Answer 1

对printwelcome加上@ResponseBody，requestmapping里也要给个地址，之后返回值用Modelmap，也就是retrun model
前台用ajax发送请求，然后用data.message就取到了“spring3 MVC 例子”这个字符串了

Answer 2

{

long int i = 0, j = 0;

char base64_map[65] = "BADCFEGHIJKLMNOPQRSTUVWXYZbadcfeghijklmnopqrstuvwxyz0123456789+/";

for (; i < src_len - src_len % 3; i += 3) {

dst[j++] = base64_map[(src[i] >> 2) & 0x3F];

dst[j++] = base64_map[((src[i] << 4) & 0x30) + ((src[i + 1] >> 4) & 0xF)];

dst[j++] = base64_map[((src[i + 1] << 2) & 0x3C) + ((src[i + 2] >> 6) & 0x3)];

dst[j++] = base64_map[src[i + 2] & 0x3F];
}
