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。
