Controller类中的HTTP路由多次调用Cordapp

Question

我看到路由/问题的多个调用不确定为什么这样的行为

    // initiate a flow using this route

    @GetMapping(value = "/issue", produces = TEXT_PLAIN_VALUE)
    private String issue() throws FlowException {
        Party traderB = proxy.networkMapSnapshot().get(2).getLegalIdentities().get(0);

        proxy.startFlowDynamic(com.template.flows.IssueMetal.class,"Gold",10,traderB).toString();

        return proxy.registeredFlows().toString();
    }

并且当我查询库时，我看到多个未使用状态，而我应该只看到一个条目。

我有4个节点

TraderA，TraderB，薄荷，公证人

此流程正在从Mint发布到TraderB。

我相信Ashutosh是正确的。您的端点似乎被多次触发，这是您在此处看到所见内容的唯一原因。
