Question

我有一个具有以下依赖关系的层次结构：

Base(Timer timer)

    Timer(PublisherService service, BaseDao userDao, DataProcessor processor)

DataProcessor中还有其他依赖项，但我不会那么远，因为看起来我的错误很早就发生了。与该依赖图相对应，我有以下Spring配置：

<bean id="base" class="com.apps.consumer.Base">
    <constructor-arg name="timer" ref="consumerTimerTask"/>
</bean>

<bean id="consumerTimerTask" class="com.apps.consumer.ConsumerTimerTask">
    <constructor-arg name="service" ref="tradePublisherService"/>
    <constructor-arg name="userDao" ref="userDao"/>
    <constructor-arg name="consumerDataProcessor" ref="consumerDataProcessor"/>
</bean>

<bean id="tradePublisherService" class="com.apps.consumer.common.TradePublisherService"/>

<bean id="userDao" class="com.apps.dao.UserDao"/>

<bean id="consumerDataProcessor" class="com.apps.consumer.ConsumerDataProcessor">
    <!-- Additional constructor-args here for this guy -->
</bean>

在我的应用程序的顶层，我将运行：

ApplicationContext context = new ClassPathXmlApplicationContext("spring-configuration.xml");

Base consumerBase = context.getBean("base", Base.class);

当我按照调试时发现Timer已成功初始化。。。有些。在Timer完全解析并注入Base之前，我会回复以下内容：

我将它追溯到Main，这是我的堆栈跟踪中唯一的类。

删除Java和XML中的所有三个构造函数参数解决了这个问题，但是引入3个构造函数参数中的任何一个都会将其重新引出。例如，依赖图对DataProcessor更深一些，但即使我只使用BaseDao作为构造函数args，它本身没有依赖关系，我也会收到此错误。

知道这里发生了什么吗？我已经尝试了构造函数args的各种排列，创建了新的接口实现，以防我现有的东西导致问题冒出来，几乎所有的一切都不好意思，只是更仔细地从头开始重写。

编辑：

public class Base {
    private TimerTask consumerTimerTask;

    private static Logger logger = LoggerFactory.getLogger(Base.class);

    public Base(TimerTask timer) {
        this.consumerTimerTask = timer;
    }

    /**
     * Initialize the timer.
     * @throws Exception
     */
    public void initialize() throws Exception {
        final int updateFrequency = 10000;

        // Once all fields have been generated and prefs read, initialize the update process every number of seconds.
        final Timer updateTimer = new Timer();

        updateTimer.scheduleAtFixedRate(this.consumerTimerTask, 0, updateFrequency);

        logger.info("Base initialized successfully!");
    }
}

由于代码是继承的，我忽略了以下依赖的版本：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
</dependency>

设置<spring.version>4.2.4.RELEASE</spring.version>解决了问题。
