使用JNDI

Question

我有一个JndiDatasourceCreator类，并且在应用程序上下文中有一个bean

<bean id="jndi" class="se.test.util.JndiDatasourceCreator" lazy-init="false" />

工作正常。但是，当我将其移入Java配置时，它无法正常工作。

这样的Java配置bean

@Bean
  @Lazy(value = false)
  public JndiDatasourceCreator jndi(){
    return new JndiDatasourceCreator();
  }

我现在遇到这样的错误

Caused by: org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'jdbc/sharedTender'; nested exception is javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

我的JNDI创建者类在这里：

public class JndiDatasourceCreator {

    public JndiDatasourceCreator(){
        try {
            DriverManagerDataSource dataSource=null;
            final SimpleNamingContextBuilder builder = new SimpleNamingContextBuilder();
            dataSource = new DriverManagerDataSource();
            dataSource.setDriverClassName("org.mariadb.jdbc.Driver");
            dataSource.setUrl("jdbc:mysql://localhost:3306/rshared?autoReconnect=true");
            dataSource.setUsername("root");
            dataSource.setPassword("root");
            builder.bind("jdbc/sharedTender", dataSource);
            builder.activate();
        } catch (NamingException ex) {
            ex.printStackTrace();
        }
    }
}

感谢您的帮助！
