spring-mybatis找不到sqlsessionfactoryBean这个类

各位,我用maven管理项目,在pom.xml配置中导入了mybatis-spring 1.3.0.jar,图片说明

然后在spring-mybatis.xml中配置了SqlSessionFactoryBean如下图:图片说明,

在任何类中使用sqlsessionFactoryBean这个类时eclipse不提示此类,如下图:图片说明

当将类名输入完整后,再按Ctrl+1时又会有此类提示,如下图图片说明

当用Junit测试时,如下图图片说明

抛出classnotfindException: org.mybatis.spring.SqlSessionFactoryBean异常,异常信息如下:

不是在maven中配置好SqlSessionFactoryBean就行吗?同学,你这个先导入,然后再配置的做法让我很迷茫

游语 回复bianguan1990: 我也遇到过这种情况,因为有时候我们下载到的maven包本身可能在下载过程中出了错,你可以试着下载更低版本的包,也可以试试重新下载,当然最粗暴的方式是找一个没有问题的包,直接加进去,然后重新导包

本来已经整合了spring和springmvc,然后我再添加了mybatis的依赖,数据库的配置等等。在test类里mybatis可以单独运作。但是和spring整合的时候就出现问题. 这是我的目录结构 ![图片说明](https://img-ask.csdn.net/upload/202002/11/1581431166_377484.png) 我的dao中的类如下 ``` @Repository public interface IAccountDao { @Select("select * from account") List<Account> findAll(); @Insert("insert into account(name,money) values (#{name},#{money})") void saveAccount(Account account); } ``` service中的类如下 ``` @Service("accountService") public class AccountServiceImpl implements IAccountService { @Autowired private IAccountDao accountDao; @Override public List<Account> findAll() { System.out.println("findAll_service"); return accountDao.findAll(); } @Override public void saveAccount(Account account) { System.out.println("saveAccount_service"); accountDao.saveAccount(account); } } ``` 而且我的spring的配置文件已经按照教程中那样引入了mybatis的工厂什么的 ``` <?xml version="1.0" encoding="UTF-8"?> <beans 一堆约束省略了> <context:component-scan base-package="com.HSY"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!-- 整合Mybatis--> <!-- 配置C3P0的连接池对象 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/ssm" /> <property name="username" value="root" /> <property name="password" value="123456" /> </bean> <!-- 配置SqlSession的工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置扫描dao的包--> <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.HSY.dao"/> </bean> </beans> ``` SqlMapConfig的数据库配置也配了,但是最后仍然报错 ``` beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.HSY.dao.IAccountDao' available: expected at least 1 bean which qualifies as autowire candidate.

ssm项目的问题 Servlet.init() for servlet [spring-dispatcher] threw exception
跟着网上的ssm项目做,可以说代码基本都是照着敲的。但是还是会有各种各样的bug。这个问题困扰我两天了,网上常见的我都试过,包括spring和jdk版本的适配,jar包的调整等等。请各位大佬帮忙看一下,感激不尽!下面是我警告和错误的代码: ``` WARN org.springframework.web.context.support.XmlWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in file [D:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\o2o\WEB-INF\classes\spring\spring-dao.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse mapping resource: 'file [D:\Program Files\Apache Software Foundation\Tomcat 9.0\webapps\o2o\WEB-INF\classes\mapper\AreaDao.xml]'; nested exception is org.apache.ibatis.builder.BuilderException: Error parsing Mapper XML.

使用SSM框架配置式开发(不用注解),为何Service中无法注入Dao?
我用Intellij Idea开发的,所以配置文件中出错会标识红色,spring-service.xml中的ref="IStudentDao"部分出错。 另外我用Maven做的项目管理,不知道是不是配置文件放置的路径有问题。附上我的项目目录结构:![图片说明](https://img-ask.csdn.net/upload/201704/17/1492434652_95958.png) 部署到Tomcat上启动后,报No adapter for handler [com.bruceliao.controller.StudentController@12bc3bf8]: The DispatcherServlet configuration needs to include a HandlerAdapter that supports this handler Mybatis配置文件: ``` <configuration> <!--别名--> <typeAliases> <package name="com.bruceliao.beans"/> </typeAliases> <!--Mapper的位置--> <mappers> <package name="com.bruceliao.dao"/> </mappers> </configuration> ``` Spring配置文件: spring-mybatis.xml ``` <!--注册sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="configLocation" value="classpath:mybatis.xml"/> <property name="dataSource" ref="dataSource"/> </bean> <!--生成Dao代理对象--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> <property name="basePackage" value="com.bruceliao.dao"/> </bean> ``` spring-service.xml ``` <!--注册Service--> <bean id="studentService" class="com.bruceliao.service.impl.StudentServiceImpl"> <property name="studentDao" ref="IStudentDao"/> </bean> ``` spring-mvc.xml ``` <bean id="/view/login.do" class="com.bruceliao.controller.StudentController"> <property name="studentService" ref="studentService"/> </bean> ``` ![图片说明](https://img-ask.csdn.net/upload/201704/17/1492435263_528738.png)

使用spring+mybatis写了一个jar程序,打包后xml配置中properties无法解析
使用spring+mybatis写了一个jar程序,打包的时候将properties放在了jar包外面,现在applicationContext.xml可以读取到,但是读取不到数据库配置的properties文件 ``` <context:property-placeholder location="classpath:db.properties"/> <context:component-scan base-package="com.test.service.impl"></context:component-scan> <bean class="org.springframework.jdbc.datasource.DriverManagerDataSource" id="dataSource"> <property name="driverClassName" value="${oracle.driverClassName}"></property> <property name="url" value="${oracle.url}"></property> <property name="username" value="${oracle.username}"></property> <property name="password" value="${oracle.password}"></property> </bean> <bean class="org.mybatis.spring.SqlSessionFactoryBean" id="factory"> <property name="dataSource" ref="dataSource"></property> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" id="mapper"> <property name="basePackage" value="com.jl.batchregister.mapper"></property> <property name="sqlSessionFactoryBeanName" value="factory"></property> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> ``` 如果将classpath改为classpath*之后可以读取到文件,但是${}占位符直接按字符串加载了,这种问题该怎么解决
