如何使用Ant(或Maven)动态创建jaxb.in​​dex文件

Question

这更多的是知识共享而不是提问.认为这个小Ant片段可能对某人有用.

<target name="create-jaxb-index" depends="compile">
    <!-- Create a suitable jaxb.index file on the fly to remove the need for an ObjectFactory
         jaxb.index is a simple list of the domain objects without package or extension, e.g.
         org.example.Domain.java -> Domain
    -->
    <fileset id="domain-sources" dir="${src}">
      <include name="org/example/*.java"/>
    </fileset>
    <pathconvert property="domain-list" refid="domain-sources" pathsep="${line.separator}">
      <chainedmapper>
        <flattenmapper/>
        <globmapper from="*.java" to="*" casesensitive="false"/>
      </chainedmapper>
    </pathconvert>
    <echo file="${target}/classes/org/example/jaxb.index" message="${domain-list}"/>
  </target>

好的,好的,所以它不会全部存储并存储所有的包名称,以便它可以重建适当的文件结构,但它足以让你开始.

希望能帮助到你.

此外,您可以将这个小片段(少于目标元素)插入到Maven构建中,如下所示:

  <plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.3</version>
    <executions>
      <execution>
        <phase>compile</phase>
        <configuration>
          <tasks>
              <!-- Create a suitable jaxb.index file on the fly to remove the need for an ObjectFactory
                   jaxb.index is a simple list of the domain objects without package or extension, e.g.
                   org.example.Domain.java -> Domain
              -->
              <fileset id="domain-sources" dir="${build.sourceDirectory}">
                <include name="org/example/domain/*.java"/>
              </fileset>
              <pathconvert property="domain-list" refid="domain-sources" pathsep="${line.separator}">
                <chainedmapper>
                  <flattenmapper/>
                  <globmapper from="*.java" to="*" casesensitive="false"/>
                </chainedmapper>
              </pathconvert>
              <echo file="${build.outputDirectory}/org/example/domain/jaxb.index" message="${domain-list}"/>
          </tasks>
        </configuration>
        <goals>
          <goal>run</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

您还可以使用JAXB2 Basics中的JAXBIndex 插件。
