应用程序启动失败

说明：

试图调用一个不存在的方法。尝试从以下位置进行：

org.jclouds.json.internal.DeserializationConstructorAndReflectiveTypeAdapterFactory.<init>(DeserializationConstructorAndReflectiveTypeAdapterFactory.java:117)

以下方法不存在：

com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.<init>(Lcom/google/gson/internal/ConstructorConstructor;Lcom/google/gson/FieldNamingStrategy;Lcom/google/gson/internal/Excluder;)V

该方法的类 com.google.gson.internal.bind.ReflectiveTypeAdapterFactory 可从以下位置获得：

jar:file:/D:/JavaEE_development/JavaEEMvnRepository/.m2/repository/com/google/code/gson/gson/2.8.5/gson-2.8.5.jar!/com/google/gson/internal/bind/ReflectiveTypeAdapterFactory.class

它是从以下位置加载的：

file:/D:/JavaEE_development/JavaEEMvnRepository/.m2/repository/com/google/code/gson/gson/2.8.5/gson-2.8.5.jar

行动：

更正应用程序的类路径，使其包含一个兼容的 com.google.gson.internal.bind.ReflectiveTypeAdapterFactory 版本

进程以退出代码 1 结束

【问题讨论】：

    标签： maven spring-boot gson jclouds


    【解决方案1】：

    对于那些使用 jCloud 遇到同样问题的人，问题是当您使用 Gson 或 guava 或包含在 jcloud 依赖项中的任何库时，您可以使用特定版本但 jcloud 使用另一个版本的您在类路径中使用的相同库可能会由于 classpath 上的重复类而导致类加载冲突。 在我的情况下，冲突是由于使用 google-Gson 和 google-guava

    我的代码中的库是一个新版本，它也带有 jcloud 作为旧版本。解决方案是创建一个 jcloud 库的着色 jar 文件，在其中着色您在 classPath 中使用的所有重复库 我通过创建一个包含以下 pom 的 maven 项目来做到这一点：

    <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>jcloud.eagleboard</groupId>
  <artifactId>jcloud-shaded</artifactId>
  <version>1.0-SNAPSHOT</version>

  <properties>
    <jclouds.version>2.1.2</jclouds.version>
  </properties>
  <dependencies>
    <dependency>
      <groupId>org.apache.jclouds</groupId>
      <artifactId>jclouds-core</artifactId>
      <version>${jclouds.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.jclouds</groupId>
      <artifactId>jclouds-blobstore</artifactId>
      <version>${jclouds.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.jclouds.api</groupId>
      <artifactId>filesystem</artifactId>
      <version>${jclouds.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.jclouds.provider</groupId>
      <artifactId>aws-s3</artifactId>
      <version>${jclouds.version}</version>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4.3</version>
        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <relocations>
                <relocation>
                  <pattern>com.google</pattern>
                  <shadedPattern>com.shaded</shadedPattern>
                </relocation>
              </relocations>
              <transformers>
                <transformer
                  implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

    然后我在终端使用如下命令打包：

    mvn package

    然后在目标目录中创建一个名为jcloud-shaded-1.0-SNAPSHOT 的文件，名称取决于您构建阴影 pom 文件的方式。 将该文件复制到项目的主目录中，例如在名为 local-maven-repo 的目录中。

    然后创建本地存储库并向您的项目添加对生成的 jar 文件和您在其中使用 jar 文件创建的存储库的依赖项

    mvn install:install-file -Dfile=./local-maven-repo/jcloud-shaded-1.0-SNAPSHOT.jar -DgroupId=jcloud.eagleboard -DartifactId=jcloud-shaded -Dversion=1.0-SNAPSHOT -Dpackaging=jar

    在我的项目 pom 文件中包含了对本地阴影 jar 的依赖：

    <repositories>
    <repository>
      <id>local-maven-repo</id>
      <url>file://${project.basedir}/local-maven-repo</url>
    </repository>
</repositories>

    ... ...

    <dependency>
      <groupId>jcloud.eagleboard</groupId>
      <artifactId>jcloud-shaded</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>

    【讨论】：

      【解决方案2】：

      尝试升级到 jclouds 2.2.0-SNAPSHOT。这包括对JCLOUDS-1166 和JCLOUDS-1500 的修复，这可能会修复您的症状。

      【讨论】：

      • 无法升级到 jcloud 2.2.0-SNAPSHOT，就像在 maven 上找不到一样，或者如果我弄错了，请您澄清一下。
      • 访问jclouds.apache.org/start/install，选择“Maven”，然后查看“每日构建”部分。
      • 我升级了它，但仍然出现同样的错误
