1.parent基于自己项目而非spring-boot-starter-parent

　　目前解决方案

　　　　（1）所有的springboot依赖显示写出版本号

　　　　（2）plugin显示写出执行目标repackage

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>2.0.1.RELEASE</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <version>2.0.1.RELEASE</version>
            <scope>test</scope>
        </dependency>

        <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>2.0.1.RELEASE</version>
                <configuration>
                    <classifier>exec</classifier>
                   <executable>true</executable>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
                    

note: <classifier>exec</classifier>该标签作用是如果有其他项目依赖该项目时，会打成两个jar，一个是xxx.jar（别的项目依赖用)另一个是xxx-exec.jar（部署执行用)

2.idea run没问题，打成jar包执行报资源文件找不到

　　目前解决方案是拷贝一份资源文件到classes目录下即可

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

                    </execution>
                </executions>
            </plugin>

 如果idea run也报资源文件找不到

　　（1）检查该文件是否存在resources文件夹内

       （2）检查resources文件夹是否为Resources Root 。否则右键Mark Directory As --> Resources Root 即可
