从简单的语言表达式执行bean方法的转换错误
Convertation error in bean method execution from simple language expression
我想在 XML DSL 中将交换 header 设置为执行 bean 方法的结果。我在这个问题的评论中找到了解决方案 - Camel - Passing specific parameters from routes to a generic bean method，我的代码是
XML DSL:
<setHeader headerName="dateInterval">
<simple>${bean:tableRequestRouteUtil?method=getIntervalForTable(${in.body})}</simple>
</setHeader>
此时的 body 类型是我的 domain-specific POJO (class webbanking.dto.W4MMsg)。 body的初始类型是XMLString，然后转换为POJO（JAXB注解）：
<dataFormats>
<jaxb id="xml" prettyPrint="true"
contextPath="dto"/>
</dataFormats>
在蓝图中xml
和
<unmarshal ref="xml" id="xml.unmarshall"/>
骆驼路线
tableRequestRouteUtil bean 的 getIntervalForTable 方法的参数类型为 webbanking.dto.W4MMsg（我的 pojo），return 类型为 String。这工作正常，直到输入 xml 没有出现右括号。输入字符串中的右括号导致以下异常（我省略了请求的 body，它相当大）：

我认为这是因为简单的语言表达式执行bean方法的方式是将消息转换为字符串，用这个字符串替换占位符${in.body}，然后执行方法，将这个字符串转换回POJO使用转换器框架。此字符串中存在右括号会中断 body 消息，因为它被解释为方法参数的右括号。这是真的？有什么办法可以解决这个问题？从 bean 的执行设置 header 的正确方法应该是什么？
尝试不使用主体，因为 Camel 会自动绑定到参数，而主体是默认绑定的
method=getIntervalForTable
然后不要使用()，这样你只告诉Camel方法名，它可以使用有参数的方法。
我还认为我们已经在即将推出的 Camel 2.15.1 中用 bean 语言修复了 () iusse

我认为这是因为简单的语言表达式执行bean方法的方式是将消息转换为字符串，用这个字符串替换占位符${in.body}，然后执行方法，将这个字符串转换回POJO使用转换器框架。此字符串中存在右括号会中断 body 消息，因为它被解释为方法参数的右括号。这是真的？有什么办法可以解决这个问题？从 bean 的执行设置 header 的正确方法应该是什么？
尝试不使用主体，因为 Camel 会自动绑定到参数，而主体是默认绑定的
method=getIntervalForTable
然后不要使用()，这样你只告诉Camel方法名，它可以使用有参数的方法。
我还认为我们已经在即将推出的 Camel 2.15.1 中用 bean 语言修复了 () iusse
