使用 spring 项目测试 JUnit 5 中的删除方法得到 "Name for argument of type [long] not specified" 错误

Question

我对 spring 和 JUnit 很陌生。现在我尝试构建一个测试用例。在我运行这个

  @Test
  public void shouldBeOK_Found() throws Exception {
    mockMvc.perform(MockMvcRequestBuilders.delete("/scores/{id}", 1L)
    ).andExpect(status().isOk());
  }

我得到这个错误跟踪。

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: Name for argument of type [long] not specified, and parameter name information not found in class file either.

这是我的控制器

  //Delete Score
  //DELETE /score/{id}
  @DeleteMapping("/scores/{id}")
  public ResponseEntity<Score> deleteScore(@PathVariable(required = true) long id) {
    Score result = null;
    try{
      Optional<ScoreEntity> s = scoreRepository.findById(id);
      if (s.isPresent()){
        result = new Score(s.get());
        scoreRepository.delete(s.get());
        return ResponseEntity.status(HttpStatus.OK).body(result);
      }
    }catch (Exception e){
      System.out.println(e);
      return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
    }
    return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
  }

请帮忙。提前谢谢你。

如果您的代码没有使用 -parameter for Java 8 doc.

编译，您需要在注释中定义名称

You can explicitly name URI variables (for example, @PathVariable("customId")), but you can leave that detail out if the names are the same and your code is compiled with debugging information or with the -parameters compiler flag on Java 8.

@PathVariable(required = true, name="id") long id
