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");
        }
    };
}

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
