我正在尝试为Spock中的控制器编写测试 .
@ContextConfiguration(loader = SpringApplicationContextLoader.class,
classes = [Application.class, CreateUserControllerTest.class])
@WebAppConfiguration
@Configuration
class CreateUserControllerTest extends Specification {
@Autowired
@Qualifier("ble")
PasswordEncryptor passwordEncryptor
@Autowired
UserRepository userRepository
@Autowired
WebApplicationContext context
@Autowired
CreateUserController testedInstance
def "Injection works"() {
expect:
testedInstance instanceof CreateUserController
userRepository != null
}
@Bean
public UserRepository userRepository() {
return Mock(UserRepository.class)
}
@Bean(name = "ble")
PasswordEncryptor passwordEncryptor() {
return Mock(PasswordEncryptor)
}
}
应用程序类只是Spring Boot最简单的配置(启用自动扫描) . 它提供了一个带PasswordEncryptor . 我想用我的bean替换这个bean来提供一个模拟 .
但不幸的是Spring抛出NoUniqueBeanDefinitionException:
Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [org.jasypt.util.password.PasswordEncryptor] is defined: expected single matching bean but found 2: provide,ble

@Qualifier注释似乎根本不起作用 . 我能做什么?
Edit
问题不在 CreateUserControllerTest
中,而在 CreateUserController
中 .
public class CreateUserController {
@Autowired
private PasswordEncryptor encryptor;
}
没有 @Qualifier
注释,因此Spring不知道如何使Spring通过本地配置从Application替换 PasswordEncryptor
bean .

@Qualifier
用于连接bean的特定实例,如果您有多个相同接口的实现 .但是你仍然需要在spring上下文中为每个bean提供一个'UNIQUE'名称 .
所以你试图注册两个名为'
passwordEncryptor
'. One in your test, and it seems the other one is in your actual code 'Application.class
'的bean .如果要模拟'PasswordEncryptor',请使用
@Mock
或@Spy
. (或)如果要避免错误,请更改方法的名称以避免实例名称冲突 .Edit
该错误的另一种可能性是在代码中为某个地方定义
@Autowired
为'passwordEncryptor
'而没有@Qualifier
标记,但
你有两个
@Bean(name="...") passwordEncryptor
定义的实例,所以Spring上下文很困惑,选择哪一个'Auto Wire'字段 .
