注册OAuth应用程序时出现WSO2 EMM错误：emm

Question

我能够使用H2数据库成功设置WSO2EMM服务器。现在尝试将数据库设置为postgresl。

登录EMM服务器https://localhost/emm时，我收到了以下异常。

请帮我解决这个错误。将WSO2AM_DB移动到postgres时出现错误。如果您需要任何其他细节，请告诉我。

这个问题可以通过配置＆＃34; defaultAutoCommit = true＆＃34;来解决。 master-datasource.xml中数据库配置中的属性。

示例数据库配置。

<configuration>
            <url>jdbc:postgresql://localhost:5432/WSO2AM_DB</url>
            <username>postgres</username>
            <password>postgres</password>
            <driverClassName>org.postgresql.Driver</driverClassName>
            <maxActive>50</maxActive>
            <maxWait>60000</maxWait>
            <testOnBorrow>true</testOnBorrow>
            <validationQuery>SELECT 1</validationQuery>
            <validationInterval>30000</validationInterval>
            <defaultAutoCommit>true</defaultAutoCommit>
</configuration>
