为什么只有我的电脑看网站后台内容管理是乱码seo快排公司哪家好

maven

最主要的方式还是maven进行打包，也好进行配置项的管理
以下为pom文件（不要忘记修改部分参数）

pom.xml打包配置项（非完整版，仅含打包的内容< build>）

  <build><plugins><plugin><groupId>org.scala-tools</groupId><artifactId>maven-scala-plugin</artifactId><version>2.15.2</version><executions><execution><id>scala-compile-first</id><goals><goal>compile</goal></goals><configuration><includes><include>**/*.scala</include></includes></configuration></execution><execution><id>scala-test-compile</id><goals><goal>testCompile</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.0</version><configuration><source>8</source><target>8</target><encoding>UTF-8</encoding></configuration><executions><execution><phase>compile</phase><goals><goal>compile</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-shade-plugin</artifactId><executions><!-- Run shade goal on package phase --><execution><phase>package</phase><goals><goal>shade</goal></goals><configuration><filters><filter><!-- Do not copy the signatures in the META-INF folder.Otherwise, this might cause SecurityExceptions when using the JAR. --><artifact>*:*</artifact><excludes><exclude>META-INF/*.SF</exclude><exclude>META-INF/*.DSA</exclude><exclude>META-INF/*.RSA</exclude></excludes></filter></filters><transformers><transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"><mainClass>com.wunaiieq.SSJdbcRead</mainClass></transformer></transformers><createDependencyReducedPom>false</createDependencyReducedPom></configuration></execution></executions></plugin></plugins></build>

pom.xml完整示例（需要修改参数）

</project>

效果说明

打包后会弹出两个jar包
original-spark02-1.0-SNAPSHOT.jar：默认打包配置，不含其他依赖项
spark02-1.0-SNAPSHOT.jar：涵盖所有依赖文件（dependency）
