因业务场景需要,有时需要区分get和post请求
比如删除,尽量用post请求(公司规范为只使用get和post请求)
常用的删除:@Getmapping 后面加@PathVariable
定义的注解名为:@FewPostParam
源码如下:
import org.springframework.core.annotation.AliasFor;
import org.springframework.web.bind.annotation.ValueConstants;
import java.lang.annotation.*;
@Target(ElementType.PARAMETER)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface FewPostParam {
/**
* Alias for {@link #name}.
*/
@AliasFor("name")
String value() default "";
/**
* The name of the request parameter to bind to.
*
* @since 4.2
*/
@AliasFor("value")
String name() default "";
/**
* Whether the parameter is required.
* <p>Default is {@code true}, leading to an exception thrown in case
* of the parameter missing in the request. Switch this to {@code false}
* if you prefer a {@code null} in case of the parameter missing.
* <p>Alternatively, provide a {@link #defaultValue() defaultValue},
* which implicitly sets this flag to {@code false}.
*/
boolean required() default true;
/**
* The default value to use as a fallback when the request parameter value
* is not provided or empty. Supplying a default value implicitly sets
* {@link #required()} to false.
*/
String defaultValue() default ValueConstants.DEFAULT_NONE;
}
使用场景如下:
打包到依赖,就可以使用了
