In Eclipse, I've enabled intellisense-style suggestions for Java by going to

在 Eclipse 中，我通过以下方式为 Java 启用了智能感知风格的建议

Window -> Preferences -> Java/Editor/Content Assist

and setting the following

并设置以下内容

Auto activation delay (ms) -> 0
Auto activation triggers for Java -> .(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

source = Eclipse Intellisense?

源 = Eclipse 智能感知？

This works brilliantly, apart from one annoying problem. When I hit spacebar, the token being typed is autocompleted with whatever is at the top of the suggestions list. Fair enough, except that sometimes I'll type a class/variable name with an exact legal match, but this won'tappear as the top suggestion. So when I naturally hit spacebarEclipse inserts something completely wrong.

除了一个烦人的问题外，这非常有效。当我点击 时spacebar，输入的标记会自动完成，并使用建议列表顶部的任何内容。很公平，除了有时我会输入一个具有完全合法匹配的类/变量名称，但这不会作为最重要的建议出现。所以当我自然而然地点击spacebarEclipse 时，插入了一些完全错误的东西。

E.G.after typing CookieI'll hit spacebarand get CookieMonster.

EG打字后Cookie我会打spacebar并得到CookieMonster。

This seems like a bug, and happens often enough to be annoying, but even despite this I don't want spacebarto trigger autocomplete in general. I may want to type a variable name which hasn't been declared yet, or something similar. I want to use autocomplete as a helper tool, but my natural typing should alwaystake priority over it.

这似乎是一个错误，并且经常发生令人讨厌，但即使如此，我也不想spacebar触发自动完成。我可能想输入一个尚未声明的变量名，或者类似的东西。我想使用自动完成作为辅助工具，但我的自然打字应始终优先于它。

I'd like to stop spacebartriggering autocomplete, and either fall back to using enter, or better still trigger autocomplete with a customkey not used in ordinary typing. Is any of this possible?

我想停止spacebar触发自动完成，要么回退到 using enter，要么最好仍然custom使用普通打字中不使用的键触发自动完成。这有可能吗？

I've played around with all the settings in Content Assistto no avail. Googling the question just returns a bunch of results about disabling the autocomplete feature.

我已经尝试了Content Assist 中的所有设置，但无济于事。谷歌搜索这个问题只会返回一堆关于禁用自动完成功能的结果。

You now have a new option to disable all insertion triggers apart from enter, which will prevent spacebarfrom causing autocompletion.

您现在有一个新选项可以禁用除 之外的所有插入触发器enter，这将防止spacebar导致自动完成。

Simply go to Preferences...-> Java-> Editor-> Content Assist(or Window-> Preferences-> Java-> Editor-> Content Assiston Windows) and select Disable insertion triggers except 'Enter', as shown in the screenshot below:

The spacebar has been a key to select the autocomplete even in Indigo. To my knowledge, this can't be configured. In fact, that is probably why the delay exists.

即使在 Indigo 中，空格键也是选择自动完成的关键。据我所知，这是无法配置的。事实上，这可能就是延迟存在的原因。

I suggest setting the delay to some optimal value that allows you to type things like private void ...comfortably without triggering suggestions for privateand void. Then in case you get a suggestion because you waited too long, press Escape to abort Content Assist.

我建议设置延迟一些最佳值，可以让你型喜欢的东西private void ...舒服，而不会触发的建议private和void。然后，如果您因为等待时间过长而收到建议，请按 Escape 中止 Content Assist。

Same configuration as davnicwil, same issue, still on eclipse 4.4.

与 davnicwil 相同的配置，相同的问题，仍在 eclipse 4.4 上。

Solution: Intercept (hook) SHIFT+SPACE (press and hold) on (editor-window) eclipse and replace it with ESC,SPACE (sequence). Now you my decide between

解决方案：在（编辑器窗口）eclipse 上截取（挂钩）SHIFT+SPACE（按住）并将其替换为 ESC,SPACE（序列）。现在你我决定

• Autocomplete+SPACE: press SPACE when autosuggestion present
• just SPACE: press predefined key combination or sequence (e.g. SHIFT+SPACE)

• 自动完成+空格：出现自动提示时按空格键
• 只是空格：按预定义的组合键或序列（例如 SHIFT+SPACE）
