一、创建远程仓库 mp-generator
仓库地址:https://gitee.com/zhuang-rui-boy/mp-generator.git
二、创建springboot项目
1、从远程仓库拉取项目
2、创建模块
如果是web项目的话:
三、修改pom.xml并引入依赖
为了方便springboot项目的依赖版本的管理,将pom.xml文件进行修改
1、起初的pom.xml文件
<<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.6.6</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<groupId>com.zhuang.mall</groupId>
<artifactId>mall-product</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>mall-product</name>
<description>商城的商品服务</description>
<properties>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
删掉parent模块,增加以下的配置:
2、properties
模块中添加<spring-boot.version>2.6.6</spring-boot.version>
<!-- <properties>里增加springboot的版本 -->
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<spring-boot.version>2.6.6</spring-boot.version>
</properties>
3、 增加的dependencyManagement
模块
<!-- 增加的<dependencyManagement>对springboot的所有依赖版本进行控制,实际上与<parent>作用是一样的,只是这种更加方便-->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
4、增加插件
<!-- 增加maven-compiler-plugin插件,防止对java程序的编译版本不是jdk1.8,可能变成jdk1.5版本-->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
5、引入单元测试
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
5、修改后的pom.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<!-- <parent>-->
<!-- <groupId>org.springframework.boot</groupId>-->
<!-- <artifactId>spring-boot-starter-parent</artifactId>-->
<!-- <version>2.6.6</version>-->
<!-- <relativePath/> <!– lookup parent from repository –>-->
<!-- </parent>-->
<groupId>com.zhuang.mall</groupId>
<artifactId>mall-product</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>mall-product</name>
<description>商城的商品服务</description>
<properties>
<java.version>1.8</java.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<spring-boot.version>2.6.6</spring-boot.version>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<!-- 增加的<dependencyManagement>对springboot的所有依赖版本进行控制-->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
四、修改父项目
点击右侧的maven,可以看出没有父项目mp-generator
,原因是没有pom.xml
文件。
1、父项目添加pom.xml文件
首先复制子模块的pom.xml文件,粘贴到父项目中。
2、修改pom.xml文件
删除多余的模块、修改父项目的名称、打包方式以及引入子模块
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.zhuang.mpgenerator</groupId>
<artifactId>mp-generator</artifactId>
<version>0.0.1-SNAPSHOT</version>
<name>mp-generator</name>
<description>商城的聚合服务</description>
<!-- 打包方式为pom-->
<packaging>pom</packaging>
<!-- 将子模块引入-->
<modules>
<module>mall-product</module>
</modules>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.5.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
3、在maven中引入父项目
点击右侧maven中的”+
“号,找到父项目mp-generator的配pom.xml置文件,并打开。
可以看出引进了父项目并定义为root,管理子模块。
五、添加renren-generator与renren-fast模块
进入gitee官网
,搜索人人开源,找到人人开源/renren-generator
与人人开源/renren-fast
下载下来,复制粘贴到项目中。并在父项目的pom.xml文件中,添加module为renren-generator和renren-fast。
六、添加mybatis-plus依赖与mysql数据库驱动
1、在mall-product
模块中的pom.xml
文件中,添加依赖
<!-- mybatis-plus--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>3.2.0</version> </dependency> <!-- 导入mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.25</version> </dependency>
2、在resource
下新建application.yml
文件
server:
port: 1010
spring:
datasource:
username: root
password: 1234
url: jdbc:mysql://10.211.55.4:3306/gulimall_pms
driver-class-name: com.mysql.cj.jdbc.Driver
application:
name: mall-product
mybatis-plus:
mapper-locations: classpath*:/mapper/**/*.xml
global-config:
db-config:
id-type: auto
七、添加依赖出错!!!
注意:本人一开始配置时driver-class-name: com.mysql.cj.jdbc.Driver
爆红
提示Cannot resolve class or package 'mysql'
。
遇到上述问题的解决方法:
点击File-Project Structure
,查看里面的Moduls
中mall-product
的依赖,如下图
情形一:
如果里面没有mysql依赖,说明没有导入jar包,就尝试点击右侧maven
的reload project
,如果还是没有,就看下面Libraries
里有没有mysql jar包
。如果没有的话,就将mysql jar包
从mave
n仓库里导入到Libraries
中。
如下图,我遇到的问题是Libraries里有mysql的jar包的
那么我们就在Modules的dependencies里点击下方的”+”,选择Libraries里的mysql jar包。就好了。
情形二:
可能Modules里有mysql的jar包,它的scope
为Runtime
,那么需要将其改为Compile,就OK了。
八、更改renren-generator的配置文件
首先,打开renren-generator的application.properties文件,
添加需要代码生成的包和数据库中的表。
修改的地方为:
#修改1
mainPath=com.zhuang
#\u5305\u540D
#修改2
package=com.zhuang.mall
moduleName=product
#\u4F5C\u8005
#修改3
author=mrzhuang
#Email
#修改4
email=862627527@qq.com
#\u8868\u524D\u7F00(\u7C7B\u540D\u4E0D\u4F1A\u5305\u542B\u8868\u524D\u7F00)
#数据库中表的前缀
#修改5
tablePrefix=pms_
然后,打开renren-generator
的application.yml
文件
添加mysql的数据源配置,端口port为81。
server:
port: 81
# mysql
spring:
datasource:
type: com.alibaba.druid.pool.DruidDataSource
#MySQL配置
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://10.211.55.4:3306/gulimall_pms?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
username: root
password: 1234
注意:为了避免mall-product项目里shiro依赖没有引入的影响,两种方案:第一就是引入shiro的依赖包,第二种方法就是在renren-generator的src/main/resources/template/Controller.java.vm里,将import 的shiro删除,并将@RequiresPermissions注释掉。
九、新建mall-common的maven模块
新建的mall-common
模块的里面需要的包都在renrne-fast
的src/main/java/io/renren/common
下。
新建一个mall-common
的maven项目
,并先将renren-fast
中的src/main/java/io/renren/common/utils下的R
、PageUtils
、Query
和Constant
类工具类复制粘贴到
mall-common的src/main/java/com/zhuang/common/utils下,然后按着爆红的提示,从renren-fast中copy相应的包和类。
十、运行renren-generator项目
1、访问http://localhost:81
可以看出,运行成功,并成功连接上了mysql数据库的表。
2、生成代码
将表全部选中,点击生成代码按钮。会生成一个名为renren的压缩包,进行解压,将其中的main文件夹复制粘贴到mall-product项目里。
粘贴后:
十一、测试
进入mall-product
的src/main/java/com/zhuang/mall/product/controller/CategoryController.java类下
浏览器上执行http://localhost:1010/product/category/list
结果如下:
{"msg":"success","code":200,"page":{"totalCount":0,"pageSize":10,"totalPage":0,"currPage":1,"list":[{"catId":1,"name":"图书、音像、电子书刊","parentCid":0,"catLevel":1,"showStatus":1,"sort":0,"icon":"WE","productUnit":"W","productCount":0},{"catId":2,"name":"手机","parentCid":0,"catLevel":1,"showStatus":1,"sort":2,"icon":null,"productUnit":null,"productCount":0},{"catId":3,"name":"家用电器","parentCid":0,"catLevel":1,"showStatus":1,"sort":3,"icon":null,"productUnit":null,"productCount":0},{"catId":4,"name":"数码","parentCid":0,"catLevel":1,"showStatus":1,"sort":4,"icon":null,"productUnit":null,"productCount":0},{"catId":5,"name":"家居家装","parentCid":0,"catLevel":1,"showStatus":1,"sort":5,"icon":null,"productUnit":null,"productCount":0},{"catId":6,"name":"电脑办公","parentCid":0,"catLevel":1,"showStatus":1,"sort":6,"icon":null,"productUnit":null,"productCount":0},{"catId":7,"name":"厨具","parentCid":0,"catLevel":1,"showStatus":1,"sort":7,"icon":null,"productUnit":null,"productCount":0},{"catId":8,"name":"个护化妆","parentCid":0,"catLevel":1,"showStatus":1,"sort":8,"icon":null,"productUnit":null,"productCount":0},{"catId":9,"name":"服饰内衣","parentCid":0,"catLevel":1,"showStatus":1,"sort":9,"icon":null,"productUnit":null,"productCount":0},{"catId":10,"name":"钟表","parentCid":0,"catLevel":1,"showStatus":0,"sort":0,"icon":null,"productUnit":null,"productCount":0},{"catId":11,"name":"鞋靴","parentCid":0,"catLevel":1,"showStatus":1,"sort":10,"icon":null,"productUnit":null,"productCount":0},{"catId":12,"name":"母婴","parentCid":0,"catLevel":1,"showStatus":1,"sort":11,"icon":null,"productUnit":null,"productCount":0},{"catId":13,"name":"礼品箱包","parentCid":0,"catLevel":1,"showStatus":1,"sort":12,"icon":null,"productUnit":null,"productCount":0},{"catId":14,"name":"食品饮料、保健食品","parentCid":0,"catLevel":1,"showStatus":1,"sort":13,"icon":null,"productUnit":null,"productCount":0},{"catId":15,"name":"珠宝","parentCid":0,"catLevel":1,"showStatus":1,"sort":14,"icon":null,"productUnit":null,"productCount":0},{"catId":16,"name":"汽车用品","parentCid":0,"catLevel":1,"showStatus":1,"sort":15,"icon":null,"productUnit":null,"productCount":0},{"catId":17,"name":"运动健康","parentCid":0,"catLevel":1,"showStatus":1,"sort":16,"icon":null,"productUnit":null,"productCount":0},{"catId":18,"name":"玩具乐器","parentCid":0,"catLevel":1,"showStatus":1,"sort":17,"icon":null,"productUnit":null,"productCount":0},{"catId":19,"name":"彩票、旅行、充值、票务","parentCid":0,"catLevel":1,"showStatus":1,"sort":18,"icon":null,"productUnit":null,"productCount":0},{"catId":20,"name":"生
