必須jre6才行，要不需要用開(kāi)源庫(kù)了
package script;
import javax.script.*;
/**

*/
public final class scriptMaster {
/**
* 運(yùn)行指定腳本
* @return 返回腳本值
*/
public int run() {
ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine engine = m.getEngineByExtension("js");
try{
engine.eval("var t=1;t++;");
engine.eval("t++;");
}catch(ScriptException ex){
return -1;
}
Float val = Float.parseFloat(engine.get("t").toString());
return val.intValue();
}
}
java調(diào)用javascript,而javascript內(nèi)部又調(diào)用了java的類庫(kù)。
public String now(){
ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine engine = m.getEngineByExtension("js");
try{
engine.eval("var t= new java.util.Date();");
}catch(ScriptException ex){
return (new Date()).toString();
}
return engine.get("t").toString();
}
