问题描述
我想从glassfish v3服务器中配置的JNDI中查找一些属性。我想用春天来做。这里是我的春天配置：
< beans xmlns =http://www.springframework.org/schema/beans
xmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
xmlns：aop =http://www.springframework.org/schema/aop
xmlns：jee =http://www.springframework.org/schema/jee
xmlns：jaxws =http://cxf.apache.org/jaxws
xsi：schemaLocation = http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org / schema / aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws。 xsd
http://www.springframework.org/schema/jee
http://www.springframework.org/schema/jee/spring-jee-3.0.xsd\">
< import resource =classpath：META-INF / cxf / cxf.xml/>
< import resource =classpath：META-INF / cxf / cxf-servlet.xml/>
JNDI查找。
！ - >
< jee：jndi-lookup id =properties
jndi-name =java：comp / env / jndi / ws_properties
expected-type =java.util.Properties />
< / beans>
我在sun中映射了 jndi / ws_properties -web.xml和web.xml文件。问题是这个查找总是给我null属性。但是，如果我在java代码中执行它：
try {
InitialContext context = new InitialContext（）;
properties =（Properties）context.lookup（jndi / ws_properties）;
} catch（NamingException e）{
LOGGER.error（，e）;
}
没关系。
有人可以告诉我问题在哪里吗？
方案这可能是因为您的jndi-name属性。
$ b
您不必将java：comp / env / 在名称中。
resource-ref属性默认为true，除非将其设置为false，否则它会自动将java：comp / env添加到名称。
I want to look up some properties from JNDI configured in glassfish v3 server. I want to do it using spring. Here is my spring configuration:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/jee
http://www.springframework.org/schema/jee/spring-jee-3.0.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<!--
JNDI look ups.
!-->
<jee:jndi-lookup id="properties"
jndi-name="java:comp/env/jndi/ws_properties"
expected-type="java.util.Properties"/>
</beans>
I have mapped jndi/ws_properties in sun-web.xml and web.xml files. Problem is that this lookup always gives me null properties. But if I do it in java code:
try {
InitialContext context = new InitialContext();
properties = (Properties) context.lookup("jndi/ws_properties");
} catch (NamingException e) {
LOGGER.error("", e);
}
It is ok. I see my properties keys and values.
Could somebody tell me where is the problem here?
解决方案
This is probably because of your "jndi-name" property.
You don't have to put "java:comp/env/" in the name.
The "resource-ref" property defaults to true and unless you set it to false, it will automatically add the java:comp/env to the name.
