Question

我的Web应用程序中有一个Spring 4.1.4框架，我想要外部数据库配置，然后将db信息放入META-INF / context.xml

我经常使用XML Spring配置，如果我尝试按如下方式检索我的连接：

的applicationContext-dataSource.xml

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/informagiovani" />
    <property name="proxyInterface" value="javax.sql.DataSource" />
</bean>

的beans.xml

<import resource = "spring/applicationContext-dataSource.xml" />

Java DAO

public Connection getConnection() {
    Connection conn = null;
    try {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("resources/beans.xml"); 
        DataSource dataSource = (DataSource) context.getBean("dataSource");
        conn = dataSource.getConnection();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return conn;
}

一切正常..如果我尝试使用如下注释：

的AppConfig

@Configuration
public class DataSourceConfiguration {
@Bean
public DataSource dataSource() {
    final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
    dsLookup.setResourceRef(true);
    DataSource dataSource = dsLookup.getDataSource("jdbc/informagiovani");
    return dataSource;
}
}

Java DAO

public Connection getConnection() {
    AnnotationConfigApplicationContext ctx = new AnnotationConfigApplicationContext(DataSourceConfiguration.class);
    Connection conn = null;
    try {
        DataSource dataSource = ctx.getBean(DataSource.class);
        conn = dataSource.getConnection();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return conn;
}

我得到以下错误：

显然jar是在Spring-jdbc 4.1.4中。你能救我吗？

我的pom.xml如下：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
    <version>2.0.2.RELEASE</version>

即使我添加spring-boot-starter依赖项，错误也是一样的。谢谢
