活用maven使web.xml可以用maven变量

活用maven使web.xml可以用maven变量

废话不多说，直接上代码

    <build>

        <finalName>${finalWarName}</finalName>

        <defaultGoal>compile</defaultGoal>

        <resources>

          <resource>

            <directory>src/main/resources</directory>

            <filtering>true</filtering>

          </resource>

          <resource>

            <directory>src/main/webapp</directory>

            <filtering>true</filtering>

            <includes>

                <include>WEB-INF/web.xml</include>

            </includes>

            <targetPath>${project.build.directory}/${project.build.finalName}</targetPath>

          </resource>

         </resources>

    <plugins>

        <plugin>

            <groupId>org.apache.maven.plugins</groupId>

            <artifactId>maven-war-plugin</artifactId>

            <version>2.4</version>

            <configuration>

            <!-- http://maven.apache.org/plugins/maven-war-plugin/ -->

            <webXml>src/main/webapp/WEB-INF/web.xml</webXml>

            <outputDirectory>${war.outpath}</outputDirectory>

            </configuration>

        </plugin>

     </plugins>

      </build>

重点是在resource中包含了web.xml并将其输出至默认目录，并在war插件中指明webXml属性，此二者缺一不可

效果：

打包前：

  <context-param>

       <param-name>spring.profiles.default</param-name>

       <param-value>${datasource.type}</param-value>

  </context-param>

打包后：

  <context-param>

       <param-name>spring.profiles.default</param-name>

       <param-value>JDBC</param-value>

  </context-param>
