How to inject a string in a JAVA servlet´s method?
问题
我是新手使用依赖注入。有人可以告诉我如何配置一个Servlet来注入一个指向文件的字符串URI吗？方法签名如下：
@Inject
public void setCar(String value)
{
CarUri =value;
}
提前感谢！

你可以尝试注入@Named字段
// 在模块内部
@Provides
@Named("CarURI")
public String carURI() {
return "URI";
}
@Inject
public void setCar(@Named("CarURI") String value) {
CarUri = value;
}

英文:
You can try injecting @Named fields
// inside module
@Provides
@Named("CarURI")
public String carURI() {
return "URI";
}
@Inject
public void setCar(@Named("CarURI") String value) {
CarUri = value;
}
