Answer 1

参见public Producer（BlockingQueue q，int year，int qtr）你没有声明类型的工厂实例限定bean 'java.util.concurrent.BlockingQueue'BlockingQueue 您可以添加工厂方法或工厂bean

@Bean
public BlockingQueue<OutputDocument> createBlockingQueue() {

}

Answer 2

消息很明确：找不到BlockingQueue类型的bean。

您将课程注释为

@Component
public class Producer implements Runnable

因此Spring会尝试初始化这种单例bean。

当你声明一个构造函数时：

public Producer(BlockingQueue<OutputDocument> q, int year,int qtr) {
    this.queue = q;
    this.year=year;
    this.qtr=qtr;

}

所以Spring会尝试使用该构造函数来初始化bean。

但是找不到第一个参数BlockingQueue<OutputDocument> q因此异常。

您需要提供该类型的bean：

@Bean
BlockingQueue<OutputDocument> createBlockingQueue() {
...
}

提供此bean之后，spring也会抱怨year，qtr。所以你必须为它提供这些bean。的修改

您的依赖关系管理存在严重问题。

如果您将Producer声明为@Component，则应将其注入Migration课程，而不是手动创建。
