Java调用echarts提供的地图压缩方法来压缩地图
今天小编就为大家分享一篇关于Java调用echarts提供的地图压缩方法来压缩地图，小编觉得内容挺不错的，现在分享给大家，具有很好的参考价值，需要的朋友一起跟随小编来看看吧由于默认情况下的 geojson 文件太大，echarts 提供了方法可以压缩地图。
geojson 介绍：http://geojson.org/
echarts 提供了压缩算法，但是代码是 javascript 的，参考代码写个 java 的也可以，但是通过 java 提供的脚本引擎可以很方便的直接执行 js。
本文压缩代码参考下面的项目：
https://github.com/giscafer/mapshaper-plus
这里的算法也是来源于 echarts
从该项目提取出压缩地图的 js 代码，简化后如下：
function convert2echarts(rawstr,filename,type){
var results="";
var json = json.parse(rawstr);
// meta tag
json.utf8encoding = true;
var features = json.features;
if (!features) {
return;
}
features.foreach(function (feature){
var encodeoffsets = feature.geometry.encodeoffsets = [];
var coordinates = feature.geometry.coordinates;
if (feature.geometry.type === 'polygon') {
coordinates.foreach(function (coordinate, idx){
coordinates = encodepolygon(
coordinate, encodeoffsets = []
);
});
} else if(feature.geometry.type === 'multipolygon') {
coordinates.foreach(function (polygon, idx1){
encodeoffsets = [];
polygon.foreach(function (coordinate, idx2) {
coordinates = encodepolygon(
coordinate, encodeoffsets = []
);
});
});
}
});
if(type==='json'){
results=json.stringify(json);
}else{
results=addechartsjswrapper(json.stringify(json), filename);
}
return results;
};
function encodepolygon(coordinate, encodeoffsets) {
var result = '';
var prevx = quantize(coordinate);
var prevy = quantize(coordinate);
// store the origin offset
encodeoffsets = prevx;
encodeoffsets = prevy;
for (var i = 0; i < coordinate.length; i++) {
var point = coordinate;
result+=encode(point, prevx);
result+=encode(point, prevy);
prevx = quantize(point);
prevy = quantize(point);
}
return result;
}
function addamdwrapper(jsonstr) {
return ['define(function() {',
'return ' + jsonstr + ';',
'});'].join('\n');
}
function addechartsjswrapper(jsonstr,filename) {
return ['(function (root, factory) {',
"if (typeof define === 'function' && define.amd) {",
" define(['exports', 'echarts'], factory);",
"} else if (typeof exports === 'object' && typeof exports.nodename !== 'string') {",
" factory(exports, require('echarts'));",
"} else {",
" factory({}, root.echarts);",
"}",
" }(this, function (exports, echarts) {",
" var log = function (msg) {",
" if (typeof console !== 'undefined') {",
" console && console.error && console.error(msg);",
" }",
" }",
" if (!echarts) {",
" log('echarts is not loaded');",
" return;",
" }",
" if (!echarts.registermap) {",
" log('echarts map is not loaded')",
" return;",
" }",
" echarts.registermap('"+filename+"',"+ jsonstr,
' )}));'].join('\n');
}
function encode(val, prev){
// quantization
val = quantize(val);
// var tmp = val;
// delta
val = val - prev;
if (((val << 1) ^ (val >> 15)) + 64 === 8232) {
//wtf, 8232 will get syntax error in js code
val--;
}
// zigzag
val = (val << 1) ^ (val >> 15);
// add offset and get unicode
return string.fromcharcode(val+64);
// var tmp = {'tmp' : str};
// try{
// eval("(" + json.stringify(tmp) + ")");
// }catch(e) {
// console.log(val + 64);
// }
}
function quantize(val) {
return math.ceil(val * 1024);
}

下面使用 java 8 中的脚本引擎执行该代码。
package tk.mybatis;
import javax.script.invocable;
import javax.script.scriptengine;
import javax.script.scriptenginemanager;
import javax.script.scriptexception;
import java.io.filenotfoundexception;
import java.io.filereader;
public class encoder {
public static final scriptengine engine = new scriptenginemanager().getenginebyname("nashorn");
static {
try {
//注意这里的 encode.js 路径，文件内容就是上面的 js 代码
engine.eval(new filereader(encoder.class.getresource("/encode.js").getpath()));
} catch (scriptexception e) {
e.printstacktrace();
} catch (filenotfoundexception e) {
e.printstacktrace();
}
}
public static final invocable invocable = (invocable) engine;
/**
* 压缩为 echarts 格式的地图
* @param geojson
* @param filename
* @param type json 或 其他（按js处理）
* @return
*/
public static string convert2echarts(string geojson, string filename, string type) {
try {
return (string) invocable.invokefunction("convert2echarts", geojson, filename, type);
} catch (scriptexception e) {
throw new runtimeexception(e);
} catch (nosuchmethodexception e) {
throw new runtimeexception(e);
}
}
}
用法：
string json = encoder.convert2echarts(
"上面提供的河北省的geojson内容", "河北省", "json");
压缩后的结果如下（文件大小为 9 kb）：
