Working with different DBMS for programmers in their daily work represents a significant challenge in terms of choosing the appropriate way of connecting to the DBMS for the appropriate needs, given that a significant number of factors can influence the same. Although experience is usually one of the important elements that has influence on the selection of the appropriate way to connect to a DBMS, the choice can still vary from system to system and from situation to situation. For this reason, it is necessary to conduct appropriate analysis and research in accordance with various factors that can be an indicator of whether a connection with a DBMS is good or bad. In this research, an analysis was performed between the two leading methods of interaction between java spring Boot applications and PostgreSQL databases, namely spring JDBC and spring Hibernate. The results of the analysis indicate that there are certain differences in the speed of query execution in certain situations, which java programmers should pay special attention to when choosing one of the two mentioned technologies to achieve more complex functionalities.

Location decision of low-altitude service station for transfer flight based on modified immune algorithm

The location of Low-Altitude Flight Service Station (LAFSS) is a comprehensive decision work, and it is also a multi-objective optimization problem (MOOP) with constraints. As a swarm intelligence search algorithm for solving constrained MOOP, the Immune Algorithm (IA) retains the excellent characteristics of genetic algorithm. Using some characteristic information or knowledge of the problem selectively and purposefully, the degradation phenomenon in the optimization process can be suppressed and the global optimum can be achieved. However, due to the large range involved in the low-altitude transition flight, the geographical characteristics, economic level and service requirements among the candidate stations in the corridor are quite different, and the operational safety and service efficiency are interrelated and conflict with each other. And all objectives cannot be optimal. Therefore, this article proposes a Modified Immune Algorithm (MIA) with two-layer response to solve the constrained multi-objective location mathematical model of LAFSS. The first layer uses the demand track as the cell membrane positioning pattern recognition service response distance to trigger the innate immunity to achieve the basic requirements of security service coverage. In the second layer, the expansion and upgrading of adjacent candidate sites are compared to the pathogen's effector, and the adaptive immunity is directly or indirectly triggered again through the cloning, mutation and reproduction between candidate sites to realize the multiobjective equilibrium of the scheme. Taking 486,000 km2 of Sichuan Province as an example, MIA for LAFSS is simulated by the MATLAB platform. Based on the spring open source application framework of java platform, the cesiumjs map data is called through easyui, and the visualization of site selection scheme is presented with the terrain data of Map World as the background. The experimental results show that, compared with dynamic programming a

随着地理空间数据的获取方式的革新,无人机遥感测绘作为一种新兴的低成本、高精度、操作简便的遥感影像获取手段开始普及。其采集数据量大且成果数据极为丰富,对数据储存、管理、运算、分析、显示和描述都有着新的需求,因此其相关系统的设计与开发难度较大。目前主流软件均为桌面端的无人机数据处理和可视化软件,缺乏在线B/S架构系统。GIS(Geographic Information System)随着计算机科学技术的发展,尤其是Web GL技术的发展,正逐渐三维Web化,但又无法直接复用逐渐成熟的二维Web GIS方案。而无人机数据处理后产生正射影像拼接图、倾斜模型、点云、DEM等数据,满足了三维Web GIS平台的基础地理数据需求。因此随着云服务和云计算的发展,将无人机数据处理划分微服务融合集成在三维Web GIS平前后端并进行良好的可视化成为一个新的热点与难点问题。本文首先对国内外无人机数据处理相关系统研究现状、无人机数据处理相关系统建设的技术路线和方法进行了全面的归纳与总结。其次通过研究总结现有的三维Web GIS技术和无人机数据处理方案;再结合现有技术和方案,选择确定适用于三维Web GIS平台下无人机数据处理与传输系统的整体框架和各个模块的需求并进行设计。最后基于java spring为主框架开发了一款在线无人机数据传输系统,满足三维Web GIS前后端的需求。其中前端基于Vue框架和Cesium库实现三维地图渲染和交互操作;基于Nginx做静态服务和代理;后端基于java spring MVC规范服务并将Geo Server作为基础二维地图服务器,共同管理数据和发布地图服务;以Post GIS作为基础及空间数据库;采用Docker封装开源ODM(Open Drone Map)工具包提供为无人机影像数据处理功能,并基于java-Docker进行系统集成;采用ND4J、GDAL和Geo Tools做其余数据处理和部分算法开发;本系统整体以java spring-boot作为后端主框架进行数据库操作、算法整合、权限认证、三维数据发布接口等开发,通过切分微服务方便部署与扩展开发,可视化和部分业务逻辑及数据处理在前端中实现。系统脱离了原始桌面端系统处理无人机数据,人工导入GIS数据库的传统模式,为后续涉及无人机数据处理和可视化应用的三维Web GIS平台开发方案提供借鉴。

国家外管局推出了跨国公司外汇资金管理方式改革试点的九项措施，允许符合条件的跨国公司在现行委托贷款的法律框架下，以外汇头寸日内集中方式，对境内成员公司的外汇进行集中管理。由此推出了外汇虚拟账户管理系统，由集团公司对外汇头寸进行集中管理，本文对外汇资金管理的这一发展进行分析、阐述和设计实现。本文在比较了C／S，B／S架构的优缺点，以及java技术的最新发展后，系统架构决定使用B／S架构，并采用了java发展的前沿技术——spring架构。spring架构提供了一种相当灵活和可扩展的MVC实现，在依赖注入、AOP等方面表现优秀。确定了系统使用的架构后，对系统进行了需求分析，包括了外汇系统的功能分析和数据分析。由此进行了系统的整体设计和详细设计，阐述了外汇虚拟账户的建立、使用直到虚拟账户销户的一系列系统定义和操作流程，并最终实施运行。本文设计实现的虚拟账户管理系统用以帮助集团公司实现对其内部各部门资金的实时监控与管理，为集团公司业务部门在不能开立独立银行结算账户或集团公司不愿意过多开立银行结算账户情况下，提供一个集团公司内部资金管理平台。客户对集团外汇虚拟账户系统数据的准确性，安全性和时效性作了极高的评价，使我们对外汇虚拟账户系统的进一步扩展和扩大应用充满信心。
