Question

将@Service注入@SpringBootTest（Spring Boot 2应用程序的一部分）时，我收到Null指针异常。这是Service类的骨架：

@Service
public class CustomerService {

    public Customer insertCustomer(Customer customer){
        /* Logic here */ 
        return  customer;

    }

}

和Test类：

@SpringBootTest
public class CustomerTest {


   @Autowired
   CustomerService service;

   @Test
    public void testDiscount() {
        Customer customer1 = new Customer("ABC"); 
        service.insertCustomer(customer1);   
        assertEquals(5, customer1.getDiscount());
    }

}

我是否会错过测试类中的任何其他注释才能使其正常工作？谢谢

您应该在测试类级别添加@RunWith(SpringRunner.class)来加载所有必需的bean。还要确保您的软件包名称避免使用@ComponentScan注释。

因此，您可以简单地这样做：

在src / main / java下

package com.customer.service;

@Service
public class CustomerService {

   public Customer insertCustomer(Customer customer) {
        /* Logic here */ 
        return  customer;
   }
}

在src / test / java下

package com.customer.service;

@RunWith(SpringRunner.class)
@SpringBootTest
public class CustomerTest {

   @Autowired
   CustomerService service;

   @Test
   public void testDiscount() {
        Customer customer1 = new Customer("ABC"); 
        service.insertCustomer(customer1);   
        assertEquals(5, customer1.getDiscount());
   }
}

在Spring Boot测试中无法注入@Service
