启动日志“未找到交易管理器"； [英] Startup-Log "No Transaction manager found"

问题描述

当我开始跳船时，日志中将显示以下行:

When I start jetty, following line appears in Log:

:INFO:oejpw.PlusConfiguration:No Transaction manager found
- if your webapp requires one, please configure one.

• 这是什么意思?
• 我怎么知道我的Web应用程序需要交易管理器?
• 哪些功能可为此类交易管理器提供服务?如果我没有该功能，我会缺少什么?

推荐答案

通常，如果您需要一个，就知道您需要一个.

Typically if you need one, you know you need one.

此处所指的是事务管理器，例如Atomikos或JOTM.用于利用JTA api进行分布式事务:

Transaction managers like Atomikos or JOTM are what are being referred to here. Used for distributed transactions leveraging the JTA api:

因此，在jetty的情况下，这是一条提示性消​​息，当使用jetty-plus配置时，启动时没有通过jndi绑定此类api. jetty-plus本身是一个模块，用于集成到严格的servlet-api之外的资源，但对人们仍然经常有用.

So in jetty's case it is an informational message that no such api has been bound via jndi on startup when using the jetty-plus configuration. jetty-plus in of itself is a module for integrating to resources that are outside of the strict servlet-api sense but are still often useful for people.
