You're defining cache with custom cache's name: slfV5_Cache. 
You may:
1. remove <property name="cacheName" value="slfV5_Cache" /> so the cache will 
have default name

or

2. use annotation @CacheName("slfV5_Cache") on each method annotated with SSM 
annotations: @ReadThrough*, @Update*, @Invalidate*, in the case on 
com.zxhz.web.TestController.testssm

i don't know where is error!

GoogleCodeExporter commented 9 years ago 
The error is self invocation, invoking ssm() method in con() method using 
'this' reference (the same object). Spring doesn't intercept self invocations, 
such invocation omits proxy so the SSM is not invoked. Move ssm() method to 
another bean: MyCache and inject the bean to bean with con() method.

so! 
This method has four parameters！
method :
public Object getSpec(int merId,String code,int type,httpservletrequest 
request){
       //TODO 
}

I want to use the three parameter as cache key

What should I do？

 Thank you very much! thanks a lot!

GoogleCodeExporter commented 9 years ago 
To create cache key using many parameters use @ParameterValueKeyProvider 
annotation:

@ReadThroughSingleCache(namespace = "spec", expiration = 3600)
public Object getSpec(@ParameterValueKeyProvider(order = 0) int merId, 
@ParameterValueKeyProvider(order = 1) String code, 
@ParameterValueKeyProvider(order = 2) int type,httpservletrequest request){
       //TODO 
}

No problem :).
Next time please use SSM's mailing group:
