如何将自定义ApplicationContextInitializer添加到Spring Boot应用程序? [英] How to add custom ApplicationContextInitializer to a spring boot application?

问题描述

将自定义ApplicationContextInitializer添加到Spring Web应用程序的一种方法是将其添加到web.xml文件中，如下所示.

One way to add custom ApplicationContextInitializer to spring web application is to add it in the web.xml file as shown below.

<context-param>
    <param-name>contextInitializerClasses</param-name>
    <param-value>somepackage.CustomApplicationContextInitializer</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

但是，由于我使用的是Spring Boot，是否有任何方法不必创建web.xml来添加CustomApplicationContextInitializer?

But since I am using spring boot, is there any way I don't have to create web.xml just to add CustomApplicationContextInitializer?

推荐答案

您可以在META-INF/spring.factories

org.springframework.context.ApplicationContextInitializer=\
com.example.YourInitializer

您还可以在运行前将它们添加到SpringApplication上

You can also add them on your SpringApplication before running it

application.addInitializers(YourInitializer.class);
application.run(args);

或者在构建器上

new SpringApplicationBuilder(YourApp.class)
    .initializers(YourInitializer.class);
    .run(args);

乍看之下从文档中看不出来，所以我打开了#5091 检查.

It wasn't obvious from the doc at first glance so I opened #5091 to check.
