idea自动封装方法

例如

package com.utils;

import java.lang.reflect.Field;
import java.sql.*;
import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;

/**

public class DBUtils {
    private static ResourceBundle bundle=ResourceBundle.getBundle("jdbc");
    private static String driver=bundle.getString("jdbc.driver");
    private static String url=bundle.getString("jdbc.url");
    private static String username=bundle.getString("jdbc.username");
    private static String password=bundle.getString("jdbc.password");

    static{
        try {
            Class.forName(driver);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }

    //通用查询多个
    public static  List selectList(Class clazz, String sql, Object...args){
        Connection conn=null;
        PreparedStatement ps=null;
        ResultSet rs=null;

        try {
            conn=DBUtils.getConnection();
            ps=conn.prepareStatement(sql);

            for(int i=0;i list=new ArrayList<>();
            while(rs.next()){
                T t = clazz.newInstance();
                for(int i=0;i T selectOne(Class clazz,String sql,Object...args){
        Connection conn=null;
        PreparedStatement ps=null;
        ResultSet rs=null;

        try {
            conn=DBUtils.getConnection();
            ps=conn.prepareStatement(sql);

            for(int i=0;i

这段代码中

可以提取出来作为独立的一个方法
