JAVA NIO之Character Set 明白以下几个概念: 字母集(Character Set),汉字,特殊符号,字母这些都是字符集; 字符编码集(Coded character set),将字符集的字符使用数字进行编码;比如ASCII,就是定义了一组字符编码集;Unicode 字符编码框架(Character-encoding schema),描述如何将一组字符编码转换为字节(byte);所以框架核心...
分析原因,应该是在执行第一个getParameter()的时候,java将会按照编码分析所有的提交内容,而后续的getParameter()不再进行分析,所以setCharacterEncoding()无效。而对于GET方法提交表单是,提交的内容在URL中,一开始就已经按照编码分析提交内容,setCharacterEncoding()自然就无效。 get需在Tomcat的server.xml中的: <Connector...

The Java platform stores character values using Unicode conventions. Character stream I/O automatically translates this internal format to and from the local character set. In Western locales, the local character set is usually an 8-bit superset of ASCII. For most applications, I/O with character...
