SSM中进行Junit单元测试时无法注入service

场景

在SSM项目中进行Junit单元测试时调用外部的service时，在使用时打断点发现为空。

代码如下：

public class AlipayTester {
 
 private PassOrderService passOrderService;
 @Autowired
 public void setPassOrderService(PassOrderService passOrderService) {
  this.passOrderService = passOrderService;
 }

 @Test
 public void alipay() {
  
  try {
   
   PassOrder passOrder = passOrderService.getByPrimaryKey("89387");
   
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

 }
}

然后会提示passOrderService为空。

解决

添加注解：

@RunWith(SpringJUnit4ClassRunner.class)
//告诉junit spring配置文件
@ContextConfiguration("classpath:spring.xml")

 

添加后代码：

@RunWith(SpringJUnit4ClassRunner.class)
//告诉junit spring配置文件
@ContextConfiguration("classpath:spring.xml")
public class AlipayTester {
 
 private PassOrderService passOrderService;
 @Autowired
 public void setPassOrderService(PassOrderService passOrderService) {
  this.passOrderService = passOrderService;
 }

 @Test
 public void alipay() {
  
  try {
   
   PassOrder passOrder = passOrderService.getByPrimaryKey("89387");
   
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

 }
}
