strut2中文乱码
页面设置编码：gb2312
其余所有设置均为:utf-8
tomcat同样设URIEcoding：utf-8
现在要早Action中接受页面传过来的值
无论怎么转都是乱码：我试过的方法有

Java code

HttpServletRequest request = ServletActionContext.getRequest();        request.setCharacterEncoding("gb2312");        String str = request.getParameter("msgContent");        System.out.println(str);        System.out                .println(new String(this.getMsgContent().getBytes(), "utf-8"));        System.out                .println(new String(this.getMsgContent().getBytes(), "gb2312"));        System.out.println(new String(this.getMsgContent().getBytes(), "gbk"));        System.out.println("可以正常么1：" + this.getMsgContent());// 1        System.out.println("可以正常么2：" + this.getMsgContent().getBytes());// 2        System.out.println("可以正常么3：" + this.getMsgContent().getBytes("GB2312"));// 3        System.out.println("可以正常么4："                + this.getMsgContent().getBytes("ISO-8859-1"));// 4        System.out.println("可以正常么5："                + new String(this.getMsgContent().getBytes()));// 5        System.out.println("可以正常么6："                + new String(this.getMsgContent().getBytes(), "GB2312"));// 6        System.out.println("可以正常么7："                + new String(this.getMsgContent().getBytes(), "ISO-8859-1"));// 7        System.out.println("可以正常么8："                + new String(this.getMsgContent().getBytes("GB2312")));// 8        System.out                .println("可以正常么9："                        + new String(this.getMsgContent().getBytes("GB2312"),                                "GB2312"));// 9        System.out.println("可以正常么10："                + new String(this.getMsgContent().getBytes("GB2312"),                        "ISO-8859-1"));// 10        System.out.println("可以正常么11："                + new String(this.getMsgContent().getBytes("ISO-8859-1")));// 11        System.out                .println("====================================12=====================");        System.out.println("可以正常么12："                + new String(this.getMsgContent().getBytes("ISO-8859-1"),                        "GB2312"));// 12        System.out                .println("====================================13=====================");        System.out.println("可以正常么1："                + new String(this.getMsgContent().getBytes("ISO-8859-1"),                        "ISO-8859-1"));// 13        String stra = URLDecoder.decode(this.getMsgContent(), "utf-8");//        String stra1 = URLDecoder.decode(this.getMsgContent(), "gbk");//        String stra2 = URLDecoder.decode(this.getMsgContent(), "gb2312");//        System.out.println(stra);        System.out.println(stra1);        System.out.println(stra2);//运行结果如下：????????????????????????????????????????????????????可以正常么1：?????????????可以正常么2：[B@1cf806b可以正常么3：[B@11272ec可以正常么4：[B@36fc18可以正常么5：?????????????可以正常么6：?????????????可以正常么7：?????????????可以正常么8：?????????????可以正常么9：?????????????可以正常么10：?????????????可以正常么11：?????????????====================================12=====================可以正常么12：?????????????====================================13=====================可以正常么1：????????????????????????????????????????????????????

因为你页面设置了编码为gb2312， 所以你传递到后台的数据相当于用UTF-8 解析gb2312编码的数据，当然就会出现乱码，建议你在页面设置为UTF-8，这样对以后有好处，不会出现乱码。或者你把Action中的编码格式改为gb2312也可以。

试试这个

new String(this.getMsgContent().getBytes("UTF-8"), "GB2312")

LZ可以再web.xml中试试这样的配置
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

public static byte[] decodeHex(char[] data) throws DecoderException {
int len = data.length;

if ((len & 0x1) != 0) {
throw new DecoderException("Odd number of characters.");
}

byte[] out = new byte[len >> 1];

int i = 0;
for (int j = 0; j < len; ++i) {
int f = toDigit(data[j], j) << 4;
++j;
f |= toDigit(data[j], j);
++j;
out[i] = (byte) (f & 0xFF);
}

return out;
}

protected static int toDigit(char ch, int index) throws DecoderException {
int digit = Character.digit(ch, 16);
if (digit == -1) {
throw new DecoderException("Illegal hexadecimal charcter " + ch
+ " at index " + index);
}
return digit;
}

public static void main(String[] args) throws DecoderException {
String soruce = "xxx";
byte[] a = decodeHex(soruce.toCharArray());
soruce = new String(a);
System.out.println("==="+soruce);
}

我增减遇到过在jsp页面传中文到struts中，jsp页面的编码是UTF-8的，java是GBK的，然后在jsp页面用

Java code

URLEncoder.encode(String 字段名,String 编码类型)
