[英]Link spring boot with react
我按照本教程使用react和spring boot創建了一個Web應用程序。
我按照完全相同的步驟,但在我的反應應用程序中,我介紹了webpack。 react應用程序已啟動並正在運行。
pom.xml文件如下所示:
<?xml version="1.0" encoding="UTF-8"?>

我完成了本教程的最后幾步:
mvn clean package
java -jar target/cra-demo-0.0.1-SNAPSHOT.jar
但我看到我的彈簧服務器已關閉:
:: Spring Boot :: (v1.5.3.RELEASE)

我是新手並且做出反應,我不知道如何讓spring服務器啟動並運行並與我的react應用程序進行交互。
編輯:在pom.xml中我有:
<directory>src/main/app/build/</directory>
我使用webpack -p創建生成版本但我看不到構建文件夾。 如何在構建文件夾中生成生成構建?
你介紹了webpack女巫一點也不差,你可以做些什么來簡化你的React應用程序的使用春天,是設置Webpack代理來攔截特定端口中的所有HTTP請求,這就是我這樣做的方法:
'webpack-dev-server': {
options: {
webpack: webpackConfig,
inline: true,
},
start: {
host: '0.0.0.0',
port: '<%= config.webpackDevServerPort %>',
contentBase: '<%= config.dist %>',
webpack: {
devtool: 'inline-source-map',
debug: true,
},
proxy: {
'/myapp': {
target: 'http://localhost:' + (grunt.option('proxy-port') || config.connectPort),
secure: false,
},
},
},
},
在Spring應用程序中,最后一件事就是允許以下內容:
/**
* Register WebSocket publisher
*
* @param registry where the handler will be registered
*/
@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
registry.addHandler(publisher, webSocketPath).setAllowedOrigins("*");
}
如果你沒有setAllowedOrigins("*");
來自外部spring服務器的rest調用不會被攔截,這只是針對開發人員,並且必須在應用程序投入生產時被禁用。
