枚举常量

枚举常量	说明
CLOSED	In CLOSED state, all requests are permitted.
HALF_OPEN	In HALF_OPEN state, the circuit breaker will allow a "probe" invocation.
OPEN	In OPEN state, all requests will be rejected until the next recovery time point.

方法概要

枚举常量详细资料

OPEN

public static final CircuitBreaker.State OPEN

In OPEN state, all requests will be rejected until the next recovery time point.

HALF_OPEN

public static final CircuitBreaker.State HALF_OPEN

In HALF_OPEN state, the circuit breaker will allow a "probe" invocation. If the invocation is abnormal according to the strategy (e.g. it's slow), the circuit breaker will re-transform to the OPEN state and wait for the next recovery time point; otherwise the resource will be regarded as "recovered" and the circuit breaker will cease cutting off requests and transform to CLOSED state.

CLOSED

public static final CircuitBreaker.State CLOSED

In CLOSED state, all requests are permitted. When current metric value exceeds the threshold, the circuit breaker will transform to OPEN state.

方法详细资料

values

public static CircuitBreaker.State[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

返回:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static CircuitBreaker.State valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - 如果参数为空值
