使用Spring@AliasFor注解自定义注解合并@Controller和@RequestMapping

如果只需要代码可以直接根据目录进行获取

知识点

魔法本源先附上官方文档

然后开始扒,作为一代初级程序员恐怖如斯…码来

码

• 自定义注解

  package com.ruoyi.common.annotation;
  
  import org.springframework.core.annotation.AliasFor;
  import org.springframework.stereotype.Controller;
  import org.springframework.web.bind.annotation.RequestMapping;
  import org.springframework.web.bind.annotation.RequestMethod;
  
  import java.lang.annotation.Documented;
  import java.lang.annotation.ElementType;
  import java.lang.annotation.Retention;
  import java.lang.annotation.RetentionPolicy;
  import java.lang.annotation.Target;
  
  /**
   * 合并@Controller和@RequestMapping
   *
   * @author 405
   */
  @Target({ElementType.TYPE, ElementType.METHOD})
  @Retention(RetentionPolicy.RUNTIME)
  @Controller
  @RequestMapping
  @Documented
  public @interface ControllerMapping {
  
      /**
       * Alias for {@link Controller#value}.
       */
      @AliasFor(annotation = Controller.class, value = "value")
      String controllerValue() default "";
  
      /**
       * Alias for {@link RequestMapping#name}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String name() default "";
  
      /**
       * Alias for {@link RequestMapping#value}.
       */
      @AliasFor(annotation = RequestMapping.class, value = "value")
      String[] requestMappingValue() default {};
  
      /**
       * Alias for {@link RequestMapping#path}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String[] path() default {};
  
      /**
       * Alias for {@link RequestMapping#method}.
       */
      @AliasFor(annotation = RequestMapping.class)
      RequestMethod[] method() default {};
  
      /**
       * Alias for {@link RequestMapping#params}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String[] params() default {};
  
      /**
       * Alias for {@link RequestMapping#headers}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String[] headers() default {};
  
      /**
       * Alias for {@link RequestMapping#consumes}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String[] consumes() default {};
  
      /**
       * Alias for {@link RequestMapping#produces}.
       */
      @AliasFor(annotation = RequestMapping.class)
      String[] produces() default {};
  }
  

• 测试代码

  @ControllerMapping(requestMappingValue = "/test")
  public class TestAnnotationController {
  
      @GetMapping
      @ResponseBody
      public String treeData() {
          return "Hello-World";
      }
  }
  

• 结果

  C:\Users\Admin>curl -X GET 127.0.0.1/test
  Hello-World
  

同理可以合并@Autowired和@Qualifier
