在 Spring 启动时关闭 DispatcherServlet

Question

如何在 SpringBoot 上禁用 DispatcherServlet，甚至尝试通过 servlet 注册禁用它，uri 映射出现在日志中：

@Bean
public ServletRegistrationBean servletRegistrationBean(final DispatcherServlet dispatcherServlet) {
    final ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(dispatcherServlet);
    servletRegistrationBean.setEnabled(false);

    return servletRegistrationBean;
}

日志

2015-06-10 10:39:57.552  INFO 7032 --- [           main] o.s.b.c.e.ServletRegistrationBean        : Servlet dispatcherServlet was not registered (disabled)
2015-06-10 10:39:57.553  INFO 7032 --- [           main] o.s.b.c.e.ServletRegistrationBean        : Mapping servlet: 'dispatcherServlet' to [/]

感谢任何帮助！

Answer 1

来自 Spring 引导文档 here

Spring Boot wants to serve all content from the root of your application / down. If you would rather map your own servlet to that URL you can do it, but of course you may lose some of the other Boot MVC features. To add your own servlet and map it to the root resource just declare a @Bean of type Servlet and give it the special bean name dispatcherServlet (You can also create a bean of a different type with that name if you want to switch it off and not replace it).

Answer 2

我将下面的代码添加到我的主 class 中，然后从日志中删除了 servlet。

@SpringBootApplication(exclude = { DispatcherServletAutoConfiguration.class })

Answer 3

如果排除 DispatcherServletAutoConfiguration.class，那么你也需要排除 ErrorMvcAutoConfiguration.class，或者至少我排除了。

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.servlet.DispatcherServletAutoConfiguration;
import org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.EnableAspectJAutoProxy;

@SpringBootApplication(exclude = { DispatcherServletAutoConfiguration.class, ErrorMvcAutoConfiguration.class})
@EnableAspectJAutoProxy
public class CoreApplication extends SpringBootServletInitializer {
    public static void main(String[] args) {
        SpringApplication.run(CoreApplication.class, args);
    }

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(CoreApplication.class);
    }
}
