本文介绍了找不到TomEE部署失败的数据源的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想将War文件部署到TomEE，但是失败:

I want to deploy a war file to TomEE but fails with:

原因:

javax.naming.NameNotFoundException:
      Name openejb/Resource/application_name/mysql_ds" not found.

如果我重新启动服务器，则部署进行得很好，但只有一次，那么会遇到相同的错误.

If I restart the server, the deploy goes fine but only once, then the same error encounters.

我已经在WEB-INF/resources.xml文件中定义了数据源

I have defined datasource in WEB-INF/resources.xml file

<tomee>
    <Resource id="mysql_ds" type="javax.sql.DataSource">
        JdbcDriver  = com.mysql.jdbc.Driver
        JdbcUrl     = jdbc:mysql://IP:3306/db?serverTimezone=UTC&amp;autoReconnect=true
        UserName    = user
        Password    = password
        JtaManaged  = true
    </Resource>
</tomee>

我还应该提到另一个克隆的应用程序(开发模式)具有相同的配置，并且工作正常.

Also i should mention that there is another cloned application(dev mode) with same configuration and it works fine.

推荐答案

您可以使用WEB-INF/resources.xml定义一个或多个数据源，也可以使用<tomee-home>/conf文件夹中的tomee.xml文件，如对应部分:

You can either you use WEB-INF/resources.xml to define one or more datasources or the tomee.xml file inside the <tomee-home>/conf folder, as noted in the corresponding section of the TomEE project documentation:

但是，resources.xml的语法与容器范围的定义稍有不同.对于与您的网络应用程序捆绑在一起的resources.xml，其格式应如下所示:

However, the syntax for resources.xmlis slightly different from the container-wide definition. For a resources.xml bundled with your web-application it should be formulated as follows:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <Resource id="mysql_ds" type="javax.sql.DataSource">
        JdbcDriver  = com.mysql.jdbc.Driver
        JdbcUrl     = jdbc:mysql://IP:3306/db?serverTimezone=UTC&amp;autoReconnect=true
        UserName    = user
        Password    = password
        JtaManaged  = true
    </Resource>
</resources>

请注意，标签<resources>与问题中给出的<tomee>不同.这应该适用于默认的TomEE环境.另请参阅:rmannibucau发表的评论.

Note well, that the tag <resources> is different from <tomee> given in your question. This should work for a default TomEE environment. See also: comment by rmannibucau.
