MySQL使用存储过程
题目：根据图片所给的表做一个简单的能实现增删查改的项目
（要求：增删改要有存储过程，查询要用到视图查询）
项目名：ConsPrc
工具：MyEclipse
数据库：MySQL
存储过程：
Oracle：Oracle存储过程
MySQL：下面会讲
1、创表
c_cons_prc表.sql
CREATE DATABASE `work`;
USE `work`;
DROP TABLE IF EXISTS `c_cons_prc`;
CREATE TABLE `c_cons_prc` (
`tariff_id` INT(16) NOT NULL AUTO_INCREMENT COMMENT '用户电价标识',
`sp_id` INT(16) DEFAULT NULL COMMENT '受电点标识',
`cons_id` INT(16) DEFAULT NULL COMMENT '用户标识',
`pf_std_code` VARCHAR(20) DEFAULT NULL COMMENT '功率因数标准',
`trade_code` VARCHAR(20) DEFAULT NULL COMMENT '电价行业类别',
`prc_code` VARCHAR(20) DEFAULT NULL COMMENT '电价码',
`ts_flag` VARCHAR(20) DEFAULT NULL COMMENT '是否执行峰谷标志',
`fix_ratio` FLOAT DEFAULT NULL COMMENT '固定力率',
PRIMARY KEY (`tariff_id`)
) ENGINE=INNODB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;
INSERT INTO `c_cons_prc`(`tariff_id`,`sp_id`,`cons_id`,`pf_std_code`,`trade_code`,`prc_code`,`ts_flag`,`fix_ratio`)
VALUES (1,1001,123456,'1001','生活用电','1001','1001',1001),
(2,1002,111111,'1002','生活用电','1002','1002',1002),
(4,1004,1004,'1004','商业用电','1004','1004',1004),
(5,1005,1005,'1005','生活用电','1005','1005',1005),
(6,1006,1006,'1006','商业用电','1006','否',1006),
(7,1007,1007,'1007','生活用电','1007','是',1007),
(8,1008,1008,'1008','商业用电','1008','1008',1008),
(9,1009,1009,'1009','商业用电','1009','1009',1009),
(10,1010,1010,'1010','生活用电','1010','否',1010);
2、项目结构
3、导入jar包
jar包导入到上方的lib文件夹中
4、实体类pojo
C_Cons_Prc.java
因为只有一张表，所以我将视图的字段写的和原表一模一样，这样方便好记
package com.pojo;
/**
* 用户电价表
* @author Administrator
*
*/
public class C_Cons_Prc {
private int tariff_id;//用户电价标识
private int sp_id;//受电点标识
private int cons_id;//用户标识
private String pf_std_code;//功率因数标准
private String trade_code;//电价行业类别
private String prc_code;//电价码
private String ts_flag;//是否执行峰谷标志
private float fix_ratio;//固定力率
public int getTariff_id() {
return tariff_id;
}
public void setTariff_id(int tariff_id) {
this.tariff_id = tariff_id;
}
public int getSp_id() {
return sp_id;
}
public void setSp_id(int sp_id) {
this.sp_id = sp_id;
}
public int getCons_id() {
return cons_id;
}
public void setCons_id(int cons_id) {
this.cons_id = cons_id;
}
public String getPf_std_code() {
return pf_std_code;
}
public void setPf_std_code(String pf_std_code) {
this.pf_std_code = pf_std_code;
}
public String getTrade_code() {
return trade_code;
}
public void setTrade_code(String trade_code) {
this.trade_code = trade_code;
}
public String getPrc_code() {
return prc_code;
}
public void setPrc_code(String prc_code) {
this.prc_code = prc_code;
}
public String getTs_flag() {
return ts_flag;
}
public void setTs_flag(String ts_flag) {
this.ts_flag = ts_flag;
}
public float getFix_ratio() {
return fix_ratio;
}
public void setFix_ratio(float fix_ratio) {
this.fix_ratio = fix_ratio;
}
}
5、dao层
C_Cons_PrcMapper.java
package com.dao;
import java.util.List;
import org.apache.ibatis.annotations.Param;
import com.pojo.C_Cons_Prc;
public interface C_Cons_PrcMapper {
public List findAll();
public int findCount();
public List findList(@Param("currPage")int currPage,
@Param("pageSize")int pageSize);
public C_Cons_Prc findById(int tariff_id);
public int addC_Cons_Prc(C_Cons_Prc p);
public int delC_Cons_Prc(int tariff_id);
public int updC_Cons_Prc(C_Cons_Prc p);
public List findByCondition(String trade_code);
}
C_Cons_PrcMapper.xml
{call addC_Cons_Prc(
#{tariff_id,mode=OUT,jdbcType=INTEGER},#{sp_id,mode=IN},
#{cons_id,mode=IN},#{pf_std_code,mode=IN},#{trade_code,mode=IN},
#{prc_code,mode=IN},#{ts_flag,mode=IN},#{fix_ratio,mode=IN}
)}
{call delC_Cons_Prc(
#{tariff_id,mode=IN}
)}
{call updC_Cons_Prc(
#{tariff_id,mode=IN},#{sp_id,mode=IN},#{cons_id,mode=IN},#{pf_std_code,mode=IN},
#{trade_code,mode=IN},#{prc_code,mode=IN},#{ts_flag,mode=IN},#{fix_ratio,mode=IN}
)}
6、controller
C_Cons_PrcController.java
package com.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.pojo.C_Cons_Prc;
import com.service.C_Cons_PrcService;
@Controller
@RequestMapping("/pc")
public class C_Cons_PrcController {
@Autowired
private C_Cons_PrcService objService;
@RequestMapping("/index")
public String index(Model model){
return "index";
}
@RequestMapping("/add")//显示添加页面
public String addShow(){
return "add";
}
@RequestMapping("/addCons.do")//显示添加页面
@ResponseBody//ajax的方式
public String addP(C_Cons_Prc p){
int res = objService.addC_Cons_Prc(p);
return JSON.toJSONString(res);
}
@RequestMapping("/findAll")
public String findAll(C_Cons_Prc p){
List list = objService.findAll();
return "index";
}
@RequestMapping(value="/findCons.do")
@ResponseBody
public Object findPerpay(@RequestParam(value="page",required=false)Integer currPage,
@RequestParam(value="limit",required=false)Integer pageSize){
System.out.println("findCons");
if (currPage==null) {
currPage=1;
}
if (pageSize==null) {
pageSize=10;
}
int limitOne=(currPage-1)*pageSize;
//记录数
List list = objService.findList(limitOne, pageSize);
//总记录数
int count=objService.findCount();
System.out.println(count);
String strjson=JSON.toJSONString(list);
String json = "{\"code\":0,\"msg\":\"\",\"count\":" + count + ",\"data\":" + strjson + "}";
System.out.println(JSONObject.toJSON(list));
return JSONObject.toJSON(list);
}
@RequestMapping("/del")
@ResponseBody
public String del(Integer id){
int res = objService.delC_Cons_Prc(id);
return JSON.toJSONString(res);
}
@RequestMapping("/update")
public String update(){
return "update";
}
@RequestMapping("/updSel")
public String updSel(Integer id,Model model){
System.out.println(id);
C_Cons_Prc cons = objService.findById(id);
model.addAttribute("cons",cons);
return "update";
}
@RequestMapping("/updCons")
@ResponseBody
public String updCons(C_Cons_Prc cons){
int res = objService.updC_Cons_Prc(cons);
System.out.println(JSON.toJSONString(res));
return JSON.toJSONString(res);
}
//条件查询
@RequestMapping("/findByCondition")
@ResponseBody
public String findByCondition(String trade_code,Model model){
List list = objService.findByCondition(trade_code);
return JSON.toJSONString(list);
}
}
7、jsp页面
查询页面：index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
查询
用户电价信息
电价行业类别:
用户电价标识
受电点标识
用户标识
功率因数标准
电价行业类别
电价码

固定力率
操作
添加页面：add.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

题外话
第一次在博客上写一整个练习项目，写的不好勿喷，还有因为老师没有布置分页，所以controller的分页我也没去实现，各位大佬还是自行解决吧，溜了溜了
