[英]Embedded tomcat jndi definition
I'm using spring with embedded tomcat. 我正在使用带有嵌入式tomcat的spring。 I don't want application.properties
to be used anymore, since it should be published to a webserver running tomcat and there I'm now using a JNDI dataSource from a context.xml which works very well. 我不希望再使用application.properties
,因为应该将它发布到运行tomcat的Web服务器上,现在我正在使用来自context.xml的JNDI数据源,效果很好。 Now I want to define that JNDI resource for embedded tomcat, but it does not work. 现在,我想为嵌入式tomcat定义该JNDI资源,但是它不起作用。
What I've tried: 我尝试过的
context.xml context.xml
<?xml version='1.0' encoding='utf-8'?>
<Context>
<Resource name="jdbc/db" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="root" password="root" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/db"/>
</Context>
Configuration.java 配置文件
@Bean
public DataSource dataSource() {
final JndiDataSourceLookup lookup = new JndiDataSourceLookup();
lookup.setResourceRef(true);
return lookup.getDataSource("jdbc/db");
}
@Bean
public TomcatEmbeddedServletContainerFactory tomcatFactory() {
return new TomcatEmbeddedServletContainerFactory() {
@Override
protected TomcatEmbeddedServletContainer getTomcatEmbeddedServletContainer(Tomcat tomcat) {
tomcat.enableNaming();
return super.getTomcatEmbeddedServletContainer(tomcat);
}
};
}
and I'm getting: 我得到:
Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]:
Factory method 'dataSource' threw exception; nested exception is org.springframework.jdbc.datasource.lookup.DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'jdbc/db';
nested exception is javax.naming.NameNotFoundException: Name [jdbc/db] is not bound in this Context. Unable to find [jdbc].
Please help me, thanks :) 请帮助我,谢谢:)
Try with 试试看
lookup.getDataSource("java:/comp/env/jdbc/db");
without java:comp, jndi can not be found."comp" is short for component and is bound to root context. 如果没有java:comp,就找不到jndi。“ comp”是组件的缩写,绑定到根上下文。
