好久沒用GIT，再次撿起來，遇到了些錯誤，比如沒寫comment，導致沒提交成功，沒有先從遠端pull，導致沒push成功。

於是將這個過程記錄如下：

1：首先，跳轉到專案根目錄
2：檢視當前狀態

3：把我們要提交的檔案的資訊新增到索引庫中

4： 提交檔案到本地庫

5：合併到遠端程式碼庫（首先要將遠端庫，pull到本地，否則不能push）

5.1：沒有將遠端庫pull到本地，報錯：

6：pull遠端到本地

7：設定 git ignore 過濾檔案，.class 字尾檔案不提交到遠端

8：再次push，成功

具體如下：

1:首先，跳轉到專案根目錄
[email protected] /e/abc
$ cd CanYin-www

[email protected] /e/abc/CanYin-www (master)
$ ls
LICENSE  README.md  pom.xml  src  target
2：檢視當前狀態
$ git status;
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

        modified:   src/main/java/cn/canyin/dao/MenuDao.java
        ...

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        src/main/java/cn/canyin/dao/Dao.java
        ...

no changes added to commit (use "git add" and/or "git commit -a")

3: 把我們要提交的檔案的資訊新增到索引庫中
[email protected]

4: 提交檔案
[email protected] /e/abc/CanYin-www (master)
$ git commit -a   #注意這一步要寫comment
[master dfce490] add menu model, changed by jonsanguo at 20140408

7：設定 git ignore 過濾檔案，.class 字尾檔案不提交到遠端
$ echo *.class>.gitignore
檢視設定是否成功：
$ cat .gitignore
*.class

8：再次push，成功
