[英]simple_one_for_one child can not start
我写了一些代码来测试simple_one_for_one主管,但是它不能工作,代码是:
-module(test_simple_one_for_one).
-behaviour(supervisor).
%% API
-export([start_link/0, start_fun_test/0]).
%% Supervisor callbacks
-export([init/1]).
-define(SERVER, ?MODULE).
%%--------------------------------------------------------------------
start_link() ->
{ok, Pid} = supervisor:start_link({local, ?SERVER}, ?MODULE, []).
start_fun_test() ->
supervisor:start_child(test_simple_one_for_one, []).
init([]) ->
RestartStrategy = simple_one_for_one,
MaxRestarts = 1000,
MaxSecondsBetweenRestarts = 3600,
SupFlags = {RestartStrategy, MaxRestarts, MaxSecondsBetweenRestarts},
Restart = permanent,
Shutdown = 2000,
Type = worker,
AChild = {fun_test_sup, {fun_test, run, []},
Restart, Shutdown, Type, [fun_test]},
io:format("start supervisor------ ~n"),
{ok, {SupFlags, [AChild]}}.
当我跑步
test_simple_one_for_one:start_link().
和
test_simple_one_for_one:start_fun_test().
在erl shell中,它给我错误:
test_simple_one_for_one:start_fun_test()。 **异常退出:函数gen_server:call / 3中的{noproc,{gen_server,call,[test_simple_one_for_one,{start_child,[]},infinity]}}}(gen_server.erl,第188行)
如果这是您为测试编写的所有代码,请当心,当您注册一个监督孩子时,您会得到一个{M,F,A}元组,该元组代表您启动孩子时调用的函数。
就您而言,我认为它不能简单地找到fun_test:run / 1函数。
