Question

我正在尝试使用Wso2Sp连接到Postgres Db。

我尝试对SP_Home / conf / worker /中的Deployment.yaml文件进行更改。

如documentation中所述，这是我添加到wso2.datasources部分的部分。

# Postgres
    -  name: WSO2_TEST_DB
       description: The datasource used for test database
       jndiConfig: 
         name: jdbc/WSO2_TEST_DB
       definition:
         type: RDBMS
         configuration:
           jdbcUrl: jdbc:postgresql://<host>:<port>/<db>
           username: <user>
           password: <password>
           driverClassName: org.postgresql.Driver
           maxPoolSize: 10
           idleTimeout: 60000
           connectionTestQuery: SELECT 1
           validationTimeout: 30000
           isAutoCommit: false

当我重新启动工作容器并检查日志时，这就是我得到的。

我在这里想念什么？

您必须将OSGi兼容的postgresql连接器添加到{SP_HOME} / lib文件夹。
