wildfly-swarm jpa/dadatasources yaml.xml

问题

I have a question.I am integrating EJB, JAX-RS, CDI, JPA, and data sources. When I integrate these into wildfly-swarm, there are some problems that can not work properly.

 yaml.xml:

        datasources:

          jdbc-drivers:
                    com.mysql:
                    driver-class-name: com.mysql.jdbc.Driver
                    xa-datasource-class-name: com.mysql.jdbc.jdbc2.optional.MysqlXADataSource
                    driver-module-name: com.mysql

          data-sources:
                    PicketlinkDS:
                    driver-name: com.mysql
                    connection-url: jdbc:mysql://localhost:3306/testjpa
                    user-name: root
                    password: javacom2
                    jta : true
                    use-java-context: true 
                    min-pool-size : 8
                    max-pool-size : 20
                    pool-prefill  : true
                    connection-checker-class-name : org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker
                    background-validation : true
                    exception-sorter-class-name : org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter
                    connection-properties : CharacterEncoding/ UTF-8 UseUnicode/true

swarm.start();
swarm.deploy(deployment);

exception: "WFLYCTL0412: Required services that are not installed:" =>"jboss.naming.context.java.jboss.datasources.PicketlinkDS"],

idea ,Run on how to deal with this exception? Very anxious！！！！！！！！

回答1:

First off I'd suggest removing the custom main() as there's nothing specific you're doing there that can't be achieved with Maven war packaging.

Secondly, I think your yaml is missing the swarm: as the first level, and you can also remove the JDBC Driver creation and let WF Swarm do that for you. For that I switched the driver-name to mysql, which will work so long as the JDBC driver dependency for MySQL is part of the project.

swarm:
  datasources:
    data-sources:
      PicketlinkDS:
        driver-name: mysql
        connection-url: jdbc:mysql://localhost:3306/testjpa
        user-name: root
        password: javacom2
        jta: true
        use-java-context: true 
        min-pool-size: 8
        max-pool-size: 20
        pool-prefill: true
        connection-checker-class-name: org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLValidConnectionChecker
        background-validation: true
        exception-sorter-class-name: org.jboss.jca.adapters.jdbc.extensions.mysql.MySQLExceptionSorter
        connection-properties: CharacterEncoding/ UTF-8 UseUnicode/true
