如题：导入一个新的spring boot项目作为spring cloud的一个子模块微服务，怎么做

或者说每次导入一个新的spring boot项目，IDEA不识别，启动类无法启动，怎么解决

下面分别展示 [tx-manager只是作为例子进行操作，你可以把这个服务名字想象成例如springcloud-ms-xxx等等都可以]

一.只需要将一个spring boot服务识别为子模块，不会建立真正的父子依赖关系

将tx-Manager修改为本微服务组可以识别的子模块module

成功识别为子module

二.需要建立真正父子依赖关系的 子模块识别

下面一起来走一遍这个流程：

1.将一个spring boot服务导入spring cloud中作为一个子模块

如图：这里有一个现成的spring cloud微服务集群，【 如何创建一个spring cloud微服务：https://www.cnblogs.com/sxdcgaq8080/p/9035724.html 】

打开本服务根目录在资源管理器下：

可以看到根目录下的现有的两个ms 和parent的pom文件

然后将想要加入的外部的一个spring boot项目粘贴到此处【将tx-manager整个目录拷贝过来】

修该名字为统一的ms名字

这个时候，再打开idea ，看到

2.解决上面导入但是没有被识别的问题

所以先解决这个问题：

现将java目录设置为tx-manager这个微服务的跟路径

同理，设置resource目录为根资源路径

ok。现在就剩最后一个pom.xml文件的转变了

3.整理pom.xml文件内容，建立和最外层parent的pom之间的父子依赖关系

先看一下最外层的parent的pom.xml完整的依赖： 

<?xml version="1.0" encoding="UTF-8"?>

    <artifactId>springcloud</artifactId>

    注意 最后打包 最外层的pom 需要更改为 pom而不是jar
