 Some devices and apps use insecure sign-in technology to access your data.
Choosing Disable prevents these less secure devices and apps from accessing your Google Account.
Choosing Enable increases your chances of unauthorized account access but allows you to continue using these less secure devices and apps. Learn more

Access for less secure apps should be enabled

Exceptions in java

Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mailService' defined in ServletContext resource [/WEB-INF/landview-mail.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'mailSender' of bean class [com.mapview.landview.service.impl.MailServiceImpl]: Bean property 'mailSender' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

solution : you have forget to create getter and setter method in java class for id specified in xml as bean.
