我正在我的应用程序中使用带有Sping Boot 的Apache Camel。目前我正在进行单元测试。
Java程式码

• 数据路由类

from("direct:getData")
.routeId("getData")
.bean(DataService.class, "processData")
.marshal().json(JsonLibrary.Jackson)
.end();

• 数据服务类

public Data processData() {
    return new Data("Hello World");
}

• 带有getter、setter和JacksontoString方法的数据类

private String value;

单元测试

• 基本驼峰上下文单位文本

public abstract class BaseCamelContextUnitTest extends CamelTestSupport
{
     @Autowired
     private DataService dataService;

     @Produce
     private ProducerTemplate producerTemplate;

     public CamelContext getCamelContext() {
         return camelContext;
     } 

     @Override
     protected Context createJndiContext() throws Exception {
         JndiContext context = new JndiContext();
         context.bind("dataService", dataService);
         return context;
     }

     @Test
     public void shouldProcessData() throws Exception {
          RouteDefinition routeDef = getCamelContext().getRouteDefinition("getData");
          routeDef.adviceWith((ModelCamelContext) getCamelContext(), new RouteBuilder() {

             @Override
             public void configure() throws Exception {
                  from("direct:getData")
                    .pipeline("bean:dataService?method=processData");
             }
     });

     getCamelContext().start();

     String responseData = "{"
        + "\"value\":\"Unit test success\""
        + "}";

     Object response = producerTemplate.sendBody("direct:getData",   ExchangePattern.InOut, null);

     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
((InputStreamCache) response).writeTo(byteArrayOutputStream);

     assertThat(new String(byteArrayOutputStream.toByteArray()), is(responseData));
     }
  }

我怎么嘲笑

.bean(DataService.class, "processData")

在单元测试中返回一个模拟数据对象，其默认字符串变量为“单元测试成功”，然后测试路由是否给予模拟对象，而不是返回带有“Hello World”字符串变量的对象？
