[英]Mule JDBC Datasource connection
I have mule 3.5 db configuration as follows 我有如下的m子3.5 db配置
<spring:beans>
<spring:bean id="pds" name="pds" class="com.mchange.v2.c3p0.ComboPooledDataSource" scope="singleton">
<spring:property name="password" value="pwd"/>
<spring:property name="jdbcUrl" value="jdbc:postgresql://localhost:5432/postgres"/>
<spring:property name="user" value="user"/>
<spring:property name="driverClass" value="org.postgresql.Driver"/>
</spring:bean>
</spring:beans>
<db:generic-config name="Postgres_Datasource_Configuration" transactionIsolation="READ_COMMITTED" doc:name="Generic Database Configuration" dataSource-ref="pds"/>
my flow looks like 我的流程看起来像
<flow name="JDBC-PostgresConfigurationWithDatasource" doc:name="JDBC-OracleConfigurationWithDatasource">
<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP" path="postgresInboundWithDS"/>
<logger level="INFO" doc:name="Logger"/>
<db:select config-ref="Postgres_Datasource_Configuration" doc:name="Database">
<db:parameterized-query><![CDATA[SELECT * FROM employee]]></db:parameterized-query>
</db:select>
<mulexml:object-to-xml-transformer doc:name="Object to XML"/>
<logger level="INFO" doc:name="Logger" message="#[payload]"/>
<logger level="INFO" doc:name="Logger"/>
</flow>
I am always getting the error saying 我总是得到错误的说
The attributes of Element db:generic-config{dataSource-ref=pds, name=Generic Database Configuration, name=Postgres_Datasource_Configuration, transactionIsolation=READ_COMMITTED} do not match the exclusive groups [driver, url, connectionTimeout, transactionIsolation, useXaTransactions] [dataSource-ref] 元素db:generic-config {dataSource-ref = pds,name = Generic Database Configuration,name = Postgres_Datasource_Configuration,transactionIsolation = READ_COMMITTED}的属性与排他组不匹配[驱动程序,URL,connectionTimeout,transactionIsolation,useXaTransactions] [dataSource-参考]
What I didn't get is I mentioned dataSource-ref, but still it is showing error as mutually exclusive. 我没有得到的是我提到的dataSource-ref,但仍然显示错误是互斥的。
I observed the same behavior with oracle connector also. 我也观察到与oracle连接器相同的行为。
But I am able to connect to db when I am not using spring bean datasource. 但是当我不使用spring bean数据源时,我能够连接到db。
One more weird thing is, when I was working with mule 3.4 it worked fine. 另一件事是,当我使用I子3.4时,它工作正常。 Now, in 3.5 it is showing errors. 现在,在3.5中显示错误。
Am I missing anything? 我有什么想念的吗?
According to the error message, if you specify dataSource-ref
, then you can't specify transactionIsolation
. 根据错误消息,如果指定dataSource-ref
,则不能指定transactionIsolation
。
So remove the transactionIsolation
from db:generic-config
. 因此,从db:generic-config
删除transactionIsolation
。
