SpringBoot整合axis1.4后，@Autowired注入失败，使用工具类注入

问题描述：

费劲心思搭建好webservices服务端后，没想到客户端调用失败，查看日志文件，发现报空指针异常，debug代码后，发现sql查询的值都是null。通常情况下，我们将Dao注入Service的时候使用@Autowired注解，但是这里显然没有注入进来。

解决方法：

使用SpringContextUtils工具类注入，首先增加SpringContextUtils.java文件，复制如下内容

 import org.springframework.beans.BeansException;
 import org.springframework.beans.factory.NoSuchBeanDefinitionException;
 import org.springframework.context.ApplicationContext;
 import org.springframework.context.ApplicationContextAware;
 import org.springframework.stereotype.Component;
 /**
  * @author xuchi
  * @Description: @Autowired注入无效，使用此工具类注入
  *
  */
 @Component
 public class SpringContextUtils implements ApplicationContextAware {
     private static ApplicationContext applicationContext = null;

     public SpringContextUtils() {
     }

     public void setApplicationContext(ApplicationContext arg0) throws BeansException {
         if (applicationContext == null) {
             applicationContext = arg0;
         }

     }

     public static ApplicationContext getApplicationContext() {
         return applicationContext;
     }

     public static void setAppCtx(ApplicationContext webAppCtx) {
         if (webAppCtx != null) {
             applicationContext = webAppCtx;
         }
     }

     /**
      * 拿到ApplicationContext对象实例后就可以手动获取Bean的注入实例对象
      */
     public static <T> T getBean(Class<T> clazz) {
         return getApplicationContext().getBean(clazz);
     }

     public static <T> T getBean(String name, Class<T> clazz) throws ClassNotFoundException {
         return getApplicationContext().getBean(name, clazz);
     }

     public static final Object getBean(String beanName) {
         return getApplicationContext().getBean(beanName);
     }

     public static final Object getBean(String beanName, String className) throws ClassNotFoundException {
         Class clz = Class.forName(className);
         return getApplicationContext().getBean(beanName, clz.getClass());
     }

     public static boolean containsBean(String name) {
         return getApplicationContext().containsBean(name);
     }

     public static boolean isSingleton(String name) throws NoSuchBeanDefinitionException {
         return getApplicationContext().isSingleton(name);
     }

     public static Class<?> getType(String name) throws NoSuchBeanDefinitionException {
         return getApplicationContext().getType(name);
     }

     public static String[] getAliases(String name) throws NoSuchBeanDefinitionException {
         return getApplicationContext().getAliases(name);
     }
 }

代替以往的

 @Autowired
 private ManagerDao managerDao;

而使用

 ManagerDao managerDao = SpringContextUtils.getBean(ManagerDao.class);
