Question

我想在server.xml中设置一个基本上是url的属性，并将其注入我的spring bean中。但它似乎没有用，任何想法

在我的春天xml

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

在我的web.xml中我有

网址网址 java.lang.String中容器

在我的server.xml中我有

<GlobalNamingResources>
    <Environment name="url" type="java.lang.String" value="http://localhost/myapp"/>

我的春豆有以下几点：

@Resource(name="url")
private String url;

以上操作不起作用，运行我的网络应用时出现以下错误：

我的第一个建议是不使用JNDI进行此类操作，而是使用属性文件，因为它们更容易处理，而Spring对它们提供了很棒的支持。

话虽如此，如果你绝对需要JNDI，我建议你看一下this SO帖子。如果您遵循该响应，则可以使用@Value批注来解析JNDI查找

使用spring jndi在tomcat server.xml中设置属性
