普通類注入不進(jìn)spring bean的解決方法
解決問題:我在做移動(dòng)端accessToken的使用遇到一個(gè)問題,就是普通類死活注入不進(jìn)去spring bean,我和同事雷杰通過各種注解,xml配置搞了好久都搞不定,這里插個(gè)眼,有空補(bǔ)一下spring,得深入研究一下
解決辦法:后面通過一個(gè)spring工具類搞定,這里貼上代碼
1、引入這個(gè)springUtil類貼上SpringUtils代碼:
package com.dt.base.weixin.util;import org.springframework.aop.framework.AopContext;import org.springframework.beans.BeansException;import org.springframework.beans.factory.NoSuchBeanDefinitionException;import org.springframework.beans.factory.config.BeanFactoryPostProcessor;import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;import org.springframework.stereotype.Component;/** * @Description: spring工具類 方便在非spring管理環(huán)境中獲取bean * @author: ZhangChongHu * @Date: 2020/12/8 17:23 * @Copyright: Xi’an Dian Tong Software Co., Ltd. All Rights Reserved. * @Version 1.0 */@Componentpublic final class SpringUtils implements BeanFactoryPostProcessor{ /** Spring應(yīng)用上下文環(huán)境 */ private static ConfigurableListableBeanFactory beanFactory; @Override public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException { SpringUtils.beanFactory = beanFactory; } /** * 獲取對(duì)象 * * @param name * @return Object 一個(gè)以所給名字注冊(cè)的bean的實(shí)例 * @throws BeansException * */ @SuppressWarnings('unchecked') public static <T> T getBean(String name) throws BeansException { return (T) beanFactory.getBean(name); } /** * 獲取類型為requiredType的對(duì)象 * * @param clz * @return * @throws BeansException * */ public static <T> T getBean(Class<T> clz) throws BeansException { T result = (T) beanFactory.getBean(clz); return result; } /** * 如果BeanFactory包含一個(gè)與所給名稱匹配的bean定義,則返回true * * @param name * @return boolean */ public static boolean containsBean(String name) { return beanFactory.containsBean(name); } /** * 判斷以給定名字注冊(cè)的bean定義是一個(gè)singleton還是一個(gè)prototype。 如果與給定名字相應(yīng)的bean定義沒有被找到,將會(huì)拋出一個(gè)異常(NoSuchBeanDefinitionException) * * @param name * @return boolean * @throws NoSuchBeanDefinitionException * */ public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException { return beanFactory.isSingleton(name); } /** * @param name * @return Class 注冊(cè)對(duì)象的類型 * @throws NoSuchBeanDefinitionException * */ public static Class<?> getType(String name) throws NoSuchBeanDefinitionException { return beanFactory.getType(name); } /** * 如果給定的bean名字在bean定義中有別名,則返回這些別名 * * @param name * @return * @throws NoSuchBeanDefinitionException * */ public static String[] getAliases(String name) throws NoSuchBeanDefinitionException { return beanFactory.getAliases(name); } /** * 獲取aop代理對(duì)象 * * @param invoker * @return */ @SuppressWarnings('unchecked') public static <T> T getAopProxy(T invoker) { return (T) AopContext.currentProxy(); }}
貼上調(diào)用得方法:
注意:調(diào)用getValidator()方法直接返回得是 AgentCfgDao agentCfgDao ,相當(dāng)于
@Autowired private AgentCfgDao agentCfgDao;

總結(jié):bug是搞定了,但是基礎(chǔ)知識(shí)還要補(bǔ),打卡現(xiàn)在是2020/12/16寫得博客,那天把這里得知識(shí)補(bǔ)了,在回來留痕。
