1. 新建Module

在这里插入图片描述

打开上一篇的mycrm项目，在当前项目File–>New–>Module
不勾选Create from archetype
路径和mycrm项目一致

2. 配置

2.1 pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

2.2 generator.properties

jdbc.driverLocation是你的本地仓库下面mysql的jar包

jdbc.driverLocation=C:/MySoftware/maven/repository_shine/mysql/mysql-connector-java/5.1.43/mysql-connector-java-5.1.43.jar
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.connectionURL=jdbc:mysql://localhost:3308/myssm?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

2.3 generatorConfig.xml

标签分析如下

引入数据库的配置文件

2. context标签

3. 配置数据库连接的<jdbcConnection>

4. 配置实体类存放路径

配置XML存放路径
dao存放路径和xml一样
