做了一個簡單的基於Struts2 + Json + HighChart的小例子，費了一下午+晚上的時間，雖然簡單，但對於我這種Jquery+Ajax小白的人還是很值得記錄的。

哈哈哈

# 0. 關鍵點找到highchart的模板網站https://www.hcharts.cn/docs/basic-tooltip

# 1. 關鍵點，在struts.xml中配置傳回型別為json

<param name="root">dataMap</param>

</result>

# 2. 關鍵點2

public class JsonAction {
private Map<String, Object> dataMap;
public String jsonTest(){

dataMap = new HashMap<String,Object>();
dataMap.clear();
List<List<Float>> aveTimeForCpsWay = new ArrayList<List<Float>>();
for(int x=0;x<4;x++){
List<Float> temp = new ArrayList<Float>();
for(int i=0;i<12;i++){
temp.add((new Random().nextFloat())*100); // 隨機產生12個float數
}
aveTimeForCpsWay.add(temp);
}

List<String> name = new ArrayList<String>();
name.add("Tokyo");
name.add("New York");
name.add("London");
name.add("Berlin");

dataMap.put("dataArr", aveTimeForCpsWay);
dataMap.put("nameArr", name);

return "success";
}

public Map<String, Object> getDataMap() {
return dataMap;
}

public void setDataMap(Map<String, Object> dataMap) {
this.dataMap = dataMap;
}

}
