spring-boot-configuration-processor不在maven子模块项目上工作

Question

我有一个maven多模块项目，有一个父模块和三个子模块。应用程序使用spring Boot。在其中一个子模块中，我有SpringBootApplication：

@SpringBootApplication
@EnableConfigurationProperties({AppProperties.class})
public class MainSpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(MainSpringBootApplication.class, args);
    }
}

@Data
@ConfigurationProperties(prefix = "asdf")
public class AppProperties {
...
}

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-configuration-processor</artifactId>
  <optional>true</optional>
</dependency>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.3.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

你有什么提示吗？

Answer 1

我明确地添加了：

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.0</version>
    <configuration>
      <annotationProcessorPaths>
        <annotationProcessorPath>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-configuration-processor</artifactId>
          <version>2.1.5.RELEASE</version>
        </annotationProcessorPath>
      </annotationProcessorPaths>
    </configuration>
  </plugin>

到包含@configurationproperties注释类的子模块pom的plugins部分。现在生成target/classes/meta-inf/spring-configuration-metadata.json。
