如何使用Spring Boot配置JNDI数据源

Question

我想用Spring Boot配置JNDI数据源

我知道可以在application.properties.中使用以下内容创建jndi。我在纠结的是如何将其与JBoss WildFly联系起来？

a.我需要在WildFly的standalone.xml下添加/更改什么和b. Spring Boot主应用程序类ProjectPocApiApplication下需要的任何更改

谢谢

@SpringBootApplication
public class ProjectPocApiApplication  extends SpringBootServletInitializer{

public static void main(String[] args) {

    SpringApplication.run(ProjectPocApiApplication.class, args);
}

@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
    return builder.sources(ProjectPocApiApplication.class);

}}

我假设您需要在独立xml的数据源子系统中进行以下配置。（确保在WildFly home目录下存在org.postgresql模块结构）

<subsystem xmlns="urn:jboss:domain:datasources:2.0">
    <datasources>
        <datasource jndi-name="java:jboss/datasources/PostgreSQLDataSource" pool-name="PostgreSQLDataSourcePool" enabled="true" use-java-context="true">
            <connection-url>jdbc:postgresql://localhost/test</connection-url>
            <driver>postgresql</driver>
        </datasource>
        <drivers>
            <driver name="postgresql" module="org.postgresql">
                <datasource-class>org.postgresql.Driver</datasource-class>
            </driver>
        </drivers>
    </datasources>
</subsystem>

我想您可以使用以下方法在主类中配置数据源

@Bean
public DataSource dataSource() 
{
  JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
  DataSource dataSource = dataSourceLookup.getDataSource("java:jboss/datasources/PostgreSQLDataSource");
  return dataSource;
}

（没有真正测试，只是扔掉它）
