老师，不好意思，再麻烦你一下

Question

十月 01, 2017 12:37:51 上午 org.springframework.web.context.ContextLoader initWebApplicationContext

严重: Context initialization failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userManageController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mmall.service.IUserService com.mmall.controller.backend.UserManageController.iUserService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'iUserService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mmall.dao.UserMapper com.mmall.service.impl.UserServiceImpl.userMapper; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [C:\Users\LIURUN\IdeaProjects\mmall\target\mmall\WEB-INF\classes\com\mmall\dao\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory': : Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext-datasource.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [applicationContext-datasource.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'int' for property 'initialSize'; nested exception is java.lang.NumberFormatException: For input string: "${db.initialSize}"; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [applicationContext-datasource.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [applicationContext-datasource.xml]: Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException: Failed to convert property value of type 'java.lang.String' to required type 'int' for property 'initialSize'; nested exception is java.lang.NumberFormatException: For input string: "${db.initialSize}"

最后一句话说是字符转换异常，那该怎么办么？  已经让这个问题困扰好几个消失了    祝老师国庆快乐
