说明

Spring 针对反射提供的工具类 ReflectionUtils

示例

SpringContextsUtil.java

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

 */
@Component
public class SpringContextsUtil implements ApplicationContextAware {
 
    private ApplicationContext applicationContext;
 
    public Object getBean(String beanName) {
        return applicationContext.getBean(beanName);
    }
 
    public <T> T getBean(String beanName, Class<T> clazs) {
        return clazs.cast(getBean(beanName));
    }
    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        this.applicationContext = applicationContext;
    }
}

ReInvokeService.java

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.ReflectionUtils;
 
import java.lang.reflect.Method;

@Service
public class ReInvokeService {
    @Autowired
    private SpringContextsUtil springContextsUtil;
 
    public void reInvoke(String beanName,String methodName,String[] params){
        Method method = ReflectionUtils.findMethod(springContextsUtil.getBean(beanName).getClass(), methodName, String.class, String.class, Boolean.class,String.class);
