ssh框架中，工具类调用service层方法（参考https://www.cnblogs.com/l412382979/p/8526945.html）

代码如下：

package common.dataService;

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.womow.uap.bizc.IUapusersBizc;
import com.womow.vo.DBVo;

@Component//声明spring组件
public class DBTool {
	@Autowired
	private IUapusersBizc uapusersBizc;

	public static DBTool instance ;

	public void setUapusersBizc(IUapusersBizc uapusersBizc) {
		this.uapusersBizc = uapusersBizc;
	}

	@PostConstruct//通过@PostConstruct方法实现Bean初始化之前和销毁之前的自定义操作
	public void init(){//init方法是在构造函数执行之后 才执行的
		instance = this;
		instance.uapusersBizc = this.uapusersBizc;
	}

	public  DBVo getDBVoInfo(){
		DBVo dbVo = null;
		try {
			dbVo = uapusersBizc.findDBInfo();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return dbVo;
	}
}
