SSM综合项目实战（TTSC） -- day01 项目介绍、工程搭建

一、配置环境

1、properties插件的安装

（1）、解压dropins.zip到eclipse目录下

（2）、重启Eclipse即可

二、项目架构

三、创建公共工程

1、为什么创建公共工程

        在Maven管理体系中需要将依赖进行统一管理，就需要用到taotao-parent父工程进行jar包的统一管理

        在开发过程中，需要将一些公用的类或者功能模块抽取出来，以达到重复使用的目的，所以需要创建taotao-common工程

2、搭建taotao-parent父工程环境

（1）、创建taotao-parent工程

（2）、导入jar包坐标

3、创建taotao-common公用工程

四、DUBBO介绍

五、搭建后台系统

1、如何搭建后台系统

        taotao-manager                   pom聚合工程的父工程，负责把所有子工程聚合在一起

        taotao-manager-pojo           jar聚合工程的子工程，javaBean

        taotao-manager-mapper          jar             聚合工程的子工程，DAO层

        taotao-manager-interface         jar           聚合工程的子工程，业务处理层的接口

        taotao-manager-service          war聚合工程的子工程，业务处理层

        taotao-manager-controller     war单独的工程，页面控制层

2、搭建taotao-manager聚合工程的父工程环境

3、搭建taotao-pojo、taotao-mapper、taotao-interface、taotao-service等子工程，都为taotao-manager的module

八、导入后台管理系统静态页面

1、导入静态页面资源

九、启动聚合工程taotao-manager和taotao-manager-web

1、打包聚合工程

2、添加源码

3、启动项目

十、使用Dubbo

1、创建测试接口和Mapper

package com.taotao.manager.mapper.test;public interface TestMapper {/** * 从数据库获取当前时间 */public String queryDate();}

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapperPUBLIC "-//mybatis.org//DTD Mapper 3.0//EN""http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.taotao.manager.mapper.test.TestMapper"><!-- 获取数据库当前时间 --><select id="queryDate" resultType="string">SELECT NOW()</select></mapper>

2、创建测试Service

package com.taotao.manager.service.test;public interface TestService {/** * 查询当前数据库时间 * @return */public String queryDate();}

package com.taotao.manager.service.test.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.taotao.manager.mapper.test.TestMapper;import com.taotao.manager.service.test.TestService;@Servicepublic class TestServiceImpl implements TestService {@Autowiredprivate TestMapper mapper;/** * 查询当前数据库时间 */public String queryDate() {return mapper.queryDate();}}

3、创建测试Controller

package com.taotao.manager.controller.test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import com.taotao.manager.service.test.TestService;@Controllerpublic class TestController {@Autowiredprivate TestService service;@RequestMapping("/queryDate.do")@ResponseBodypublic String queryDate(){return service.queryDate();}}

4、编写配置文件  --  注册服务

<!-- 配置dubbo --><!-- 提供方应用信息，用于计算依赖关系 --><dubbo:application name="taotao-manager-service" /><!-- 使用multicast广播注册中心暴露服务地址 --><dubbo:registry address="multicast://224.5.6.7:1234" /><!-- 用dubbo协议在20880端口暴露服务 --><dubbo:protocol name="dubbo" port="20880" /><!-- 声明需要暴露的服务接口 --><dubbo:service interface="com.taotao.manager.service.test.TestService"ref="testServiceImpl" />

5、编写配置文件  --  调用服务 

<!-- 配置dubbo服务 --><dubbo:application name="taotao-manager-web" /><!-- 使用广播 --><dubbo:registry address="multicast://224.5.6.7:1234" /><!-- 声明要调用的服务，timeout是设置连接超时最长时间,如果不设置，超时时间默认是3秒 --><dubbo:reference interface="com.taotao.manager.service.test.TestService"id="testService" timeout="1000000" />
