在过滤器标签apache骆驼上调用新类

Question

我的路由器类上有此代码

from("seda:singleInvoicesChannel")
                .filter(new LowEnoughAmountPredicate())
                .to("seda:filteredInvoicesChannel");

现在我试图与此转移到我的camel-context.xml

<route id="singleInvoicesChannel">
          <from uri="seda:singleInvoicesChannel"/>
          <filter>

          </filter>
          <to uri="seda:filteredInvoicesChannel"/>
      </route>

我的问题是我将在filter标记内放入什么以实现.filter（new LowEnoughAmountPredicate（））;。

Answer 1

我不喜欢这种Springish DSL，但我只是猜测可能是这样的：

<bean id="filterBean" class="LowEnoughAmountPredicate"/>

  <route id="singleInvoicesChannel">
      <from uri="seda:singleInvoicesChannel"/>
      <filter>
         <custom ref="filterBean" />
      </filter>
      <to uri="seda:filteredInvoicesChannel"/>
  </route>

Answer 2

正常的Spring解决方案如下所示：

  <bean id="myPredicate" class="LowEnoughAmountPredicate"/>

  <route id="singleInvoicesChannel">
      <from uri="seda:singleInvoicesChannel"/>
      <filter>
         <method ref="myPredicate"/>
         <to uri="seda:filteredInvoicesChannel"/>
      </filter>
  </route>
