Wie verwende ich Java-Objekte, um komplexes JSON darzustellen?

Es gibt ein JSON-Objekt, das häufig verwendet werden muss, daher möchte ich es in ein Objekt kapseln,

{tooltip : { trigger: 'axis', axisPointer: {type: 'cross',}, formatter: "{b}: {c})"}, xAxis :{ type : 'category', data : ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'], axisTick: {alignWithLabel: true}}, yAxis :{ type : 'value'}, series :{ type:'bar', barWidth: '80%', data:[10, 52, 200, 334, 390, 330, 220]}}

Die aktuelle Idee besteht darin, eine Ebene mit Objekten und dann eine weitere Ebene mit Tooltip-, xAxis- und Serienobjekten zu haben, aber das ist völlig daneben, es ist nur ein Hilfsobjekt. Gibt es gute Praktiken?

虽然并没有太理解你的问题,不过针对json去写一些类表示这个json的结构,是有点烦...不过有个神器可以帮你简单解决这个问题,哈哈

IDEA里有个神器叫GsonFormat

这个插件处理json十分好用,不管json有多复杂,只要json格式正确,自动帮你生成类,哈哈

一般使用步骤是这样的:

  1. 新建一个类,比如叫Test,这个类就是你最后要使用的类

  1. 然后Alt+s 打开GsonFormat的快捷键

  1. 把要转换的json字符串粘贴进去,点ok

4.确认转换后的格式和类型,基本默认都可以的,直接点ok即可

  1. 类生成:

public class Test { /** * tooltip : {"trigger":"axis","axisPointer":{"type":"cross"},"formatter":"{b}: {c})"} * xAxis : {"type":"category","data":["Mon","Tue","Wed","Thu","Fri","Sat","Sun"],"axisTick":{"alignWithLabel":true}} * yAxis : {"type":"value"} * series : {"type":"bar","barWidth":"80%","data":[10,52,200,334,390,330,220]} */ private TooltipBean tooltip; private XAxisBean xAxis; private YAxisBean yAxis; private SeriesBean series; public TooltipBean getTooltip() { return tooltip; } public void setTooltip(TooltipBean tooltip) { this.tooltip = tooltip; } public XAxisBean getXAxis() { return xAxis; } public void setXAxis(XAxisBean xAxis) { this.xAxis = xAxis; } public YAxisBean getYAxis() { return yAxis; } public void setYAxis(YAxisBean yAxis) { this.yAxis = yAxis; } public SeriesBean getSeries() { return series; } public void setSeries(SeriesBean series) { this.series = series; } public static class TooltipBean { /** * trigger : axis * axisPointer : {"type":"cross"} * formatter : {b}: {c}) */ private String trigger; private AxisPointerBean axisPointer; private String formatter; public String getTrigger() { return trigger; } public void setTrigger(String trigger) { this.trigger = trigger; } public AxisPointerBean getAxisPointer() { return axisPointer; } public void setAxisPointer(AxisPointerBean axisPointer) { this.axisPointer = axisPointer; } public String getFormatter() { return formatter; } public void setFormatter(String formatter) { this.formatter = formatter; } public static class AxisPointerBean { /** * type : cross */ private String type; public String getType() { return type; } public void setType(String type) { this.type = type; } } } public static class XAxisBean { /** * type : category * data : ["Mon","Tue","Wed","Thu","Fri","Sat","Sun"] * axisTick : {"alignWithLabel":true} */ private String type; private AxisTickBean axisTick; private List data; public String getType() { return type; } public void setType(String type) { this.type = type; } public AxisTickBean getAxisTick() { return axisTick; } public void setAxisTick(AxisTickBean axisTick) { this.axisTick = axisTick; } public List getData() { return data; } public void setData(List data) { this.data = data; } public static class AxisTickBean { /** * alignWithLabel : true */ private boolean alignWithLabel; public boolean isAlignWithLabel() { return alignWithLabel; } public void setAlignWithLabel(boolean alignWithLabel) { this.alignWithLabel = alignWithLabel; } } } public static class YAxisBean { /** * type : value */ private String type; public String getType() { return type; } public void setType(String type) { this.type = type; } } public static class SeriesBean { /** * type : bar * barWidth : 80% * data : [10,52,200,334,390,330,220] */ private String type; private String barWidth; private List data; public String getType() { return type; } public void setType(String type) { this.type = type; } public String getBarWidth() { return barWidth; } public void setBarWidth(String barWidth) { this.barWidth = barWidth; } public List getData() { return data; } public void setData(List data) { this.data = data; } } }

    import java.util.HashMap; import java.util.Map; import com.alibaba.fastjson.JSON; public class MM { class Tooltip { private String trigger; private Map axisPointer; private String formatter; public String getTrigger() { return trigger; } public void setTrigger(String trigger) { this.trigger = trigger; } public Map getAxisPointer() { return axisPointer; } public void setAxisPointer(Map axisPointer) { this.axisPointer = axisPointer; } public String getFormatter() { return formatter; } public void setFormatter(String formatter) { this.formatter = formatter; } } public static void main(String[] args) { MM mm = new MM(); Tooltip tooltip = mm.new Tooltip(); tooltip.setTrigger("axis"); tooltip.setAxisPointer(new HashMap(){{ this.put("type", "cross"); }}); tooltip.setFormatter("{b}: {c})"); Map map = new HashMap(); map.put("tooltip", tooltip); System.out.println(JSON.toJSONString(map)); } }

    输出:

    {"tooltip":{"axisPointer":{"type":"cross"},"formatter":"{b}: {c})","trigger":"axis"}}
