步骤1：在项目中新建com.bstek.dorado.sample.standardlesson.service包，用于集中放置项目中需要的service。
步骤2：在service包中新建SystemInfoService.java，代码如下：
package com.bstek.dorado.sample.standardlesson.service;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Properties;
import org.springframework.stereotype.Component;
import com.bstek.dorado.annotation.Expose;
import com.bstek.dorado.core.DoradoAbout;
@Component
public class SystemInfoService {
@Expose
public Properties getSystemInfo() {
Properties info = new Properties();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 hh:mm:ss");
info.setProperty("product", DoradoAbout.getProductTitle());
info.setProperty("vendor", DoradoAbout.getVendor());
info.setProperty("version", DoradoAbout.getVersion());
info.setProperty("time", sdf.format(new Date()));
return info;
}
}
