获取spring的properties内容

package cn.iqoo.sms;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;
import org.springframework.stereotype.Component;

import java.util.Properties;

public class PropertyConfigurer extends PropertyPlaceholderConfigurer {
    private Properties props;

    @Override
    protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props)
            throws BeansException {
        super.processProperties(beanFactoryToProcess, props);
        this.props = props;
    }

    public String getProperty(String key) {
        return this.props.getProperty(key);
    }

    public String getProperty(String key, String defaultValue) {
        return this.props.getProperty(key, defaultValue);
    }

    public Object setProperty(String key, String value) {
        return this.props.setProperty(key, value);
    }
}

    <bean id="propertyConfigurer" class="cn.iqoo.sms.PropertyConfigurer">
        <property name="ignoreUnresolvablePlaceholders" value="true"/>
        <property name="ignoreResourceNotFound" value="true"/>
        <property name="locations">
            <list>
                <value>classpath:app.properties</value>
            </list>
        </property>
    </bean>

 

然后就简单了：

propertyConfigurer.getProperty("keyname");
