监听中如何调用业务类

在监听中是无法直接根据注解或者是new调用业务逻辑层的，那么需要通过spring的appliactionContext来获取

一、编写一个工具类SpringUtils

import org.springframework.beans.BeansException;

import org.springframework.context.ApplicationContext;

import org.springframework.context.ApplicationContextAware;

import org.springframework.stereotype.Service;

@Service

public class SpringUtils implements ApplicationContextAware {
private static ApplicationContext applicationContext = null;

public static Object getBean(String name) {
if (applicationContext == null) {
return
null;
}
return applicationContext.getBean(name);
}

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

}

二、调用方式

@Service(value="testServiceImpl")

public class TestServiceImpl extends BaseServiceImpl<Test> implements

TestServiceI

TestServiceI tService = (TestServiceI)SpringUtils.getBean("testServiceImpl");
