Looking at my web application, it looks like the default autowiring is by name. I did not use the autowire keyword in any XML files, but it's still autowiring. Based on this link, it looks like no autowiring should happen in this case.
Why is this happening? Can we set it at a global level somewhere in the project?

Spring bean autowire default value is “default” that means no autowiring is to be performed. autowire value “no” also have the same behavior.
The @Autowired annotation provides more fine-grained control over where and how autowiring should be accomplished. The @Autowired annotation can be used to autowire bean on the setter method just like @Required annotation, constructor, a property or methods with arbitrary names and/or multiple arguments.
@Bean is just for the metadata definition to create the bean(equivalent to tag). @Autowired is to inject the dependancy into a bean(equivalent to ref XML tag/attribute).
Dependency Injection is a fundamental aspect of the Spring framework, through which the Spring container “injects” objects into other objects or “dependencies”. Simply put, this allows for loose coupling of components and moves the responsibility of managing components onto the container.
The default autowiring in spring is by type

As this link describes
Default, no auto wiring, set it manually via “ref” attribute. In case of autodetect – If a default constructor is found, use “autowired by constructor”; Otherwise, use “autowire by type”.
