5.1 从目录扫描文件输出
配置文件error-config.xml，其中很多地方做了些调整
<!-- spring管理的bean -->
<spring:bean id="errorManager"
/>
<spring:ref local="defaultHandler" />
<spring:ref local="businessHandler" />
</spring:list>

<spring:bean id="defaultHandler"

<spring:property name="errorManager">
<spring:ref local="errorManager" />
</spring:property>
</spring:bean>
<!-- 严重错误异常，输出到邮件 -->
<spring:bean id="fatalHandler"
value="ExceptionEmailer" />
<spring:property name="errorManager">
<spring:ref local="errorManager" />
</spring:property>
</spring:bean>
<!-- 业务异常处理，输出到队列 -->
<spring:bean id="businessHandler"

<spring:property name="errorManager">
<spring:ref local="errorManager" />

</spring:bean>

</service>
</model>
对于component和pooled-component还有待认识。
这个示例中有spring bean的配置，同时有邮箱smtp协议，jms等的调用。
