Unit06： Spring对JDBC的 整合支持 、 Spring+JDBC Template 、Spring异常处理

1. springmvc提供的异常处理机制

我们可以将异常抛给spring框架，让spring来帮我们处理异常。

(1)使用简单异常处理器

step1. 配置简单异常处理器。

step2. 添加对应的异常处理页面。
注：该方式只适合处理简单异常的处理，如果要对异常做复杂处理，比如
记录日志等，则不合适了。

(2)使用@ExceptionHandler注解

step1. 在处理器类当中，添加一个异常处理方法，
该方法要使用@ExceptionHandler注解来标注。

step2.添加对应的异常处理页面。

2. SpringJdbc

(1)SpringJdbc是什么?

是spring框架中的一个模块，对jdbc api做了封装，简化了
jdbc的代码(比如，不用考虑获取连接与关闭连接了)

(2)编程步骤

step1. 导包。

step2. 添加spring配置文件。
step3. 添加JdbcTemplate配置。

注:JdbcTemplate对jdbc的api做了封装。
step4. 调用JdbcTemplate提供的方法。
注：通常将JdbcTemplate注入到DAO。
