错误信息

java.lang.RuntimeException: Fail to invoke getter org.nutz.el.opt.TwoTernary.'getLeft()' because [java.lang.NullPointerException]: null

错误产生：

public class IdEntity {
    @Id(auto = false)
    @Prev(els = @EL("$me.initId()"))
    @ColDefine(type = ColType.INT, width = 20)
    @Comment("主键")
    public long id;

    public long initId() {
             return 0L;
    }
}

这个idEntity只有进行json序列化就产生该异常。

把完整的堆栈贴出来,怎么我觉得不是id字段的错误

而是某个getXXX方法的问题

getLeft()的返回值是什么呢?
不过,最新的代码里面,已经放弃这种无声明的getter调用,改为主动声明

so, 你可以试试最新的代码

我们是用的 lombok来实现的自动产生get和set

你用了 @JsonField(getBy) ?? 贴出来?

没有用啊，我就是定义了一个那样的实体
@DaTa
public class IdEntity {
@id(auto = false)
@Prev(els = @el("$me.initId()"))
@Coldefine(type = ColType.INT, width = 20)
@comment("主键")
public long id;

public long initId() {
         return 0L;
}
private String name;

}
然后使用LoggingMethodInterceptor，将日志调成debug，然后return new IdEntity();
就出现了

我跟到最后发现，是调用了 MethodOpt对象的getLeft方法，但是MethodOpt根本没有getLeft方法。
我再问一个问题，如果设置了@el表达式，可不可以json的时候，不处理这个El表达式。
@id(auto = false)
@Prev(els = @el("$me.initId()"))
@Coldefine(type = ColType.INT, width = 20)
@comment("主键")
public long id;

@JsonField(getBy="xxx") 这个应该怎么填？

最后发现是Record.toString()过程中的异常
