 ## Project Architecture ##
 
 Both extension module and layered project architecture is according to Apache Dubbo (including protocol layer, registry layer, cluster layer, config layer and so on), the advantage of this arch is as following: you can implement these layered interfaces in your own way, override the default implementation of dubbo-go by calling 'extension.SetXXX' of extension, complete your special needs without modifying the source code. At the same time, you are welcome to contribute implementation of useful extension to the community.

-Examples of dubbo-go
-
-## What does this contain
-
-* helloworld
-
-    A simplest example. It contain 'go-client', 'go-server', 'java-server' of dubbo protocol. 
-
-* general
-
-    A general example. It had validated zookeeper registry and different parameter lists of service. 
-  And it has a comprehensive testing with dubbo/jsonrpc protocol. You can refer to it to create your first complete dubbo-go project.
-
-* generic
-
-    A generic reference example. It show how to use generic reference of dubbo-go.
-
-* configcenter
-
-    Some examples of different config center. There is only one -- zookeeper at present.
-
-## How to build and run
-
-> Take `helloworld` as an example
-
-java server
-
-```bash
-cd helloworld/dubbo/java-server
-sh build.sh
-
-cd ./target

+ * ExecuteLimitFilter

+ * example:
+ * "UserProvider":
+ *   registry: "hangzhouzk"
+ *   protocol : "dubbo"
+ *   interface : "com.ikurento.user.UserProvider"
+ *   ... # other configuration
+ *   execute.limit: 200 # the name of MethodServiceTpsLimiterImpl. if the value < 0, invocation will be ignored.
+ *   execute.limit.rejected.handle: "default" # the name of rejected handler
+ *   methods:
+ *    - name: "GetUser"
+ *      execute.limit: 20, # in this case, this configuration in service-level will be ignored.
+ *    - name: "UpdateUser"
+ *      execute.limit: -1, # If the rate<0, the method will be ignored
+ *    - name: "DeleteUser"
+ *      execute.limit.rejected.handle: "customHandler" # Using the custom handler to do something when the request was rejected.
+ *    - name: "AddUser"
+ * From the example, the configuration in service-level is 200, and the configuration of method GetUser is 20.
+ * it means that, the GetUser will be counted separately.
+ * The configuration of method UpdateUser is -1, so the invocation for it will not be counted.
+ * So the method DeleteUser and method AddUser will be limited by service-level configuration.
+ * Sometimes we want to do something, like log the request or return default value when the request is over limitation.
+ * Then you can implement the RejectedExecutionHandler interface and register it by invoking SetRejectedExecutionHandler.

+ * MethodServiceTpsLimiterImpl
+ * This implementation allows developer to config both method-level and service-level tps limiter.

+ *   protocol : "dubbo"
+ *   interface : "com.ikurento.user.UserProvider"
+ *   ... # other configuration
+ *   tps.limiter: "method-service" or "default" # the name of MethodServiceTpsLimiterImpl. It's the default limiter too.
+ *   tps.limit.interval: 5000 # interval, the time unit is ms
+ *   tps.limit.rate: 300 # the max value in the interval. <0 means that the service will not be limited.
+ *   methods:
+ *    - name: "GetUser"
+ *      tps.interval: 3000
+ *      tps.limit.rate: 20, # in this case, this configuration in service-level will be ignored.
+ *    - name: "UpdateUser"
+ *      tps.limit.rate: -1, # If the rate<0, the method will be ignored
+ *
+ *
+ * More examples:
+ * case1:
+ * "UserProvider":
+ *   registry: "hangzhouzk"
+ *   protocol : "dubbo"
+ *   interface : "com.ikurento.user.UserProvider"
+ *   ... # other configuration

+ *   methods:
+ *    - name: "GetUser"
+ *    - name: "UpdateUser"
+ *      tps.limit.rate: -1,
+ * in this case, the method UpdateUser will be ignored,
+ * which means that only GetUser will be limited by service-level configuration.
+ *
+ * case2:
+ * "UserProvider":
+ *   registry: "hangzhouzk"
+ *   protocol : "dubbo"
+ *   interface : "com.ikurento.user.UserProvider"
+ *   ... # other configuration

+ *      tps.limit.rate: 30,
+ * In this case, the GetUser will be limited by service-level configuration(300 times in 5000ms),
