ip17mon-java's Introduction

IP 17mon java version, 比官方的速度快很多，支持监视文件改动自动加载

IP库请从 ipip.net 下载

添加依赖：

<dependency>
  <groupId>com.qiniu</groupId>
  <artifactId>ip17mon</artifactId>
  <version>0.2.1</version>
</dependency>

使用方法：

首选构建一个 Locator ，支持从不同的地方加载IP库，比如远程URL，或者本地的文件。

//从URL加载IP库
String ipBaseUrl = "http://xxx.example.com/ip.dat";
Locator locator = Locator.loadFromNet(ipBaseUrl);

//从本地加载IP库
String ipBasePath = "/tmp/ip.dat";
Locator locator = Locator.loadFromLocal(ipBasePath);

然后使用 find 方法查询：

LocationInfo ipInfo = locator.find("180.163.159.7");
System.out.println(ipInfo.toString());

ip17mon-java's Issues

偶发乱码

flink(多线程环境) 输出 json 到 elasticsearch, 同一个 ip 地址, 有的记录显示正常, 有的显示乱码.
对比官方 java 修改2行后, 再也没出现过乱码.
不懂原理, 求解答...
加上了 ut8编码, 和 split中的-1

  LocationInfo buildInfo(byte[] bytes, int offset, int len) {
    String str = new String(bytes, offset, len, Charset.forName("UTF-8"));
    String[] ss = str.split("\t", -1);

单元测试的时候，有时通过，有时不通过

单元测试中执行了find（ip）的函数调用，但是有时可以正常解析，有时又报下面的错误：
java.lang.ArrayIndexOutOfBoundsException: -1111494912 at qiniu.ip17mon.Locator.findIndexOffset(Locator.java:270) at qiniu.ip17mon.Locator.find(Locator.java:294) at qiniu.ip17mon.Locator.find(Locator.java:284)

完全不知道为啥.
