IDEA 上运行是ok的，打jar包部署到服务器或者本机，就报错，应用的tibco jar包貌似没
打包进来，百度各种方式都试了。
可留联系方式，解决了发红包。
启动 代码
@SpringBootApplication
@ServletComponentScan(basePackages = "com.fdcweb.filter")
@EnableAutoConfiguration
@EnableScheduling
@EnableAsync
public class FdcwebApplication {
public static void main(String[] args) {
SpringApplication.run(FdcwebApplication.class, args);
String service = "1200";
String network = ";225.19.19.12";
String daemon = "7500";
String subject = "cm.test";
RvlistenerDemo rl = new RvlistenerDemo(service, network, daemon, subject);
}
}

pom.xml的打jar包换成这种：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.2.0</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>codes.showme.mavenrepocrawler.Crawler</mainClass> <!-- 此处为主入口-->
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<!--<configuration>-->
<!--<outputDirectory>${project.build.directory}/lib-->
<!--</outputDirectory>-->
<!--</configuration>-->
</execution>
</executions>
</plugin>
然后Teminal 输入mvn clean install
然后会在targer目录生成一个dependency的目录。在里面查看所有依赖的jar到底有否打进去
前几天也碰到了依赖打不进去的问题。这样能快速排查出来

<goals>
<goal>copy-dependencies</goal>
</goals>
这个 地方 爆红
没有打进来
@nieaitan520: 爆红那个不影响。你tibco这个包怎么引入的。maven坐标还是外部依赖
@Ctrl`: 打包成功了，分享下方法，留下电话，给你充点话费，幸苦大哥了。
<dependency>
<groupId>com.tibco</groupId>
<artifactId>tibrvj</artifactId>
<version>1.0.0</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/tibrvj.jar</systemPath>
</dependency>
引入外部依赖的包，指定路径
打包的时候
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
<configuration>
<includeSystemScope>true</includeSystemScope> <!-- 打包 将外部jar，打包进项目中 -->
</configuration>
</plugin>
昨天打包不成功是看到网上说<artifactId>tibrvj</artifactId> 这个地方随便写，我就写了<artifactId>com.tibrvj</artifactId>，结果是指定的文件夹，今天我看了写log，找到原因了，谢谢大哥，大哥辛苦了
@nieaitan520: 。没事的 解决了就好，话费就免了。正常结下贴就行 -

tibco jar 是引了多个版本的吗
