Java静态代码块与spring注解注入的优先级问题

遇到这样一个问题，代码如下：

package com.wonders.stpt.organTree.util;import java.util.HashMap;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.stereotype.Component;import com.wonders.stpt.organTree.service.TorganRelationService;@Component("organTreeUtil")public class OrganTreeUtil {private static HashMap<String,String> receiversMap = null;private static HashMap<String,String> configersMap = null;private static TorganRelationService torganRelationService;public static TorganRelationService getTorganRelationService() {return torganRelationService;}@Autowired(required=false)public void setTorganRelationService(@Qualifier("torganRelationService")TorganRelationService torganRelationService) {OrganTreeUtil.torganRelationService = torganRelationService;}static {init();}public static void init(){if(receiversMap==null){//receiversMap = new HashMap<String, String>();//receiversMap = (HashMap<String, String>) torganRelationService.getReceivers();}if(configersMap==null){//configersMap = new HashMap<String, String>();//configersMap = (HashMap<String, String>) torganRelationService.getConfigers();}}public static HashMap<String,String> getReceiversMap(){synchronized(receiversMap){if(receiversMap==null){receiversMap = (HashMap<String, String>) torganRelationService.getReceivers();}}return receiversMap;}public static HashMap<String,String> getConfigersMap(){synchronized(configersMap){if(configersMap==null){configersMap = (HashMap<String, String>) torganRelationService.getReceivers();}}return configersMap;}public static void refresh(){receiversMap = null;configersMap = null;}}

可以看出，本来想在静态代码块中直接初始化map 的值，但运行后发现spring报空指针，导致不能生成bean，

而报空指针的行数就是 调用service的地方。之后觉得可能是 执行到static块时，spring还未注入。。。

修改后，运行成功。
