mysql 使用 mule esb 插入数据库

Question

你好，我正在尝试将来自 https://gist.githubusercontent.com/Rajeun/9afed4a50d2158651d6b/raw/88c7c596f3cfda48b17b76a1e12c70adf355e94d/test.json 的流插入到我的数据库中，为此我使用了 http 请求连接器，Json 对象，数据库连接器，最后是一个带有消息没问题。您可以在下面找到配置 xml:

## <mule xmlns:db="http://www.mulesoft.org/schema/mule/db" xmlns:json="http://www.mulesoft.org/schema/mule/json" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

        </response>
        <response>
            <db:insert config-ref="MySQL_Configuration" doc:name="Database">
                <db:parameterized-query><![CDATA[INSERT INTO push(token, tel, email) VALUES (2,3,#[payload['email']])]]></db:parameterized-query>
            </db:insert>
        </response>
        </flow>
    </mule> ##

应用已部署，然后出现错误循环。

我是 mule studio 的新手，我正在使用 Mule Studio CE，实际上我不知道我的例子有什么问题，请任何一步一步的帮助（比如我错过了什么组件或类似的东西） , 提前谢谢你

Answer 1

HTTPS 的端口是 443 而不是 80。 host 属性也只是主机，不应在此处放置任何协议。

所以替换这个：

host="https://gist.githubusercontent.com" port="80"

这样：

host="gist.githubusercontent.com" port="443" protocol="HTTPS"

参考material：http://www.mulesoft.org/documentation/display/current/HTTP+Request+Connector
