Spring Util：通过注释将属性注入到bean中 [英] Spring Util:Properties Injection via Annotations into a bean

问题描述

如果我在我的Spring XML中设置了2个.properties文件：

If I have 2 .properties files setup in my Spring XML as so:

<util:properties id="serverProperties" location="file:./applications/MyApplication/server.properties"/>
<util:properties id="someConfig" location="file:./applications/MyApplication/config.properties"/>

如何通过注释将这些属性文件注入到具有 java的bean中。 util.Properties ？

How can I inject via annotations these properties files into a bean with java.util.Properties?

如何通过Spring注释获取特定的属性？

How can I grab specific properties via Spring annotations?

干杯！

推荐答案

@Autowired
@Qualifier("serverProperties")
private Properties serverProperties;
@Autowired
@Qualifier("someConfig")
private Properties otherProperties;

或

@Resource(name = "serverProperties")
private Properties serverProperties;
@Resource(name = "someConfig")
private Properties otherProperties;

通常，@Autowired用于Spring中的按类型自动装配，而@Resource用于-名称。 @ Autowired + @限定符可以按名称自动布线方式加倍，但它实际上用于通过类型自动布线来实现微调类型。

Typically, @Autowired is used for by-type autowiring in Spring, and @Resource is used for by-name. @Autowired+@Qualifier can double as by-name autowiring, but it's really meant for by-type autowiring with the ability to fine-tune the type.
