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 extends BaseEntity

}

@Repository
public class MySecondDao extends BaseDao{//SecondEntity extends BaseEntity

}

public class BaseDao{

//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。

看service是不是为null

SpringMVC+Spring Controller自动装配失败

使用SpringMVC+Hibernate+Spring做demo练习,但是启动时报错,说是Controller里依赖的LoginService无法自动装配。 我自己写了个Main类做测试,Dao和Service都是可以自动装配的,唯独Controller不可以,网上看了好多类似的问题,但是也没有解决我的问题,希望哪位高手能帮我解答下,谢谢。 启动时报错: ``` 严重: StandardWrapper.Throwable org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'indexController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.ssg.design.bk.service.LoginService com.ssg.design.bk.controller.IndexController.loginService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.ssg.design.bk.service.LoginService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

Activiti任务监听器调用SSM DAO层

我用jeesite平台想开发一个学生提交作业给老师的工作流,工作流中通过任务监听器动态设置任务执行人(老师)框架是spring +spring mvc+ mybatis + mysql 任务监听器通过实现TaskListener接口的类并通过可视化工具中在老师TASK节点设置了create时调用该类 监听器的代码如下 ``` @Component @Service public class Teacherlisten extends CrudService<StudentToTeacherDao, StudentToT eacher> implements TaskListener{ private String userId; private StudentToTeacher st; private String assignee; private static final long serialVersionUID = 1L; @Override public void notify(DelegateTask delegateTask){ userId = delegateTask.getVariable("apply").toString(); st=dao.findteacher(userId); assignee=st.getTeacher(); delegateTask.setAssignee(assignee); } } ``` 下面为CrudService自动装配DAO的代码 ``` @Transactional(readOnly = true) public abstract class CrudService<D extends CrudDao<T>, T extends DataEntity<T>> extends BaseService { /** * 持久层对象 */ @Autowired protected D dao; ``` 我的设想是通过调用DAO方法访问数据库查询学生对应的老师,然后将执行人设置为该老师,但是遇到的问题是自动装配DAO时 值为NULL,原因可能是监听器与Spring 加载时出问题,已经尝试过很多方法,最后使用JDBC实现的,但是mybatis的框架在这里没用上,希望大神能帮小弟一下,指点一下如何在监听器中能够将Spring与mybatis整合的DAO层引进来。

Mapper不能自动注入?

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.njbd.pm.dao.AdminMapper] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 项目之前是好的,过程中修改了Maven,仓库没报错,按理说不会导致bean的注入,不知道哪里出了问题

Spring 注入为空

在一个SSH的项目中遇到一个问题,我有一个dao的接口BaseJdbcDao,和一个dao的实现类BaseJdbcDaoImpl,实现类已经通过注解提交给容器进行管理,然后有一个工具类MailHelper想通过自动装配载入dao的实现类,可是每次都没有装配成功,代码如下,请教各位: [code="java"] package base; import java.util.List; import java.util.Map;

this.password = password; } protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication (username, password); } } [/code] 然后我在struts的action类中调用MailHelper的send方法进行邮件发送时,打印的dao总是为空,action的代码是: [code="java"] /** * 帐号申请-邮件发送 * @return */ public String sendMail(){ MailHelper mh = new MailHelper(); mh.sendMail(); success = true; return SUCCESS; } [/code] spring的自动扫描和注解配置已经开启,也已经把dao的package路径和MailHelper的package路径加入到基类中了, [code="java"] <context:component-scan base-package="action,service,dao,base,util,tools"/> [/code] 现在就是弄不明白,为什么通过new出来的MailHelper对象中注入的dao总是为空呢。

Spring配置了JDBC后,在使用中jdbcTemplate=null,求大神帮忙,急!急!急!

Spring jdbcTemplate空值异常,如何解决

@Repository public class TestDao { private JdbcTemplate jdbcTemplate; @Autowired public void setDataSource(DataSource dataSource){ this.jdbcTemplate = new JdbcTemplate(dataSource); System.out.println("自动装配"+this.jdbcTemplate.toString()); int i = this.jdbcTemplate.update("UPDATE user set username=? where id=?","小王",1000000002L); System.out.println(i+"行受影响"); } public void update(){ System.out.println("方法中的template"+jdbcTemplate.toString()); int i = this.jdbcTemplate.update("UPDATE user set username=? where id=?","小王",1000000002L); System.out.println(i+"行受影响"); } } ``` ``` 在setDataSource方法中,确实能够看到JdbcTemplate被实例化了,可到了update方法中却是空值,我不知道是什么愿意引起的,头好疼!!!

ssm配置,总是提示说缺少bean,检查了VideoMapper.xml文件,其中并没有重复的id

我用mybatis生成了mapper文件,dao文件,还有bean文件。在调用mapper的时候报错找不到bean,我检查配置文件感觉没有问题,求大佬指点迷津。 ApplicationContext ctx = new ClassPathXmlApplicationContext("/applicationContext.xml"); System.out.println(ctx); 这样是可以获取到的,但是通过ctx获取bean的时候获取不到。 文件的组织结构如下: ![图片说明](https://img-ask.csdn.net/upload/201806/13/1528890525_114253.png) applicationContext.xml : ``` <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> <!-- Spring的配置文件,这里主要配置和业务逻辑有关的 --> <!-- 数据源,事物控制...... --> <context:component-scan base-package="com.teachers.*"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <context:property-placeholder location="classpath:dbConfig.properties"/> <bean id = "pooledDataSource" class = "com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value = "${jdbc.jdbcUrl}"></property> <property name="driverClass" value = "${jdbc.driverClass}"></property> <property name="user" value = "${jdbc.user}"></property> <property name="password" value = "${jdbc.password}"></property> </bean> <!-- ============================================================================================== --> <!-- 配置和myBatis的整合 --> <bean id= "sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定myBatis全局配置文件的位置 --> <property name="configLocation" value = "classpath:mybatis-config.xml"></property> <property name="dataSource" ref = "pooledDataSource"></property> <!-- 指定myBatis mapper文件的位置 --> <property name="mapperLocations" value = "classpath:com.teachers.mappers.*"></property> </bean> <!-- 配置扫描器,将myBatis接口的实现加入到IOC容器中 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 扫描所有的Dao接口的实现,加入到IOC容器中 --> <property name="basePackage" value = "classpath:com.teachers.dao"></property> </bean> <!-- ================================================================================================== --> <!-- 事物控制的配置 --> <bean id = "transactionManager" class ="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 控制住数据源 --> <property name="dataSource" ref="pooledDataSource"></property> </bean> <!-- 开启基于注解的事务,使用xml配置形式的事务(必要主要的都是配置式) --> <aop:config> <!-- 切入点表达式 --> <aop:pointcut expression="execution(* com.teachers.service..*(..))" id="txPoint"/> <!-- 配置事务增强 --> <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/> </aop:config> <!-- 配置事务增强,事务如何切入 --> <tx:advice id = "txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 所有方法都是事务方法 --> <tx:method name="*"/> <!-- 以get开始的所有方法 --> <tx:method name="get*" read-only="true"/> </tx:attributes> </tx:advice> <!-- spring配置文件的核心关注点 1.数据源 2.与myBatis的整合 3.事务控制 --> </beans> ``` Junit测试代码: ``` package com.teachers.test; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.teachers.dao.VideoMapper; /** * 测试Dao层的工作 * @author Xian云 * */ @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations= {"classpath:/applicationContext.xml"}) public class mapperTest { /** * 测试Video */ @Autowired(required=true) VideoMapper video; @Test public void testCRUD() { System.out.println(video); } } ``` 错误信息: ``` org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.teachers.test.mapperTest': Unsatisfied dependency expressed through field 'video'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.teachers.dao.VideoMapper' available: expected at least 1 bean which qualifies as autowire candidate.
