项目开发过程注意事项.docx

1、项目开发过程注意事项项目开发流程及注意事项一、开发环境（1）开发工具：eclipse（2）数据库：Oracle（3）导入代码格式化模板 1. java代码格式化模板导入java_formatter.xmlWindowPreferencesJavaCode StyleFormatterImport Profile 2. javascript代码格式化模板 导入javascript_formatter.xmlWindowPreferencesJavaScriptCode StyleFormatterImport Profile二、开发流程及注意事项（1）创建数据库1.建立表空间create tab

2、lespace tablespace_nameloggingdatafile D:oracleAdministratororadataorcltablespace_name.dbf size 200mautoextend onnext 10m maxsize unlimitedextent management local;2.建立数据库用户create user user_name identified by user_passworddefault tablespace tablespace_name;grant connect,resource to user_name; grant d

3、ba to user_name;3.为用户分配表空间revoke unlimited tablespace from user_name;alter user user_name quota unlimited on tablespace_name;4.创建项目开发所需表 create table table_name( column_name data_type)创建表也可以使用PL/SQL Developer 工具通过图形界面来创建表.(2)后台代码编写（SpringMVC+Mybatis）1.通过配置文件自动生成domain dao 和数据库映射文件配置marssrcmarsGenera

4、torConfig.xml文件 运行bulid-mybatis.xml文件 自动生成domain文件com.newheyd.practice.domain.Practice.java com.newheyd.practice.domain.PracticeExample.java 自动生成dao文件com.newheyd.practice.dao.PracticeMapper.javaPracticeMapper extends IMapper DAO接口继承IMapper接口 DAO中的接口实现类即可自动被mybatis注册自动生成数据库映射文件config.mapper.practice.

5、PracticeMapper.xmlserviceservice接口package com.newheyd.practice.service;public interface IPracticeService public int insert(Practice practice); public int update(Practice practice); public int delete(PracticeExample practiceExample); public List select(PracticeExample practiceExample); public int cou

6、nt(PracticeExample practiceExample); public Practice selectByPrimaryKey(Long i);./根据项目需求自行添加方法service接口实现类package com.newheyd.practice.service.impl;Servicepublic class PracticeServiceImpl extends BaseService implements IPracticeService Resource private PracticeMapper practiceMapper = null; Override

7、public int insert(Practice practice) return practiceMapper.insert(practice); Override public int update(Practice practice) int result = practiceMapper.updateByPrimaryKeySelective(practice); return result; Override public int delete(PracticeExample practiceExample) int result = practiceMapper.deleteB

8、yExample(practiceExample); return result; Override public List select(PracticeExample PracticeExample) return practiceMapper.selectByExample(PracticeExample); Override public int count(PracticeExample PracticeExample) int result = practiceMapper.countByExample(PracticeExample); return result; Overri

9、de public Practice selectByPrimaryKey(Long id) return practiceMapper.selectByPrimaryKey(id); controllerpackage com.newheyd.practice.controller;ControllerRequestMapping(/practice)public class practiceController extends BaseController Resource private final IPracticeService practiceService = null; Req

10、uestMapping(/list) ResponseBody public Result list(String testName,String testUser, Page page) PracticeExample practiceExample = new PracticeExample(); Criteria c = practiceExample.or(); if (testName != null) & !(.equals(testName) c.andTestNameLike(testName); if (testUser != null) & !(.equals(testUs

11、er) c.andTestUserLike(testUser); practiceExample.setOrderByClause(pra.id desc); practiceExample.setPage(page);/ 将分页类set入查询条件类，若不set则无分页 List list = practiceService.select(practiceExample); /System.out.println(list.size(); return new ListResult(page.getTotalRecord(), list); RequestMapping(/save) Resp

12、onseBody public Result save(RequestBody Practice practice) practice.setTestName(practice.getTestName(); practice.setTestUser(getCurrentUser().getName(); practice.setTestState(practice.getTestName(); practice.setTestDate(new Date(); practiceService.insert(practice); return new OperResult(true, 保存成功！)

13、; RequestMapping(/update) ResponseBody public Result update(RequestBody Practice practice) if (practice.getId() != null) practiceService.update(practice); return new OperResult(true, 更新成功！); RequestMapping(/delete) ResponseBody public Result delete(RequestBody List ids) throws MarsException Practice

14、Example practiceExample = new PracticeExample(); practiceExample.or().andIdIn(ids); practiceService.delete(practiceExample); return new OperResult(true, 删除成功！); 方法介绍list :列表查询，参数：查询条件，page对象save :添加保存，参数：新增的对象update:修改保存，参数：修改的对象delete:删除， 参数：删除的对象ID (3)前台代码编写（ExtJS4）1.modelExt.define(MARS.model.pra

15、ctice.PracticeModel, extend:Ext.data.Model, fields: name : id, type : Long, sortable : true , name : testName, type : string, sortable : true , name : testDate, type : Date, convert : function(value) var d = null; if (value != null) d = new Date(); d.setTime(value); return d; , name : testUser, type
