java調用、執行groovy代碼

1: package test; 2: ? 3: import javax.script.ScriptEngine; 4: import javax.script.ScriptEngineManager; 5: import javax.script.ScriptException; 6: ? 7: public class ScriptExcuteUtil { 8: ? 9: public ScriptExcuteUtil() { 10: ? 11: } 12: ? 13: /** 14: * @param args 15: */ 16: public static void main(String[] args) { 17: ScriptEngineManager manager = new ScriptEngineManager(); 18: ScriptEngine engine = manager.getEngineByName("groovy"); 19: try { 20: System.out.println("calling groovy from java start"); 21: engine.put("name", "VerRan"); 22: engine.eval("println \"${name}\"+\"你好\";name=name+'！'"); 23: System.out.println(engine.get("name")); 24: System.out.println("calling groovy from java end"); 25: 26: engine.eval(""); 27: } catch (ScriptException e) { 28: e.printStackTrace(); 29: } 30: } 31: ? 32: } ? ? 1: package test; 2: ? 3: import groovy.lang.GroovyClassLoader; 4: import java.io.File; 5: ? 6: public class InvokeGroovy { 7: public static void main(String[] args) { 8: ClassLoader cl = new InvokeGroovy().getClass().getClassLoader(); 9: GroovyClassLoader groovyCl = new GroovyClassLoader(cl); 10: try { 11: // 從文件中讀取 12: Class groovyClass = groovyCl.parseClass(new File( 13: "C:\\mysource2\\GroovyLearn\\groovy\\fist\\Foo.groovy")); 14: Class groovyClass2 = groovyCl 15: .parseClass("package org.openjweb.groovy; \r\n import test.IFoo;\r\n class Foo implements IFoo {public Object run(Object foo) {return ((Integer)foo).intValue()+3}}"); 16: ? 17: IFoo foo = (IFoo) groovyClass.newInstance(); 18: System.out.println(foo.run(new Integer(2))); 19: ? 20: IFoo foo2 = (IFoo) groovyClass2.newInstance(); 21: System.out.println(foo2.run(new Integer(2))); 22: ? 23: } catch (Exception e) { 24: e.printStackTrace(); 25: } 26: } 27: } ClassLoader?的另一種方式

ClassLoader parent = ClassLoader.getSystemClassLoader();

GroovyClassLoader loader =?new?GroovyClassLoader(parent);
