Question

我使用maven创建了一个java项目，并构建了一个可执行的jar文件。在我的班上，我定义了以下内容。

Public class Main{
      public static void main(String[] args) {

         System.setProperty("javax.net.ssl.trustStore", keypath);
         System.setProperty("javax.net.ssl.trustStorePassword", pwd);
             ....
       //do a https request

      } 
}

当我使用jar -java xx.jar运行可执行jar时，我收到以下错误

 java.net.SocketException: java.security.NoSuchAlgorithmException: Error constructing implementation (algorithm: Default, provider: SunJSSE, class: com.sun.net.ssl.internal.ssl.DefaultSSLContextImpl)

我使用maven-dependency-plugin导入了项目所需的所有其他库。我是否还必须导入jdk库。如果是这样的话。有没有不同的方法

谢谢

密钥库采用.jks格式。

Answer 1

我找到了问题的解决方案。当我检查输出包中的.jks文件（在maven构建之后）和原始.jks文件的大小时，存在大小差异。在没有过滤的想法的情况下，我在maven-resource-plugin中应用了过滤。取下后，罐子工作了。

      <plugin>
            <artifactId>maven-resources-plugin</artifactId>
            <version>2.6</version>
            <executions>
                <execution>
                    <id>copy-resources</id>
                    <phase>validate</phase>
                    <goals>
                        <goal>copy-resources</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/resources/</outputDirectory>
                        <resources>
                            <resource>
                                <directory>src/main/resources</directory>
                                <!--<filtering>true</filtering>-->
                            </resource>
                        </resources>
                    </configuration>
                </execution>
