Spring_手动获取Bean

1.SpringContextHolder.java

package com.lkb.util;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

/**
 * SpringContextHolder
 *
 * @author Lilin
 * @date 2015/12/30
*/
public class SpringContextHolder implements ApplicationContextAware {
private static ApplicationContext applicationContext;

/**
     * 实现ApplicationContextAware接口的context注入函数, 将其存入静态变量.
*/
public void setApplicationContext(ApplicationContext applicationContext) {
        SpringContextHolder.applicationContext = applicationContext; // NOSONAR
    }

/**
     * 取得存储在静态变量中的ApplicationContext.
*/
public static ApplicationContext getApplicationContext() {
        checkApplicationContext();
return applicationContext;
    }

/**
     * 从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型.
*/
    @SuppressWarnings("unchecked")
public static <T> T getBean(String name) {
        checkApplicationContext();
return (T) applicationContext.getBean(name);
    }

/**
     * 从静态变量ApplicationContext中取得Bean, 自动转型为所赋值对象的类型.
*/
    @SuppressWarnings("unchecked")
public static <T> T getBean(Class<T> clazz) {
        checkApplicationContext();
return (T) applicationContext.getBeansOfType(clazz);
    }

/**
     * 清除applicationContext静态变量.
*/
public static void cleanApplicationContext() {
        applicationContext = null;
    }

private static void checkApplicationContext() {
if (applicationContext == null) {
throw new IllegalStateException("applicaitonContext未注入,请在applicationContext.xml中定义SpringContextHolder");
        }
    }
}

 

2.application.xml

<aop:aspectj-autoproxy proxy-target-class="true"/>

 <aop:aspectj-autoproxy proxy-target-class="true"/>

<bean class="com.lkb.util.SpringContextHolder" lazy-init="false" />

 

3.调用

AuthServiceImpl authService =SpringContextHolder.getBean("authServiceImpl");
