java – Spring MVC Diffrence between Path & Variable in @RequestMapping Annotation

java – Spring MVC Diffrence between Path & Variable in @RequestMapping Annotation

Theres no difference between @RequestMapping(/home) and @RequestMapping(value = /home).But if you want to add some other parameter then you have to use,

@GetMapping(value = /home/{ABC}, consumes = MediaType.ALL_VALUE)

because if write,

@GetMapping(/getTodayActivity/{millis}, consumes = MediaType.ALL_VALUE)

then it will compile error, so only want to use more parameter then you have to use value

According to this there is no difference between @RequestMapping(/home) and @RequestMapping(value = /home) when you are using to class level or method level.

However, you can use pass more than one variable with this usage @RequestMapping(value={/method1,/method1/second})

java – Spring MVC Diffrence between Path & Variable in @RequestMapping Annotation

Theres no difference between @RequestMapping(/home) and @RequestMapping(value = /home). You can quickly use the former if theres only one mapping, and latter if there are multiple URLs that are being mapped to same place, for example, @RequestMapping(value={/home,/home2,/home2/home3})

Similarly, the path and value are also same. If you look at their definitions, they are basically alias of each other:

definition of value:

@AliasFor(value=path)
public abstract java.lang.String[] value
    ...

definition of path:

@AliasFor(value=value)
public abstract java.lang.String[] path
    ...

As for all the definitions, you can always visit the official docs.
