SpringBoot：マルチモジュールプロジェクトを実行中

Question

私は基本的なSpringBootアプリケーションを持っています。 Spring Initializer、組み込みTomcat、Thymeleafテンプレートエンジン、およびパッケージを実行可能なJARファイルとして使用しています。 は、Spring Bootを使用したマルチモジュールプロジェクトです。プロジェクトには3つのモジュールがあります。ここで ここでは、親モジュールのpom.xml

私が使用してすべてのモジュールを生成し、親のルートから：

mvn clean package 

しかし、問題はtdk-web-0.0.2-SNAPSHOT.jarがtdk-core-0.0.2-SNAPSHOT.jarが含まれていませんし、それはここではMavenの結果、起動

に失敗したということです。

は、これは私が得たエラーです：

*************************** 
APPLICATION FAILED TO START 
*************************** 

Description: 

Field emailService in com.tdkcloud.web.controllers.AppErrorController required a bean of type 'com.tdkcloud.backend.service.EmailService' that could not be found. 


Action: 

Consider defining a bean of type 'com.tdkcloud.backend.service.EmailService' in your configuration. 

私は瓶を解凍し、コアモジュールのクラスはありません

モジュールウェブに提案コードを追加：

<plugin> 
        <artifactId>maven-dependency-plugin</artifactId> 
        <executions> 
         <execution> 
          <phase>install</phase> 
          <goals> 
           <goal>copy-dependencies</goal> 
          </goals> 
          <configuration> 
           <outputDirectory>${project.build.directory}/lib</outputDirectory> 
          </configuration> 
         </execution> 
        </executions> 
       </plugin> 

は、私は次のエラーがあります： Error resolving template "/tdk/login/login", template might not exist or might not be accessible by any of the configured Template Reso

をしかしテンプレートがあります：あなたは、コアモジュールでversion欠けている

Answer 1

最近私は、プロジェクト構造/レイアウトの1つをmavenマルチモジュールプロジェクトとして実装しようとしました。

私はスプリングガイドリンク以下に続く

が、これはエラーの説明によると、あなたと他の人 Official Spring multi module project link

Answer 2

。以下のコアモジュールを追加してください。

<version>0.0.2-SNAPSHOT</version> 

となります。

<groupId>com.tdkcloud.core</groupId> 
<artifactId>tdk-core</artifactId> 
<packaging>jar</packaging> 
<version>0.0.2-SNAPSHOT</version> 

Answer 3

これを追加してください。

 <plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId> 
      <executions> 
       <execution> 
        <goals> 
         <goal>repackage</goal> 
        </goals> 
        <configuration> 
         <classifier>exec</classifier> 
        </configuration> 
       </execution> 
      </executions> 
     </plugin> 

Repackages existing JAR and WAR archives so that they can be executed from the command line using java -jar. With layout=NONE can also be used simply to package a JAR with nested dependencies (and no main class, so not executable).

Answer 4

から私は以前、同じ問題に直面していました。私はあなたが爆発した形で瓶を運んでいないと推測しています。このプラグインを使用すると、バンドル内のjarファイルをプルして.original jarファイルを実行する必要があります。

これは、jar内でpomに定義したすべての依存関係をバンドルします。お役に立てれば。

Answer 5

  <plugin> 
       <groupId>org.springframework.boot</groupId> 
       <artifactId>spring-boot-maven-plugin</artifactId> 
       <configuration> 
        <executable>true</executable> 
       </configuration> 
       <executions> 
        <execution> 
         <goals> 
          <goal>repackage</goal> 
         </goals> 
        </execution> 
       </executions> 
      </plugin> 

実行可能なJarを作成するためにこれを提案します。

Answer 6

あなたの@ComponentScan注釈がないか、間違っていると思います。 （例：@ComponentScan（{"com.tdkcloud。。。ウェブ "}））com.tdkcloud.backendパッケージでサービスを見つけることができませんそれとも@Service注釈があなたのEmailServiceから欠落している

だから、これを解決するために、あなたのコードは、このような何かを見てする必要があります：

App.java（又はWebconfig.java）

@Configuration 
@EnableWebMvc 
@ComponentScan({"com.tdkcloud"}) 
@SpringBootApplication 
public class App { 
    ... 
} 

EmailService.java

public interface EmailService { 
    ... 
} 

EmailServiceImpl.java

@Service 
public class EmailServiceImpl { 
    ... 
}
