Difference between Explicit and Auto Wiring in the Spring

Explicit Wiring	Auto Wiring
1. Explicit Wiring means hard-coding the dependencies in the XML.	1. Not hard-coding in the XML file rather Container to detect and inject Dependencies.
2. Mainly it can be done in two ways     a. Constructor   b. Setter injection	2. It can be done in four ways  a. byName     b. byType c. constructor  d. autodetect
3. It requires writing more content in the XML which ultimately makes XML little complex.	3. It doesn't require much writing rather need just any of the four value to the autowire attribute.
