当使用BeanListHandler时只需加上下面代码即可

QueryRunner runner=new QueryRunner(druidDataSource);
//开启驼峰映射
BeanProcessor bean = new GenerousBeanProcessor();
RowProcessor processor = new BasicRowProcessor(bean);
String sql="";
//此处Area传入列表需要的泛型
List<Area> list=runner.query(sql,new BeanListHandler<Area>(Area.class,processor))

当需要返回结果为List<Map<String,String>>时就需要我们自己写一个Handler了

此处贴出我自己写的类

import org.apache.commons.dbutils.handlers.MapListHandler;

import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Map;

/**

 * @author hang.zhong

public class CamelMapListHandler extends MapListHandler {
    @Override
    protected Map<String, Object> handleRow(ResultSet rs) throws SQLException {
        Map<String, Object> result = new HashMap<>();
        ResultSetMetaData rsmd = rs.getMetaData();
        int cols = rsmd.getColumnCount();

        for(int i = 1; i <= cols; ++i) {
            String columnName = rsmd.getColumnLabel(i);
            if (null == columnName || 0 == columnName.length()) {
                columnName = rsmd.getColumnName(i);
            }
　　　　　　　//此处CamelUndelineUtil为一个下划线转驼峰的工具，这种工具很简单，我就不贴出来了
            result.put(CamelUndelineUtil.camel(columnName), rs.getObject(i));
        }
        return result;
    }
}

使用时

QueryRunner runner=new QueryRunner(druidDataSource);

String sql="";
List<Map<String,Object>> list=runner.query(sql,new CamelMapListHandler(),null)
