Spring @Autowired在@WebService类中不起作用，但在Junit测试类中起作用

Question

[EDIT]：我使用this post

的第二个解决方案解决了我的问题

我创建了一个WebApplicationContextLocator类：

@Configuration
public class WebApplicationContextLocator implements ServletContextInitializer {

    private static WebApplicationContext webApplicationContext;

    public static WebApplicationContext getCurrentWebApplicationContext() {
        return webApplicationContext;
    }

    @Override
    public void onStartup( ServletContext servletContext) throws ServletException {
        webApplicationContext = WebApplicationContextUtils.getWebApplicationContext(servletContext);
    }
}

然后我如下修改了SearchBookWebServiceImpl：

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor;
import org.springframework.beans.factory.support.DefaultListableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.stereotype.Service;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.SpringBeanAutowiringSupport;
import org.thibaut.thelibrary.webservice.configuration.WebApplicationContextLocator;

import javax.annotation.PostConstruct;
import javax.jws.WebMethod;
import javax.jws.WebService;


@Service
@Slf4j
@WebService(serviceName = "SearchBookService", portName = "SearchBookPort",
        targetNamespace = "http://thelibrary.service.ws/",
        endpointInterface = "org.thibaut.thelibrary.webservice.webservice.SearchBookWebService")
public class SearchBookWebServiceImpl extends AbstractWebService implements SearchBookWebService{

    @Override
    @WebMethod
    public String getBookTitle( Integer id ){
        return getServiceFactory().getBookService().getBookTitle( id );
    }

    public SearchBookWebServiceImpl() {
        AutowiredAnnotationBeanPostProcessor bpp = new AutowiredAnnotationBeanPostProcessor();
        WebApplicationContext currentContext = WebApplicationContextLocator.getCurrentWebApplicationContext();
        bpp.setBeanFactory(currentContext.getAutowireCapableBeanFactory());
        bpp.processInjection(this);
    }

    // alternative constructor to facilitate unit testing.
    protected SearchBookWebServiceImpl( ApplicationContext context) {
        AutowiredAnnotationBeanPostProcessor bpp = new AutowiredAnnotationBeanPostProcessor();
        bpp.setBeanFactory(new DefaultListableBeanFactory(context));
        bpp.processInjection(this);
    }

}

我只是不知道如何将我的问题标记为已回答，因为我无法标记任何答案...

我正在使用以下程序开发一个多模块应用程序：WebService，Springboot，Hibernate，Spring-data。我正在尝试使用自下而上的方法测试一个非常简单的Web服务（首先是类，然后自动生成wsdl文件）。

Spring注释@Autowired在我的小@WebService类中不起作用。因此，我无法从@WebService类访问@WebMethod中的spring bean。但是@Autowired在我用来测试@WebMethod的Junit测试类中可以正常工作。另外，WebService本身也是可访问的。我使用不需要任何bean的WebMethod进行了测试，并且可以正常工作。

[EDIT]：我刚刚发现了这篇文章Spring Boot register JAX-WS webservice as bean 我尝试了不同的解决方案，正确地理解了它们。但是，它解决了铅的问题。请参阅下面的我的Springboot应用程序（来自上面帖子的最后一个解决方案）。

我将此帖子设为红色：Why is my Spring @Autowired field null?。但这并不能影响我的铅含量。 （我没有使用“ new myObject（）”代替Spring上下文，而且我的pb似乎更多地是关于“ javax.jws.WebService”注释类，而不是“ org.springframework.stereotype.Service”注释类） 我试图用XML声明我的bean，但是它没有任何改变。

我的@SpringbootApplication类：

import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.thibaut.thelibrary.webservice.webservice.SearchBookWebService;
import org.thibaut.thelibrary.webservice.webservice.SearchBookWebServiceImpl;

import javax.xml.ws.Endpoint;

@SpringBootApplication
@ComponentScan(basePackages = {"org.thibaut.thelibrary"})
@EnableJpaRepositories(basePackages = {"org.thibaut.thelibrary"})
@EntityScan(basePackages = {"org.thibaut.thelibrary"})
public class Application {

    public static void main(String[] args) {

        SpringApplication.run( Application.class, args );

    }

    @Bean
    public ServletRegistrationBean dispatcherServlet() {
        return new ServletRegistrationBean(new CXFServlet(), "/soap-api/*");
    }

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus() {
        return new SpringBus();
    }

    @Bean
    public SearchBookWebService searchBookWebService() {
        return new SearchBookWebServiceImpl();
    }

    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint = new EndpointImpl(springBus(), searchBookWebService());
        endpoint.publish("/SearchBookWebService");
        return endpoint;
    }
}

我的@WebService实现类

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

import javax.jws.WebMethod;
import javax.jws.WebService;

@Service
@Slf4j
@WebService(serviceName = "SearchBookService", portName = "SearchBookPort",
targetNamespace = "http://thelibrary.service.ws/",
endpointInterface = "org.thibaut.thelibrary.webservice.webservice.SearchBookWebService")
public class SearchBookWebServiceImpl extends AbstractWebService implements     SearchBookWebService{

    @Override
    @WebMethod
    public String getBookTitle( Integer id ){
        return getServiceFactory().getBookService().getBookTitle( id );
    }

}

我的@WebService接口

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService(targetNamespace = "http://thelibrary.service.ws/", name = "SearchBook")
public interface SearchBookWebService {

    @WebMethod
    abstract String getBookTitle( Integer id );

}

AbstractWebService类

@Service
public abstract class AbstractWebService {

    private ServiceFactory serviceFactory;

    ServiceFactory getServiceFactory( ) {
        return serviceFactory;
    }

    @Autowired
    public void setServiceFactory( ServiceFactory serviceFactory ) {
        this.serviceFactory = serviceFactory;
    }
}

ServiceFactory实现类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.thibaut.thelibrary.service.contract.BookService;
import org.thibaut.thelibrary.service.contract.ServiceFactory;

@Component
public class ServiceFactoryImpl implements ServiceFactory {

    private BookService bookService;    

    @Override
    public BookService getBookService( ) {
        return bookService;
    }

    @Override
    @Autowired
    public void setBookService( BookService bookService ) {
        this.bookService = bookService;
    }
}

ServiceFactory接口：

public interface ServiceFactory {

    BookService getBookService( );

    void setBookService( BookService bookService );
}

RepositoryFactoryImpl类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;
import org.thibaut.thelibrary.repository.contract.RepositoryFactory;

@Component
public class RepositoryFactoryImpl implements RepositoryFactory {

    private BookRepository bookRepository;

    @Override
    public BookRepository getBookRepository( ) {
        return bookRepository;
    }

    @Override
    @Autowired
    public void setBookRepository( BookRepository bookRepository ) {
        this.bookRepository = bookRepository;
    }
}

BookRepository界面：

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.querydsl.QuerydslPredicateExecutor;
import org.springframework.stereotype.Repository;
import org.thibaut.thelibrary.domain.entity.Book;

@Repository
public interface BookRepository extends JpaRepository< Book, Integer >, 
QuerydslPredicateExecutor<Book> {
}

当我在Glassfish5中部署WebService战争时，我尝试测试getBookTitle（）Web方法时，我遇到了NullPointerException，因为在我的AbstractWebService类中，serviceFactory bean为Null（知道这要归功于调试模式）。 我使用网址测试了该方法 http://desktop-11dqe2u.local:8080/thelibrary-webservice/SearchBookService?Tester 并且也通过SoapUi。 结果是一样的。

错误是：
