Question

我正在尝试使用for-each插入MySQL，因为我的输入JSON可以有多个值。

employee id，projectname和startdate是强制性的，每次都会将它们插入数据库。

虽然可能有其他字段，但只有在重新启动Mule后才会将它们插入到数据库中。此代码在重新启动Mule（插入所有值）后突然再次停止工作（仅插入强制值），然后在重新启动后再次工作。

我启用了日志记录，我可以看到JSON输入格式正确。

以下是我的Mule配置xml文件：

Here is my Json sample.

{
    "newprojects": {
        "projects": [
            {
                "employeeid": "2",
                "projectname": "1112",
                "notes": "projectanotes",
                "StartDate": "2015-01-01",
                "EndDate": "2015-01-01",
                "ClientRate": "20",
                "EmployeeRate": "20"
            },
            {
                "employeeid": "2",
                "projectname": "1121",
                "notes": "projectanotes",
                "StartDate": "2015-01-01",
                "EndDate": "2015-01-01",
                "ClientRate": "20",
                "EmployeeRate": "20"
            }
        ]
    }
}

有没有人遇到过同样的问题，或者看到有什么不妥之处？

Mule ESB数据库插入仅在Mule重启后才能工作
