PostgreSQL上的WSO2 API Manager在用戶登錄到商店時引發異常

Question

我已將WSO2 API Manager v1.4.0配置為使用PostgreSQL。

注冊后，用戶將無法登錄商店，並且控制台中會引發異常。 我也嘗試使用默認的管理員帳戶登錄。

將MySQL用作DBMS或登錄發布者Web UI時，不會發生此錯誤。

如何解決此錯誤？

Answer 1

此問題已在更高版本的API Manager中修復，您必須在其中添加，

<defaultAutoCommit>true</defaultAutoCommit> 

屬性設置為數據源配置。

另外，刪除元素，

<validationQuery>SELECT 1</validationQuery> 

從配置。

這在https://docs.wso2.com/display/IS510/Setting+up+PostgreSQL中提到

示例如下。

<datasource>
            <name>WSO2AM_DB</name>
            <description>The datasource used for API Manager database</description>
            <jndiConfig>
                <name>jdbc/WSO2AM_DB</name>
            </jndiConfig>
            <definition type="RDBMS">
                <configuration>
                    <url>jdbc:postgresql://localhost:5432/amdb</url>
                    <username>sdpuser</username>
                    <password>sdpuser</password>
                    <defaultAutoCommit>true</defaultAutoCommit>
