最简单的用法，展示可勾选，可选中，禁用，默认展开等功能。

import { Tree } from 'antd';
const TreeNode = Tree.TreeNode;

const Demo = React.createClass({
  getDefaultProps() {
    return {
      keys: ['0-0-0', '0-0-1'],
    };
  },
  getInitialState() {
    const keys = this.props.keys;
    return {
      defaultExpandedKeys: keys,
      defaultSelectedKeys: keys,
      defaultCheckedKeys: keys,
    };
  },
  onSelect(info) {
    console.log('selected', info);
  },
  onCheck(info) {
    console.log('onCheck', info);
  },
  render() {
    return (
      <Tree className="myCls" showLine multiple checkable
        defaultExpandedKeys={this.state.defaultExpandedKeys}
        defaultSelectedKeys={this.state.defaultSelectedKeys}
        defaultCheckedKeys={this.state.defaultCheckedKeys}
        onSelect={this.onSelect} onCheck={this.onCheck}>
        <TreeNode title="parent 1" key="0-0">
          <TreeNode title="parent 1-0" key="0-0-0" disabled>
            <TreeNode title="leaf" key="0-0-0-0" disableCheckbox />
            <TreeNode title="leaf" key="0-0-0-1" />
          </TreeNode>
          <TreeNode title="parent 1-1" key="0-0-1">
            <TreeNode title={<span style={{ color: '#08c' }}>sss</span>} key="0-0-1-0" />
          </TreeNode>
        </TreeNode>
      </Tree>
    );
  },
});

ReactDOM.render(<Demo />, mountNode);
