springmvc+mybatis调用controller报autowired失败

@service、@controller都写了,@service也写在了实现类而不是接口上,controller中autowired标在了set方法上,单元测试中service和serviceImpl没有问题,但页面调用controller却宝座autowired失败找不到对应service网上找了很多问题我都没有,大概是我检查不够仔细?求大神帮助

添加了一下spring配置和web.xml

异常信息:

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loginController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void controller.LoginController.setLoginService(service.LoginService); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [service.LoginService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

controller

 @Controller("loginController")

@Component

    public LoginService getLoginService() {

    }

    @Autowired
    @Qualifier("loginService")

        User user = loginService.Login(userid, password, perflg);

        if (loginService.Login(userid, password, perflg) != null) {

@Autowired
 private LoginService loginService;
 自动注入我记得不要写set和get方法的,只要在定义变量的时候写个注解就行了

1.检查你的扫描路径是否正确
2.把@component去掉,
3.需要注入的set,get去掉
4.直接用@autowired

spring @Autowired service dao装配顺序?

代码结构如下: @Controller public class MyController{ @Autowired private MyService service; } @Service public class MyService{ @Autowired private MyFirstDao myFirstDao; public void check(Integer id) { //调用baseDao中基本的查询entity的方法 myFirstDao.find(id);//此处myFirstDao==null 为什么?? } } @Repository public class MyFirstDao extends BaseDao<FirstEntity>{//FirstEntity extends BaseEntity } @Repository public class MySecondDao extends BaseDao<SecondEntity>{//SecondEntity extends BaseEntity } public class BaseDao<T extends BaseEntity>{ //实现基本的增删改查 public void find(){} public void del(){} public void add(){} } 按照我的理解,在初始化controller时会自动注入service(即完成service的初始化并获一个实例对象),同时因为service中有用@Autowired标注MyFirstDao ,因此会同时给serivce注入myFirstDao才对,为什么myFirstDao没注入成功呢?获取到的dao为null。 此种场景下,要调用基本的baseDao中的查询方法应该如何解决呢? 注: 其他xml中的配置都没问题。 急求解答。初学者对spring机制不是特别熟悉。

在java timer定时器中调用dao层会报错

现在在做一个web项目,使用spring+springMVC+hibernate框架, 问题描述: 项目中有一个扫描的功能,分即时任务、定时任务、周期任务三种,即时任务已经实现了,现在使用java.util.Timer、java.util.TimerTask类做定时任务,重写TimerTask的run方法,在run方法中调用之前已经没有问题的即时任务扫描方法。每次运行定时任务时,会卡在dao层方法的调用上,因为在即时任务的扫描方法中调用了dao层的数据操作方法,报错“No Session found for current thread”。 即时任务的执行流程:前台提交即时任务扫描请求->控制器调用service层的立即扫描方法startImmediateTask(); 定时任务的执行流程:前台提交定时任务扫描请求->控制器调用service层的定时扫描方法startTimerTask()->调用立即扫描方法startImmediateTask()。 下面附上代码和配置文件,请各位大牛帮忙解决啊! service层代码 ```java /** * 开始定时扫描任务 * @param blTask */ public void startTimerTask(final BLTask blTask) { Date startDate = blTask.getStartTime(); TimerTask task = new TimerTask() { @Override public void run() { // 调用扫描方法 startImmediateTask(blTask); } }; Timer timer = new Timer(); timer.schedule(task, startDate); } /** * 开始即时扫描任务 * @param blTask */ public void startImmediateTask(BLTask blTask) { BLScanParam blScanParam = new BLScanParam(); BLPolicyGroup blPolicyGroup = null; // 策略组 List<BLCheckItem> blCheckItems = null; // 检查项 Map<Long, BLCheckScript> blCheckScriptMap = new HashMap<Long, BLCheckScript>(); // 检查脚本 Long pgId = null; // 策略组ID String alias = null; // 策略别名、检查项别名 Long osType = blTask.getOsType(); // 操作系统类型 List<Long> csIds = new ArrayList<Long>(); // 检查脚本ID数组 blScanParam.setBlTask(blTask); pgId = blTask.getPgId(); // 通过策略组ID查找策略组 blPolicyGroup = blPolicyGroupDao.get(pgId); if (blPolicyGroup == null) { return; } blScanParam.setBlPolicyGroup(blPolicyGroup); alias = blPolicyGroup.getAlias(); // 通过别名、操作系统类别查找所有匹配的检查项 blCheckItems = blCheckItemDao.queryByProerties(new String[]{"alias", "osType"}, new Object[]{alias, osType}); if (blCheckItems == null || blCheckItems.size() <= 0) { return; } blScanParam.setBlCheckItems(blCheckItems); for (BLCheckItem blCheckItem : blCheckItems) { csIds.add(blCheckItem.getCsId()); } int size = csIds.size(); // 获取当前策略组下的所有检查项的检测脚本 List<BLCheckScript> blCheckScripts = blCheckScriptDao.queryByProerties("csId", (Long[])csIds.toArray(new Long[size])); for (BLCheckScript blCheckScript : blCheckScripts) { // 获取当前策略组下的所有检测脚本,并放入map中 blCheckScriptMap.put(blCheckScript.getCsId(), blCheckScript); } blScanParam.setBlCheckScriptMap(blCheckScriptMap); // 分割ip为数组,传入TaskDispatch String[] ips = getIps(blTask.getIpArea()); TaskDispatch taskDispatch = new TaskDispatch(ips, blScanParam); taskDispatch.StartTask(); // 将当前TaskDispatch对象的引用放入taskDispatchMap中,供停止任务时使用 taskDispatchMap.put(blTask.getTkId(), taskDispatch); } ``` BaseDao的部分代码 ```java public class BaseDao<E> implements Dao<E> {

启动springMVC时报错,求大神指导~

配置参数: ![图片说明](https://img-ask.csdn.net/upload/201703/08/1488904727_222077.png) 然后在mybatis-config.xml中 ![图片说明](https://img-ask.csdn.net/upload/201703/08/1488904741_552789.png) 就会报错:Error creating bean with name 'empServiceImpl': Injection of autowired dependencies failed;......Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 如果去掉“<"mapper resource="org/xu/mapping/learnDataMapp.xml"/> ”运行就没错误了; 注:之前只有一个套只操作用户的mapping.xml,mapper.java,servic和serviceimpl,controller可以运行 后面想在写一套操作其他资源的mapping.xml,mapper.java,servic和serviceimpl,controller就运行不了了~~ 在mapper中使用的@Repository 在ServiceImpl类使用 @Autowired调用相应的mapper接口 在controller中使用@Autowired调用相应的service接口 求大神指导,在做毕业设计时,遇到的问题~实在不知道如何解决,,谢谢

Spring Controller的继承,父类注入的属性自类继承为空

@Controller class A { @Autowired protected HttpServletRequest request; } class B extends A{ log.info(request); } 打印为空,debug发现父类的request注入有值,但是在子类获取的时候也变成空了. 为什么? 拜托兄弟们了.
