java - Weblogic 10.3 MDB 抛出 javax.sql.DataSource 异常

Question

以下是我正在使用的应用程序：

网络逻辑 10.3.3
Websphere MQ 7.0
Oracle 11g 快捷版 (DB)

以下是当前的流程：

一条消息由 Weblogic 从 Websphere MQ 队列中读取并由 MDB 处理
MDB 将消息保存到 DB
MDB 将消息写入另一个 Websphere MQ 队列

这是一个 XA 事务，因此如果上述任何操作失败，消息将返回到原始队列。

这是我在 Websphere MQ 队列上放置消息以启动进程时出现的错误：

这是我在代码中连接到数据库的方式

// Datasource declaration
@Resource(name = "database", mappedName = "datasource/oracle-11g")
private DataSource database;
...
// Save data to messages table
String sql = "insert into messages(payload) values(?)";
OracleConnection dbConn = (OracleConnection) database.getConnection();
OraclePreparedStatement insertSql = (OraclePreparedStatement)   
dbConn.prepareStatement(sql);
insertSql.setStringForClob(1, msgPayload);
insertSql.execute();

到目前为止，我已经完成了以下故障排除：

我检查了我的数据源以确认 jndi 名称确实是“datasource/oracle-11g
在数据源设置期间，我已成功通过测试配置按钮连接到数据库
我已经验证消息表确实存在于数据库中

无论如何要打开日志记录，以便我可以查看到数据库的任何特定 JDBC 连接错误？

您可能没有为 weblogic 管理控制台中定义的数据源设置目标管理服务器。如果设置正确，则不应出现此错误。

你的配置有问题。这是告诉您的消息：

Caused by: com.bea.core.repackaged.springframework.beans.factory.NoSuchBeanDefin
itionException: No unique bean of type [javax.sql.DataSource] is defined: No bea
ns of type javax.sql.DataSource

您要么没有 DataSource，要么配置不正确。

从发布的跟踪来看，MDB 似乎无法写入数据库，因为DataSource注入失败：

No unique bean of type [javax.sql.DataSource] is defined

某处发生碰撞。我认为您需要告诉我们更多信息以获得更准确的答案。

更新：我想知道是否name对@ResourceandDataSource属性使用相同（database在这种情况下）不会导致问题。

所以，而不是：

// Datasource declaration
@Resource(name = "database", mappedName = "datasource/oracle-11g")
private DataSource database;

你可以试试这个（假设datasource/oracle-11g是全局 JNDI 名称）：

// Datasource declaration
@Resource(mappedName="datasource/oracle-11g") 
private DataSource database;
