程序查看所支持的字符集

3、编码与解码字符：public void test1() throws Exception { Charset charset = Charset.forName("GBK"); CharsetEncoder charsetEncoder = charset.newEncoder(); CharsetDecoder charsetDecoder = charset.newDecoder(); CharBuffer charBuffer = CharBuffer.allocate(1024); charBuffer.put("你好，中国威武"); charBuffer.flip(); //编码 ByteBuffer byteBuffer = charsetEncoder.encode(charBuffer); //解码 CharBuffer charBuffer1 = charsetDecoder.decode(byteBuffer); System.out.println(charBuffer1.toString()); }

4、运行程序查看程序运行结果：

5、GBK与UTF-8字符编码转换@Test pu水瑞侮瑜blic void test2() throws Ex艘早祓胂ception { Charset charset = Charset.forName("GBK"); CharsetEncoder charsetEncoder = charset.newEncoder(); CharBuffer charBuffer = CharBuffer.allocate(1024); charBuffer.put("你好，中国威武"); charBuffer.flip(); //编码 ByteBuffer byteBuffer = charsetEncoder.encode(charBuffer); //解码 CharBuffer charBuffer1 = Charset.forName("UTF-8").decode(byteBuffer); System.out.println(charBuffer1.toString()); }
