如何加载XML文件中定义的配置参数？

Question

我想在项目A中使用项目B，我想使用XML配置文件将一些配置参数传递到项目A。< / p>

换句话说，假设我正在实现类似我自己的spring-data-mongo（例如），我想从我已定义的配置文件中配置我的Mongo实例，如下所示：

<mongo: mongo host = "$ {mongo.hostname}" port = "$ {mongo.port}">
<mongo: options connections-per-host = "8"
threads-allowed-to-block-for-connection-multiplier = "4"
connect-timeout = "15000"
max-wait-time = "1500"
auto-connect-retry = "true"
socket-keep-alive = "true"
socket-timeout = "60000"
slave-ok = "true"
write-number = "1"
write-timeout = "0"
write-fsync = "false" />

我如何实现这样的目标？
