properties文件操作

properties文件操作类

可以使用java.util.Properties读取.properties文件中的内容

import java.io.InputStream;
import java.util.Properties;

import org.apache.commons.lang.exception.ExceptionUtils;
import org.springframework.core.io.ClassPathResource;

/**properties配置文件读取*/

public class ConfigReader
{
    // 文件路径
    private static final String file = "sql.properties";
    
    //配置保存类
    private static final Properties props = new Properties();
    
    static
    {
        ClassPathResource resource = new ClassPathResource(file);
        InputStream inputStream = null;
        try
        {
            inputStream = resource.getInputStream();
            props.load(inputStream);
        }
        catch (Exception e)
        {
           //打印错误日志
        }
        finally
        {
            closeQuietly(inputStream);
        }
    }
    
    /**
     * 根据名字获取
     */
    public static String getProperty(String propertyName)
    {
        return props.getProperty(propertyName);
    }
    /*
    *资源关闭
    */
    public static void closeQuietly(Closeable closeable)
    {
        if (null != closeable)
        {
            try
            {
                closeable.close();
            }
            catch (Exception e)
            {
                
            }
        }
    }
}

config.properties文件内容

name=zqq
age=18

使用

ConfigReader.getProperty("name");
