我正在将Camel REST与Camel servlet一起使用,以处理REST传输,并希望更改在HTTP请求和响应中处理来自交换器的报头的方式。我正在使用Spring XML来配置我的应用程序。这是我正在使用的相关配置:
protected override async void OnStartup(StartupEventArgs e)
{
await host.StartAsync();
var mainWindow = host.Services.GetRequiredService<MainWindow>();
mainWindow.Show();
base.OnStartup(e);
}
创建路由后,我看到端点配置为<?xml version="1.0" encoding="UTF-8"?>

<camel:corsHeaders key="Access-Control-Allow-Headers" value="*"/>

</beans>
。但是,传入的请求仍在使用MyHttpBinding
。这是因为当Camel创建使用者时,它将执行以下代码块:
ServletRestHttpBinding
如何以骆驼尊重的方式设置HTTP绑定?
答案 0 :(得分:1)
由于骆驼最终在端点上寻找httpBinding
属性以确定要使用的绑定策略,因此必须配置REST组件以将该属性添加到端点,如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd">
<!-- Custom Camel Configuration //////////////////////////////////////////////////////////////////////////////// -->
<bean id="myHttpBinding" class="com.example.MyHttpBinding"/>
<!-- Routes //////////////////////////////////////////////////////////////////////////////////////////////////// -->
<camel:camelContext id="myCamelContext">
<camel:contextScan/>
<camel:restConfiguration component="servlet" enableCORS="true" bindingMode="json" skipBindingOnErrorCode="false">
<camel:endpointProperty key="httpBinding" value="myHttpBinding"/>
<camel:corsHeaders key="Access-Control-Allow-Methods" value="PATCH, PUT, POST, DELETE, GET, OPTIONS, HEAD"/>
<camel:corsHeaders key="Access-Control-Allow-Origin" value="*"/>
<camel:corsHeaders key="Access-Control-Allow-Headers" value="*"/>
</camel:restConfiguration>
</camel:camelContext>
</beans>
请注意,我删除了自定义servlet组件,因为它不是必需的。
