<blockquote>
<p> 我们有两种整合方法:</p>
<ul>
<li>
<p>①同时配置Spring IOC和Spring MVC IOC</p>
<blockquote>
<p> 通常情况下, 我们都是配置两个IOC容器的.</p>
<ul>
<li>将类似于数据源、事务、 整合其他框架的配置都是放在 Spring 的配置文件中, 还有 Service 和 Dao 对象等.</li>
<li>而 Spring MVC 的 IOC 只负责HandlerMapping 映射策略、各种 Controller 控制器、各种视图解析、拦截器、LocalResolver 国际化处理等的配置.</li>
</ul>
</blockquote>
</li>
<li>
<p>②只配置Spring MVC IOC: 将所有配置都放在 SpringMVC 的配置文件中. 也可以分多个 Spring 的配置文件, 然后使用 import 节点导入其他的配置文件.</p>
</li>
<li>
<p><font style="color:red;">在这里, 我们用第①种方法.</font></p>

<li>

<h2 id="4-配置各自IOC的xml">4.配置各自IOC的xml</h2>
<p><font style="color:red;font-weight:bolder;">注意: 以下所有的配置文件, 均在项目的 classpath 下.</font></p>
<blockquote>
<p> 这里我们是创建了两个 IOC, 需要配置两个 xml 文件: spring.xml 和 spring-mvc.xml.</p>
<p>首先, 他们两个所做的功能不同, 故需要扫描加载不同的 Class.</p>
<p>一个指定扫描包, 一个排除扫描包.</p>
<p>注意: 指定扫描时, 需要设置属性<code>use-default-filters="false"</code>.</p>
