Webpack-Babel-JSXの解析：SyntaxError：予期しないトークン

webpackを使用してReactアプリケーションを作成しようとしています。私はbabelを使用して.jsxファイルをトランスパイルしています。しかし、.jsxファイルをロードするためにbabelローダーを使用していないようです。次のエラーが発生します：

ERROR in ./app.jsx
Module parse failed: C:\codebase\react-demo/app\app.jsx Unexpected token (7:15)
You may need an appropriate loader to handle this file type.

私のwebpack.config.jsように見えます：

var webpack = require('webpack');
var path = require('path');
var HtmlWebpackPlugin = require('html-webpack-plugin');

var __dirname = path.resolve();

module.exports = {
    context: __dirname + "/app",
    entry: "./app.jsx",
    output: {
        path: __dirname + "/dist/",
        filename: "bundle.min.js"
    },
    loaders: [{
        test: /\.jsx?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
    }],
    plugins: [
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin({ mangle: false, sourcemap: false }),
        new HtmlWebpackPlugin({
            template: 'index.html'
        })
    ],
};

私のapp.jsx（./ app / app / jsxにあります）は次のとおりです。

import React from 'react';
import ReactDOM from 'react-dom';

class App extends React.Component {

    render() {
        return <div > Test < /div>;
    }
}

ReactDOM.render(<App/>, document.getElementById('app'));

私は以下を持っています.babelrc：

{
    "presets": ["es2015", "stage-0", "react"]
}

次のノード依存関係がインストールされています：

"devDependencies": {
    "babel-core": "^6.13.2",
    "babel-loader": "^6.2.4",
    "babel-preset-es2015": "^6.13.2",
    "babel-preset-react": "^6.11.1",
    "babel-preset-stage-0": "^6.5.0",
    "html-webpack-plugin": "^2.22.0",
    "react": "^15.3.0",
    "react-dom": "^15.3.0",
    "webpack": "^1.13.1",
    "webpack-dev-server": "^1.14.1"
}

何が欠けているのでしょうか？
