java - 如何在基于 Spring 注释的 java 配置中设置 Activity 配置文件

Question

设置 Activity 配置文件，如 context.getEnvironment().setActiveProfiles( "DEV"); 这可以通过使用来实现

public class SpringWebInitializer implements WebApplicationInitializer
{

    public void onStartup( final ServletContext servletContext ) throws ServletException
    {
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.getEnvironment().setActiveProfiles("DEV" )

    }
}

但是在扩展 AbstractAnnotationConfigDispatcherServletInitializer 时。我们如何才能实现设置 Activity 配置文件？

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer
{
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

}

使用 spring.profiles.active 属性激活您的配置文件。

public class WebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[] { WebConfig.class };
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return null;
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.setInitParameter("spring.profiles.active", "DEV");
    }

}
