注册监听类

package com.cqemme.activitiservice.config;


import org.activiti.engine.delegate.event.ActivitiEventListener;
import org.activiti.spring.SpringProcessEngineConfiguration;
import org.activiti.spring.boot.ProcessEngineConfigurationConfigurer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

@Component
public class ActivitiConfig implements ProcessEngineConfigurationConfigurer {

    @Autowired
    private ComActivitiEventListener comActivitiEventListener;

    @Override
    public void configure(SpringProcessEngineConfiguration processEngineConfiguration) {

        List<ActivitiEventListener> activitiEventListener=new ArrayList<ActivitiEventListener>();

        activitiEventListener.add(comActivitiEventListener);//配置全局监听器

        processEngineConfiguration.setEventListeners(activitiEventListener);

    }

}

普通类拿到容器bean

package com.cqemme.activitiservice.config;

        this.applicationContext = applicationContext;
    }

     *
     * @return
     */
    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    /**
     * 通过name获取 Bean.
     *
     * @param name
     * @return
     */
    public static Object getBean(String name) {
        return getApplicationContext().getBean(name);
    }

    /**

     *
     * @param clazz
     * @param <T>
     * @return
     */
    public static <T> T getBean(Class<T> clazz) {
        return getApplicationContext().getBean(clazz);
    }

    /**
     * 通过name,以及Clazz返回指定的Bean
     *
     * @param name
     * @param clazz
     * @param <T>
     * @return
     */
    public static <T> T getBean(String name, Class<T> clazz) {
        return getApplicationContext().getBean(name, clazz);
    }
}
