第04项目：淘淘商城(SpringMVC+Spring+Mybatis) 的学习实践总结【第一天】

开发环境：

Eclipse IDE for Enterprise Java Developers.

Version: 2019-09 R (4.13.0)
Build id: 20190917-1200
OS: Windows 10, v.10.0, x86_64 / win32

Java version: 1.8.0

MySQL Datebase：5.6.45

01.第一天（项目介绍，搭建maven工程）

---

4 后台管理系统工程搭建

4.3  父工程的搭建

父工程应该是一个pom工程。在父工程中定义依赖的jar包的版本信息。Maven插件的版本。

4.3.3  修改pom文件

父工程集中定义依赖版本的

pom.xml

DAO层的maven一键打包编译build会自动过滤掉忽视src/main/java目录及子目录的不是以 .java作为拓展名的文件。因此后面使用mybatis的逆向工程生成的mapper.xml文件会扫描不到，需要在

taotao-manager-mapper的pom.xml

添加<build>标签的编译过滤器配置

5  测试maven工程

taotao-manager-web

5.1  运行的工程

要运行工程，需要运行聚合工程也就是taotao-manager。

5.2  Tomcat插件

在taotao-manager工程的pom文件中添加如下内容：

    <build>

        <!-- 配置插件 -->

        <plugins>

            <plugin>

                <groupId>org.apache.tomcat.maven</groupId>

                <artifactId>tomcat7-maven-plugin</artifactId>

                <configuration>

                    <port>8080</port>

                    <path>/</path>

                </configuration>

            </plugin>

        </plugins>

    </build>

5.3  启动工程

使用maven命令：

clean tomcat7:run

注意：

1、需要把taotao-parent工程安装到本地仓库。Run As：Maven Install

2、需要把taotao-common安装到本地仓库。

---

maven远程中央仓库JSP相关的artifactId和视频课中的有出入，需要在taotao-parent和taotao-manager-web的pom.xml里作出更改：

    <!-- 集中定义依赖版本号 -->

    <properties>

        <jstl.version>1.2</jstl.version>

        <servlet-api.version>3.1.0</servlet-api.version>

        <jsp-api.version>2.2</jsp-api.version>

    </properties>

        <!-- JSP相关 -->

        <dependency>

            <groupId>jstl</groupId>

            <artifactId>jstl</artifactId>

        </dependency>

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>javax.servlet-api</artifactId>

            <scope>provided</scope>

        </dependency>

        <dependency>

            <groupId>javax.servlet.jsp</groupId>

            <artifactId>jsp-api</artifactId>
