我是Spring Boot的新手。我想定义spring boot中的context.xml中存在的资源标记。这样我就可以为jdbctemplate定义我的数据源。
这就是我在做的事情：
@SpringBootApplication
@EnableAutoConfiguration(exclude = {ErrorMvcAutoConfiguration.class})
public class Application extends SpringBootServletInitializer{
private static final Logger LOGGER = Logger.getLogger(Application.class);
public static void main(String[] args) {
LOGGER.info("Spring Boot Application Started");
SpringApplication.run(Application.class, args);
LOGGER.info("Spring Boot Application Ended");
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
@Bean
public EmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(
Tomcat tomcat) {
tomcat.enableNaming();
return super.getTomcatEmbeddedServletContainer(tomcat);
}
@Override
protected void postProcessContext(Context context) {
ContextResource resource = new ContextResource();
resource.setName("jdbc/mydb");
resource.setType(DataSource.class.getName());
resource.setProperty("driverClassName", "oracle.jdbc.OracleDriver");
resource.setProperty("url", "jdbc:oracle:thin:@localhost:1521:XE");
resource.setAuth("Container");
resource.setProperty("username","uname");
resource.setProperty("password","pword");
resource.setProperty("validationQuery","select 1 from dual");
resource.setProperty("initSQL","select 1 from dual");
context.getNamingResources().addResource(resource);
}
};
}
@Bean(destroyMethod="")
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
bean.setJndiName("java:comp/env/jdbc/mydb");
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet();
return (DataSource)bean.getObject();
}
}
但我得到了这个例外：

我在这里缺少什么.. ??
即使我试过
@Resource(name="jdbc/mydb", type=javax.sql.DataSource.class, lookup="jdbc/mydb")
但它不起作用。
我也试过
@Bean(destroyMethod="")
public DataSource dataSource() {
final JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
dsLookup.setResourceRef(true);
DataSource dataSource = dsLookup.getDataSource("jdbc/mydb");
return dataSource;
}
