這是我pom.xml從 start.spring.io 生成的 M2 spring-boot 版本。這就是添加 maven spring 存儲庫的原因。但是找不到依賴項。 <?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>2.2.0.M2</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.example</groupId> <artifactId>auth-service</artifactId> <version>0.0.1-SNAPSHOT</version> <name>auth-service</name> <description>Authorization service</description> <properties> <java.version>11</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>com.okta.spring</groupId> <artifactId>okta-spring-boot-starter</artifactId> <version>1.1.0</version> </dependency> <dependency> <groupId>org.springframework.security.oauth</groupId> <artifactId>spring-security-oauth2</artifactId> <version>2.3.5.RELEASE</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>2.6.7</version> </dependency>

我從 start.spring.io 下載了一個類似的 spring 項目 - 2.2.0.M2，具有類似的依賴項。下面是我的 pom.xml 文件

<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.0.M2</version>

做了一個mvn clean compile，可以看到依賴項被下載到我的 .m2 文件夾并且構建成功。
下面是一個示例 Lombok 注釋
package com.example.demo;
import lombok.Value;
@Value
public class User {
String firstName;
String lastName;
}
以下是我的主要課程：
@SpringBootApplication
public class DemoApplication implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Override
public void run(String... args) {
User user = new User("Hello", "World");
System.out.println("First Name: " + user.getFirstName());
System.out.println("Last Name: " + user.getLastName());
System.out.println(user.toString());
}
}
下面是輸出：
2019-04-28 10:33:58.649 INFO 8732 --- [ main] com.example.demo.DemoApplication : No active profile set, falling back to default profiles: default
2019-04-28 10:34:01.069 INFO 8732 --- [ main] com.example.demo.DemoApplication : Started DemoApplication in 3.824 seconds (JVM running for 6.822)
First Name: Hello
Last Name: World
User(firstName=Hello, lastName=World)
Process finished with exit code
