未注入Websphere 18.0.0.3 MySQL数据源对象

Question

我的web应用程序没有获得server.xml中配置的数据源。我在C:\wlp\usr\shared\resources\mysql文件夹下添加了sql连接器jar (mysql-连接器-java-8.0.12)

server.xml

<!--    Enable    features    -->                
    <featureManager>
    <feature>cdi-1.2</feature>
    <feature>jaxrs-2.0</feature>
    <feature>jdbc-4.0</feature>
    <feature>jndi-1.0</feature>
    <feature>jpa-2.0</feature>
    <feature>localConnector-1.0</feature>
    <feature>servlet-3.1</feature>
    </featureManager>

    <!--    Declare    the    jar    files    for    MySQL    access    through    JDBC.    -->
    <library id="MySQLLib">
      <fileset dir="${shared.resource.dir}/mysql" includes="mysql-connector-java-8.0.12.jar"/>
    </library>
    <!-- Declare the runtime database -->
    <dataSource jndiName="AdminWeb/jdbc/AdminDS" transactional="false">
      <jdbcDriver libraryRef="MySQLLib"/>
      <properties databaseName="admin" password="****" portNumber="3306" serverName="localhost" user="root"/>
    </dataSource>

DAO

@Resource(name = "AdminWeb/jdbc/AdminDS",lookup="AdminWeb/jdbc/AdminDS")
DataSource dataSource;

public UserEntity getAllUsers() {
    UserEntity user = new UserEntity();
   Connection connection = null;
    try {
        System.out.println("****************1");
        connection = dataSource.getConnection();
        System.out.println("2");

调用webapp时，getconnection方法抛出

ERROR SRVE0777E:应用程序类SRVE0777E java.lang.NullPointerException引发的异常

有人能帮我一下吗？

Answer 1

dataSource/服务器配置本身看起来很好。@Resource只能注入到web组件/ejb组件中。你要注入的类符合这种描述吗？
