请教高手们我遇到的一个spring acegi的奇怪问题

Security的配置文件中有一个<bean id="filterInvocationInterceptor" class="org.acegisecurity.intercept.web.FilterSecurityInterceptor">Spring知道filterSecurityInterceptor的objectDefinitionSource属性的类型为FilterInvocationDefinitionSource，查找该类型的编辑器FilterInvocationDefinitionSourceEditor
我看了一下FilterInvocationDefinitionSourceEditor的源代码.其中只有一个方法public void setAsText(String s) throws IllegalArgumentException
这个参数S便是<property name="objectDefinitionSource">中<value>的值.其中 BufferedReader br = new BufferedReader(new StringReader(s));
String line;
line = br.readLine();
他把配置的value逐行的读出来.然后把地址和权限逐个截取set到相应的类中
一下是我的配置文件

        </property>不知道为什么现在只能截取到第7行为止.如果没有具有相应权限的角色都可以任意进入第7行一下的任何一个地址
