非註解方式獲取spring bean物件以及配置值

spring bean物件可以通過@autowired 或者@resource等註解方式獲取；spring配置值可以通過@value註解獲取。通過註解方式獲取很方便，但是有一定侷限 。本文主要介紹通過非註解的方法獲取bean物件以及配置方法。

獲取bean 物件主要是獲取spring 容器的上下文

package com.hsc.spring.study.context;

import org.springframework.beans.bean***ception;
import org.springframework.stereotype.component;
/** * created by hsc on 17/4/9.
*/@component
public
class
springcontext
implements
//spring應用上下文環境
private
@override
public
void
}/**
* 獲取物件
**@param name
*@return object 乙個以所給名字註冊的bean的例項
*@throws bean***ception
*/public
static object getbean(string name) throws bean***ception 
}

package com.hsc.spring.study.context;

import org.springframework.context.embeddedvalueresolveraware;
import org.springframework.stereotype.component;
import org.springframework.util.stringvalueresolver;
/** * created by hsc on 17/4/9.
*/@component
public
class
propertiesutils
implements
embeddedvalueresolveraware 
public
static string getpropertiesvalue(string name) 
}
