springboot打war包时将外部配置文件打入到war包内

需求

客户适配信创改造，想把war包外的配置文件都放入到war内，方便迁移war和部署

使用maven-assembly-plugins插件

打包代码改造如下。在项目的pom.xml文件中加入maven-assembly-plugins插件如下所示

XML 复制代码

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>3.1.0</version>
    <executions>
        <execution>
            <id>private-bhbank</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
            <configuration>
                <descriptors>
                    <descriptor>src/main/resources/xxx.xml</descriptor>
                </descriptors>
                <finalName>api</finalName>
            </configuration>
        </execution>
    </executions>
</plugin>

然后在Resources目录下新建xxx.xml文件，内容如下所示

XML 复制代码

<assembly
        xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
    <id>private-bhbank</id>
    <includeBaseDirectory>false</includeBaseDirectory>
    <formats>
        <format>war</format>
    </formats>
    <fileSets>
        <!--将目录复制到指定位置-->
        <fileSet>
            <directory>target/classes/</directory>
            <outputDirectory>WEB-INF/classes</outputDirectory>
        </fileSet>
        <!--将单文件复制到指定位置-->
        <fileSet>
            <directory>config/</directory>
            <excludes>
                <exclude>application.properties</exclude>
            </excludes>
            <outputDirectory>WEB-INF/classes/config</outputDirectory>
        </fileSet>
        <!--将多文件复制到指定位置-->
        <fileSet>
            <directory>customerConfig/config-xxx</directory>
            <includes>
                <include>config.properties</include>
                <include>application.properties</include>
            </includes>
            <outputDirectory>WEB-INF/classes/config</outputDirectory>
        </fileSet>
        <fileSet>
            <directory>customerConfig/config-xxx</directory>
            <includes>
                <include>log4j2.xml</include>
            </includes>
            <outputDirectory>WEB-INF/classes</outputDirectory>
        </fileSet>
    </fileSets>
    <dependencySets>
        <dependencySet>
            <useProjectArtifact>false</useProjectArtifact>
            <outputDirectory>WEB-INF/lib</outputDirectory><!-- 将scope为runtime的依赖包打包到lib目录下。 -->
            <excludes>
                  <!--排除某些包-->
                <exclude>${包的groupId}:${包的artifactId}</exclude>
            </excludes>
        </dependencySet>
    </dependencySets>
</assembly>

按照上面改造后就可以在打包时将项目根目录的指定文件或目录复制到war包内的指定位置
