    <head>
        <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
        <title></title>
        <script type="text/javascript" src="static/js/crypto-js.js"></script>
        <script>
            function AesTo(text){
                var key = CryptoJS.enc.Utf8.parse("PB1234567890PB");
                var iv = CryptoJS.enc.Utf8.parse("PB1234567890PB");
                var srcs = CryptoJS.enc.Utf8.parse(encodeURI(text));
                var context = CryptoJS.AES.encrypt(srcs,key,{
                    iv:iv,
                    mode:CryptoJS.mode.CBC,
                    padding:CryptoJS.pad.Pkcs7
                });
                $.ajax({
                    url:url,
                    type:"POST",
                    data:{
                        context:context.toString()
                    },
                    success:function(res){
                        console.log(res);
                    }
                })
            }
        </script>
    </head>
    <body>
    </body>
</html>
后端：
package com.cn.aes.util
import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import sun.misc.BASE64Decoder;
import com.alibaba.druid.util.StringUtils;

public class aesUtil{

    //base64
    private byte[] base64Decode(String base64Code) throws Exception{
        return StringUtils.isEmpty(base64Code) ? null:new BASE64Decoder().decodeBuffer(base64Code);
    }
    //AES 解码
    public String aesDecrypt(String context,String key,String iv) throws Exception{
        return StringUtils.isEmpty(context) ? null : java.net.URLDecoder.decode(aesDecryptByBytes(base64Decode(context),key.getBytes(),iv.getBytes()),"UTF-8");
    }
    public String aesDecryptByBytes(byte[] context,byte[] key,byte[] iv) throws Exception{
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE,new SecretKeySpec(key,"AES"),new IvParameterSpec(iv));
        byte[] result cipher.doFinal(context);
        return new String(result);
    }
}
------------------------------
后端通过方法调用   String  contextNew = aesUtil.aesDecrypt(context,"PB1234567890PB","PB1234567890PB");
