webService怎麼調用Service

首先需要webService獲取Spring容器中的一個bean
先寫一個工具類用於專門獲取Spring容器中的bean的，代碼如下

/**

package com.elvis.common.utils;

import org.apache.commons.lang3.Validate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Lazy;
import org.springframework.stereotype.Service;


/**
 * 以靜態變量保存Spring ApplicationContext, 可在任何代碼任何地方任何時候取出ApplicaitonContext.
 *
 */
@Service
@Lazy(false)
public class SpringContextHolder implements ApplicationContextAware, DisposableBean {

    private static ApplicationContext applicationContext = null;

    private static Logger logger = LoggerFactory.getLogger(SpringContextHolder.class);

    /**
     * 取得存儲在靜態變量中的ApplicationContext.
     */
    public static ApplicationContext getApplicationContext() {
        assertContextInjected();
        return applicationContext;
    }

    /**
     * 從靜態變量applicationContext中取得Bean, 自動轉型爲所賦值對象的類型.
     */
    @SuppressWarnings("unchecked")
    public static <T> T getBean(String name) {
        assertContextInjected();
        return (T) applicationContext.getBean(name);
    }

    /**
     * 從靜態變量applicationContext中取得Bean, 自動轉型爲所賦值對象的類型.
     */
    public static <T> T getBean(Class<T> requiredType) {
        assertContextInjected();
        return applicationContext.getBean(requiredType);
    }

    /**
     * 清除SpringContextHolder中的ApplicationContext爲Null.
     */
    public static void clearHolder() {
        if (logger.isDebugEnabled()){
            logger.debug("清除SpringContextHolder中的ApplicationContext:" + applicationContext);
        }
        applicationContext = null;
    }

    /**
     * 實現ApplicationContextAware接口, 注入Context到靜態變量中.
     */
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) {
        SpringContextHolder.applicationContext = applicationContext;
    }

    /**
     * 實現DisposableBean接口, 在Context關閉時清理靜態變量.
     */
    @Override
    public void destroy() throws Exception {
        SpringContextHolder.clearHolder();
    }

    /**
     * 檢查ApplicationContext不爲空.
     */
    private static void assertContextInjected() {
        Validate.validState(applicationContext != null, "applicaitonContext屬性未注入, 請在applicationContext.xml中定義SpringContextHolder.");
    }
}

然後要獲取Service時，使用這個類去獲取這個bean，具體代碼如下

//你需要調用的Service
ImoocService imoocService = SpringContextHolder.getApplicationContext().getBean(ImoocService.class);
            imoocService.add(imooc);

這樣webService就可以調用Service了
