Need to load multiple properties at the same time, there is basically no reference for the above, re-written one
<!-- 属性文件获取 -->
<bean id="propertyConfigurer" class="com.shiro.utils.ExtPropertyPlaceholderConfigurer">
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
<property name="ignoreResourceNotFound" value="true" />
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
<value>classpath*:ha_redis.properties</value>
</list>
</property>
</bean>
The specific implementation of the bean is as follows
package com.shiro.utils;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.beans.factory.config.PropertyPlaceholderConfigurer;
/**
* 扩展属性文件读取
*
* @author
*
*/
public class ExtPropertyPlaceholderConfigurer extends PropertyPlaceholderConfigurer {
private static Map<String, Object> ctxPropertiesMap;
@Override
protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props)
throws BeansException {
super.processProperties(beanFactoryToProcess, props);
ctxPropertiesMap = new HashMap<String, Object>();
for (Object key : props.keySet()) {
String keyStr = key.toString();
String value = props.getProperty(keyStr);
ctxPropertiesMap.put(keyStr, value);
}
}
public Object getContextProperty(String name) {
return ctxPropertiesMap.get(name);
}
}
So that you can reference multiple properties at the same time
