Spring 总是 REST return 404

Question

我使用 spring mvc 创建一个 rest web 服务。但是，我总是得到 404。我不知道哪里出错了。

这是我的初始化程序：

public class Initializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
    // TODO Auto-generated method stub
    return new Class<?>[] { RootConfig.class };
}

@Override
protected Class<?>[] getServletConfigClasses() {
    // TODO Auto-generated method stub
    return new Class<?>[] { WebConfig.class };
}

@Override
protected String[] getServletMappings() {
    // TODO Auto-generated method stub
        return new String[] { "/" };
    }

}

这是我的网络配置：

@Configuration
@EnableWebMvc
@ComponentScan("com.jh.dummy.web")
public class WebConfig extends WebMvcConfigurerAdapter {
    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResovler = new InternalResourceViewResolver();
        viewResovler.setPrefix("/");
        viewResovler.setSuffix(".html");
        viewResovler.setExposeContextBeansAsAttributes(true);
        return viewResovler;
    }

    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

}

这是我的其余服务器文件：

    @RestController
@RequestMapping("/v1/")
public class PositionService {
    @RequestMapping(value = "position", consumes = MediaType.APPLICATION_JSON_VALUE, method = POST)
    public void create(List<Map<String, String>> data) {
    }

    @RequestMapping(value = "position/{id:\d+}", produces = MediaType.APPLICATION_JSON_VALUE, method = GET)
    public void getById(@PathVariable("id") Long id) {
    }

    @RequestMapping(value = "position/title/{title:.+}/{start:\d{1,}}", produces = MediaType.APPLICATION_JSON_VALUE, method = GET)
    public void getByTitle(@PathVariable("title") String title,
            @PathVariable("start") int start) {
    }

@RequestMapping(value = "position/title/{title:.+}/address/{address:\w{1,}}/{start:\d{1,}}", produces = MediaType.APPLICATION_JSON_VALUE, method = GET)
public void getByTitleAndLocation(@PathVariable("title") String title,
        @PathVariable("address") String address, @PathVariable("start") int start) {

    }

    @RequestMapping(value = "position/address/{address:\w{1,}}/{start:\d{1,}}", produces = MediaType.APPLICATION_JSON_VALUE, method = GET)
    public void getByLocation(@PathVariable("address") String address,
            @PathVariable("start") int start) {
    }

    @RequestMapping(value = "position/company/{company:.{1,}}/{start:\d{1,}}", produces = MediaType.APPLICATION_JSON_VALUE, method = GET)
    public void getByCompany(@PathVariable("company") String company,
                @PathVariable("start") int start) {
        }

    }

请求如下：

我用curl测试的时候总是404，找不到哪里出错了。有什么想法吗？

Answer 1

我解决了问题。原来我需要将 /dummy/ 添加到 url 中。因此 url 将是 "localhost:8080/dummy/v1/position/v1"。但在我的其他项目案例中，我不需要将项目名称添加到虚拟项目中。我仍然不知道为什么这次我需要这样做。当我发现时，我会及时通知你。
