分享在java中如何读取配置文件？下面就为大家介绍一下，代码如下：

public class PropertyUtil {
    public static final Properties PROP = new Properties();

    /**
     * 读取配置文件的内容（key，value）
     *
     * @param key
     * @return key对应的value
     */
    public static String get(String key) {
        if (PROP.isEmpty()) {
            try {
                InputStream in = PropertyUtil.class.getResourceAsStream("/config.properties");
                PROP.load(in);
                in.close();
            } catch (Exception e) {}
        }
        return PROP.getProperty(key);
    }
}

• 在resources文件下新建config.properties文件

websitepath=E:\\code\\landtax\\landtax\\
standardcondition=\"C_CD\"<=0.2
filePathTDQS=D:\\webspace\\import\\\u571F\u5730\u6743\u5C5E\u4FE1\u606F.xlsx
