hi, @zouchangfu
first of all thank you for your willingness to help me.
I want to write integration tests for hystrix. #2985
So I need to implement hystrix's circuit breaker.
For example, after the system reaches the maximum number of requests,
hystrix performs fuse.
The system will return to the user a ""You have been restricted, please try
again later!"" prompt.
For example in this file,
`shenyu-integrated-test/shenyu-integrated-test-http/src/test/java/org/apache/shenyu/integrated/test/http/combination/SentinelPluginTest.java`
```java
@Test
public void test() throws IOException {
String selectorAndRulesResult =
initSelectorAndRules(PluginEnum.SENTINEL.getName(), "",
buildSelectorConditionList(), buildRuleLocalDataList(null));
assertThat(selectorAndRulesResult, is("success"));
Type returnType = new TypeToken<Map<String, Object>>() {
}.getType();
Map<String, Object> result =
HttpHelper.INSTANCE.postGateway(TEST_SENTINEL_PATH, returnType);
assertNotNull(result);
assertEquals("pass", result.get("msg"));
result = HttpHelper.INSTANCE.postGateway(TEST_SENTINEL_PATH,
returnType);
assertEquals("You have been restricted, please try again later!",
result.get("message"));
}
```
SentinelPlugin implements a circuit breaker mechanism. The first request
will return pass, and then the system will be blown, and a prompt of ""You have
been restricted, please try again later!" will be returned.
I would like to ask you to give an example, how do I change the SelectorList
and rule of the hystrix plugin to achieve this circuit breaker mechanism?
