Spring 3 JNDI在glassfish3中查找 [英] Spring 3 JNDI look up in glassfish3

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

 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.
