ant+Junit的单元测试无法启动spring容器

以下junit的单元测试启动了Spring容器，在eclipse运行正常

@Test
public void add(){
System.out.println("Spring begin");
ApplicationContext ac = new ClassPathXmlApplicationContext(
"applicationContext.xml");
final ISpiderService jdtuhu = (ISpiderService) ac.getBean("JdTuhuService");
System.out.println(jdtuhu.toString());
jdtuhu.work();
}

但是用Ant 脚本调用junit时无法加载spring容器，有解决同样问题的吗？

<?xml version="1.0" encoding="UTF-8"?>

<target name="junit">
        <junit fork="true" printsummary="yes" forkmode="once" jvm="F:\Java\jdk1.6\bin\java.exe">

                <pathelement path="bin" />
                <fileset dir="lib">
                    <include name="**/*.jar" />
                </fileset>
            </classpath>
            <batchtest fork="yes">
                <fileset dir="src">
                    <include name="**/*JunitTest.java" />
                </fileset>
            </batchtest>
        </junit>
</target>
