Example 49 with MethodParameter

use of org.springframework.core.MethodParameter in project java-chassis by ServiceComb.

the class ParamUtils method getParameterName.

public static String getParameterName(Method method, int paramIdx) {
    MethodParameter methodParameter = new MethodParameter(method, paramIdx);
    methodParameter.initParameterNameDiscovery(parameterNameDiscoverer);
    String paramName = methodParameter.getParameterName();
    if (paramName == null) {
        // 小于jdk8的场景中，即使有debug参数，也无法对着interface获取参数名，此时直接使用arg + paramIndex来表示
        paramName = "arg" + paramIdx;
    }
    return paramName;
}
