Old 1.x 'singleton' attribute in use - upgrade to 'scope' declaration

[Raymond Chiu Wing Hing]

Dear all,

I upgrade the web project from JDK 1.5 to JDK 1.7.
It show some compile errors as below:
Old 1.x 'singleton' attribute in use - upgrade to 'scope' declaration

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
	<bean id="config" class="hk.com.xxxx.sms.dao.ConfigDAOImpl" singleton="false">

I searched in the web and find https://stackoverflow.com/questions/28262225/configuration-issue-during-spring-upgrade.
But it said scope="singleton". But in my case, it is false.
what should be scope="xxxxx"?
or ignore it??

Please help

Here's a list of available bean scopes: https://docs.spring.io/spring/docs/5.0.1.RELEASE/spring-framework-reference/core.html#beans-factory-scopes

You have to select the one that matches your use case. If it's not singleton, then most of the time it's request.

Singleton is the default scope, the alternative would be a prototype.   The others are really for web-based application development.

Here's some old documentation showing how it used to be done in XML --> Spring Bean Scope
