java - 如何通过java中的搜索正确请求与请求参数的映射？

Question

我遇到一个问题，我试图使用请求参数请求 map ，基本上我需要对此网址 jobs?autocomplete=0100 执行 GET 请求，并且由于某种原因我得到我所有的 /jobs 相反，你能帮我解决这个问题吗？谢谢!

@RestController
//@RequestMapping(value = "/jobs", params = "autocomplete")
public class AutoCompleteController {

    private AutoCompleteService autoCompleteService;

    private EntityManager em;

    public AutoCompleteController(AutoCompleteService autoCompleteService, EntityManager em) {

        this.autoCompleteService = autoCompleteService;
        this.em = em;
    }


    @GetMapping(value = "/jobs", produces = "application/json")
    public List<AutoComplete> getSalary(
            @RequestParam(name= "autocomplete", required = true) String autocomplete,
            @PathVariable("jobClassCd") String jobClassCd) {

        return autoCompleteService.retrieveSalary(jobClassCd);

    }





    public void getAllSalaries(HttpServletResponse res, HttpServletRequest req) {

        Stream<AutoComplete> stream = autoCompleteService.retrieveAllSalaries();
        DataStreamUtility.streamObjects(stream, res, em);



    }


}

Service:

@Service
public class AutoCompleteService {


    private AutoCompleteRepository autocompleteRepository;

    public AutoCompleteService(AutoCompleteRepository autRepo) {
        this.autocompleteRepository = autRepo;
    }

    public List<AutoComplete> retrieveSalary(String jobClassCd) {
        List<AutoComplete> salaries = autocompleteRepository.findByJobClassCd(jobClassCd);


        if (salaries.size() <= 0) {
            throw new SalaryNotFoundException(jobClassCd);
        }

        return salaries;
    }


    public Stream<AutoComplete> retrieveAllSalaries() {

        return autocompleteRepository.streamAll();


    }



}

处理请求的方法必须有一个带有 @RequestParam 注解的参数:

获取本地主机:8080/jobs?job_id=456

@GetMapping("/jobs", produces = "application/json")
public Book getJob(@RequestParam("job_id") Long id) {
    return repo.findJobById(id);
}

因此，您的代码将如下所示:

@GetMapping("/jobs", produces = "application/json")
public List<AutoComplete> getSalary(
    @RequestParam("autocomplete", required = true) String autocomplete,
    @PathVariable("jobClassCd") String jobClassCd) {

    return autoCompleteService.retrieveSalary(jobClassCd);

}
