使用spring注入时出现is not writable or has an invalid setter method

在web-application-config.xml中定义

     
    
 

 结果，运行时出错：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'employeeServiceDest' defined in ServletContext resource [/WEB-INF/web-application-config.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'esyerDao' of bean class [com.service.EmployeeServiceImpl]:

 Bean property 'esyerDao' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

个人理解spring中的bean标签用来给类创建对象，property相当于类中的属性，如果类要使用属性的话，需要在该类中生成get和set方法，否则会报错。
