一个适用于json配置的配置管理构件
- 支持动态加载配置文件
- 可变的配置文件位置
- 可直接配置成Java对象
- 可以根据键读值
- 支持链式调用，可以读取嵌套配置
- jdk >= 1.5
- 配置文件格式:json
File -> project structure -> Libraries
- First, new a Config object,
Config config = new Config();- Second, load json configuration file,
config.readFile("config/conf.json");- Third, invoke relevant API.
//get nested configuration
Config getConf(String key);
//get String value of key
String getString(String key);
//get int value of key
int getInt(String key);
//get float value of key
int getFloat(String key);
//get String array value of key
String[] getStringArray(String key)
//directly convert to a Java bean
<T> T toObj(Class<T> t);{
"server":{
"host":"localhost",
"port":8080,
"MaxMsgNumber":100,
"MaxMsgNumberPerSec":5
},
"strArray":["aa","bb"]
}public class Configuration {
private String host;
private int port;
private int maxMsgNumber;
private int maxMsgNumberPerSec;
//setters and getters
...import conf.Config;
Config config = new Config();
config.readFile("config/conf.json");
//convert to Confihuration class
Configuration configuration = config.getConf("server").toObj(Configuration.class);
//get String value-"host"
String host = config.getConf("server").getString("host");
//get String Array
String[] result = config.getStringArray("strArray");
