Question

我希望能够在一次无国籍会议上这样做。

@Resource(name="mycustomthingie") private CustomClass stuff;

The value injected is context (speak: Thread) dependant. I guess this would be possible if I bind an ObjectFactory into the JNDI Context that delivers the correct Object when requested.

As I understand it for this to work I would have to add the resource to the "java:comp" JNDI context, but this is appearantly not allowed by the EE5 specification. Is there a subcontext in which I am allowed to write or is there another way to get something similar to work ?

Answer 1

this article fromInfoQ that does a good work at summarying the Resource Injection part of the JSR-244/ (我看不到这一点的某个地方:

Injection is limited only to first class constructs defined in the Java EE platform, including:

SessionContext object

DataSources object

UserTransaction

EntityManager interface

TimerService interface

Other enterprise beans

Web services

Message queues and topics

Connection factories for resource adaptes

Environment entries limited to String, Character, Byte, Short, Integer, Long, Boolean, Double, and Float.

The injection facilities in Java EE 5 do not apply to any POJO (which is often criticized by the Spring community) [...]

因此,如果您的<代码>CustomClass不是管理的组成部分,不是简单的环境条目(似乎就是如此),那么我就不认为你可以注射。
