Unity是一个轻量级，可扩展的依赖注入容器，支持构造函数，属性和方法调用注入。

Unity is a lightweight, extensible dependency injection container with support for constructor, property, and method call injection.

在IoC设置中，这些方面通常由一个ioc容器处理，比如，该容器通过调用setter方法将这些依赖项注入组件。

In an IoC setup, these aspects are normally handled by an IoC container that injects the dependencies into the component by calling a setter method, for example.

必须对注入的模块上下文调用方法。

A method has to be called on the injected module context.

在这里，DBWriter是接口类，不需要调用DBWritersetUp方法，因为EntityManager将直接注入到捆绑包中。

Here, DBWriter is the interface class. There is no requirement to call the DBWriter setUp method because the EntityManager will be directly injected into the bundle.

在这个方法中，我们可以在调用原方法之前或之后注入自己的代码。

In this method, custom code can be injected before or after invoking the original methods.

通过注入对代理对象的引用而不是注入实际的EJB远程接口存根，Spring还可以捕获在业务方法调用过程中引发的异常。

Spring can also catch exceptions thrown during business method calls by injecting a reference to a proxy object instead of the actual EJB remote interface stub.

首先，您获得一个指向simplebean . xml的对象，然后，您使用编组器对象(通过Spring的依赖项注入实例化)调用marshal方法。

Then, you use the marshaller object (which was instantiated by Spring's dependency injection) to invoke the marshal method. This method requires two parameters.
