该系列文章主要是对 hutool 工具类的介绍，详情可以参考

了解过 Spring 的对Java 的配置文件肯定不陌生，从最开始的 xml，到之后 properties，yml

properties 不支持中文

xml 配置太过繁琐

hutool 提供了一种自定义的 setting 配置格式

1 Props

@Test
public void testProp() {
    Props props = PropsUtil.get("setting/test.properties");
    ConfigProperties configProperties = props.toBean(ConfigProperties.class, "mail");
    Console.log(configProperties);
}

#Simple properties
mail.host=mailer@mail.com
mail.port=9000
mail.from=mailer@mail.com
#List properties
mail.defaultRecipients[0]=admin@mail.com
mail.defaultRecipients[1]=owner@mail.com
#Map Properties
mail.additionalHeaders.redelivery=true
mail.additionalHeaders.secure=true
#Object properties
mail.credentials.username=john
mail.credentials.password=password
mail.credentials.authMethod=SHA1
# ignore properties
mail.ignore.filed=balabala

2 setting

@Test
public void testSetting() {
    Setting setting = SettingUtil.get("setting/test.setting");
    JdbcConfig jdbcConfig = setting.toBean("demo", JdbcConfig.class);
    Console.log(jdbcConfig);
}

@Test
public void testStoreSetting() {
    Setting setting = SettingUtil.get("setting/out/out.setting");
    setting.setByGroup("key1", "group1", "value1");
    setting.setByGroup("key2", "group1", "value2");
    setting.setByGroup("key1", "group2", "value1");
    setting.setByGroup("key2", "group2", "value2");
    setting.store();
}

url = jdbc:mysql://127.0.0.1:3306/test
#用户名，必须
user = root${driver}
user2 = root${demo.driver}
