    By default, when an application context is being refreshed, every bean in the context is created and its dependencies are injected. By contrast, when a bean definition is configured to be initialized lazily it will not be created and its dependencies will not be injected until it\u2019s needed.
    \u3002\u3002\u3002<\/p>\n
    In a web application lazy initialization can lead to increased latency for HTTP requests that trigger bean initialization. This will typically just be the first request but it may have an adverse effect on load-balancing and auto-scaling.                                                            <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
