标签： maven mule msbi

I have maven based interface, I need to connect MSBI database and fetch the data into mule.

I have added the required jar sqljdbc42.jar to build path.

PFB is the MSBI connection configuration:

<poll doc:name="Poll">
                <schedulers:cron-scheduler expression="${msbi.poll.schedule.cdo}"/>
                <db:select config-ref="MSBI_Database_Configuration" streaming="true" fetchSize="1000" doc:name="MSBI Select Contact CDO data">
                    <db:parameterized-query><![CDATA[SELECT [Cstmr_Acct_Id] AS SAP_Account_ID1
      ,[Accnt_Nm] AS CRM_Account_Name1
      ,[Accnt_Type] AS APL_Account_Attributes___Account_Type1
      ,[Cstmr_Sgmnt] AS CRM_Customer_Segment1
      ,[Trnprttn_role] AS CRM_Transportation_Role1
      ,CASE WHEN [Accnt_Stts]='A' THEN 'Active' WHEN [Accnt_Stts]='I' THEN 'Inactive' ELSE NULL END AS CRM_Account_Status1
      ,[Rgn] AS Region1
      ,[Rgn_desc] AS Region_Text1
      ,[Clster] AS Cluster1
      ,[Clster_desc] AS Cluster_Text1
      ,[Dstrct] AS District1
      ,[Dstrct_desc] AS District_Text1
      ,[Cntry] AS Country1
      ,[Cntry_desc] AS Country_Text1
      ,[Brnch] AS Branch1
      ,[Brnch_desc] AS Branch_Text1
      ,[Trrtry] AS Territory1
      ,[Trrtry_desc] AS Territory_Desc1
      ,[New_BT_Cd] AS BT_Code1
      ,[Lgcy_BT_Cd] AS Legacy_BTCode1
      ,[Last_Update_Dt] AS LAST_UPDATE_Date1
  FROM [dbo].[vw_elqa_CRM_Accnt_Sales_Hierarchy]
  WHERE
(
  CAST(Last_Update_Dt AS date) >= CAST(GETDATE() AS date) OR 
  CAST(Last_Update_Dt AS date) >= CAST(#[server.systemProperties['mule.env']=='dev'?server.systemProperties['msbi.debug.csr.query.filterDate']:'2100-01-01'] AS date)
) AND Cstmr_Acct_Id IS NOT NULL]]></db:parameterized-query>
                </db:select>
            </poll>

When i run the interface it is deployed successfully but while triggering the MSBI throwing below error

2 个答案:

答案 0 :(得分：2)

似乎在运行时找不到sqljdbc4.jar。

如果您使用的是Maven build（pom.xml）

将依赖项添加到pom.xml 

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
</dependency>

注意：仅供参考 -

如果您在pom.xml中使用的Maven仓库中没有任何jar，您需要自己将其添加到本地存储库/公司存储库。

要添加到本地存储库，

1.请检查您是否拥有正确版本的驱动程序jar。

2.执行以下步骤将其添加到本地Maven存储库

mvn install:install-file -Dfile=<jar_name>.jar -DgroupId=<group_id_of_jar> -DartifactId=<artifact_id_of_jar> -Dversion=<version_of_jar> -Dpackaging=jar

我正在使用Mulesoft，并使用上面的答案和@ Mahesh_Loya的评论，我能够让这个工作。

  1. 在关闭</dependencies>标记之前添加对pom.xml的依赖：

    <dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
</dependency>

  2. 在关闭</repositories>代码

    之前，将Clojars repo添加到pom.xml 
    <repository>
    <id>Clojars</id>
    <name>Clojars</name>
    <url>http://clojars.org/repo/</url>
    <layout>default</layout>
</repository>

    3. 保存pom.xml并重新运行Maven，一切都应该正常工作。快乐时光。
