@zzutligang 1K也不算大，你上面业务对象也不大，就算循环了，并发不大的情况下也可以正常渲染JSON，内存可以算出来的。虽然是业务问题，但JF已经考虑到了
2023-09-06 10:43
@zzutligang 防止业务死循环，上面对象套对象，如果有两个相互是对方父级，那么转JSON字符串的时候就相互调用了，JVM就GG了
2023-09-05 22:48
@zzutligang [ 是一层，{ 也是一层，所以 数组 套 map 是两层。并不是只算 { map对象

我也懵逼，要不贴点代码？我测试没问题呀
public static void main(String[] args) {
Okv base = null;
Okv dad = null;
String[] kin = {"媳妇", "弟弟", "妹妹"};
List<String> riches = Arrays.asList(new String[]{"房子", "车子", "票子"});
for (int i = 0; i <= 20; i++) {
Okv son = Okv.of("name", "杜" + i);
son.set("kin", kin);
son.set("riches", riches);
if (base == null){
base = son;
}else {
dad.set("son", son);
}
dad = son;
}
JFinalJson.setDefaultConvertDepth(18);
String json = JFinalJson.getJson().toJson(base);
System.out.println(json);
}
{"name":"杜0","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜1","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜2","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜3","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜4","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜5","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜6","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜7","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜8","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜9","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜10","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜11","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜12","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜13","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜14","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜15","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜16","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜17","kin":["媳妇","弟弟","妹妹"],"riches":["房子","车子","票子"],"son":{"name":"杜18","kin":null,"riches":null,"son":null}}}}}}}}}}}}}}}}}}}

BigDecimal.class 已经内置，需要先移除再添加
Engine.removeExtensionMethod(BigDecimal.class, new BigDecimalExt());
Engine.addExtensionMethod(BigDecimal.class, new MyBigDecimalExt());

貌似 /src/main/webapp 目录下的前端文件没上传了。
Java代码很整洁，注释也很齐！个人用户很好的学习练手项目啊

@Leo.du 执行ActionHandler 的时候 才创建 JsonRequest对象，自定义的 Handler 是在ActionHandler 之前执行的，所以是拿不到的。
：
需求分析：根据你业务需求，是要获取 JsonRequest ，并且是 Handler 级的获取。
简单方案：创建JsonRequest 的时候，获取该对象，因为ActionHandler 支持setJsonRequestFactory。代码大致如下：JFinalConfig的子类》
public void configConstant(Constants me) {
me.setResolveJsonRequest(true);
me.setJsonRequestFactory((jsonString, req) -> {
JsonRequest ret = new JsonRequest(jsonString, req);
// 在这里 获取到这个对象
return ret;
});
}
：
复杂点方案：自定义ActionHandler，继承ActionHandler，复制里面代码，改为自己业务的，再配置：
public void configHandler(Handlers me) {
me.setActionHandler(...)
}

@hhchor 但是天笑分享的处理，就是有处理404返回的JSON呀。
除非是你Controller里面有index方法，这个是默认接收方法，如果里面代码没做返回数据处理的话，空的方法可能会返回异常RenderException。
最简单的就是里面不要写index方法。
当然以上为猜测，具体得看你代码是怎么写的了。比如是否有自定义ActionHandler之类的情况

需要解释一下什么叫做 “如果路径存在，Controller方法不存在”，方便的话，贴下代码

jfinal-undertow 开发下，src/main/resources/undertow.txt 文件里面加入一行配置：
### disable 是关闭不显示
undertow.serverName = disable
### 自定义比如
undertow.serverName = YunFinal
注意正式服一般会搭配NGINX代理，那么资源文件Server又会显示为NGINX了

要获取 Java 类的注解，可以使用 Java 的反射机制和注解 API。
如：注解类 a= 目标类.class.getAnnotation(注解类.class);
网上搜索资料时，直接搜索Java XXX 就可以了，不用加JFinal，除非是要扩展JF的功能。比如下面两个扩展：

因为分页有割掉order by,这种复杂的order by需要跳过一下,我之前有遇到过类似的需求,有加一个扩展处理进行跳过切割,
分享内容在: https://jfinal.com/share/2533
或者使用手册里面介绍的 https://jfinal.com/doc/5-6
第 "5、常见问题解决" 内容有介绍如何处理

@北流家园网 普通JavaBean，没啥内容，就是固定了属性字段，因为Kv等类的属性是set进去的动态的，而返回结构第一级是固定格式，每次写比较麻烦。
