对于未检查和检查的异常，一个简单的示例是

 <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<property name="exceptionMappings">
  <map>
    <entry key="DataAccessException" value="data-error" />
    <entry key="com.stuff.MyAppRuntimeException" value="app-unchecked-error" />
    <entry key="com.stuff.MyAppCheckedException" value="app-checked-error" />
  </map>
</property>
<property name="defaultErrorView" value="general-error"/>
</bean>
