用idea打包

idea的pom.xml

红色字体为打包必须依赖的：

注：如果是使用普通的maven编译器，（就不会要求指定mainClass类）那build标签应该这样写：

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>${project.build.sourceEncoding}</encoding>
                </configuration>
            </plugin>
        </plugins>
    </build>

如果是该包上传到自己的私服那么需要在pom.xml文件中加入:

<distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://xxxx:10890/nexus/content/repositories/releases/</url>
        </repository>
    </distributionManagement>

接下来，在idea里打包，如果是maven父子模块项目，那么在打包时为了防止子模块之间的依赖关系，需要打包父模块的pom.xml文件，具体方式见下图：ciems-service-operation-management就是父模块

生成的jar包在启动的时候，执行java -jar 命令时，有点时候会因为utf-8编码问题报错，所以为了解决报错，需要执行:

 java -Dfile.encoding=utf-8 -jar springboot服务
