小编Mar*_*ski的帖子

我是Spring Boot的新手,但经过几个小时的阅读关于Spring Boot REST中的异常handlig的帖子和博客,没有人写任何关于处理从自定义Converter抛出的异常的事情,我决定写这里.

我开发了基于Spring Boot的小型REST应用程序,它只是从IntelliJ生成的.示例性方法看起来像这样

@RestController
@RequestMapping("/resources")
public class CVResourceService {

    private final TechnologyRepository technologyRepository;
    private final ProjectRepository projectRepository;

    @Autowired
    public CVResourceService(TechnologyRepository technologyRepository,     ProjectRepository projectRepository) {
        this.technologyRepository = technologyRepository;
        this.projectRepository = projectRepository;
    }

    @RequestMapping(value = "/users/{guid}/projects/langs/{lang}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public Collection getUserProjects(@PathVariable("guid") GUID userGUID,         @PathVariable("lang") Language language) {
        return  ProjectDTOAssembler.toDTOs(projectRepository.findOne(userGUID, language));
    }
}

因为这两个guid和lang是字符串,我想这条信息来自同一begining强类型,我创建了简单的转换器GUID和Language类型和应用类注册吧:

public final class GUIDConverter implements Converter{

    @Override
    public GUID convert(String source) {
        return …
