如何在使用Lombok生成的IntelliJ IDEA中的setter方法中设置断点？ [英] How to set a breakpoint in a setter method in IntelliJ IDEA that is generated with Lombok?

问题描述

在由 Lombok 生成的setter方法中， IntelliJ IDEA 中是否有设置断点的方法？

这对于某些调试场景非常有用，例如看看何时从Hibernate这样的框架中调用setter。实际上，生成的setter方法显示在IntelliJ IDEA（正在使用的Lombok插件）的结构视图中， 。但我还没有找到通过上下文菜单或类似的方法设置断点的方法。

解决方案

在我的理解中，这样做是因为lombok以突变的代码没有自动生成的零件的行号的方式突变字节码。

这样做的目的是始终有你的源代码行匹配你的字节码。它们不匹配，当你将断点放在一行上但是执行没有停止或停止在其他地方（因为行号不匹配），你可能会陷入困境。

但是作为交换，Lombok失去了调试生成代码的能力（不能在没有行号的行上放置断点）。您必须依赖生成的代码正确的事实。

Is there a way in IntelliJ IDEA to set a breakpoint in a setter method that is generated by Lombok?

This would be very useful in certain debugging scenarios, e.g. to see when the setter is called from a framework like Hibernate.

In fact, the generated setter methods are displayed in the structure view of IntelliJ IDEA (Lombok plugin in use). But I've not found a way to set a breakpoint via the context menu or such.

解决方案

In my understanding you can't do that because lombok is mutating your bytecode in a way that mutated code doesn't have line numbers for auto-generated parts.

This is done on purpose to always have your source code lines match your bytecode. It they doesn't match, you'll may get caught in a situation when you placing your breakpoints on a line but execution didn't stop or stops somewhere else (because of line numbers mismatching).

But in exchange Lombok loses the ability to debug generated code (you can't place breakpoint on a line without line number). You have to rely on a fact that generated code is correct.
