Spring Boot JNDI资源引用 [英] Spring Boot JNDI resource-ref

问题描述

我需要在Spring Boot应用程序中声明一个资源引用，该资源将作为war文件部署。为了访问数据库，这是必需的。在传统的Web应用程序中，这已添加到web.xml中。如何以Spring Boot方式实现这一目标？

I need to declare a resource-ref in a Spring Boot application that will be deployed as war file. This is needed in order to access the database. In traditional webapps, this is added to the web.xml. How can I achieve this in a Spring Boot way?

谢谢，

推荐答案

前一阵子我们解决了这个问题，所以我想将其发布在这里。

We got that resolved a while back, so I thought, I'd post this here.

src / main / webapp / WEB-INF / web.xml

src/main/webapp/WEB-INF/web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">
  <resource-ref>
    <res-ref-name>jdbc/DefaultDB</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
  </resource-ref>
</web-app>

---

src / main / resources / application.yml

---

src/main/resources/application.yml

spring:
  datasource:
    jndi-name: jdbc/DefaultDB

---

src / main / java // DataSourceConfiguration.java

---

src/main/java//DataSourceConfiguration.java

@Configuration
public class DataSourceConfiguration {

    @Bean
    @ConditionalOnMissingBean // optional
    public DataSource jndiDataSource(DataSourceProperties properties) {
        InitialContext context = new InitialContext();
        return (DataSource) context.lookup("unmanageddatasource:" + properties.getJndiName());
    }
}
