xsd解析

1.  解释：

<xsd:element name="interceptors">
		<xsd:annotation>  这一块是对第一行的注解（解释）
			<xsd:documentation><![CDATA[
	The ordered set of interceptors that intercept HTTP Servlet Requests handled by Controllers.
	Interceptors allow requests to be pre/post processed before/after handling.
	Each inteceptor must implement the org.springframework.web.servlet.HandlerInterceptor or
	org.springframework.web.context.request.WebRequestInterceptor interface.
	The interceptors in this set are automatically configured on each registered HandlerMapping.
	The URI paths each interceptor applies to are configurable.
			]]></xsd:documentation>
		</xsd:annotation>			
		<xsd:complexType>  表示一个复合类型
			<xsd:choice maxOccurs="unbounded">
				<xsd:element ref="beans:bean"> 表示可以是一个bean标签
					<xsd:annotation> 对上一行的注解
						<xsd:documentation source="java:org.springframework.web.servlet.handler.MappedInterceptor"><![CDATA[
	Registers an interceptor that intercepts every request regardless of its URI path.
						]]></xsd:documentation>
					</xsd:annotation>
				</xsd:element>
				<xsd:element name="interceptor"> 表示可以是一个interceptor标签
					<xsd:annotation>  对上一行的注解
						<xsd:documentation source="java:org.springframework.web.servlet.handler.MappedInterceptor"><![CDATA[
	Registers an interceptor that interceptors requests sent to one or more URI paths.
						]]></xsd:documentation>
					</xsd:annotation>
					<xsd:complexType> 表示是一个复合类型
						<xsd:sequence> 表示下面的配置是有顺序的
							<xsd:element name="mapping" maxOccurs="unbounded"> 可以添加mapping标签
								<xsd:complexType> 表示是一个复合类型
									<xsd:attribute name="path" type="xsd:string" use="required"> 表示是一个path标签，类型string，必须的
										<xsd:annotation>
											<xsd:documentation><![CDATA[
	A path into the application intercepted by this interceptor.
	Exact path mapping URIs (such as "/myPath") are supported as well as Ant-stype path patterns (such as /myPath/**).
											]]></xsd:documentation>
										</xsd:annotation>
									</xsd:attribute>								
								</xsd:complexType>
							</xsd:element>
							<xsd:element ref="beans:bean">  bean标签
										<xsd:annotation> 注解
											<xsd:documentation><![CDATA[
	The interceptor‘s bean definition.
											]]></xsd:documentation>
										</xsd:annotation>							
							</xsd:element>						
						</xsd:sequence>
					</xsd:complexType>			
				</xsd:element>
			</xsd:choice>
		</xsd:complexType>
</xsd:element>

2. 上面文档的例子：

<mvc:interceptors>
    <mvc:interceptor>
       <mvc:mapping path="/xxx/**" />
       <bean class="xxxx.xxInterceptor" />
    </mvc:interceptor>
</mvc:interceptors>
