一。若发现内容辅助失效没有提示 下面是解决办法，现贴出来与大家共享：
1、菜单window->Preferences->Java->Editor->Content Assist->Enable auto activation 选项要打上勾
2、windows-->preference-->workbench-->keys 下设置Content Assist 的快捷键
3、window->Preferences->Java->Editor->Content Assist->Advanced 上面的选项卡Select the proposal kinds contained in the 'default' content assist list: 中把 Other Java Proposals 选项打上勾就可以了。
使用中文Eclipse的请看下面：
1、菜单->窗口->首选项->Java->编辑器->内容辅助>启用自动激活
2、窗口-->首选项-->工作空间-->键 ->恢复默认值
3、窗口->首选项->Java->编辑器->内容辅助>高级 上面的选项卡 选择“缺省”内容辅助列表中包含的建议类型 中把 其它建议 选项打上勾就可以了。
二。Eclipse内容辅助默认的快捷键是Alt+/ 若不喜好老按Alt+/ 可以设置如下 让你在编写java文件时候
1.打开 Eclipse -> Window -> Perferences，在Perferences 的设置界面。
会看到只有一个"."存在。表示：只有输入"."之后才会有代码提示，我们要修改的地方就是这里，可是Eclipse默认只允许输入4个自定义字符。
2.不过我们可以把当前的设置导出，保存为一个文件，然后在文件中修改，再导入设置，这样就可以突破Eclipse的限制。先把上图中"."的地方输入几个随便的字符，例如"asdf"，点最下面的"OK"来保存设置。然后打开 Eclipse的 File -> Export,在窗口中展开 General -> Perferences—>Export all然后点击 NEXT。然后点击"Browse"选择任意的一个路径，保存配置文件，然后点击"Finish"。
3.用记事本打开刚才保存的那个配置文件（扩展文件名：*.epf），按"ctrl +F"，输入刚才设置的"asdf"，找到刚才字符串。把"asdf"修改为"abcdefghijklmnopqrstuvwxyz."，然后保存，退出记事本。
4.打 开Eclipse的 File -> Import 然后在打开的窗口里展开 General –>Perferences，点击NEXT，选中刚才修改过的配置文件，Finish。现在，再打开Window ->Perferences，并依次展开 Java -> Editor –> Content Assist，会发现已经超过了4个字符，也就是说我们输入任何字母和"."都会有代码提示了。
