解決同一個應用下包循環依賴問題

情景:做項目遇到一個情景,同一個應用中,有A包和B包,本來是A包中方法調用B包的方法,現在要求B包中方法調用A包中方法

解決方案:

利用ApplicationContextEvent事件

監聽方:

public class AccountChangeEvent extends ApplicationContextEvent {

    @Getter
    private final String param;
    /**
     * Create a new ContextStartedEvent.
     *
     * @param source the {@code ApplicationContext} that the event is raised for
     *               (must not be {@code null})
     */
    public AccountChangeEvent(ApplicationContext source, String param) {
        super(source);
        this.param=param;
    }
}

調用方:

@Resource
private ApplicationContext applicationContext;

//發送事件
applicationContext.publishEvent(new AccountChangeEvent(applicationContext,"這是參數"));
