使用 RestBindingMode.auto 获取 Camel 错误

Question

当运行 springboot Camel 与 maven 在下一行 .bindingMode(RestBindingMode.auto).

时出现错误

cannot find symbol
  symbol:   variable RestBindingMode
  location: class com.example.MySpringBootRouter

我是否遗漏了一些依赖性？我认为这应该不是问题，因为我的 pom.xml 中有下一个依赖项，但我不知道为什么会出现此错误。

        from("direct:route1")
                .convertBodyTo(String.class)
                .log("Boo!");
   }

}

如果我评论//.bindingMode(RestBindingMode.auto)骆驼启动OK。

Answer 1

正如 Luca 所说，我忘记在 MySpringBootRouter.java 中导入 RestBindingMode。

import org.apache.camel.model.rest.RestBindingMode

使用 RestBindingMode.auto 获取 Camel 错误
