开发过程IDEA提示如将@RequestMapping(value="/abc" , method = “RequestMethod.POST”)替换成@PostMapping。现对@PostMapping的实现。
@PostMapping是一个复合注解,Spring framework 4.3引入了@RequestMapping注释的变体,以更好地表示带注释的方法的语义,作为@RequestMapping(method = RequestMethod.POST)的快捷方式。
也就是可以简化成@PostMapping(value="/abc" )即可,主要是方便识记。
下面很多方法都是对应着@RequestMapping的标记的别名。
@RequestMapping(value = “”, path = “”, params = “”, headers = “”,consumes = “”, produces = “”)
@Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) @Documented @RequestMapping(method = RequestMethod.POST) public @interface PostMapping { /** * RequestMapping 的别名, */ @AliasFor(annotation = RequestMapping.class) String name() default ""; /** *RequestMapping#value的别名, 默认为空字符串,一般需要自己填写 */ @AliasFor(annotation = RequestMapping.class) String[] value() default {}; /** * RequestMapping#path的别名 */ @AliasFor(annotation = RequestMapping.class) String[] path() default {}; /** * RequestMapping#params的别名 */ @AliasFor(annotation = RequestMapping.class) String[] params() default {}; /** * RequestMapping#headers的别名 */ @AliasFor(annotation = RequestMapping.class) String[] headers() default {}; /** * RequestMapping#consumes的别名 */ @AliasFor(annotation = RequestMapping.class) String[] consumes() default {}; /** * RequestMapping#produces的别名 */ @AliasFor(annotation = RequestMapping.class) String[] produces() default {}; }
其他变体如下:
@GetMapping、@PutMapping、@PatchMapping和@DeleteMapping,与@PostMapping实现类似
