如何在spring-boot中设置context-param [英] How to set context-param in spring-boot

问题描述

在经典的web.xml类型配置中，您可以像这样配置上下文参数

In the classic web.xml type configuration you could configure context parameters like so

web.xml

...
<context-param>
  <param-name>p-name</param-name>
  <param-value>-value</param-value>
</context-param>
...

这在spring-boot中是如何实现的.我有一个需要参数的过滤器.

How is this achieved in spring-boot. I have a filter that requires parameters.

我正在使用@EnableAutoConfiguration，并且在我的pom中包含了<artifactId>spring-boot-starter-jetty</artifactId>.

I'm using @EnableAutoConfiguration and have included <artifactId>spring-boot-starter-jetty</artifactId> in my pom.

推荐答案

您可以通过声明ServletContextInitializer bean来对整个ServletContext设置参数:

You can set parameters on the whole ServletContext by declaring a ServletContextInitializer bean:

@Bean
public ServletContextInitializer initializer() {
    return new ServletContextInitializer() {

        @Override
        public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("p-name", "-value");
        }
    };
}

更新:在Spring Boot 1.2中，不再需要使用ServletContextInitializer.现在，您可以在application.properties的单行中的ServletContext上配置参数:

Update: in Spring Boot 1.2 using a ServletContextInitializer is no longer necessary. You can now configure a parameter on the ServletContext in a single line in application.properties:

server.context_parameters.p-name=-value
