geotool案例1，快速显示shapefile

1、初始化maven项目，pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

2、源码，直接放在main函数中运行

// 调用文件对话框，获取shp文件
File file = JFileDataStoreChooser.showOpenFile("shp", null);
if (file == null) {
    return;
}

// 存储文件变量为简单要素源变量
FileDataStore store = FileDataStoreFinder.getDataStore(file);
SimpleFeatureSource featureSource = store.getFeatureSource();

// 创建地图变量，设置标题、样式、图层
MapContent map = new MapContent();
map.setTitle("Quickstart");

Style style = SLD.createSimpleStyle(featureSource.getSchema());
Layer layer = new FeatureLayer(featureSource, style);![在这里插入图片描述](https://img-blog.csdnimg.cn/20200119172116293.png?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21jMGNzZG4wMjAxNQ==,size_16,color_FFFFFF,t_70)
map.addLayer(layer);

// 窗体显示地图
JMapFrame.showMap(map);
