springboot2 指定ip

springboot2 指定ip

1、问题回顾

按照ip2region项目的官方集成到springboot项目后，运行测试一切都ok，没有任何问题。但是当项目打成可执行的jar包后再运行，却显示找不到ip2region.db，无法找到资源文件的错误。异常代码如下：

java.io.FileNotFoundException: class path resource [ip2region/ip2region.db] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/app.jar!/BOOT-INF/classes!/ip2region/ip2region.db

2、解决办法

将ip2region.db文件放到本地目录，然后直接读取本地文件进行ip解析，代码如下：

public static String getCityInfo(String ip) {

DbSearcher searcher = null;

try {

String dbPath = Profile() + "ip2region/ip2region.db";

//String dbPath = "f:/profile/ip2region/ip2region.db"; //本地测试使用地址

File file = new File(dbPath);

if (ists()) {

DbConfig config = new DbConfig();

searcher = new DbSearcher(config, Path());

Method method = Class().getMethod("btreeSearch", String.class);

if (!Util.isIpAddress(ip)) {

}

DataBlock dataBlock = (DataBlock) method.invoke(searcher, ip);

Region();

}

} catch (Exception e) {

}

return "XX XX";

}

注&#Profile()是配置的本地文件存储路径
