java - Spring Boot JNDI应用程序设置

Question

我正在尝试创建一个使用 JNDI 连接到数据库的测试 Spring Boot 项目。这是我的application.properties:

spring.datasource.name=jdbc/test
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.jndi-name=java:jdbc/test
spring.datasource.url=...
spring.datasource.username=...
spring.datasource.password=...
spring.datasource.type=javax.sql.DataSource
spring.datasource.separator=;

这是我的配置文件:

@Configuration
@EnableConfigurationProperties
public class AppConfig {
    @Bean
    public TomcatEmbeddedServletContainerFactory tomcatFactory() {
        return new TomcatEmbeddedServletContainerFactory() {
            @Override
            protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
                tomcat.enableNaming();
                return super.getTomcatEmbeddedServletContainer(tomcat);
            }
        };
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        JndiDataSourceLookup dataSourceLookup = new JndiDataSourceLookup();
        DataSource dataSource = dataSourceLookup.getDataSource("java:jdbc/test");
        return dataSource;
    }
}

这是我的 Application.java 文件:

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

当我运行此命令但出现此错误时:

我做错了什么？

更新 1:这是我的 pom.xml

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <addResources>true</addResources>
                </configuration>
            </plugin>
        </plugins>
    </build>

Spring Boot 旨在简化所有这些事情。

您的属性中应该有datasource url、username、password或其jndi-name，而不是两个选项一起。

在 application.properties 中只保留一个与数据源相关的 JNDI 名称，不带前缀。希望您在 Tomcat 上配置成功。

spring.datasource.jndi-name=jdbc/test

然后从 AppConfig 中删除 datasource() 方法。只需注入(inject)( Autowiring )数据源并使用它。
