Picocontainer中的JSR-330支持:@Inject ... @Named(" xxx) [英] JSR-330 support in Picocontainer : @Inject ... @Named("xxx)

问题描述

我们找到了类似的代码

private String string = "Not injected.";

@Inject
public void setString(@Named("s") String s) {
    this.string = s;
}

(利用JSR-330批注)对于传递"s"的字符串值非常有用.对于使用哪个容器，我们也希望尽可能灵活，因此也希望使用Picocontainer.

(utilitzing JSR-330 annotations) to be very useful to pass in a string value for "s". We would like to be as flexible as possible regarding which container to use, hence also Picocontainer.

按照书面规定，Picocontainer会默默地忽略注入.我将如何提示PicoContainer注入例如绳子注入了！"在这里?

As written, Picocontainer silently ignores the inject. How would I hint to PicoContainer to inject e.g. "String injected!" here?

推荐答案

稳定的pico 2.x不完全支持JSR-330(您的特殊情况)，而pico 3.x则具有. 无论如何，@named并不是使用picocontainer功能的好方法，也不是针对以IoC为中心的应用程序的好设计.如果您使用这些东西，可能不需要pico.

Stable pico 2.x does not have full support for JSR-330 (your particular case), pico 3.x will have. Anyway, @named is not a good way to use picocontainer powers and not a good design for IoC centered app at all. Probably you don't need pico, if you use this stuff.
