groovyimportjava_Java和Groovy脚本互相调用实例

本实例是GODU动态脚本的一个技术简化版&＃xff0c;演示了java调groovy&＃xff0c;groovy又调java的运行过程。 测试用例&＃xff1a; package com.boco.godu.integration;

import java.util.HashMap;

import java.util.Map;

import org.apache.log4j.Logger;

import org.junit.After;

import org.junit.AfterClass;

import org.junit.Before;

import org.junit.BeforeClass;

import org.junit.Test;

import com.boco.godu.gapi.ConnManager;

import com.boco.godu.gapi.Constants;

import com.boco.godu.gapi.IConnection;

import com.boco.godu.gapi.IResult;

public class SimpleExpScriptTest {

private static final Logger logger &＃61; Logger

. getLogger (SimpleExpScriptTest. class );

private IConnection conn ;

&＃64;Before

public void setUp() throws Exception {

conn &＃61; ConnManager. getDataConn ( "10.0.2.47" , 1234,

"<7001>" , "goduapp" ,

Constants. TYPE_DATA_CMD_SYNC , 5);

}

&＃64;After

public void tearDown() throws Exception {

conn .close();

}

&＃64;Test

public void testImport() throws Exception {

Map params &＃61; new HashMap();

params.put( "cmd1" , "ls" );

params.put( "id" , 3);

IResult result &＃61; conn .execScript( "ImportEx" , params);

}

}

Java代码&＃xff1a;

IConnection.java

package com.boco.godu.gapi;

public interface IConnection {

......// other method definition

public IResult execScript (String name, Map params)

throws Exception;

}

GoduDataConnection.java

package com.boco.godu.gapi.conn;

public class GoduDataConnection extends AbstractConnection {

......// Other IConnection Methods

public IResult execScript(String name, Map params)

throws Exception {

String[] roots &＃61; new String[] { "e:/MyDoc/Project/GoduScript" };

GroovyScriptEngine gse &＃61; new GroovyScriptEngine(roots);

Binding binding &＃61; new Binding();

for (Entry item : params.entrySet()) {

binding.setVariable(item.getKey(), item.getValue());

}

GapiIosessionUtils giu &＃61; new GapiIosessionUtils();

binding.setVariable( "giu" , giu );

gse.run(name, binding);

System. out .println(binding.getVariable( "result" )); // 运行结果是这里输出“11”&＃xff0c;即3*2&＃43;5。

return null ;

}

}

GapiIosessionUtils.java

package com.boco.godu.gapi.util;

public class GapiIosessionUtils {

......// other method

public int testM( int x, int y) {

return x * 2 &＃43; y;

}

}

groovy代码&＃xff1a;

e:\MyDoc\Project\GoduScript\ImportEx

def send(cmd){

def result &＃61; giu.testM(cmd,5);

return result;

}

result &＃61; send(id)

运行过程

测试用例 ->GoduDataConnection.java -> groovy代码 -> GapiIosessionUtils.java&＃xff1b;

总结

binding的setVariable中定义的变量(如giu是com.boco.godu.gapi.util.GapiIosessionUtils对象&＃xff0c;id是int型数据)在groovy脚本里直接使用&＃xff0c;可以出现在脚本的任何地方&＃xff0c;且无需声明类型&＃xff0c;无需使用import导入定义该变量的类(例如对于giu来说&＃xff0c;如果在java代码中&＃xff0c;需要import com.boco.godu.gapi.util.GapiIosessionUtils)。
