MethodInvokingFactoryBean的應用html
MethodInvokingFactoryBean配置system properties java
以下所示,spring
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd"> <bean id="systemProps" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> <property name="targetObject" value="#{@systemProperties}" /> <property name="targetMethod" value="putAll" /> <property name="arguments"> <util:properties> <prop key="myprop1">myvalue1</prop> <prop key="myprop2">myvalue2</prop> <prop key="mypropN">myvalueN</prop> </util:properties> </property> </bean> </beans>
根據Spring SPEL的文檔介紹說,systemProperties是一個預約義好的對象實例,這裏的targetObject直接表示使用該實例,爲java.util.Properties對象實例,targetMethod表示調用的方法爲putAll。表示把上面的key-value值對放入systemProperties中。code
MethodInvokingFactoryBean還有其餘用法請參照xml
