Geoserver + mysql + openlayers problem

1. tomcat下部署geoserver解决跨域访问问题

报错：Access to XMLHttpRequest at 'http://localhost:8900/geoserver/cite/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=cite%3Apoi&maxFeatures=50&outputFormat=application%2Fjson' from origin 'http://localhost:8090' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

2. win10 处理shp数据进入mysql（报错cygwin1.dll丢失）

3. wfs要素url：

例：http://localhost:8900/geoserver/cite/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=cite%3Apoints&maxFeatures=50&outputFormat=application%2Fjsongeojson：
