arthas获取spring bean
写一个工具Util
package com.example.lredisson.util;import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;/*** @author lixiognl -c 18b4aac2 '#context=@com.example.lredisson.util.OSSSpringUtil@getContext(),#context.getBean("testModel").getAge()'* */@Component
public class OSSSpringUtil implements ApplicationContextAware {private static ApplicationContext context;@Overridepublic void setApplicationContext(ApplicationContext applicationContext) throws BeansException {context = applicationContext;}public static <T> T getBean(String beanName, Class<T> clazz) {return context.getBean(beanName, clazz);}public static Object getBean(String beanName) {return context.getBean(beanName);}public static ApplicationContext getContext() {return context;}
}
结果
sc -d com.example.lredisson.util.OSSSpringUtilclass-info com.example.lredisson.util.OSSSpringUtil code-source /Users/admin/work/llixi/lredisson/target/classes/ name com.example.lredisson.util.OSSSpringUtil isInterface false isAnnotation false isEnum false isAnonymousClass false isArray false isLocalClass false isMemberClass false isPrimitive false isSynthetic false simple-name OSSSpringUtil modifier public annotation org.springframework.stereotype.Component interfaces org.springframework.context.ApplicationContextAware super-class +-java.lang.Object class-loader +-sun.misc.Launcher$AppClassLoader@18b4aac2 +-sun.misc.Launcher$ExtClassLoader@6aceb1a5 classLoaderHash 18b4aac2 Affect(row-cnt:1) cost in 28 ms.

@Integer[20]
arthas验证先生代码版本
直接找到需要判断的class，用jad反编译看看结果最简单了啊。
