在Spring/Tomcat中，jndi查找指的是哪个配置文件?: [英] In Spring/Tomcat, which configuration file do jndi lookups refer to?:

问题描述

我无法让Spring/Tomcat应用程序解析一个变量，该变量在应用程序上下文中显示为JndiFactoryObjectName bean的属性.这是相关的bean条目:

I'm having trouble getting a Spring/Tomcat app to resolve a variable which appears as a property of a JndiFactoryObjectName bean in the application context. Here's the relevant bean entry:

当我尝试在服务器上运行它时，出现此错误:

When I try to run it on the server, it comes up with this error:

Caused by: javax.naming.NameNotFoundException: Name search.url is not bound in this Context

server.xml中的此项似乎无济于事:

This entry in server.xml doesn't seem to help:

(从Eclipse/STS中可以看到)

There's also an entry in (as seen from Eclipse/STS)

Tomcat v6.0 Server at localhost
   Catalina
     localhost
         ROOT.xml

<Context path="" reloadable="true" docBase="C:/myworkspace32/myAppName/WebContent">
        <ResourceLink global="search.url" name="search.url" type="java.lang.String"/>
</Context>

但是，这似乎没有影响.

However, this seem to have no impact.

推荐答案

以下是从tomcat访问JNDI资源的步骤

Here are the steps to access JNDI resource from tomcat

1. 在server.xml中创建jndi资源

1. Create jndi resource in server.xml

<Resource global="search.url" name="search.url" type="java.lang.String" />

在context.xml中创建链接，以便所有Web应用程序都可以访问它.

Create the link in context.xml so that its accessible by all the web application.

<ResourceLink name="search.url"  global="search.url" auth="Container" type="java.lang.String" />

使用spring bean或jee标签注入jndi

Use spring bean or jee tag to inject the jndi

<bean id="searchUrl" class="org.springframework.jndi.JndiObjectFactoryBean">
 <property name="jndiName" value="java:comp/env/search.url"/>
</bean>

可以避免使用jee contatiner标签指定环境，如下所示

you can avoid specify the environment by using jee contatiner tag as follows

 <jee:jndi-lookup id="searchUrl" jndi-name="search.url" expected-type="java.lang.String" />
