Spring Boot JNDI应用程序设置

标签： java spring spring-boot javabeans jndi

我正在尝试创建一个使用JNDI连接到数据库的测试spring引导项目。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);
    }
}

当我运行时，我收到此错误：

我做错了什么？

更新1： 这是我的pom.xml

Spring Boot旨在简化所有事情。

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

只保留一个没有前缀的application.properties中数据源的JNDI名称。希望您在Tomcat上成功配置它。

spring.datasource.jndi-name=jdbc/test

然后从AppConfig中删除datasource（）方法。 只需注入（自动装配）数据源并使用它。
