读取此key.properties文件

代码实现

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;public class PropertyUtils {private static final Properties properties = new Properties();static {try (InputStream resourceAsStream = PropertyUtils.class.getResourceAsStream("/key.properties")) {properties.load(resourceAsStream);} catch (IOException e) {throw new RuntimeException(e);}}public static String getKey() {return properties.getProperty("key");}public static String getValue() {return properties.getProperty("value");}
}

UT测试

import org.junit.Assert;
import org.junit.Test;public class PropertyUtilsTest {@Testpublic void testPropertyUtils() {Assert.assertEquals("key", PropertyUtils.getKey());Assert.assertEquals("value", PropertyUtils.getValue());}
}
