春季4 - 对象不会自动装配可变

我有我的JUnit测试类：春季4 - 对象不会自动装配可变

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = { AppConfig.class }) 
@WebAppConfiguration 
public class TelephoneNumberTest { 

@Autowired //Test that bean exists in application context 
private void setPhoneNumberValidator(PhoneNumberValidator phoneNumberValidator){ 
    this.phoneNumberValidator = phoneNumberValidator; 
} 

@Test 
public void autoWireValidatorTest(){ 
    assertNotNull(phoneNumberValidator); //Test passes 

} 

@Test 
public void validUSNumber(){ 
    PhoneNumber phoneNumber = null; 
    ContactType expectedContactType = ContactType.PRIMARY; 
    Country expectedCountry = Country.UNITED_STATES; 
    String expectedAreaCode = "940"; 
    String expectedExchangeCode = "368"; 
    String expectedLocalNumber = "7410"; 

    try { 
     phoneNumber = new TelephoneNumber(expectedContactType, expectedCountry, expectedAreaCode, 
       expectedExchangeCode, expectedLocalNumber); 
    } catch (InvalidPhoneNumberException e) { 
     fail(e.getMessage()); 
    } 

    assertNotNull(phoneNumber); 
    assertThat(phoneNumber.getContactType(), is(expectedContactType)); 
    assertThat(phoneNumber.getCountry(), is(expectedCountry)); 
    assertThat(phoneNumber.getAreaCode(), is(expectedAreaCode)); 
    assertThat(phoneNumber.getExchangeCode(), is(expectedExchangeCode)); 
    assertThat(phoneNumber.getLocalNumber(), is(expectedLocalNumber)); 
} 
}

我的AppConfig

@Configuration 
@EnableWebMvc 
@ComponentScan("software.userprofile") 
public class AppConfig {}

我PhoneNumber对象

package software.userprofile.models; 

import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.beans.factory.annotation.Qualifier; 
import software.userprofile.models.exceptions.InvalidPhoneNumberException; 
import software.userprofile.models.validators.*; 

import java.util.Comparator; 

public class TelephoneNumber implements PhoneNumber{ 
private ContactType contactType; 
private Country country; 
private String areaCode; 
private String exchangeCode; 
private String localNumber; 
private PhoneNumberValidator phoneNumberValidator; 

public TelephoneNumber() {} 

public TelephoneNumber(ContactType contactType, Country country, String areaCode, String exchangeCode, String localNumber) throws InvalidPhoneNumberException { 
    this.contactType = contactType; 
    this.country = country; 
    this.areaCode = areaCode; 
    this.exchangeCode = exchangeCode; 
    this.localNumber = localNumber; 
    validate(); 
} 

public ContactType getType() { 
    return contactType; 
} 

public Country getCountry() { 
    return country; 
} 

public String getAreaCode() { 
    return areaCode; 
} 

public String getExchangeCode(){return exchangeCode;} 

public String getLocalNumber() { 
    return localNumber; 
} 

public PhoneNumberValidator getPhoneNumberValidator(){ 
    return phoneNumberValidator; 
} 

@Autowired 
private void setPhoneNumberValidator(PhoneNumberValidator phoneNumberValidator){ 
    this.phoneNumberValidator = phoneNumberValidator; 
} 

public void validate() throws InvalidPhoneNumberException { 
    phoneNumberValidator.doValidation(country, this); 
} 

@Override 
public String toString() { 
    return "TelephoneNumber{" + 
      "contactType=" + contactType + 
      ", country='" + country + '\'' + 
      ", areaCode='" + areaCode + '\'' + 
      ", exchangeCode='" + exchangeCode + '\'' + 
      ", localNumber='" + localNumber + '\'' + 
      '}'; 
} 

public static Comparator<TelephoneNumber> COMPARE_BY_TYPE = new Comparator<TelephoneNumber>() { 
    public int compare(TelephoneNumber one, TelephoneNumber other) { 
     return one.getType().compareTo(other.getType()); 
    } 
}; 
}

，最后我PhoneNumberValidator类用于

package software.userprofile.models.validators; 

import org.springframework.stereotype.Component; 
import software.userprofile.models.Country; 
import software.userprofile.models.PhoneNumber; 
import software.userprofile.models.exceptions.InvalidPhoneNumberException; 

import java.util.*; 

@Component 
public class PhoneNumberValidator { 
private Map<Country, PhoneNumberCountryValidator> phoneNumberValidators = new HashMap<Country, PhoneNumberCountryValidator>(); 
private Country defaultCountry; 

public PhoneNumberValidator(){ 
    init(); 
} 

private void init(){ 
    phoneNumberValidators.put(Country.UNITED_STATES, new USPhoneNumberCountryValidator()); 
    phoneNumberValidators.put(Country.UNITED_KINGDOM, new UKPhoneNumberValidator()); 
    phoneNumberValidators.put(Country.MEXICO, new MexicoPhoneNumberCountryValidator()); 
    phoneNumberValidators.put(Country.CANADA, new CanadaPhoneNumberValidator()); 
} 

public void doValidation(Country country, PhoneNumber phoneNumber) throws InvalidPhoneNumberException { 
    if(country == null){throw new InvalidPhoneNumberException("Country code is null");} 
    phoneNumberValidators.get(country).validate(phoneNumber); 

} 

public void setPhoneNumberValidators(Map<Country, PhoneNumberCountryValidator> phoneNumberValidators) { 
    this.phoneNumberValidators = phoneNumberValidators; 
}

}

我的问题：在TelephoneNumberClass的PhoneNumberValidator对象不自动装配，当我运行测试，我在PhoneNumberValidator的doValidation（）实例得到一个空指针异常。我能想到的唯一情况是TelephoneNumber类在春天不被识别，但我不知道如何解决这个问题。

我看过网站上的几篇文章，但没有任何工作。

任何想法？

类TelephoneNumber不是由spring管理的，你需要通知spring将其作为bean进行管理。例如。

@Component 
public class TelephoneNumber implements PhoneNumber {...}

我只是试过，但没有运气:(我得到了相同的错误 – jaredramirez

在你的测试类中，你不是注入spring bean而是像这样手动创建一个'PhoneNumber'的实例'phoneNumber = new TelephoneNumber'，因此只需调用'phoneNumber.setPhoneNumberValidator'或注入'phoneNumber' bean即可 – sol4me

您与新创建TelephoneNumber。您应该从applicationContext中获取它（因为原型因此它总是返回一个新的）。或者如果你需要使用新的，那么你可以启用Spring方面和代理。
