如何让 @WebService spring 感知

Question

我有一个 Web 服务，我正在尝试将变量自动装配到其中。以下是该类：

package com.xetius.isales.pr7.service;

import java.util.Arrays;
import java.util.List;

import javax.jws.WebService;

import org.springframework.beans.factory.annotation.Autowired;

import com.xetius.isales.pr7.domain.PR7Product;
import com.xetius.isales.pr7.domain.PR7Upgrade;
import com.xetius.isales.pr7.logic.UpgradeControllerInterface;

@WebService(serviceName="ProductRulesService",
            portName="ProductRulesPort",
            endpointInterface="com.xetius.isales.pr7.service.ProductRulesWebService",
            targetNamespace="http://pr7.isales.xetius.com")
public class ProductRulesWebService implements ProductRulesWebServiceInterface {

    @Autowired
    private UpgradeControllerInterface upgradeController;

    @Override
    public List<PR7Product> getProducts() {
        if (upgradeController == null) {
            return Arrays.asList(new PR7Product("Fail"));
        }
        return upgradeController.getProducts();
    }

    @Override
    public List<PR7Upgrade> getUpgrades() {
        if (upgradeController == null) {
            return Arrays.asList(new PR7Upgrade("Fail"));
        }
        return upgradeController.getUpgrades();
    }

    @Override
    public List<PR7Product> getProductsForUpgradeWithName(String upgradeName) {
        if (upgradeController == null) {
            return Arrays.asList(new PR7Product("Fail"));
        }
        return getProductsForUpgradeWithName(upgradeName);
    }

}

但是，当我尝试访问 Web 服务时，我收到返回的失败版本，这意味着upgradeController 没有被自动连接。这是我的 applicationContext：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    <context:component-scan base-package="com.xetius.isales.pr7" />
    <context:annotation-config />

    <bean id="upgradeController" class="com.xetius.isales.pr7.logic.UpgradeController" />

</beans>

如何使 @WebService 类能够感知 Spring 并进行自动装配

Answer 1

如果您希望自动装配，ProductRulesWebService 需要扩展 SpringBeanAutowiringSupport

扩展该类将允许 UpgradeController 自动装配

Answer 2

使用像 CXF 这样的堆栈，它原生支持 Spring，那么你基本上可以做这样的事情：

<bean id="aService" class="com.xetius.isales.pr7.service.ProductRulesWebService " />

<jaxws:endpoint id="aServiceEndpoint" implementor="#aService" address="/aService" />

Answer 3

根据容器版本甚至 Spring，您将有一个简单的解决方案来公开 WSDL，使用：

@PostConstruct
SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
