java - 如何使用 Spring Boot 和 WildFly 11.0 配置 JNDI 数据源

Question

我想使用 Spring Boot 和 WildFly 11.0 配置 JNDI 数据源。我目前正在使用 Postgres DB，并且在 application.properties 下有数据源配置。

我知道可以使用 application.properties 中的以下内容创建 jndi。我所困扰的是如何将其与 JBoss WildFly 联系起来？

a.我需要在 WildFly 中的standalone.xml 下添加/更改什么b. Spring Boot 主应用程序类 ProjectPocApiApplication 下所需的任何更改

谢谢

ProjectPocApiApplication.java

@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WildFly主目录下存在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>

我想你可以使用下面的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;
}

(没有真正测试过，只是把它扔掉)
