Question

我无法弄清楚这部分代码是如何抛出NoSuchMethodException的。有人可以帮忙吗？方法M ...行可能是代码错误的地方。方法getMethod被破坏或我使用它错了。如果您需要更多文件，请询问。谢谢！

floorName = "Base";
try {
        Class[] cArg = new Class[5];
        cArg[0] = World.class;
        cArg[1] = Integer.class;
        cArg[2] = Integer.class;
        cArg[3] = Integer.class;
        cArg[4] = String.class;
        Method m = TowerFloors.class.getMethod("genFloor_" + floorName.toLowerCase(), cArg); //Probable Origin of Throwable Error
        try {
            done = (Boolean) m.invoke(m, x, y, z, color);
            success = done;
        } catch (Exception e) {
            DungeonMod.logger.log(Level.ERROR, "Error in generating tower floor \"" + floorName + "\"(" + e + "), generating \"Base\" floor instead.");
            done = genFloor_base(worldA, x, y, z, color);
        }
    } catch (Exception e) {
        DungeonMod.logger.log(Level.ERROR, "Error in generating tower floor \"" + floorName + "\"(" + e + "), generating \"Base\" floor instead.");
        done = genFloor_base(worldA, x, y, z, color);
    }

以下是方法：

 public static boolean genFloor_base(World world, int i, int j, int k, String color) {
    if (color.toLowerCase().equals("blue")) {
        //Floor
        BlockFill.fillRectangle(world, i - 10, j, k - 10, i + 10, j, k + 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        //Roof
        BlockFill.fillRectangle(world, i - 10, j + 5, k - 10, i + 10, j + 5, k + 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        //++Wall
        BlockFill.fillRectangle(world, i + 10, j + 1, k + 10, i + 10, j + 4, k - 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        //--Wall
        BlockFill.fillRectangle(world, i - 10, j + 1, k - 10, i - 10, j + 4, k + 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        //+-Wall
        BlockFill.fillRectangle(world, i + 10, j + 1, k - 10, i - 10, j + 4, k - 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        //-+Wall
        BlockFill.fillRectangle(world, i - 10, j + 1, k + 10, i + 10, j + 4, k + 10, TowerDungeonBuildingBlocks.towerDungeonWallBlue);
        return true;
    }
    return false;
}

（是的，这是一个Minecraft mod）

Answer 1

你的方法

public static boolean genFloor_base(World world, int i, int j, int k, String color) {

有5个参数，其中i，j和k属于int类型。

你想要使用

int.class

而不是

Integer.class

识别参数类型。

class.getMethod（）在我的上下文中不起作用
