直接能够穿一个字符串执行
private static void test(String pm1) {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("js");
Object result;
try {
result = engine.eval(pm1);
System.out.println("a + b = " + result);
} catch (ScriptException e) {
e.printStackTrace();
}
}
