生成 EJB 客户端

通常，胖客户端应用程序只需要 EJB 项目的存根和实用程序类。EJB 插件能够生成 EJB JAR 供客户端使用。

要生成 ejb-client JAR，您需要在插件的配置中将generateClient设置为true ：

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-ejb-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
          <!-- this is false by default -->
          <generateClient>true</generateClient>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

客户包含和排除

ejb-client 归档的内容也可以使用包含和排除进行定制。

默认排除：

  • **/*Bean.class
  • **/*CMP.class
  • **/*Session.class
  • **/package.html

要对此进行自定义，请使用clientExcludes和clientIncludes元素：

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-ejb-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
          <clientIncludes>
             <!-- this will include all files and directories under com/foo/bar -->
             <clientInclude>com/foo/bar/**</clientInclude>
             <!-- this will include all files and directories under com/foo/acme -->
             <clientInclude>com/foo/acme/**</clientInclude>
             <!-- this will include all files under com/example -->
             <clientInclude>com/example/*</clientInclude>
          </clientIncludes>
          <clientExcludes>
             <!-- this will exclude all files under com/example -->
             <clientExclude>com/example/*</clientExclude>
             <!-- this will exclude all files and directories with the name
                  sparrow under com/jack -->
             <clientExclude>com/jack/**/sparrow</clientExclude>
          </clientExcludes>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>

注意：混合排除和包含时要小心，排除将比包含具有更高的优先级。
