本来想着等待javamis低代码开发平台完全研发完成后，再按照功能模块的方式一一将功能点详细写出来，但随着javamis平台越研发越大，就会导致前面研发功能模块过程的知识点遗漏记下来，经过仔细思考后，决定还是先不要那么完美，在开发过程遇到哪些功能点就记录哪些，以免知识点再次遗漏，待整个javamis平台研发完，再整理博客的顺序 - 便于小伙伴们的参考，同时，请小伙伴们届时留意我的动态发布内容，欢迎加入QQ技术交流群：327773608 |
这是因为，服务监控模块可以实现实时动态的展示出java 虚拟机(jvm)的动态情况，帮助管理人员对服务器的软件、硬件的维护....，平台采用OSHI免费的跨平台服务器检测来实现。
javamis-parent父工程下，pom.xml文件添加以下依赖
1 <properties> 2 <oshi.version>6.4.5</oshi.version> 3 <jna.version>5.13.0</jna.version> 4 </properties>
1 <dependencyManagement> 2 <dependencies> 3 <!-- 监控服务-获取系统信息 --> 4 <dependency> 5 <groupId>com.github.oshi</groupId> 6 <artifactId>oshi-core</artifactId> 7 <version>${oshi.version}</version> 8 </dependency> 9 <dependency> 10 <groupId>net.java.dev.jna</groupId> 11 <artifactId>jna</artifactId> 12 <version>${jna.version}</version> 13 </dependency> 14 <dependency> 15 <groupId>net.java.dev.jna</groupId> 16 <artifactId>jna-platform</artifactId> 17 <version>${jna.version}</version> 18 </dependency> 19 </dependencies> 20 </dependencyManagement>
javamis-core 子核心工程下，pom.xml文件引用父工程的依赖
1 <dependencies> 2 <!-- 监控服务-获取系统信息 --> 3 <dependency> 4 <groupId>com.github.oshi</groupId> 5 <artifactId>oshi-core</artifactId> 6 </dependency> 7 <dependency> 8 <groupId>net.java.dev.jna</groupId> 9 <artifactId>jna</artifactId> 10 </dependency> 11 <dependency> 12 <groupId>net.java.dev.jna</groupId> 13 <artifactId>jna-platform</artifactId> 14 </dependency> 15 </dependencies>
注1：以上引入oshi和jna包时，请注意：需要先在父工程javamis-parent下引入， 然后再子工程javamis-core下引入使用！
注2： 如果报：“ java.lang.NoClassDefFoundError: com/sun/jna/platform/win32/VersionHelpers”，请检查是否引用了jna和jna-platform！！！
注3：请检查您是否使用了最新版本，这果我使用的版本为：oshi最新版本：6.46；jna和jna-platform最新版本：5.13.0；
