The configuration file analysis and loading of the PureConfig framework in the Java library library library

PureConfig is a Java library for parsing and loading configuration files.The configuration file is a set of parameters and values used during the program. It can be parsed into an object in the Java class library through PureConfig. PureConfig supports a variety of configuration file formats, such as HUMAN-OPTIMIZED Config Object Notation), JSON, Java attribute files, and YAML.You can choose a suitable file format according to specific needs. The process of using PureConfig parsing the configuration file is as follows: 1. Introduce PureConfig dependencies: implementation 'com.github.pureconfig:pureconfig:0.14.0' 2. Create a Java class to store the parameters and values of the configuration file: public class AppConfig { public String appName; public int port; public List<String> servers; } 3. Create a configuration file, such as `application.conf`: hocon app { name = "MyApp" port = 8080 servers = ["server1", "server2", "server3"] } 4. Use PureConfig to parse the configuration file: ConfigObject config = ConfigFactory.parseFile(new File("application.conf")); AppConfig appConfig = PureConfig.loadConfigOrThrow(config, AppConfig.class); Through the above steps, the parameters and values in the configuration file will be parsed as the `appconfig` object.You can obtain the corresponding value in the configuration file by accessing the attributes of the `appconfig` object. The main advantage of PureConfig is that it provides a type of security configuration file analysis.It can automatically convert the value in the configuration file to the correct Java type, avoiding the tedious operation of manual analysis and type conversion. Note: The above code is only an example. The specific configuration files and object structures need to be adjusted according to the actual situation.
