How to package spring boot multi-module projects?
I built a simple multi-module project:
Structure:
The outer pom.xml is as follows
<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.scum</groupId>
<artifactId>demo-package</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>demo-controller</module>
<module>demo-service</module>
</modules>
<build>
<plugins>
<plugin>
<!-- The plugin rewrites your manifest -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration><!-- 指定该Main Class为全局的唯一入口 -->
<mainClass>com.example.demo.DemoControllerApplication</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal><!--可以把依赖的包都打包到生成的Jar包中-->
</goals>
<!--可以生成不含依赖包的不可执行Jar包-->
<!-- configuration>
<classifier>exec</classifier>
</configuration> -->
</execution>
</executions>
</plugin>
</plugins></build>
</project>

Can run, packaged and reported that IndexService does not exist
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@SpringBootApplication
@Controller
public class DemoControllerApplication {
@Autowired
private IndexService indexService;
public static void main(String[] args) {
SpringApplication.run(DemoControllerApplication.class, args);
}
@RequestMapping(value = "")
@ResponseBody
public String index(){
return indexService.Index();
}
}
