Question

我有一个Flow需要字符串输入

  @Bean
  public IntegrationFlow myFlow() {
        // @formatter:off
        return IntegrationFlows.from("some.input.channel")
                               .handle(someService)
                               .get();

如何从集成测试中调用它，如何在“ some.input.channel”上放置字符串消息

阅读您使用的API的Javadocs：

function exportExcel($userList,$clientLogo,$defaultLogo){

// Generate and return the spreadsheet
            Excel::create('User_List', function ($excel) use ($userList,$clientLogo,$defaultLogo) {

                // Set the spreadsheet title, creator, and description
                $excel->setTitle('User List');
                $excel->setCreator('CompanyName')->setCompany('CompanyName');
                $excel->setDescription('User List Reports');

                    $excel->sheet('User List', function($sheet) use ($userList,$path,$clientLogo,$defaultLogo) {

                        //Set header with logo with different coloumn width & height
                        $objDrawing = new PHPExcel_Worksheet_Drawing;
                        $objDrawing->setPath(public_path('img/'.$defaultLogo));
                        $objDrawing->setCoordinates('A1');
                        $objDrawing->setWorksheet($sheet);
                        $objDrawing->setName('Client Logo');
                        $objDrawing->setResizeProportional(false);
                        $objDrawing->setWidth(100);
                        $objDrawing->setHeight(50);

                        $sheet->setSize('A1', 20, 50);

                        $objDrawing = new PHPExcel_Worksheet_Drawing;
                        $objDrawing->setPath(public_path('img/'.$clientLogo));
                        $objDrawing->setCoordinates('D1');
                        $objDrawing->setWorksheet($sheet);
                        $objDrawing->setName('Client Logo');
                        $objDrawing->setResizeProportional(false);
                        $objDrawing->setWidth(100);
                        $objDrawing->setHeight(50);

                        $sheet->setSize('D1', 20, 50);

                        $sheet->fromArray($userList, null, 'A2', false, false);

                        $sheet->cells('A1:D1', function($cells) {

                            $cells->setBackground('#36494F')->setFontColor('#FFFFF')->setFontWeight('bold');
                        });

                        $sheet->mergeCells('A1:D1');
                        $sheet->mergeCells('B1:C1');

                        $sheet->cell('B1', function($cell) {

                            $cell->setValue('User List')->setBackground('#36494F');
                        });

                        $sheet->row(1, function ($row) {

                            $row->setBackground('#36494F')->setFontColor('#FFFFFF')->setFontWeight('bold')->setValue('User Tickets List')->setAlignment('center')->setValignment('center');
                        });

                        $sheet->row(2, function ($row) {

                            $row->setBackground('#FFFFFF')->setFontColor('#36494F')->setFontWeight('bold')->setAlignment('center')->setValignment('center');
                        });

                        for ($i = 3; $i <= count($userList)+1; $i++) {

                            $sheet->cells('A'.$i.':D'.$i, function ($cells) use ($i) {

                                $cells->setBackground(($i%2) == 0 ? '#DCDCDC':'#EDEDEE');
                            });
                        }

                        for ($ascii = ord('A'); $ascii <= ord('D'); $ascii++) {

                            for ($i = 1; $i <= count($userList)+1; $i++) {

                                $sheet->cell(chr($ascii) . $i, function ($cell) {

                                    $cell->setBorder('thin','thin','thin','thin');
                                });
                            }
                        }

                    });


            })->download('xls');

}

然后打开您使用的框架的参考手册：

https://docs.spring.io/spring-integration/docs/current/reference/html/messaging-channels-section.html#messaging-channels-section

https://docs.spring.io/spring/docs/current/spring-framework-reference/testing.html#integration-testing-annotations-standard

因此，由Java DSL创建的通道在应用程序上下文中成为bean。将它们 autowire 插入测试类并从测试方法中调用其/** * Populate the {@link MessageChannel} name to the new {@link IntegrationFlowBuilder} chain. * The {@link org.springframework.integration.dsl.IntegrationFlow} {@code inputChannel}. * @param messageChannelName the name of existing {@link MessageChannel} bean. * The new {@link DirectChannel} bean will be created on context startup * if there is no bean with this name. * @return new {@link IntegrationFlowBuilder}. */ public static IntegrationFlowBuilder from(String messageChannelName) {就足够了：

send()
