骆驼处理器的Mockito doAnswer导致split方法失败

Question

我有这条路线：

 public class SomeRoute {
     @OVerride
     public void configure() {
          from("direct:route1")
               .process(processor1)
               .split(body())
               .process(persistProcessor)
               ....    
     }
 }

为此测试类：

 public class SOmeRouteTest {
     Processor processor1Mock;
     @Before
     public void setUp() {
         processor1Mock = Mockito.mock(Processor1.class);
         testObj = new SomeRoute();
         testObj.setProcessor1(processor1Mock);  
     }

     @TEst
     public void test() {
         //Processor processor = MOckito.mock(Processor1.class);
         doAnswer((Answer) invocation -> {
             // something with Exchange
             Exchange ex = invocation.getARgumentAt(0, Exchange.class);
             ex.getIn().setBody(new ArrayList<String>);
             return null;
       }) 

       template.sendBody("route1", json);
     }
 }

。 现在，拆分不起作用，它直接进入persistProcessor。实际的Processor1正在生成类强制转换异常，因为persistProcessor期望使用String，但是路由将其传递给ArrayList。

请帮助。
