前端使用的技术：AdminLTE

• 简介：AdminLTE是一款建立在bootstrap和jquery之上的开源的模板主题工具，它提供了一系列响应的、可重复使用的组件，并内置了多个模板页面；同时自适应多种屏幕分辨率，兼容PC和移动端。通过AdminLTE，我们可以快速的创建一个响应式的Html5网站。AdminLTE框架在网页架构与设计上，有很大的辅助作用，尤其是前端架构设计师，用好AdminLTE 不但美观，而且可以免去写很大CSS与JS的工作量。
• 获取AdminLTE：

  现成的都在资料里

准备工作

数据库：Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Prod

Oracle 为每个项目创建单独user，每个用户有独立表空间，oracle数据存放在表空间下。

• 使用管理员连接到数据库，创建用户，并分配相应的权限

create user simth identified by simth;
grant connect, resource to simth;

• 使用simth用户连接数据库
  
  
• 创建产品表

CREATE TABLE product(id varchar2(32) default SYS_GUID() PRIMARY KEY,
                    productNum VARCHAR2(50) NOT NULL,
                    productName VARCHAR2(50),
                    cityName VARCHAR2(50),
                    DepartureTime timestamp,
                    productPrice Number,
                    productDesc VARCHAR2(500),
                    productStatus INT,
                    CONSTRAINT product UNIQUE (id, productNum));

• 插入数据

insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus)
values ('676C5BD1D35E429A8C2E114939C5685A', 'itcast-002', '北京三日游', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus)
values ('12B7ABF2A4C544568B0A7C69F36BF8B7', 'itcast-003', '上海五日游', '上海', to_timestamp('25-04-2018 14:30:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1800, '魔都我来了', 0);
insert into PRODUCT (id, productnum, productname, cityname, departuretime, productprice,productdesc, productstatus)
values ('9F71F01CB448476DAFB309AA6DF9497F', 'itcast-001', '北京三日游', '北京', to_timestamp('10-10-2018 10:10:00.000000', 'dd-mm-yyyy hh24:mi:ss.ff'), 1200, '不错的旅行', 1);

• MAVEN工程搭建

• 创建java和resources目录并标记
  
  
• hacker-ssm-dao(剩下的几个模块和dao模块的创建基本一样)
  
  
  
  
• 各模块创建完成后
  
  
• 编写产品实体类

package com.hacker.ssm.domain;

import java.util.Date;

public class Product {
    private String id; // 主键
    private String productNum; // 编号唯一
    private String productName; // 名称
    private String cityName; // 出发城市
    private Date departureTime; // 出发时间
    private String departureTimeStr;
    private double productPrice; // 产品价格
    private String productDesc; // 产品描述
    private Integer productStatus; // 状态 0 关闭 1 开启
    private String productStatusStr;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getProductNum() {
        return productNum;
    }

    public void setProductNum(String productNum) {
        this.productNum = productNum;
    }

    public String getProductName() {
        return productName;
    }

    public void setProductName(String productName) {
        this.productName = productName;
    }

    public String getCityName() {
        return cityName;
    }

    public void setCityName(String cityName) {
        this.cityName = cityName;
    }

    public Date getDepartureTime() {
        return departureTime;
    }

    public void setDepartureTime(Date departureTime) {
        this.departureTime = departureTime;
    }

    public String getDepartureTimeStr() {
        return departureTimeStr;
    }

    public void setDepartureTimeStr(String departureTimeStr) {
        this.departureTimeStr = departureTimeStr;
    }

    public double getProductPrice() {
        return productPrice;
    }

    public void setProductPrice(double productPrice) {
        this.productPrice = productPrice;
    }

    public String getProductDesc() {
        return productDesc;
    }

    public void setProductDesc(String productDesc) {
        this.productDesc = productDesc;
    }

    public Integer getProductStatus() {
        return productStatus;
    }

    public void setProductStatus(Integer productStatus) {
        this.productStatus = productStatus;
    }

    public String getProductStatusStr() {
        return productStatusStr;
    }

    public void setProductStatusStr(String productStatusStr) {
        this.productStatusStr = productStatusStr;
    }
}

• 编写持久层接口

package org.hacker.ssm.dao;

import org.apache.ibatis.annotations.Select;
import org.hacker.ssm.domain.Product;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 11:51
 */
public interface IProductDao {
    //查询所有的产品信息
    @Select("select * from product")
    public List<Product> findAll() throws Exception;
}

• 编写业务层接口

package org.hacker.ssm.service;

import org.hacker.ssm.domain.Product;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 10:46
 */
public interface IProductService {
    List<Product> findAll() throws Exception;
}

• 编写service实现类

package org.hacker.ssm.service.impl;

import org.hacker.ssm.dao.IProductDao;
import org.hacker.ssm.domain.Product;
import org.hacker.ssm.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 10:47
 */
@Service
@Transactional
public class ProductServiceImpl implements IProductService {
    @Autowired
    private IProductDao productDao;
    @Override
    public List<Product> findAll() throws Exception {
        return productDao.findAll();
    }
}

• 编写数据库配置文件db.properties

jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.url=jdbc:oracle:thin:@10.211.55.23:1521:orcl
jdbc.username=smith
jdbc.password=simth

• 编写Spring配置文件applicationContext.xml

SpringMVC环境搭建

配置springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"

    -->
    <aop:aspectj-autoproxy proxy-target-class="true"/>
</beans>

• 配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://xmlns.jcp.org/xml/ns/javaee"

    </context-param>

    <!-- 配置监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- 前端控制器（加载classpath:springmvc.xml 服务器启动创建servlet） -->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

• 导入log4j日志文件

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
# log4j.appender.LOGFILE=org.apache.log4j.FileAppender
# log4j.appender.LOGFILE.File=d:\axis.log
# log4j.appender.LOGFILE.Append=true
# log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
# log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

• 编写controller

package org.hacker.ssm.controller;

import org.hacker.ssm.service.IProductService;
import org.hacker.ssm.domain.Product;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 10:00
 */
@Controller
@RequestMapping("/product")
public class ProductController {
    @Autowired
    private IProductService productService;

    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception {
        ModelAndView mv = new ModelAndView();
        List<Product> ps = productService.findAll();
        mv.addObject("productList", ps);
        mv.setViewName("product-list1");
        return mv;
    }
}

• 运行查看情况
  
  clean->install 父工程 然后 clean->install web工程 如果出现异常就按照依赖关系clean->install
  
  使用mvn tomcant7:run,可以使用maven插件，也可以配置好点击
  
  
  
  
• 运行后，浏览器结果
  
  
• 导入插件，将pages里的静态文件换为jsp文件,导入到web工程中
  
  
• 修改index.jsp代码

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8"%>
<html>
<body>
<jsp:forward page="/pages/main.jsp"></jsp:forward>
</body>
</html>

• 运行项目，查看效果
  
  
• 产品管理现在可以查询数据库的产品
  
  
  
  

增加产品添加功能

• 往controller类里添加增加代码

package org.hacker.ssm.controller;

import org.hacker.ssm.service.IProductService;
import org.hacker.ssm.domain.Product;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 10:00
 */
@Controller
@RequestMapping("/product")
public class ProductController {
    @Autowired
    private IProductService productService;

    @RequestMapping("/save.do")
    public String save(Product product) {
        productService.save(product);
        return "redirect:finaAll.do";//重新回到list界面
    }

    @RequestMapping("/findAll.do")
    public ModelAndView findAll() throws Exception {
        ModelAndView mv = new ModelAndView();
        List<Product> ps = productService.findAll();
        mv.addObject("productList", ps);
        mv.setViewName("product-list1");
        return mv;
    }
}

• 修改IProductService代码

package org.hacker.ssm.service;

import org.hacker.ssm.domain.Product;

import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 10:46
 */
public interface IProductService {

    //从数据库查询所有商品
    List<Product> findAll() throws Exception;

    //添加商品
    void save(Product product);
}

• 修改ProductServiceImpl代码

package org.hacker.ssm.service.impl;

import org.hacker.ssm.dao.IProductDao;
import org.hacker.ssm.domain.Product;
import org.hacker.ssm.service.IProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;
/**
 * @author HackerStar
 * @create 2020-04-20 10:47
 */
@Service
@Transactional
public class ProductServiceImpl implements IProductService {
    @Autowired
    private IProductDao productDao;
    @Override
    public List<Product> findAll() throws Exception {
        return productDao.findAll();
    }

    @Override
    public void save(Product product) {
        productDao.save();
    }
}

• 修改IProductDao代码

package org.hacker.ssm.dao;

        import org.apache.ibatis.annotations.Insert;
        import org.apache.ibatis.annotations.Select;
        import org.hacker.ssm.domain.Product;

        import java.util.List;

/**
 * @author HackerStar
 * @create 2020-04-20 11:51
 */
public interface IProductDao {
    //查询所有的产品信息
    @Select("select * from product")
    public List<Product> findAll() throws Exception;

    //保存商品
    @Insert("insert into product(productNum,productName,cityName,departureTime,productPrice,productDesc,productStatus)" +
            "values(#{productNum},#{productName},#{cityName},#{departureTime},#{productPrice},#{productDesc},#{productStatus})")
    void save(Product product);
}

• 此时，运行项目，浏览器会出现400错误
  
  出现的异常：Field error in object 'product' on field 'departureTime': rejected value [2020-04-04 07:00]; typeMismatch.product.departureTime
• 添加工具类转换时间

package org.hacker.ssm.utils;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateUtils {

    //日期转换成字符串
    public static String date2String(Date date, String patt) {
        SimpleDateFormat sdf = new SimpleDateFormat(patt);
        String format = sdf.format(date);
        return format;
    }

    //字符串转换成日期
    public static Date string2Date(String str, String patt) throws ParseException {
        SimpleDateFormat sdf = new SimpleDateFormat(patt);
        Date parse = sdf.parse(str);
        return parse;
    }
}

• 修改domina代码，因为前端页面获取到的数据类型是String和数据库表中的时间类型是Date，所以需要转换
  
  这里是用Spring为我们提供的注解
  
  @DateTimeFormat将字符串转换为Date类型
  
  @JsonFormat将日期转换为string类型
  
  因为product-add.jsp获取出发时间时，使用input标签获取的是一个字符串，这里需要转换为Date类型，所以使用Spring提供的@DateTimeFormat注解
  
  
• 这里用到了utils包，根据不同的情况，给出不同的描述
  
  
  
  
• 结果
  
  
  
  

第一天的工作完毕
