Question

我需要使用http方法LOCK和UNLOCK来实现调用。

当前spring的requestMethod仅支持

public enum RequestMethod {

    GET, HEAD, POST, PUT, PATCH, DELETE, OPTIONS, TRACE

}

如果使用LOCK和UNLOCK http指令调用spring app，如何实现一个@RestController方法？

您可以使用支持的方法（GET，HEAD，POST，PUT，PATCH，DELETE，OPTIONS，TRACE）进行此操作。这是内部调用post方法的方法：

@Configuration
public class WebMvcCofig extends WebMvcConfigurationSupport{

@Override
@Bean
public RequestMappingHandlerAdapter requestMappingHandlerAdapter() {
    final RequestMappingHandlerAdapter requestMappingHandlerAdapter = super.requestMappingHandlerAdapter();
    requestMappingHandlerAdapter.setSupportedMethods(
            "LOCK", "GET", "HEAD", "POST", "PUT", "PATCH", "DELETE", "OPTIONS", "TRACE"
    ); //here supported method

    return requestMappingHandlerAdapter;
}

@Bean
DispatcherServlet dispatcherServlet() {
    return new CustomHttpMethods();
}
}

自定义方法处理程序类。这里通常会调用post方法：

public class CustomHttpMethods extends DispatcherServlet {

@Override
protected void service(final HttpServletRequest request, final HttpServletResponse response) throws ServletException, IOException {
    if ("LOCK".equals(request.getMethod())) {
        super.doPost(request, response);
    } else {
        super.service(request, response);
    }
}

}

现在您可以通过以下方式请求映射：

@RequestMapping(value = "/custom")
ResponseEntity customHttpMethod(){
    return ResponseEntity.ok().build();
}

Spring REST RequestMethod如何映射http LOCK和UNLOCK RequestMapping？
