最近在弄个项目，需要远程调用接口，用了Spring HttpInvoke，遇到下面问题
: Could not access HTTP invoker remote service at [http://127.0.0.1:8080/NRMP/SyncRemoteService]; nested exception is : invalid stream header: 0D0A0D0A

最后弄了两天终于找到原因了。
原来是spring mvc url认证拦截了导致错误的，就是下面这个配置
<!-- Shiro 过滤器 -->
<bean class="" depends-on="systemFilter">
<property name="securityManager" ref="securityManager" />
<property name="loginUrl" value="/login" />
<property name="successUrl" value="/" />
<property name="unauthorizedUrl" value="/403" />
<property name="filters">
<map>
<entry key="systemFilter" value-ref="systemFilter"/>
</map>
</property>
<property name="filterChainDefinitions">
<value>
/static/** = anon
/login = authc
/machine/** = anon
/machineSend/** = anon
/SyncRemoteService = anon
/** = authc,systemFilter
/sys/** = user
/res/** = user
</value>
</property>
</bean>
解决办法 ，将远程调用接口url排除在外就解决问题 加上这么一句 /SyncRemoteService = anon 就可以了
