Spring boot添加配置类@Configuration并初始化@Bean，@Resource和@Autowired都为null

大写加黑，找了好久@Resource和@Autowired都依赖不到创建的bean的原因： @Bean的方法名即是创建的Bean名称

import org.activiti.engine.ProcessEngines;

import org.activiti.engine.RepositoryService;

import org.activiti.engine.TaskService;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

@Configuration

public class ActivitiConfig {

    @Bean

    public RepositoryService repositoryService() {

        System.out.println("初始化RepositoryService");

        RepositoryService repositoryService = ProcessEngines.getDefaultProcessEngine().getRepositoryService();

        System.out.println(repositoryService);

        return repositoryService;

    }

    @Bean

    public TaskService taskService() {

        System.out.println("初始化TaskService");

        TaskService taskService = ProcessEngines.getDefaultProcessEngine().getTaskService();

        System.out.println(taskService);

        return taskService;

    }

}

测试类：

import org.activiti.engine.RepositoryService;

import org.activiti.engine.TaskService;

import org.junit.Test;

import org.junit.runner.RunWith;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

@SpringBootTest

@RunWith(SpringRunner.class)

public class DemoApplicationTests {

    @Autowired

    private RepositoryService repositoryService;

    @Resource

    private TaskService taskService;

    @Test

    public void getProcessEngine() {

        System.out.println("获取RepositoryService：" + repositoryService);

        System.out.println("获取TaskService：" + taskService);

    }

}
