1.使用maven管理工具，避免手動導入jar包的麻煩。而且手動導入也可能存在版本不匹配的問題。
所以pom.xml如下（提供了搭建ssm基礎的所有jar包）

jdbc.password=123456
（8）自身遇到的問題和注意
學習筆記；
1.使用了spring批量加載mapper的話，就已經會創建mapper對象了，不用再配置組件掃描了。
2.以屬性的方式注入了對象的話，最好提供set和get方法。
3.如果發現掃描對象無法創建，考慮是否是web.xml文件沒生效的原因。
4.bean的創建時間，是在掃描之後就會創建。
5.一般不用autowired，而用resource。因爲後者可控，具有name屬性。
6.生成一個註解對象，最好在註解位置加上（value="xxx"）方便調用。
9.補充：如果要使用json視圖的話，還要在pom.xml中加上下面的代碼
