[若依]微服务springcloud版新建增添加一个业务子模块微服务
若依框架是一个比较出名的后台管理系统，有多个不同版本。本文介绍微服务版本如何新增一个微服务模块，类似System模块，对外提供服务。
阅读使用本文的前提是已经成功搭建起来了ruoyi的springcloud版本的环境。
### 新建模块
在modules模块下新建module
!(data/attachment/forum/202207/07/122333ww5188p77p78peuw.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
根据实际需要填写即可
!(data/attachment/forum/202207/07/122354en87eu82wtb0ojch.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
创建完成之后，删除无用的内容，比如resource下的template，按需删除即可
### 设置pom
直接复制ruoyi-modules-system的系统模块的pom.xml，然后对其内容进行修改，仅仅需要修改两个点，一个是artifactId一个是description

### 设置resource内容
复制ruoyi-system的resources文件夹下的banner.txt,bootstrap.yml,logback.xml文件到ruoyi-xxx模块(刚才新建的模块)
#### 修改banner
banner动画，自行设置即可，有很多生成网站
#### 修改bootstrap.yml
端口号修改为你需要的，比如9205
修改应用名称，如ruoyi-xxx
```
# Tomcat
server:
port: 9205
# Spring
spring:
application:
# 应用名称
name: ruoyi-xxx
```
#### 修改logback.xml中日志存放路径
```
<!-- 日志存放路径 -->
<property name="log.path" value="logs/ruoyi-xxx" />
```
### 配置nacos
#### 创建配置
登录nacos，根据system配置文件，克隆一个
!(data/attachment/forum/202207/07/123326tnyk3kyvp399nazp.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
注意dataID为 ruoyi-xxx-dev dev是环境
!(data/attachment/forum/202207/07/123500m68myz6s5s5l4s88.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")
修改mybatis部分配置
```
mybatis:
# 搜索指定包别名
typeAliasesPackage: com.ruoyi.xxx
# 配置mapper的扫描，找到所有的mapper.xml映射文件
mapperLocations: classpath:mapper/**/*.xml
```
#### 配置网关
修改ruoyi-gateway-dev.yml网管的配置文件，仿照上面system的配置复制出来一份，并修改为新模块所对应的。
```
# xxx模块
- id: ruoyi-xxx
uri: lb://ruoyi-xxx
predicates:
- Path=/xxx/**
filters:
- StripPrefix=1
```
#### 配置sentinel
修改配置文件 sentinel-ruoyi-gateway
```
{
"resource": "ruoyi-xxx",
"count": 1000,
"grade": 1,
"limitApp": "default",
"strategy": 0,
"controlBehavior": 0
},
```
### 调整启动类
参照RuoYiSystemApplication，具体地说就是直接复制几个注解即可，参考代码如下
```java
@EnableCustomConfig
@EnableCustomSwagger2
@EnableRyFeignClients
@SpringBootApplication
public class RuoYiSystemApplication
{
public static void main(String[] args)
{
SpringApplication.run(RuoYiSystemApplication.class, args);
System.out.println("(♥◠‿◠)ﾉﾞ系统模块启动成功 ლ(´ڡ`ლ)ﾞ\n" +
" .-------. ____ __ \n" +
" |_ _ \\ \\ \\ // \n" +
" | ( ' )| \\_. /' \n" +
" |(_ o _) / _( )_ .' \n" +
" | (_,_).' _____(_ o _)' \n" +
" ||\\ \\||| |(_,_)' \n" +
" || \\ `' /| `-'/ \n" +
" ||\\ /\\ / \n" +
" ''-' `'-' `-..-' ");
}
}
```
### 配置完成，启动
```
Spring Boot Version: 2.6.7
Spring Application Name: ruoyi-xxx
