通过注释和 xml 上下文连接 Spring bean
我有以下 Spring 服务：
@Service
public class Worker {
@Autowired
private MyExecutorService executor;
@Autowired
private IRun run;
private Integer startingPoint;
// Remainder omitted
}
现在我想通过 .properties 文件加载 startingPoint。
是否可以同时通过注释和 xml 上下文连接 Spring 服务？
也许是这样的：
<bean id="worker" class="Worker">
<property name="startingPoint">
<value>${startingPoint}</value>
</property>
</bean>
startingPoint 通过 xml 上下文文件连接，其他所有内容都会自动连接。
I've got the following Spring service:
@Service
public class Worker {
@Autowired
private MyExecutorService executor;
@Autowired
private IRun run;
private Integer startingPoint;
// Remainder omitted
}
Now I want to load the startingPoint through a .properties file.
Is it possible to wire a Spring service through annotations and an xml context at the same time?
Maybe something like this:
<bean id="worker" class="Worker">
<property name="startingPoint">
<value>${startingPoint}</value>
</property>
</bean>
startingPoint is wired through the xml context file, everything else gets auto-wired.

是的！这绝对是可能的，如果您无法避免使用一点 XML，那么这是一个好方法。只需保留所有带注释的字段未指定，它们就会神奇地自动注入。
不过为了清楚起见，我相信您必须为您的 Integer 字段提供一个设置器。 Spring 不想通过 XML 描述符直接访问并设置字段。
Yes! This is most definitely possible, and it's a good way to go if you can't get around using a little bit of XML. Just leave all your annotated fields unspecified, and they'll get injected auto-magically.
Though just to be clear, I believe that you'll have to provide a setter for your Integer field. Spring doesn't want to reach in directly and set fields via the XML descriptor.
