我試圖將一個類導入到MVEL的實現中，並且出現以下錯誤：錯誤：類型爲com.MyApp.Main的預期接收者，但得到java.lang.Class <com.MyApp.Main>
[錯誤：類型com.MyApp.Main的預期接收器，但得到的java.lang.Class]
下面是設置MVEL方法：
public void runCode() {
final String theCode = "Main.sendText();";
System.setProperty("java.version", "1.6");
new Thread(new Runnable() {
public void run() {
ParserContext context = new ParserContext();
context.addImport("Main", Main.class);
Serializable compiled = MVEL.compileExpression(theCode, context); // compile the expresion
HashMap vars = new HashMap();
vars.put("x", new Integer(10));
vars.put("y", new Integer(10));
Integer result = (Integer) MVEL.executeExpression(compiled, vars);
}
}).start();
}
Main.class：
public void sendText(){
System.out.println("Success!");
}
的logcat：
