There are a couple of things to fix in the configuration:

在配置中有一些事情需要修正:

Dependencies:

依赖关系:

There is a space ' ' character between <type> and jar. (Not sure if this causes any problem).
在和jar之间有一个空格'的字符。(不确定这是否会引起任何问题)。

Log4j2.xml configuration:

Log4j2。xml配置:

There are three Async appenders without a name. They MUST have names.
有三个异步appenders没有名称。他们必须有名字。
There are two root appenders. There can be only ONE root appender in a configuration, so you need to remove one of them.
有两个根appenders。在配置中只能有一个根appender，所以您需要删除其中一个。
Several Loggers do not have a level defined. If your intention is for the log level filtering to be done by the appenders, I recommend that you ensure that ALL events are passed to the appenders: I recommend you specify level TRACE on these loggers.
一些日志记录器没有定义级别。如果您的意图是为appenders所做的日志级别过滤，我建议您确保将所有事件传递给appenders:我建议您在这些日志记录器上指定级别跟踪。
The <Loggers> element does not have a closing </Loggers> tag. This may be the biggest problem.
< logger >元素没有关闭标签。这可能是最大的问题。

Are you receiving any related error? for example if it's the error: "ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogge" try this link to solve your logging issues.

你是否有任何相关的错误?例如，如果是错误:“error StatusLogger无法找到日志实现，使用SimpleLogge”尝试这个链接来解决您的日志问题。
