篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spring cloud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 每次导入一个新的spring boot项目,IDEA不识别子module(代相关的知识,希望对你有一定的参考价值。
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
导入更新
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】
然后
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】
如下:
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:

再看一下现在的ms-member这个现成的子module的pom.xml
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.swapping</groupId> <artifactId>springcloud-ms-member</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>springcloud-ms-member</name> <description>ms-member is consumer ,transfer ms-order and ms-integral</description> <parent> <groupId>com.swapping</groupId> <artifactId>springcloud</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> </project>
最后看一下现在的tx-manage的pom.xml依赖:
