### 版本为2019.02版 ###

### 一、IDEA标签Tabs多行显示 ###

当打开页面太多的时候，标签页会折叠，想要看代码不方便，只能点击右上角才能看到代码文件  
![在这里插入图片描述][20191108145823468.png]![在这里插入图片描述][2019110814575394.png]

在file中，点击settings

依次打开Editor–>General -->Editor Tabs，把show tabs in one row的勾去掉，这样就可以多行显示代码了。另外，可以自由选择Tab limit，这是Tab的个数，个人设置为20-30基本就够用了。

### 二、分屏显示代码 ###

### 三、使用git查看文件的每个部分是谁修改的 ###

文件右击，选择Git，然后点击Annotate

左边就能看到提交时间和提交者

### 四、使用ALT复制IDEA 提示框内信息 ###

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 4]  
想要复制IDEA提示框的信息最好的方法是，按CTRL+F1 （show inspection description）显示全部之后 按ALT+鼠标左键点击 然后 就可以粘贴(Ctrl + V)了  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 5]

### 五、IDEA 同步Eclipse代码格式化详解 ###

### 六、设置默认不折叠一行的方法 ###

IDEA，一行的方法默认是折叠的。  
File->Setting->Editor->General->Code Folding，把红色部分取消掉即可  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 6]

### 七、Tab按照打开顺序排列 ###

IEDA打开文件后，Tab排序是按照文件名排序的，这一点，让人很抓狂，大部分人习惯按照打开顺序排序。博主摸索了一下，发现了一个设置就可以了。点击File->Editor->General->Editor Tabs，选择Open new tabs at the end，这样打开的文件就可以按照打开顺序排列了。（另外，可以选择Most recently opened tab最近打开的tab），个人习惯，关闭tab的时候，打开最近打开的tab  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 7]

### 八、看Java类图（Java Class Diagram） ###

右击该类，选择Diagrams -> Show Diagram，即可打开类图  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 8]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 9]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 10]  
通过类图，我们对这些类的继承关系一目了然  
还可以调整布局。在类图上点击右键，选择"Layout"，在子菜单中可以调整排列效果  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 11]  
选择“Orthogonal Layout”的效果如下

### 九、常用快捷键 ###

alt+shift+c 改方法名和参数  
ctrl+alt+h 查看该方法被谁调用  
alt+shift+m 重构方法

### 十、清理缓存 ###

有时候，内存占用多了，代码多了，一些类突然就识别不了，清理一下缓存就可以了  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2V4b2R1czM_size_16_color_FFFFFF_t_70 14]

### 十一、忽略大小写提示 ###
