代码如下
@Test
public void janinoPerformanceTest4() throws Exception {
String rule = "(inValues(appProtocol, \"http,https\") " +
"&& inValues(direction, \"10,00\")) " +
"&& (destHostName != null) " +
"&& (eventCount != null) " +
"&& (bytesOut != null) " +
"&& (bytesIn != null)";
IExpressionEvaluator evaluator = CompilerFactoryFactory.getDefaultCompilerFactory().newExpressionEvaluator();
evaluator.setExpressionType(boolean.class);
evaluator.setExtendedClass(JaninoContainsIgnoreCaseFunction.class);
evaluator.setParameters(
new String[]{"httpVersion", "requestHeader", "direction"},
new Class[]{String.class, String.class, String.class}
);
evaluator.cook(rule);
Object[] arguments = {"/securityEyeLogType" + i, "/dataType/Add" + i,
"/appProtocol/NetWorkLayer" + i};
Object res = evaluator.evaluate(arguments);
System.out.println(res);
}
报错如下

这是因为你的bytesIn这个字段没有在下面传递new String[]{"httpVersion", "requestHeader", "direction"},.一一对应就好了。
