记录一下，在springboot中配置ApplicationContext。

直接上代码~

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

/**
 * Springboot 获取上下文<br/>

@Component
public class SpringApplicationContext implements ApplicationContextAware {
     
    private static ApplicationContext applicationContext;

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

    /**
     * 获取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);
    }

    /**
     * 通过class获取Bean.
     * 
     * @param clazz
     * @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
     * @return
     */
    public static <T> T getBean(String name, Class<T> clazz) {
        return getApplicationContext().getBean(name, clazz);
    }

}

再来个main方法试试

    public static void main(String[] args) {

        UserService userService = SpringApplicationContext.getBean(UserService.class);

        EntityWrapper<UserDto> entityWrapper = new EntityWrapper<>();
        entityWrapper.eq("sex", 1);
        List<UserDto> userList = userService.selectList(entityWrapper);

        if (null != userList && !userList.isEmpty()) {
            for (UserDto userDto : userList) {
                System.out.println(userDto.toString());
            }
        }
    }
