<util:properties> equivalent in java based configuration for spring
提问by Yves Nicolas
What would be the equivalent in java based configuration of XML based spring configuration
在基于 Java 的基于 XML 的 spring 配置的配置中的等价物是什么
<util:properties id="mapper" location="classpath:mapper.properties" />
To then be able to use this specific property object in code like :
然后能够在如下代码中使用这个特定的属性对象：
@Resource(name = "mapper")
private Properties myTranslator;
Looking at the doc, I looked at the
看着文档，我看了看
@PropertySource
annotation but it seems to me that the particular propertyfile will not be able to be accessed individually from the Environment object.
注释，但在我看来，特定的属性文件将无法从 Environment 对象中单独访问。

Very simply, declare a PropertiesFactoryBean.
很简单，声明一个PropertiesFactoryBean.
@Bean(name = "mapper")
public PropertiesFactoryBean mapper() {
PropertiesFactoryBean bean = new PropertiesFactoryBean();
bean.setLocation(new ClassPathResource("com/foo/jdbc-production.properties"));
return bean;
}
In the documentation here, you'll notice that before they made <util:properties>, they used to use a PropertiesFactoryBeanas such
在文档在这里，你会发现，他们作出之前<util:properties>，他们曾经用PropertiesFactoryBean这样
<!-- creates a java.util.Properties instance with values loaded from the supplied location -->
<bean id="jdbcConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="location" value="classpath:com/foo/jdbc-production.properties"/>
</bean>
Converting that to Java config is super easy as shown above.
如上所示，将其转换为 Java 配置非常简单。
