如何在SpringData JPA中不使用ApplicationContext或ClassPathXmlApplicationContext来加载bean

我刚接触Spring Data JPA。我在加载bean时遇到问题而没有使用ApplicationContext或ClassPathXmlApplicationContext。因为在我当前的项目中我有一个旧的spring相关的jar无法删除。因为我当前的＆＃34; SpringContext .XML＆＃34;无法加载。这是我的代码阻止加载SpringContext.xml 

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("SpringContext.xml");
RegistrationBean registrationBean = (RegistrationBean)context.getBean("registrationBean");

这是我的Repository

的RegistrationBean 
@Component
public class RegistrationBean {
@Autowired
private CreditorProfileRepository creditorProfileReposigtory;

public RegistrationBean(){

}
public CreditorProfileRepository getCreditorProfileReposigtory() {
    return creditorProfileReposigtory;
}
public void setEmployeeReposigtory(CreditorProfileRepository creditorProfileReposigtory) {
    this.creditorProfileReposigtory = creditorProfileReposigtory;
}

}

这是我的存储库

import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
@Repository
public interface CreditorProfileRepository extends CrudRepository <CreditorProfile, String>{
public CreditorProfile  findBympcreditorprofileidpk(String  mpcreditorprofileidpk);
}

所以我教过使用构造函数注入来在我的应用程序类中加载registrationBean。这是我的应用程序类

public class CreateCreditorProfile implements ICreateCreditorProfile{

RegistrationBean repositoryRegistration;

CreateCreditorProfile(RegistrationBean repositoryRegistration){
    this.repositoryRegistration=repositoryRegistration;
}

CreateCreditorProfile(){
    this.repositoryRegistration=repositoryRegistration;
}
@Override
public void createCreditorProfile(CreditorProfileServiceDetails creditorProfileServiceDetails) {
            CreditorProfile creditorProfile = new CreditorProfile();
            creditorProfile.setcreditorprofileidpk("343243243");
            creditorProfile.setpartyid("000005");
            creditorProfile.setpartyname("Federico o Peluso");

            repositoryRegistration.getCreditorProfileReposigtory().save(creditorProfile);
}

这是我的ApplicationContext.xml 

<bean id="registrationBean" class="com.mi.bn.payment.persistence.RegistrationBean" scope="prototype" />
<bean id="CreateCreditorProfile" class="com.mi.bn.paymen.persistence.CreateCreditorProfile" scope="prototype" >
    <constructor-arg name="repositoryRegistration" ref="registrationBean" />
</bean>
<bean id="creditorsProfileConfiguration" class="com.mi.bn.payment.domain.configuration.CreditorsProfileConfiguration" scope="prototype">
    <constructor-arg name="creater" ref="CreateCreditorProfile" />
</bean>

这是我的SpringContext.xml

但仍然是我的应用程序类我在

得到空指针异常
  

repositoryRegistration.getCreditorProfileReposigtory（）。保存（creditorprofile）

所以，请让我知道解决此问题的方法。

这是堆栈跟踪

答案 0 :(得分：0)

您的RegistrationBean似乎不是自动装配的：

public class CreateCreditorProfile implements ICreateCreditorProfile{
     @Autowired
     RegistrationBean repositoryRegistration;
...
}

关于你的问题，为什么构造函数调用不起作用，据我所知，有2个context.xml声明--ApplicationContext.xml和SpringContext.xml。你需要加载它们：

ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
  "SpringContext.xml","ApplicationContext.xml");

或者您可以在SpringContext.xml

中导入Application.xml 
<import resource="ApplicationContext.xml" />

两种方式都应该导致正确加载bean。
