1.添加pom依赖

<dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <scope>test</scope>
            </dependency>
    
            
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-test</artifactId>
                <version>5.1.1.RELEASE</version>
            </dependency>

2.添加test类

3.配置test类

4.AccountItemServiceTest类

public class AccountItemServiceTest extends CommonService {
    
        @Test
        public void queryAccountingSubject(){
            List<AccountItemModel> accountItemModel = accountItemService.queryAccountingSubject("会计分录");
        }
    }

5.CommonService类

public class CommonService {
        public BeanFactory beanFactory;
        public AccountItemService accountItemService;
    
        @Before
        public void setUp(){
            beanFactory = new ClassPathXmlApplicationContext("spring/spring.xml");
            accountItemService = (AccountItemService) beanFactory.getBean("accountItemService");
        }
    }

new ClassPathXmlApplicationContext 说明用的sping容器时appliationContext。

启动测试类成功。

为什么要用单元测试？

直接从测试类开始，不用重新启动项目，高效。我这里配置的是调试service，可以根据项目需求配置不同的common...。

遇到问题

项目中用到了dubbo，但是没有配置好 ，报启动报java.lang.NoClassDefFoundError: org/apache/curator/RetryPolicy问题

添加如下的依赖就好了

<dependency>
                <groupId>org.apache.curator</groupId>
                <artifactId>curator-client</artifactId>
            </dependency>
            <dependency>
                <groupId>org.apache.curator</groupId>
                <artifactId>curator-framework</artifactId>
            </dependency>
