sping java代碼中讀取配置文件信息

        Resource resource = new ClassPathResource("conf/configInfo.properties");

        Properties props = PropertiesLoaderUtils.loadProperties(resource);

        System.out.println(props.get("email.host"));

---configInfo.properties配置文件信息

email.host = www.94gleaner.com

email.port = xxx

email.username = gleaner

email.password = xxx

email.sendFrom = 94gleaner@94gleaner.com

@Component("configInfo")

public class ConfigInfo {

    @Value("${email.host}")

    private String host;

    @Value("${email.port}")

    private String port;

    public String getHost() {

        return host;

    }

    public void setHost(String host) {

        this.host = host;

    }

    public String getPort() {

        return port;

    }

    public void setPort(String port) {

        this.port = port;

    }

}
