Java(31):Java对于jdbc对数据库的封装[2]

本文主要是介绍Java(31):Java对于jdbc对数据库的封装[2],对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

JDBC数据库操作的封装方法参考(之前写的这篇文章):Java(23):Java对于jdbc对数据库的封装[1]_fen_fen的专栏-CSDN博客

下面接着说的是,加上判断查询结果是否正确。

自己写的断言方法类:
断言类:DatabaseAssert.java

package com.ciphergateway.asserts;

import org.apache.commons.lang3.StringUtils;

import java.sql.SQLException;
import java.util.List;
import java.util.Map;


/**

public class DatabaseAssert {

    /**
     * 断言(入参Map_input)
     * @param listMaps_out
     * @param Map_input
     * @throws SQLException
     */
    public static int assertData(List<Map<String, Object>> listMaps_out,Map<String, String> Map_input){
        int num=0;
        for (Map<String, Object> map : listMaps_out) {
            for (String key : map.keySet()) {
                boolean flag=false;
                for (String key_input : Map_input.keySet()) {
                    //key值相同再对比value值
                    if(key.equals(key_input)){
                        //System.out.println(Map_input.get(key_input));
                        flag =StringUtils.endsWith(String.valueOf(map.get(key)), String.valueOf(Map_input.get(key_input)));
                        if (flag){
                            num += 1;
                        } else {
                            System.out.println("未找到匹配" + key);
                        }
                    }
                }
            }
        }
        return num;
    }

    /**
     * 断言(入参,标识符)
     * @param listMaps_out
     * @param cipher
     * @throws SQLException
     */
    public static int assertData(List<Map<String, Object>> listMaps_out,String cipher){
        int num=0;
        for (Map<String, Object> map : listMaps_out) {
            for (String key : map.keySet()) {
            boolean flag = false;
                if (key.equals("aoe_id") == false) {
                    //System.out.println(String.valueOf(map.get(key)));
                    //System.out.println(cipher);
                    flag = StringUtils.endsWith(String.valueOf(map.get(key)), cipher);
                    if (flag) {
                        num += 1;
                    } else {
                        System.out.println("未找到匹配" + key);
                    }
                }
            }

        }
        return num;
    }

}

调用示例二

数据库db.propeties

#mysql原库

driverClass =com.mysql.jdbc.Driver

url=jdbc:mysql://10.1.1.191:3306/aoe_auto?useSSL=false&useUnicode=yes&characterEncoding=UTF-8

userName=root

passWord=123456

断言调用:

int num= DatabaseAssert.assertData(listMaps_1,Map_input);

        Properties pro=Common.getProperty(filename);
