RES加密解密长文本中文JAVA与JS方法，前后端通用

 更新：RSAUtils.java中

return Base64.encodeBase64URLSafeString(dataReturn);

替换为

return Base64.encodeBase64String(dataReturn);

否则java加密的内容JS解密不了

//测试  testText为需要加密的字符串  JS加密会有一定几率不能解密，所以可以把加密后的内容解密一次，如果解密后跟加密前的内容完全相等，则加密成功，可以把加密后的内容发给后端，如果不想等则重新加密一次再次判断
//运行10000次结果  成功次数:9456    失败次数：544
