我以這種方式在spring boot應用程序中有一個通用的jar文件，package com.acc.api;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationContext;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;@SpringBootApplication@ComponentScan(basePackages = {"com.acc.api","service"})public class ApicoreApplication {    public static void main(String[] args) {        ApplicationContext applicationContext = SpringApplication.run(ApicoreApplication.class, args);        for (String name: applicationContext.getBeanDefinitionNames()) {            System.out.println(name);        }    }}其中的組件是，package com.acc.api.core.utils;import java.util.Map;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;@Componentpublic class AccUtil {    @Autowired    private WebServiceEngine engine;}其中 WebServiceEngine 是我調用的第三方 api。我的 pom 條目是這樣的，<?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>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>2.1.2.RELEASE</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <groupId>com.acc.api</groupId>    <artifactId>apicore</artifactId>    <version>0.0.1</version>    <name>apicore</name>    <description>apicore</description>    <properties>        <java.version>1.8</java.version>    </properties>直到這很好，項目正在編譯，jar 正在目標文件夾中創建。
