import java.util.HashMap;
import java.util.Map;

import org.apache.commons.beanutils.BeanUtils;

import com.dss.mci.sys.entity.User;

public class Test {
    public static void main(String[] args) throws Exception {
        // BeanUtils.populate(user,keyValues); map->bean
        Map<String, String> keyValues = new HashMap<>();
        keyValues.put("userAccount", "ddd");
        User user = new User();

        // 将Map转化为User
        BeanUtils.populate(user, keyValues);
        System.out.println(user.getUserAccount());

        Map<String, String> map = new HashMap<>();
        // bean->map
        map = BeanUtils.describe(user);
        System.out.println(map.get("userAccount"));
