java获取xml文件中bean（包括自定义）

xml中声明自定义的bean和引入bean

引入bean中的内容，自定义bean代码随意

package com.shiro.utils;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.NoSuchBeanDefinitionException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

/**
 * 上下文util
 * @author eadela
 *
 */
public class SpringContextUtil implements ApplicationContextAware {
	
	private static ApplicationContext applicationContext; 

	@Override
	public void setApplicationContext(ApplicationContext applicationContext)
			throws BeansException {
		SpringContextUtil.applicationContext = applicationContext;
	}

	public static ApplicationContext getApplicationContext() {
		return applicationContext;
	}

	public static Object getBean(String name) throws BeansException {
		try {
			return applicationContext.getBean(name);
		} catch (Exception e) {
			throw new RuntimeException("获取的Bean不存在！");
		}
	}

	public static  T getBean(String name, Class requiredType)
			throws BeansException {
		return applicationContext.getBean(name, requiredType);
	}

	public static boolean containsBean(String name) {
		return applicationContext.containsBean(name);
	}

	public static boolean isSingleton(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.isSingleton(name);
	}

	public static Class getType(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.getType(name);
	}

	public static String[] getAliases(String name)
			throws NoSuchBeanDefinitionException {
		return applicationContext.getAliases(name);
	}
}

在需要的地方引入自定义bean

public class CusUtil {
	
	final static CustomBean cus = SpringContextUtil.getBean("customBean", CustomBean.class);
}

这样在CusUtil中就可以引用 CustomBean 内的内容
