基于Java的Azure函数的服务总线输出绑定不工作没有错误

Question

我尝试构建基于Java的Azure函数，由HTTP触发，并将数据发送到服务总线的主题。这是基于示例代码。HTTP触发器工作正常（返回Hello name），但我没有收到任何发送到服务总线的数据。我没有收到错误信息。我已经用基于C#的函数进行了测试，该函数在本地。设置。json是正确的

    @FunctionName("HttpTriggerSBOutputJava")
    public HttpResponseMessage run(

        final ExecutionContext context) {

        String name = request.getBody().orElse("Azure Functions");

        message.setValue(name);
        return request.createResponseBuilder(HttpStatus.OK).body("Hello, " + name).build();

    }
