Question

似乎spring boot会重新打包由maven包阶段生成的包，然后重新打包战争以使其可执行。

现在我想通过一个maven命令为不同的环境生成多个战争，我尝试使用maven-assembly-plugin：

1 unzip the war generated by `spring-boot-maven` plugin to a directory
2 Assembly with the files in the directory, and add some other filtered resources
3 create the war

查看此帖子：generate multiple artifacts in maven

虽然它有效但我有多次战争，但java -jar xx.war无法执行任何战争。这些类似乎已损坏。

所以我想知道是否有替代解决方案？

更新我的pom.xml：

            </includes>
        </fileSet>
    </fileSets>
</assembly>

更新

起初我得到了错误：

No main class detected

然后我为maven-assembly-plugin，

添加以下内容

<archive>
    <manifest>
        <mainClass>org.springframework.boot.loader.WarLauncher</mainClass>
    </manifest>
</archive>

之后我重新打包战争，当我跑步时出错：

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.ClassFormatError: Incompatible magic value 4022320623 in class file org/springframework/boot/loader/WarLauncher

当您重新打包war文件时，类文件已损坏。我怀疑是因为您正在过滤所有文件：

<fileSet>
    <directory>target/${project.build.finalName}-spring</directory>
    <outputDirectory>/</outputDirectory>
    <includes>
        <include>**/*</include>
    </includes>
    <filtered>true</filtered>
</fileSet>

您不想过滤二进制文件，因为它们可能恰好包含看起来像${}占位符的数据。您应该更新程序集以避免将过滤应用于类文件。最简单的方法是完全禁用过滤：

<fileSet>
    <directory>target/${project.build.finalName}-spring</directory>
    <outputDirectory>/</outputDirectory>
    <includes>
        <include>**/*</include>
    </includes>
    <filtered>false</filtered>
</fileSet>

如果需要过滤文本文件，则应使用两个fileSet。一个包含二进制文件并禁用过滤，一个包含文本文件并启用过滤。
