Weblogic 10.3 MDB抛出javax.sql.DataSource异常

时间：2010-07-01 00:45:45

标签： java java-ee ejb-3.0 weblogic-10.x message-driven-bean

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 Express Edition（DB）

    4. 这是当前的流程：

    1. Weblogic从Websphere MQ队列读取消息并由MDB处理
    2. MDB将消息保存到数据库
    3. MDB将消息写入另一个Websphere MQ队列

      4. 这是一个XA事务，因此如果上述任何操作失败，该消息将返回到原始队列。

      当我在Websphere MQ队列上放置一条消息以启动进程时出现错误：

      以下是我在代码

      中连接数据库的方法 
      // 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，我已完成以下问题排查：

      1. 我检查了我的数据源以确认jndi名称确实是“datasource / oracle-11g
      2. 我在数据源设置期间通过“测试配置”按钮成功连接到数据库
      3. 我已验证消息表确实存在于db
        4. 中

        无论如何都要打开日志记录，以便我可以看到数据库中任何特定的JDBC连接错误？

3 个答案:

答案 0 :(得分：1)

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。

答案 1 :(得分：0)

您的配置有问题。这是告诉你的信息：

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。

答案 2 :(得分：0)

从发布的跟踪中，似乎MDB无法写入数据库，因为DataSource无法注入：

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

某处发生了碰撞。我想你需要告诉我们更多更准确的答案。

更新：我想知道name和@Resource属性（本例中为DataSource）使用相同的database是不是导致问题。

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;
