During the UI automation testing process, faced with complex business scenarios, we often encounter the following challenges: Simple recording/playback is fast, but cannot adapt to complex scenes; Writing automated test scripts is more flexible, but the workload is heavy and maintainability is poor; The previous encapsulation technology (PageObject) can adapt to various UI scenarios, but […]

java uses geotools to export shp files
The SHP format is a vector data format used to store geographic information system (GIS) data. SHP files consist of a series of ordered files. The shp files we export include .shp, .shx, .dbf, .prj and .fix files. .shp (shape) file: stores vector map data and records the spatial location information of each feature. .shx […]

java gets the city based on IP GeoLite2-City.mmdb
This article can solve the problem of not being able to obtain the IP location. It provides a variety of methods for reference only: 1. Selection 1.1 Implementation method Java can implement IP address resolution and province and city information query, but it requires the help of some external data sources or databases to achieve […]

The solution to the cross-domain problem when the front-end accesses the geoserver service, and the use of html2canvas to download the drawn map
My business scenario: You need to use html2canvas to download the map drawn by Openlayers. Expectation: Can be downloaded as images or even other formats (svg) files. Result: The download is a blank image. Troubleshooting errors: The request data is echoed to the page normally. When intercepted using html2canvas, cross-domain will occur, resulting in the […]
