4.2. MicroProfile 配置开发

流程

1. 设置 Maven 项目。

   $ mvn archetype:generate \
       -DgroupId=com.example \
       -DartifactId=microprofile-config \
       -DinteractiveMode=false \
       -DarchetypeGroupId=org.apache.maven.archetypes \
       -DarchetypeArtifactId=maven-archetype-webapp
   cd microprofile-config

   Copy to Clipboard Toggle word wrap

   这将为项目和 pom.xml 配置文件创建目录结构。

2. 要让 POM 文件自动管理 jboss-eap-xp-microprofile BOM 中的 MicroProfile Config 构件和 MicroProfile REST 客户端构件的版本，请将 BOM 导入到项目 POM 文件的 <dependencyManagement> 部分中。

   <dependencyManagement>
     <dependencies>
       <!-- importing the microprofile BOM adds MicroProfile specs -->
       <dependency>
           <groupId>org.jboss.bom</groupId>
           <artifactId>jboss-eap-xp-microprofile</artifactId>
           <version>3.0.0.GA</version>
           <type>pom</type>
           <scope>import</scope>
       </dependency>
     </dependencies>
   </dependencyManagement>

3. 将 MicroProfile Config 构件和 MicroProfile REST 客户端构件和其他依赖项（由 BOM 管理）添加到 POM 文件的 <dependency> 部分。以下示例演示了将 MicroProfile Config 和 MicroProfile REST 客户端依赖项添加到该文件中：

   <!-- Add the MicroProfile REST Client API. Set provided for the <scope> tag, as the API is included in the server. -->
   <dependency>
     <groupId>org.eclipse.microprofile.rest.client</groupId>
     <artifactId>microprofile-rest-client-api</artifactId>
     <scope>provided</scope>
   </dependency>
   <!-- Add the MicroProfile Config API. Set provided for the <scope> tag, as the API is included in the server. -->
   <dependency>
     <groupId>org.eclipse.microprofile.config</groupId>
     <artifactId>microprofile-config-api</artifactId>
     <scope>provided</scope>
   </dependency>
   <!-- Add the {JAX-RS} API. Set provided for the <scope> tag, as the API is included in the server. -->
   <dependency>
     <groupId>org.jboss.spec.javax.ws.rs</groupId>
     <artifactId>jboss-jaxrs-api_2.1_spec</artifactId>
     <scope>provided</scope>
   </dependency>
   <!-- Add the CDI API. Set provided for the <scope> tag, as the API is included in the server. -->
   <dependency>
     <groupId>jakarta.enterprise</groupId>
     <artifactId>jakarta.enterprise.cdi-api</artifactId>
     <scope>provided</scope>
   </dependency>
