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：

1. Weblogic 10.3.3
2. Websphere MQ 7.0
3. Oracle 11g 快捷版 (DB)

这是当前的流程：

1. 消息由 Weblogic 从 Websphere MQ 队列中读取并由 MDB 处理
2. MDB 将消息保存到 DB
3. 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，我已完成以下故障排除工作：

1. 我检查了我的数据源，确认 jndi 名称确实是“datasource/oracle-11g”
2. 在数据源设置过程中，我已成功通过测试配置按钮连接到数据库
3. 我已验证消息表确实存在于数据库中

是否可以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？

Answer 1

您的配置有问题。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

您要么没有数据源，要么没有正确配置。

Answer 2

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：我想知道是否对@Resource 和DataSource 属性（在本例中为database）使用相同的name 不会导致问题。

所以，而不是：

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

你能试试这个吗（假设datasource/oracle-11g 是全局 JNDI 名称）：

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

另见：

Answer 3

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，则不会出现此错误。
