spring动态注册控制器路由
问题中展示的代码可以实现路由注册,但由于参数类型写死了userdto.class,无法动态化。
要实现这一点,可以使用Java反射机制获取方法的参数类型。以下是一个示例:
package dry.example.service.impl; import dry.example.route.CustomInvocationHandler; import dry.example.route.RouteAdmin; import dry.example.service.RouteService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.mvc.method.RequestMappingInfo; import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping; import java.lang.reflect.Method; import java.lang.reflect.Proxy; @Service public class RouteServiceImpl implements RouteService { @Autowired private RequestMappingHandlerMapping requestMappingHandlerMapping; @Override public void run(Object handler) { try { RequestMappingInfo requestMappingInfo = RequestMappingInfo.paths("testing").methods(RequestMethod.GET).build(); Method method = handler.getClass().getMethod("h01", getParameterType(handler, "h01")); requestMappingHandlerMapping.registerMapping(requestMappingInfo, handler, method); } catch (Exception e) { e.printStackTrace(); } } private Class<?> getParameterType(Object handler, String methodName) throws NoSuchMethodException { Method method = handler.getClass().getMethod(methodName); return method.getParameterTypes()[0]; } }
在示例中,getparametertype 方法通过反射获取指定方法的第一个参数类型,从而实现参数类型的动态化。
