Error creating bean with name 'categoryController
如果使用的是注解 那么
问题是在Service层的实现类中没有追加:
@Service("XXXXX")

qq_35649402
你们让我起个名啊 @Service("categoryService") public class CategoryServiceImpl implements CategoryService 我写了啊

com.how2java.mapper.CategoryMapper
没找到这个

楼上说的是实体类。。。。。。。

@Service("categoryService") CategoryService

qq_35649402
你们让我起个名啊 是加在CategoryService上而不是CategoryServiceImpl上?
2 年多之前 回复

@RequestMapping路径没找到

我也来猜一下,报的错误是Error creating bean with name 'categoryController': Injection of autowired dependencies failed;,说明依赖注入找不到这个bean。然后看了一下楼主的配置,用的是注解形式。能找到你的controller但是找不到service,问题出在路径配置。

expression="org.springframework.stereotype.Controller"/>
你这这里定义的是自动扫描com.how2java.controller下的注解,不过你的service并不在这个路径下,所以报错了。可以改成com.how2java这个上级路径。不知道能否解决楼主问题

你的 applicationContext.xml 文件上没有加入包扫描, 没有扫描Service

应该是没有扫描service,试试呢

com.how2java.mapper.CategoryMapper怎么没贴出来? 报的错提示语这个类有关!!!!

SpringMVC注入失败

Spring与Springmvc注解问题
Spring中配置是这样的 context:component-scan base-package="cn.ji.*"/ 如果SPRINGmvc的配置文件在写 context:component-scan base-package="cn.ji.controller"/ 或者 context:component-scan base-package="cn.ji.*"/ 所有的依赖注入就会失败报错 如果不在Springmvc中配置启动起来不报错但是访问不到controller,请问配置文件哪里写错了应该怎么写 之前普通的javaweb项目 两个XML都有context:component-scan base-package是没有问题的 现在弄成maven项目了 就出现了这个问题 还是我少了什么JAR包嘛 附上JAR包图![图片说明](https://img-ask.csdn.net/upload/201701/30/1485719156_993940.png)

springmvc:为什么单元测试却能正常注入service并运行,controller却注入service失败?
这是单元测试 ``` @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:applicationContext.xml") public class mvc { //@Resource(name="itemServiceMapper") @Autowired private ItemService ItemService; @Test public void testmapper(){ System.out.println(ItemService.getItemList()); } } ``` 这是单元测试的运行结果, ![图片说明](https://img-ask.csdn.net/upload/201903/11/1552271903_27196.png) 但是我在controller里注入却报错... ``` @Controller public class ItemController { //@Resource(name="ItemServiceMapper") @Autowired private ItemService ItemService; @RequestMapping("itemList") public ModelAndView showItemList() { ModelAndView mv=new ModelAndView(); List<Item> list = ItemService.getItemList(); mv.addObject("itemList", list); mv.setViewName("itemList"); return mv; } ``` 报错 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'itemController': Unsatisfied dependency expressed through field 'ItemService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'service.ItemService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 讲道理单元测试都成功了,那些配置应该没有错才对啊... @Service注解也加了,Controller,ServiceImpl包也扫描了...
Springmvc在线程池中无法使用Service
问题:我在项目中使用线程池新建了线程列队,controller请求后把耗时任务交给列队处理, 列队中需要service注入,但是在Test中测,子线程无法使用service的方法,代码如下: TaskQueueHandler.java ``` public interface TaskQueueHandler { String getTaskName(); int doInvoke(); } ``` TaskSerialQueueService.java ... ``` @PostConstruct public void init(){ serviceThreadStatus=service.submit(new Thread(new Runnable() { @Override public void run() { while (running){ try{ TaskQueueHandler taskQueueHandler= tasks.take(); if(taskQueueHandler!=null){ try{ taskQueueHandler.doInvoke(); }catch (Exception e){ log.error(taskQueueHandler.getTaskName()+" doInvoke Error!",e.getCause()); } } }catch (InterruptedException e){ running=false; } } } })); } /** * 往列队中添加新任务 * @param taskQueueHandler * @return */ public synchronized boolean addTask(TaskQueueHandler taskQueueHandler){ if(!checkServiceIsActive()){ activeService(); } boolean success= tasks.offer(taskQueueHandler); if(!success){ log.warn(taskQueueHandler.getTaskName()+"任务列队添加失败!"); } return success; } ``` ... WxPayNotifyTask.java ``` public class WxPayNotifyTask implements TaskQueueHandler{ private String orderNo; public WxPayNotifyTask(String mOrderNo){ this.orderNo=mOrderNo; } @Override public String getTaskName() { return WxPayNotifyTask.class.getSimpleName(); } private OrderService orderService; @Override public int doInvoke() { System.out.println("orderNo="+orderNo); orderService= (OrderService)SpringUtils.getBean("orderService"); try{ OrderBean orderBean=orderService.queryByOrderNo(orderNo); System.out.println(orderBean.toString()); }catch (Exception e){ e.printStackTrace(); } return 0; } } ``` 测试代码中调用 ``` @Autowired private TaskSerialQueueService taskQueueService; taskQueueService.addTask(new WxPayNotifyTask("379991638464417792")); ``` 测试发现报错信息如下 ``` org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLException: interrupt at org.springframework.jdbc.datasource.DataSourceTransactionManager.doBegin(DataSourceTransactionManager.java:289) at org.springframework.transaction.support.AbstractPlatformTransactionManager.getTransaction(AbstractPlatformTransactionManager.java:377) at org.springframework.transaction.interceptor.TransactionAspectSupport.createTransactionIfNecessary(TransactionAspectSupport.java:461) at org.springframework.transaction.interceptor.TransactionAspectSupport.invokeWithinTransaction(TransactionAspectSupport.java:277) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:96) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.interceptor.ExposeInvocationInterceptor.invoke(ExposeInvocationInterceptor.java:92) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:179) at org.springframework.aop.framework.CglibAopProxy$DynamicAdvisedInterceptor.intercept(CglibAopProxy.java:673) at com.superior.chalk.service.order.OrderServiceImpl$$EnhancerBySpringCGLIB$$d45a5b10.queryByOrderNo(<generated>) at com.superior.chalk.task.WxPayNotifyTask.doInvoke(WxPayNotifyTask.java:27) at com.superior.chalk.task.queue.TaskSerialQueueService$1.run(TaskSerialQueueService.java:35) at java.lang.Thread.run(Thread.java:745) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.sql.SQLException: interrupt ``` 最后发现如直接在test中使用 new WxPayNotifyTask("379991638464417792").invoke()是可以使用service的,但是在子线程中能获取到service但调用service的方法就报错。 先谢谢各位大佬帮忙分析分析!

SSM Dubbo 集成 Shiro 自定义Realm 注入 SysUserMapper 失败
先说下大概框架 SpringMVC Spring Mybatis 集成Dubbo,现在引入 shiro 服务端 配置 spring-mybatis.xml spring-service.xml 文件 消费端 配置 spring-mvc.xml 文件 当前 shiro.xml 配置文件 配置在了 消费端 。(服务端 ,消费端 都配置过 ,配置在服务端 ,页面拦截失效)。 spring-service.xml : ``` <context:component-scan base-package="com.artmall.manager.service"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` spring-mvc.xml : ``` <!-- 扫描带注解的包 --> <context:component-scan base-package="com.artmall.manager"> <context:include-filter type="aspectj" expression="com.artmall.manager.common.aspect"/> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` # 出现问题: 自定义 Realm 的时候 引入 SysUserMapper , 服务端启动的时候 报错,Error creating bean with name 'userRealm': Could not autowire field :SysUserMapper。也就是说 SysUserMapper 注入是失败的 。 ** 理解**: shiro的自定义realm的认证阶段属于filter,当时的spring bean还没有读取进来。 见上配置文件 **服务端** 在启动的时候就已经 扫描 service了。 疑问的是 消费端 再启动的时候为什么 还会报这样的错。不知道是我理解的还不够到位还是什么 配置上有问题 希望有知道的朋友多多指点下 非常感谢。
