public class PropertySourcesPlaceholderConfigurer extends PlaceholderConfigurerSupport implements EnvironmentAware
Specialization ofPlaceholderConfigurerSupport
that resolves ${...} placeholders within bean definition property values and@Value
annotations against the current SpringEnvironment
and its set ofPropertySources
.This class is designed as a general replacement for
PropertyPlaceholderConfigurer
introduced in Spring 3.1. It is used by default to support theproperty-placeholder
element in working against the spring-context-3.1 or higher XSD, whereas spring-context versions <= 3.0 default toPropertyPlaceholderConfigurer
to ensure backward compatibility. See the spring-context XSD documentation for complete details.Any local properties (e.g. those added via
PropertiesLoaderSupport.setProperties(java.util.Properties)
,PropertiesLoaderSupport.setLocations(org.springframework.core.io.Resource...)
et al.) are added as aPropertySource
. Search precedence of local properties is based on the value of thelocalOverride
property, which is by defaultfalse
meaning that local properties are to be searched last, after all environment property sources.See
ConfigurableEnvironment
and related javadocs for details on manipulating environment property sources.- 从以下版本开始:

setPropertySources
public void setPropertySources(PropertySources propertySources)
Customize the set ofPropertySources
to be used by this configurer.Setting this property indicates that environment property sources and local properties should be ignored.
setEnvironment
public void setEnvironment(Environment environment)
PropertySources
from the givenEnvironment
will be searched when replacing ${...} placeholders.
postProcessBeanFactory
public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException
Processing occurs by replacing ${...} placeholders in bean definitions by resolving each against this configurer's set ofPropertySources
, which includes:- all environment property sources, if an
Environment
is present - merged local properties, if anyhavebeenspecified
- any property sources set by calling
setPropertySources(org.springframework.core.env.PropertySources)
If
setPropertySources(org.springframework.core.env.PropertySources)
is called, environment and local properties will be ignored. This method is designed to give the user fine-grained control over property sources, and once set, the configurer makes no assumptions about adding additional sources.- 指定者:
