使用@autowired將會話bean注入到Web服務端點

Question

我在嘗試將會話作用域bean注入到Web服務端點時遇到了一些麻煩。當我將範圍更改爲默認值時，它可以正常工作。是否有任何我應該定義的進一步配置？

Web服務類：

@WebService(endpointInterface = "com.app.webservice.endpoint.MainIntegratorEndpoint") 
public class MainIntegratorEndpointImpl extends SpringBeanAutowiringSupport implements MainIntegratorEndpoint { 

    private final Logger logger = Logger.getLogger(this.getClass()); 

    @Autowired 
    private TesteService testeService; 

    @Override 
    @WebMethod(operationName = "sendDataXml") 
    public String sendDataXml(@WebParam(name = "xml") final String xml) { 
     return ""; 
    } 

} 

會話Bean：

@Service 
@Scope(value=WebApplicationContext.SCOPE_SESSION) 
public class TesteService { 

} 

爲spring-servlet.xml：

<beans ...> 

    <context:component-scan base-package="com" /> 

    <mvc:annotation-driven /> 

    <bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder" /> 

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> 
     <property name="prefix" value="/WEB-INF/views/" /> 
     <property name="suffix" value=".jsp" /> 
    </bean> 

    <mvc:resources mapping="/resources/**" location="/resources/" 
     cache-period="31556926" /> 

    <tx:annotation-driven /> 


    <wss:binding url="/mainEndpoint"> 

    <wss:service> 
    <ws:service bean="#mainIntegratorEndpoint" /> 
    </wss:service> 
    </wss:binding> 

    <bean id="mainIntegratorEndpoint" class="com.app.webservice.endpoint.impl.MainIntegratorEndpointImpl" 
     /> 

</beans> 

最後，我讓我的控制檯上出現以下錯誤：

Answer 1

你需要告訴春天創建一個代理，如果你想注入一個會話範圍的bean到一個單例的bean（你的web服務）：

@Scope(value=WebApplicationContext.SCOPE_SESSION, proxyMode = ScopedProxyMode.TARGET_CLASS) 
public class TesteService { 
... 
}
