我正在使用"react": "~0.12.2"
以下代码:
@RequestMapping("/")
@ResponseBody
private String home() throws ScriptException, IOException {
loadReact();
InputStream jsStream = resourceLoader.getResource("classpath:public/js/server.js").getInputStream();
engine.eval(new InputStreamReader(jsStream));
return engine.eval("renderServerside()").toString();
}
private void loadReact() throws ScriptException, IOException {
InputStream jsStream = resourceLoader.getResource("classpath:public/lib/react/react.js").getInputStream();
// React expects 'window' or 'global' to be set
engine.eval("var global = this");
engine.eval(new InputStreamReader(jsStream));
}
我的server.js看起来像这样:
function renderServerside() {
var MyComponent = React.createClass({
render: function () {
return React.DOM.h1(null, 'Hi, ' + this.props.msg)
}
});
return React.renderComponentToString(MyComponent({msg: 'World!'}));
}
得到这个例外:
javax.script.ScriptException: ReferenceError: "console" is not defined in <eval> at line number 18108] with root cause
jdk.nashorn.internal.runtime.ECMAException: ReferenceError: "console" is not defined
那么nashorn怎么能不提供控制台?
我厌倦了从这个页面实现基本示例:React with Nashorn
答案 0 :(得分:6)
Rhino之前它也没有提供。您可以使用类似
的方式实现自己的控制台console = {
log: print,
warn: print,
error: print
};
对于完整的控制台支持,您可能需要添加更多功能。请参阅:Console
