In this case you could instantiate the Spring container in a similar fashion as described above for the EJB tier.
在此情况下，您可以按照上面针对ejb层描述的类似方式实例化spring容器。
We do not like to pass the uid and PWD as parameters or store in some objects to pass from the Web tier to the EJB tier.
我们不想将uid和pwd作为参数传递，或者存储到一些从We b层到ejb层传递的对象中。
Implementing an EJB tier, though not required, lays the foundation for creating a highly scalable, distributed application architecture.
虽然没有要求实现ejb层，但这样做可以为建立高度可伸缩的分布式应用程序架构提供基础。
