Question

我正在尝试在Facelets文件的表格中显示JSONObject。我怎样才能做到这一点？

package com.myportal.dashboard;

import javax.annotation.PostConstruct;
import net.sf.json.JSONObject;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.web.context.WebApplicationContext;

@Component
@Scope(value=WebApplicationContext.SCOPE_SESSION)
public class DashboardBacker {

    private JSONObject dashboardTable;

    @PostConstruct
    public void initializeTable() {
        dashboardTable.put("Completed", 26);
        dashboardTable.put("Failed", 33);
        dashboardTable.put("In Progress", 44);
        dashboardTable.put("On-hold", 9);
    }

    public JSONObject getDashboardGraphs() {
        return dashboardGraphs;
    }

}

Answer 1

将json对象转换为字符串并将其设置为beans属性，如下所示：

String myJson = null; //getter / setter

@PostConstruct
public void initializeTable() {
    ....
    myJson = dashboardGraphs.toString();
    //myJson = new Gson().toJson(dashboardGraphs); //in case of Gson usage
}

比你的xhtml

然后在你的js代码中使用输入id $（＆＃39;＃my-json-holder＆＃39;）来访问它.val（）
