hprose spring集成 -- 让hproseservlet 使用spring的 bean

使用第一添加springcontextutil到项目中，这样没有session 和 servlet环境我们只根据bean id我们也可以获取到 spring 维护的 bean
package com.eluotuo.common.spring;import org.springframework.beans.BeansException;import org.springframework.beans.factory.NoSuchBeanDefinitionException;import org.springframework.context.ApplicationContext;import org.springframework.context.ApplicationContextAware;import org.springframework.stereotype.Component;import com.eluotuo.common.util.Logger;/** * spring上下文配置 * @author Mingchenchen * */@Componentpublic class SpringContextUtil implements ApplicationContextAware { private static Logger logger = Logger.getLogger(SpringContextUtil.class); private static ApplicationContext applicationContext = null; public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { logger.info("------SpringContextUtil setApplicationContext-------"); SpringContextUtil.applicationContext = applicationContext; } public static ApplicationContext getApplicationContext() { return applicationContext; } /** * 注意 bean name默认 = 类名(首字母小写) * 例如: A8sClusterDao = getBean("k8sClusterDao") * @param name * @return * @throws BeansException */ public static Object getBean(String name) throws BeansException { return applicationContext.getBean(name); } /** * 根据类名获取到bean * @param <T> * @param clazz * @return * @throws BeansException */ @SuppressWarnings("unchecked") public static <T> T getBeanByName(Class<T> clazz) throws BeansException { try { char[] cs=clazz.getSimpleName().toCharArray(); cs[0] += 32;//首字母大写到小写 System.out.println(applicationContext.getBean(String.valueOf(cs))); return (T) applicationContext.getBean(String.valueOf(cs)); } catch (Exception e) { e.printStackTrace(); return null; } } public static boolean containsBean(String name) { return applicationContext.containsBean(name); } public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException { return applicationContext.isSingleton(name); }}接着把web.xml 里面配置的 hprose的servlet改为我重写过的。
