Question

我正在尝试使用springboot java框架编译集成服务器。我正在使用Maven编译一个jar文件，但是我一直在遇到Maven将jar存储在存储库中的问题。

我正在使用的Jar是sapjco3.jar，它会在运行时崩溃（不是包）因为它的名字是sapjco3.jar。因为Maven repo命名约定是：

/%groupId%/%artifactId%/%version%/%artifactId%-%version%.jar

该库最终被称为sapjco3-3.0.jar。

有没有办法在不使用存储库的情况下将sapjco3.jar弹出到我的应用程序中（我无法将其添加到java.library.path或通过编辑〜/ .m2中的条目和xml目录）。否则，有没有办法在插入后重命名它？

顺便说一句，我的平台是ubuntu 14.04 LTS。

我的POM文件（缺少xml标头，因为StackOverflow没有正确解析它）：

崩溃：

Factory method 'createSapConnection' threw exception; nested exception is java.lang.ExceptionInInitializerError: JCo initialization failed with java.lang.ExceptionInInitializerError: Illegal JCo archive "sapjco3-3.0.jar". It is not allowed to rename or repackage the original archive "sapjco3.jar".

我用自定义布局解决了这个问题

import org.springframework.boot.loader.tools.Layouts.Jar;

public class ResistantToSapjco3JarLayout extends Jar implements CustomLoaderLayout {

  @Override
  public void writeLoadedClasses(LoaderClassesWriter writer) throws IOException {

    // do Spring Boot defaults
    writer.writeLoaderClasses();

    URL jcoClassUrl = getClass().getClassLoader().getResource("com/sap/conn/jco/JCo.class");
    if (jcoClassUrl == null) {
        throw new IllegalStateException("No sapjco3 JAR on plugin classpath. "
                + "Make sure sapjco3 is added to spring-boot-maven-plugin dependency section");
    }
    if (!jcoClassUrl.toString().startsWith("jar:file")) {
        throw new IllegalStateException("sapjco3 is not JAR");
    }
    JarURLConnection jarUrlConnection = (JarURLConnection) jcoClassUrl.openConnection();
    JarFile sapjco3Jar = jarUrlConnection.getJarFile();

    JarWriter jarWriter = (JarWriter) writer;
    jarWriter.writeNestedLibrary("BOOT-INF/lib/",
      new Library("sapjco3.jar", new File(sapjco3Jar.getName()), LibraryScope.COMPILE, false));

  }

}

的pom.xml

<plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
      <layoutFactory implementation="com.company.ResistantToSapjco3JarLayoutFactory" />
      <excludeArtifactIds>sapjco3</excludeArtifactIds>
    </configuration>
    <dependencies>
        <dependency>

            <artifactId>resistant-to-sapjco3</artifactId>

        </dependency>
        <dependency>
            <groupId>sapjco3</groupId>
            <artifactId>sapjco3</artifactId>
            <version>3.0.13</version>
        </dependency>
    </dependencies>
</plugin>

ResistantToSapjco3JarLayoutFactory

public class ResistantToSapjco3JarLayoutFactory implements LayoutFactory {

  @Override
  public Layout getLayout(File source) {
        return new ResistantToSapjco3JarLayout();
  }
}

Answer 2

我使用了Maven的shade插件解决了这个问题。具有提供范围的sapjco3的maven依赖项：

<dependency>
  <groupId>com.sap.conn.jco</groupId>
  <artifactId>sapjco3</artifactId>
  <version>${sapjco3.version}</version>
  <scope>provided</scope>
</dependency>

然后通过在着色时复制库并在spring maven插件添加其版本时排除该库来完成工作，以便我们拥有原始库：

<finalName>price</finalName>

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