如題：匯入一個新的spring boot專案作為spring cloud的一個子模組微服務，怎麼做
或者說每次匯入一個新的spring boot專案，IDEA不識別，啟動類無法啟動，怎麼解決
下面一起來走一遍這個流程：
1.將一個spring boot服務匯入spring cloud中作為一個子模組
如圖：這裡有一個現成的spring cloud微服務叢集，【如何建立一個spring cloud微服務：https://www.cnblogs.com/sxdcgaq8080/p/9035724.html】
然後
開啟本服務根目錄在資源管理器下：
可以看到根目錄下的現有的兩個ms 和parent的pom檔案
然後將想要加入的外部的一個spring boot專案貼上到此處【將tx-manager整個目錄拷貝過來】
如下：
修該名字為統一的ms名字
這個時候，再開啟idea ，看到
2.解決上面匯入但是沒有被識別的問題
所以先解決這個問題：
現將java目錄設定為tx-manager這個微服務的跟路徑
同理，設定resource目錄為根資源路徑
ok。現在就剩最後一個pom.xml檔案的轉變了
3.整理pom.xml檔案內容，建立和最外層parent的pom之間的父子依賴關係
先看一下最外層的parent的pom.xml完整的依賴：

再看一下現在的ms-member這個現成的子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>View Code
最後看一下現在的tx-manage的pom.xml依賴：
<?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.codingapi</groupId> <artifactId>tx-manager</artifactId> <version>4.2.0-SNAPSHOT</version> <packaging>jar</packaging> <name>tx-manager</name> <description>tx-manager</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <maven.compile.source>1.7</maven.compile.source> <maven.compile.target>1.7</maven.compile.target> <java.version>1.7</java.version> <guava.version>19.0</guava.version> <spring-cloud.version>Dalston.SR1</spring-cloud.version> <maven.deploy.skip>true</maven.deploy.skip> <maven.install.skip>true</maven.install.skip> </properties> <dependencies> <dependency> <groupId>com.github.1991wangliang</groupId> <artifactId>lorne_core</artifactId> <version>1.0.0</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>*</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>io.netty</groupId> <artifactId>netty-all</artifactId> <version>4.1.12.Final</version> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> <exclusions> <exclusion> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> </exclusion> </exclusions> </dependency> <!--<dependency>--> <!--<groupId>org.springframework.cloud</groupId>--> <!--<artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>--> <!--</dependency>--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-redis</artifactId> <version>1.3.8.RELEASE</version> </dependency> <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>${guava.version}</version> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.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>${maven-compiler-plugin.version}</version> <configuration> <source>${maven.compile.source}</source> <target>${maven.compile.target}</target> <encoding>${project.build.sourceEncoding}</encoding> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <version>2.8.2</version> <configuration> <skip>true</skip> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.6</version> <configuration> <archive> <manifest> <mainClass>com.codingapi.tm.TxManagerApplication</mainClass> <addClasspath>true</addClasspath> <classpathPrefix>lib/</classpathPrefix> </manifest> <manifestEntries> <Class-Path>./</Class-Path> </manifestEntries> </archive> <excludes> <exclude>config/**</exclude> </excludes> </configuration> </plugin> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <appendAssemblyId>false</appendAssemblyId> <descriptors> <descriptor>src/main/build/package.xml</descriptor> </descriptors> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>View Code
然後將tx-manager的pom按照member的更改：
<?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.codingapi</groupId> <artifactId>springcloud-ms-tx-manager</artifactId> <version>4.2.0-SNAPSHOT</version> <packaging>jar</packaging> <name>springcloud-ms-tx-manager</name> <description>tx-manager, LCN's distributed transaction coordinator</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> <dependencies> <dependency> <groupId>com.github.1991wangliang</groupId> <artifactId>lorne_core</artifactId> <version>1.0.0</version> <exclusions> <exclusion> <groupId>org.slf4j</groupId> <artifactId>*</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>io.netty</groupId> <artifactId>netty-all</artifactId> <version>4.1.12.Final</version> </dependency> </dependencies> </project>View Code
並且在parent的pom.xml檔案新增tx-manager子模組
最後匯入：點選import changes
最後可以看到 這個子模組的pom檔案終於被識別，並且父子依賴關係已經建立起來：
4.最後將tx-manager真正設立成子module
