Java读取.properties配置文件

1.通过PropertiesLoaderUtils类来读取

import org.springframework.core.io.support.PropertiesLoaderUtils;

Properties properties = PropertiesLoaderUtils.loadAllProperties("test.properties");
String test = properties.getProperty("test");
System.out.println("properties.test:"+test);

2.通过 java.util.ResourceBundle 类来读取

//不需要加.properties后缀名，只需要文件名即可
//test. properties配置文件在com.test.config下面，则wei com/test/config/test
ResourceBundle resource = ResourceBundle.getBundle("test");
String test = resource.getString("test");
System.out.println("resource.test:"+test);
